Power hop is a condition where the tractor exhibits severe bounce and/or jump at field working speeds under 16 km/h (10 mph), and is associated with tractors pulling towed implements at medium to high draft loads in loose, dry soil on top of a firm base and/or when climbing hills.
Make the following adjustments to inflation pressures,
only
after following the performance guidelines (recommended weight split, correct ballast, and correct inflation pressures):
1.
Increase
front
tire pressure in 14 kPa (0.1 bar)
(2 psi) increments over the rated pressure until power hop is controlled.
Rear
tire inflation pressures should remain at rated pressures for the load.
IMPORTANT:
Front tire pressure should not exceed 41 kPa (0.4 bar) (6 psi) more
|
than the maximum rated inflation pressure shown on tire side wall.
2.
Remove any liquid ballast in rear tires and replace with rear cast weight equivalent, if power hop remains a problem.
3.
Install up to 75 percent liquid fill in front tires and remove an equivalent amount of front cast weight to maintain recommended weight split, if power hop remains a problem.
4.
If power hop remains a problem, see your John Deere Dealer.
NOTE:
Tire inflation pressures and ballasting may need to be changed when operating conditions change.
