That finding is evidence of limited skill transfer—not proof that simulator-only training prepares every learner for every job. Practice and assessment on the actual machine remain necessary to evaluate performance in real operating conditions.
What is the difference between simulator training and field training?
Simulator training lets a learner operate virtual controls and perform excavator tasks in a simulated environment. Field training puts the learner on an actual excavator. The distinction is not simply “screen versus machine”: the setting determines what equipment the learner handles, what task is practiced, and whether performance is assessed on real equipment.

Both methods can support practice, but the available evidence does not establish that they are interchangeable. Simulator studies show that learners can practice defined equipment-control tasks and that some practiced skills can transfer to a real excavator. Field practice offers the opportunity to operate and be assessed on the actual machine. No cited study establishes a universal simulator-to-field hour ratio or a complete list of competencies that can only be learned in the field.

When comparing programs, ask what the learner will actually do in each setting. A simulator curriculum may focus on a single control task, rotate through separate modules, or combine several task components. A field session should give the learner an opportunity to operate the equipment that matters to the assignment and let an instructor evaluate that performance. The available studies do not provide a standard checklist, so these are planning questions rather than universal requirements.
What can an excavator simulator teach?
Practice with defined control tasks
The cited experiments used simulated practice for tasks including carrier positioning, trenching and truck loading. A simulator can therefore provide a place to rehearse equipment-control tasks without operating a working excavator. The studies support that these tasks can be practiced in simulation; they do not quantify how much money or equipment time simulation saves, or establish a universal safety benefit.
How useful a session is depends on what the learner actually practices. A simulator session devoted to a specific task is not automatically equivalent to broad operating experience. Before treating simulator time as preparation for a job, ask which controls and tasks the learner will use, how progress is evaluated, and whether the next stage includes assessment on the machine intended for the work.
Simulator practice can also make it easier to repeat a defined exercise. Repetition is only meaningful, however, if the exercise and feedback match the skill being taught. Completing a simulated task is not, by itself, proof that the learner can perform it at the required level on an actual excavator. The cited studies do not establish a universal scoring system or pass mark for simulator exercises.
Component practice as well as whole-task practice
A 2013 experiment compared separate simulator modules for carrier positioning, trenching and truck loading with practice on a combined trench-and-load task. On a retention test after a two-week interval, the part-task group had higher productivity than the whole-task group. This is evidence about practice structure and retention on a simulated task—not evidence that practicing components alone prepares someone for every field condition.
For a learner, the practical implication is to consider both focused repetition and putting the components together. Separate practice can concentrate attention on a particular part of a task; a combined task can show whether the learner can coordinate those parts. The experiment does not establish that one sequence is best for all learners, machines or work assignments.
The two-week interval matters because it makes the result a retention finding, not just a measure of performance immediately after practice. It still does not show how long the advantage lasted beyond that test or whether the same pattern would appear on a real machine. A program should not promise that part-task practice guarantees better long-term field performance on the basis of this experiment.

Performance feedback and simulator design
Simulator features should not be mistaken for proof of training effectiveness. A 2023 excavator-simulator experiment found no evidence that a motion platform helped or hurt performance in that experiment. That result does not show that motion feedback is essential, nor does it prove it is useless in every setup or for every learner.
A 2017 Chalmers University of Technology paper describes development of a full-scale excavator training simulator and assignments intended to address safety, quality, economy and environmental sustainability. It helps illustrate the range of goals a curriculum may include, but it is not evidence that every simulator teaches those outcomes. Evaluate a simulator and its curriculum by the tasks and feedback it provides rather than by realism or hardware alone.
In other words, physical scale or a motion platform should not substitute for asking what instructional objectives the program has, how the learner receives feedback, and how progress is checked. A 2009 review of construction-equipment operator training simulators called for careful testing of both skill acquisition and transfer to real equipment. A convincing demonstration or realistic-looking interface is not the same as evidence that a skill carries over.
What does field training add?
Field training gives the learner practice and assessment on an actual excavator. This matters because the direct transfer study tested both the simulator-trained and real-machine-trained groups on a common real excavator. The simulator group’s performance on that test supports a transfer claim for the studied task; it does not remove the need to see how a learner operates the machine used for the intended work.

Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →The available studies do not itemize a complete set of “field-only” skills, so it would overstate the evidence to claim that a particular checklist of abilities can never be addressed in simulation. The defensible practical point is narrower: a simulator result is not the same thing as an on-machine assessment. A learner who will operate an actual excavator needs supervised practice and evaluation on actual equipment, with attention to the assigned work and applicable workplace requirements.
Field practice also lets an instructor evaluate the learner in the operating context that matters for the job. The evidence provided here does not measure how particular site conditions affect learning or define a universal field-training syllabus. Training decisions should therefore be made around the equipment, task, learner and work requirements rather than assuming that a simulator study covers every operating situation.
That distinction is useful when interpreting course completion. Simulator completion can show that a learner has practiced the assigned simulated exercises; it cannot, on its own, demonstrate performance on an actual machine. Conversely, the cited studies do not show that every simulator exercise is ineffective or that all skill development must begin in the field. The practical question is whether the learner has been appropriately prepared and then evaluated on the equipment and work they are expected to handle.

