3.3 Drawbar
The tractor drawbar must be positioned at a certain length based on the operating speed of the mower to ensure proper driveline operation. 540 RPM mowers require the drawbar length measured from shaft end to hitch pin hole to be positioned at 14”.
Ensure the drawbar is rated to carry the tongue weight of the mower.
3.4 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership.
3.5 Power Take Off (PTO)
Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a
