Benefits of Owning a
Joe Built Motorized Wheelbarrow



When using foreign labor, you loose every cent you pay. Sure you get the job finished, but can you write the expense of labor cost from your taxes? Unfortunately, you cannot.  Your money is gone, you can’t expense the workers either, and then to top it off, you have to pay government taxes on the money you paid your workers!

The new and improved USMP Two Cycle gas engine driven Joe Built Wheelbarrow is tax deductible. You can also depreciate the motorized wheelbarrow over a span of one to three years.

For example, at a rate of $10.00 an hour it would take 6 times the man power to move what one man can move with the Joe Built Wheelbarrow per load. That is $60 an hour or $480 a day vs. $10.00 an hour or $80.00 a day. With the expense of 6 days work, the Joe Built is paid for; your labor costs are not recoverable.

Another great benefit…our Joe Built Wheelbarrow is almost half the cost of a comparable competitor’s product.  Also, have you checked the latest on the job statistics related to personal injuries caused by manual wheelbarrows?  Insurance rates have tripled in the last 10 years!  The Joe Built can eliminate worker injury and the associated costs.


Joe Built was designed to move 1,200 pound loads on almost any terrain, over almost any distance.  Do you have to move the load uphill? No problem with our two-cycle gas engine powered Joe Built!!  The Joe Built Wheelbarrow has a heavy duty 3 speed forward and a single speed reverse, Peerless Tecumseh Transaxle. Our Powered Wheelbarrow can climb and descend a 30 degree incline with no effort. Try any of these scenarios with a standard wheelbarrow and you will soon find yourself struggling to finish the job.

A standard wheelbarrow can carry about 200 pounds and requires skill and strength to maintain the load from tipping. Our patented design uses two large drive-wheels in the front and two large casters in the back to stabilize the load which can prevent premature dumping of stone, dirt, sod or concrete.

A very small individual can operate the Joe Built Wheelbarrow with a full load.  If you have an employee who can walk and chew gum, they should be able to handle the Joe Built Powered Wheelbarrow.


At a weight of only 280 pounds, our motorized Joe Built can easily be loaded into the back of a pick-up truck, step van, or SUV.

Our unique design gives our Powered Wheelbarrow much more mobility than other models.  It is mobile enough to fit through a standard doorway with the narrow tire option. It can also be used in restrictive areas where ATVs and small tractors can not fit or operate.


United States Motor Power is the manufacturer of the US820 Engine used by the US Marines for its unmanned aircraft. The aircraft, with a wing span of 25 ft., can maintain speeds of 175 MPH. This is the same motor used for the Joe Built. This is why US Motor Power will guarantee your Engine for 1 year when using our US2 Two-Cycle Oil, and the heavy duty frame for 3 years.


US Motor Power can customize the Joe Built Wheelbarrow to match your company color scheme.  We can even apply your company logo!

Joe Built has a selection of tires… the standard gel filled 18”x 8.50” wide “turf savor” type tire or the narrow lug 18”x4” “rough terrain” tire.  Both can be foam filled solid for complete puncture resistance.


  • Tax loss vs. Tax advantage
  • 6 to 1 ratio in man hours
  • Light and easy to maintain
  • Sky rocketing insurance rates
  • Can be transported in a small vehicle or trailer
  • One year guaranteed on engine when using recommended US2 Two-Cycle Oil and 3 years on the frame
  • Out performs and costs less than any competitor
  • Special Company Branding


If you work hard and smart and value time, money and your employees, you can’t afford not to own a Joe Built Wheelbarrow.

Please read the following information if you or your company intends to move large amounts of material and have not yet decided to purchase a Joe Built Powered Wheelbarrow.



Strength Testing for Employees: 

A Means of Reducing Injuries Caused by Overexertion

Gene Carmean, MPA


The need for physical testing for workers in manual materials handling jobs has been recognized by occupational health professionals, risk managers, and ergonomists increasingly over the past few years.  Risk managers have an interest in job safety and reducing workers' compensation costs.  Physicians and occupational health nurses seek to reduce unnecessary injuries and find ways to better predict in advance those most likely to become injured while ergonomists seek to redesign jobs to better match the work to the worker.

