A Few Hints On How To Avoid Power
Hop...
- Make sure your tractor has sufficient weight (ballast) to transmit the power to the ground.
- Make sure the weight of your tractor is distributed correctly between front and rear axles.
- Make sure your tires are inflated to the correct pressures to carry the load, taking into account additional weights of implements, tanks and other loads.
What is power hop?
Power hop is a vertical jumping
of a 4WD or MFWA tractor under load.
It begins with a difference in traction between front & rear
tires, causing energy to build up in the tires & drivetrain.
When the tires finally break traction, recoil energy is released
suddenly, causing the machine to jump. Once Power hop begins,
it tends to continue under its own momentum.
When does power hop
occur?
Power hop can affect any make or model of 4WD or MFWA tractor. It
occurs under heavy drawbar load, most commonly with towed implements.
Typically the ground is dry and very firm underneath, with loose
soil on top.
Power hop tendency and intensity increase as power input increases.
Power hop can occur with bias or radial tires, but... It is most
prevalent with radial tires because they have significantly more
traction than bias tires.
But, power hop can be controlled!
What causes Power hop?
- Not enough tractor weight for tractor horsepower
- Incorrect weight distribution between front and rear axles
- Incorrect tire pressures
- Improper drawbar position
- Tires too small for tractor horsepower
Following the Rules To Obtain Optimum
Tire Performance Will Solve Most Power Hop Problems.