Can simulator training teach you to operate a real excavator?
It can help teach skills that transfer to a real excavator on a defined task, but the evidence is limited. The strongest direct comparison is a 2016 study at the John Deere and Company Demo Site in Coal Valley, Illinois. Participants practiced a trench-and-load task either on a simulator or on a real hydraulic excavator; both groups were tested on a common real machine. Simulator-trained participants improved across daily sessions and reached the real-machine group’s performance level after 10 hours of operating practice. The study was published online by the American Society of Civil Engineers on May 24, 2016.
The USDA Forest Service’s 2024 review describes the experiment as four days totaling 10 operating hours. It says the simulator group learned more slowly at first, then caught up by the end. The review also notes that the directly comparative study it found used construction equipment rather than forestry equipment. Read the USDA Forest Service review.
Those details define what the result can support: in that experiment, for the studied trench-and-load task and training period, simulator-trained participants reached the comparison group’s performance level on a real-machine test. It does not establish that all trainees will reach that level, that all excavator tasks transfer equally well, or that simulator practice alone makes a learner ready for unsupervised work. The review’s qualification about construction equipment also cautions against applying the result directly to forestry equipment.
The 10 hours are not a universal threshold. They describe the operating-practice duration associated with the result in this particular comparison, conducted over four days. The study does not tell an employer to schedule every trainee for exactly 10 simulator hours, nor does it say that 10 hours is sufficient for every person, attachment, task, or operating environment. Treat it as a bounded example of transfer, not a training prescription.
How should simulator and field practice fit together?
The findings are consistent with a blended approach: use simulation to introduce or rehearse component skills, then use supervised practice and assessment on the actual machine. This is a practical interpretation of limited evidence, not a tested formula. The studies do not identify an optimal number or proportion of simulator hours relative to field hours.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- Match practice to the work. Identify the excavator, task and operating requirements the learner is expected to handle. The cited experiments address defined tasks, so do not treat their results as covering unrelated work.
- Use simulation for purposeful practice. Choose exercises that correspond to the controls and task components the learner needs to practice. Where useful, consider both component exercises and a combined task; the part-task retention result does not make that structure universally superior.
- Move to supervised machine practice. Have the learner operate the actual equipment under appropriate supervision. The cited transfer study assessed participants on a common real excavator, providing a reason to verify performance on real equipment rather than infer it from simulator performance.
- Assess the assigned work, not just practice time. Judge whether the learner can perform the relevant task safely and effectively on the machine and in the context of the work. Do not use 10 simulator hours as a pass mark: that was the duration associated with a result in one experiment, not a certification threshold or general recommendation.
- Adjust the mix to the learner and job. Instructor judgment, learner progress, machine and task all matter. Workplace requirements and the applicable jurisdiction may also determine what training or evaluation is needed.
This sequence avoids two unsupported assumptions: that simulator time is automatically equivalent to field time, and that every learner needs a fixed, evidence-based number of hours in either setting. The available evidence supports transfer on a particular task, not a one-size-fits-all training plan.
A practical way to use the sequence is to make each stage answer a different question. Simulator exercises can help the learner rehearse specified controls or task components. A combined exercise can reveal whether components are coordinated in the simulated task. Supervised field practice then checks performance on the real machine, and an assessment can determine whether the learner is ready for the assigned work or needs more instruction. The cited studies do not prescribe this exact sequence, but it is consistent with their limited transfer findings and avoids treating practice time alone as proof of competence.