Back Injuries: A Continuing Problem

According to the National Academy of Sciences (NAS, 2001) study on musculoskeletal disorders and work, back injuries account for over one million workers losing time from work each year.  NAS conservatively estimates that back injuries cost employers approximately $50 billion dollars each year.  According to this study, the most frequent risk factor associated with back injuries was "lifting and/or carrying loads."  Other risk factors identified included bending and twisting and whole body vibration.  However, no risk factor came close to the importance of lifting and carrying loads.  Injuries occur when there is a mismatch between the worker and the work.  Workers without sufficient strength to perform their job tasks incur injuries of overexertion.

Reducing Injuries Caused by Overexertion

Since overexertion injuries account for a significant number of all work-related back injuries to employees, it makes sense to reduce the probability of their occurrence.  Hiring workers with the adequate strength to perform the job can reduce these injuries.  One way to determine if a potential employee has the ability to perform the job is by administering a strength test.  Approaches to strength testing must meet two goals:

  1. Include a valid and legally defensible job analysis of the essential, frequently performed, and physically demanding tasks associated with the occupation.
  2. Ensure that the physical ability test is job-related, valid, and reliable that can confidently be used in the selection of individuals for physically demanding jobs. 

Experience with the model described below has resulted in the preplacement testing of more than 10,000 job applicants in California alone.

Strength Tests

Strength tests must be chosen on the basis of safety, reliability, and validity.  Ability tests are safer than job simulation tests because it is preferable to determine how much weight an applicant can lift rather than asking the applicant to lift a heavy weight.  If the applicant does not have the necessary strength to lift the weight an injury may occur during the test.

Valid strength tests should not be confused with Functional Capacity Evaluations (FCE).  FCEs typically involve multiple measurements of various physical dimensions including some assessments of strength and flexibility.  Periodic measurements using the same FCE can document changes in a patient's functional status over time.  However, FCEs typically suffer from the fact that they are basically measures of function with little or no evidence linking them to successful performance on a particular job.  In a comprehensive review of several widely used FCEs, Innes and Straker, (2000), found that "most work-related assessments have limited evidence of validity" and none had sufficient psychometric evidence to support an employment screening decision.  Because employers have legal responsibilities to not discriminate against either females or persons with disabilities, tests such as FCEs are unacceptable choices for physically screening workers prior to placement.  Strength tests must be designed to ensure that the ability test (selection device) is empirically demonstrated to be related to the job.

Preventing Lifting and Overexertion Injuries

To be able to lift properly to avoid injuries.

Trainer's Note:

Problems can arise from overexertion. On a flip chart list guidelines and suggestions for proper handling. Describe jobs that might result in overexertion. Ask a worker to demonstrate appropriate lifting techniques. Cover some practical tips to avoid overexertion.


Approximately 25 percent of workplace injuries in Ohio result from lifting, pulling or pushing objects. The part of the body most often injured is the back.

Material Handling - Think Before Lifting

  • Have a handling plan that avoids slippery hazards and includes a destination.
  • Test the load to ensure that it can be safely carried.
  • Know the limits! If the load is too heavy, awkward or bulky to carry alone, get help.
  • Use machinery or equipment, such as pushcarts, hand truck, wheelbarrow, forklift or hoist.
  • Do not overlook the use of levers, incline planes or rollers to move loads.

Serious back injuries occur because of improper lifting techniques. Some common improper lifting techniques people often use include:

  • Bending from the waist to pick up objects.
  • Lifting boxes above the chest.
  • Twisting the body to carry or lift a heavy box or object.
  • Lifting objects when in poor physical shape.

Guidelines for safe lifting:

  • Get a good grip. Grasp the load firmly. Use gloves if they allow for a better grip.
  • Get a good footing. Center body weight to provide a powerful line of thrust and good balance.
  • Keep it close. Grasp the load firmly and lift towards the belt buckle. Hold the load close to the body to avoid putting pressure on the back.
  • Lift smoothly. Raise, carry and lower the load smoothly. Never jerk a load.
  • Avoid twisting. If turning is required while lifting or carrying a load, turn the feet and body instead of twisting the back.
  • Push. Push rather than pull the load.

Review the Following Points

  • Approximately 25 percent of work related injuries in Ohio result from overexertion, mainly from lifting.
  • Think and plan before lifting.
  • Push rather than pull the load.
  • Use mechanical means whenever possible.
  • Avoid twisting when lifting or setting down a load. Turn the body instead of twisting the back.
