Drawbar - Pull Type Mower; Front End Weight; Power Take Off (Pto) - Bush Hog 3510R Operator's Manual

2.5 Drawbar - Pull Type Mower

For pull type mowers (540 and 1000 RPM)
equipped with an equal-angle driveline, the tractor
drawbar must be positioned as follows:
540 RPM at 14" Drawbar
1000 RPM, 1-3/8 at 16" Drawbar
1000 RPM, 1-3/4 at 20" Drawbar

2.6 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. OPS-U- 0005

2.7 Power Take Off (PTO)

This mower is designed to operate at a PTO speed of 540. 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 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft or a 1-3/4" 20-spline
shaft.
If operating an older model tractor where the tractor's transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized
tractor dealer can provide the over-running clutch and its installation if needed. OPS-R- 0066_C
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
DANGER
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
