Ground speed

Wheel traction

Tire pressure in the traction wheels is critical for maximum traction capability. Over-inflated tire pressure can cause spinning and tearing out of the turf in adverse conditions. if lowering the tire pressure does not correct or stop a spinning condition, adding liquid to the tires may be required.

Avoid quick acceleration while operating mowing equipment because a spinning tire can seriously damage the turf. Try to maintain a constant speed while going through turns and climbing hills to avoid a spin out which would damage the turf.

Engine RPM

The correct engine speed is important for the effective performance of a rotary cutting unit. Most professional mowing equipment is designed to operate at full engine RPM. All engine RPM information is contained in the owner's manual for each product. The engine speed should be checked with a tachometer periodically.

Ground Speed

There are three basic problem areas resulting from too fast a ground speed. It is unsafe, damaging to the equipment and will result in a poor quality of cut.

The ground speed of a rotary mower must be limited to a point that the blade can cut and discharge the grass effectively while maintaining a good quality of cut. If the cutting unit is becoming overloaded, the ground speed must be lowered and/or the cutting width should be reduced so the engine can regain its normal operating speed.