There is also no basis here for a price comparison or a claim that one format is always cheaper. Simulator practice avoids using a working excavator during that practice, but the cited studies did not calculate purchase, rental, instructor, setup, or operating costs. A provider or employer would need to compare those costs for its own program rather than relying on a general savings estimate.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What do the studies say about retention and practice schedules?
Transfer and retention are different questions. Transfer asks whether practice in one setting helps performance in another; retention asks whether performance persists after an interval. The 2016 comparison addressed transfer to a real excavator on a specific task. The 2013 part-task experiment assessed retention on a simulated task after two weeks. Neither result answers every question about long-term readiness on a jobsite.
A separate 2013 virtual training-system study compared blocked and mixed practice schedules for construction-equipment operator skills and reported similar benefits from the two schedules. Its authors noted that task complexity can make training effects difficult to isolate. The study appeared in Automation in Construction. This finding does not establish that blocked and mixed practice are equivalent for every excavator task, or that schedule choice does not matter in a different curriculum.
These studies answer narrower questions than “Which training method is best?” They suggest that task design and practice structure are worth considering, while leaving open how schedules should be chosen for different learners and operating demands. A training plan should not claim a general retention or transfer advantage beyond what its specific evidence supports.
For a reader comparing course descriptions, “mixed practice” and “blocked practice” are not guarantees of quality. The virtual-system study reports similar benefits for the schedules it tested, while also warning that complex tasks can make effects hard to isolate. Ask what tasks are scheduled, how the learner gets feedback, and what happens when the learner is ready to move from practice to the actual machine. The studies do not identify one schedule as the required choice.
What does the evidence not establish?
A 2009 review of construction-equipment operator training simulators called for careful experimentation to demonstrate both successful skill acquisition and transfer to real equipment. The review is indexed by the Transportation Research Board’s TRID database. Its caution remains relevant when interpreting simulator claims: realism, feature lists and a learner’s successful completion of an exercise do not by themselves prove that skills have transferred to actual work.
- No universal hour threshold: The 10-hour finding belongs to one experiment, one defined task and one comparison. It is not a standard for training, certification or independent operation.
- No universal simulator-versus-field ratio: The cited studies do not specify the ideal allocation of practice time between settings.
- No all-task guarantee: A result on trench-and-load practice does not establish transfer to every excavator task, machine or operating context.
- No blanket conclusion about simulator hardware: One motion-feedback experiment does not settle the value of motion platforms generally.
- No quantified savings or general safety effect: The cited evidence supports practice and a limited transfer result; it does not quantify cost savings or prove a universal safety benefit from simulator use.
Keeping these boundaries clear makes the comparison more useful: evidence of transfer is meaningful, but it is not a substitute for evaluating the specific learner on the specific work they are expected to perform.

The studies also do not establish a universal certification, course-completion, or employer-approval pathway for excavator operators. A training program may set its own curriculum and assessment, but the experimental findings do not define what credentials a particular job requires. Confirm applicable workplace and jurisdictional requirements separately instead of treating a study duration or simulator score as a credential.
Does OSHA require simulator or field training for excavator operators?
Do not use OSHA 29 CFR 1926.1427 as an excavator-specific rule. It is a construction regulation covering training, certification and evaluation for covered crane operators. For the crane categories within its scope, OSHA says: “The employer must provide each operator-in-training with sufficient training, through a combination of formal and practical instruction, to ensure that the operator-in-training develops the skills, knowledge, and ability to recognize and avert risk necessary to operate the equipment safely for assigned work.” The provision also requires an operator-in-training to be continuously monitored on site while operating equipment under that rule. See OSHA’s text of 29 CFR 1926.1427.
That crane language should not be presented as an excavator training mandate. Before making a legal or compliance decision, verify the rules that apply to the actual equipment category, work and jurisdiction. Training evidence and regulatory requirements are separate questions: a simulator experiment does not establish what a particular employer or jurisdiction requires.

Can simulator training teach you to operate a real excavator?
It can help develop skills that transfer to a real excavator on a defined task. In a 2016 comparison, simulator-trained participants reached the real-machine group’s performance level after 10 hours of practice on a trench-and-load task, and both groups were tested on a common real machine. That is a result from one study, not proof that simulator-only training prepares every learner for every task.
Do you still need hands-on excavator training?
Yes, if the learner will operate an actual excavator, performance should be practiced and assessed on actual equipment under appropriate supervision. The available studies do not provide a complete list of field-only skills, but a simulator result is not the same as an on-machine assessment.
How many hours of simulator practice transfer to a real excavator?
There is no established general number. One study found transfer to the comparison group’s performance level after 10 operating hours on a specific trench-and-load task. The USDA Forest Service’s 2024 review describes those 10 hours as spread over four days and notes that the simulator group learned more slowly at first. Do not treat 10 hours as a standard, pass mark, or guarantee.
Is simulator training cheaper or safer than field training?
The cited studies do not quantify cost savings or establish a universal safety benefit. Simulation allows practice without operating a working excavator during that session, but costs and safety outcomes depend on the program and were not measured in the evidence discussed here.
Recommended Free Tools
Does OSHA require a simulator for excavator-operator training?
The cited OSHA provision, 29 CFR 1926.1427, covers training, certification and evaluation for covered crane operators; it is not an excavator-specific rule. Check the requirements that apply to the equipment, work and jurisdiction in question.
Are part-task drills better than practicing a complete task?
In one 2013 simulator experiment, a part-task group had higher productivity than a whole-task group on a retention test after two weeks. That result concerns a simulated task and does not prove part-task practice is best for every learner or that it replaces combined-task and field practice.
The Bottom Line
Bottom line: Simulator training can provide purposeful practice and has shown transfer to a real excavator for a defined trench-and-load task. The 10-hour result is one study’s finding, not a universal training target. Use simulator sessions to rehearse relevant tasks, then verify readiness through supervised practice and assessment on the actual machine. There is no established simulator-to-field hour ratio, general cost advantage, or blanket safety guarantee in the cited evidence.
