Front End Weight; Power Take Off (Pto) - Schulte FX-107 Operator's Manual

If attaching the mower tongue clevis to a 3-point hitch drawbar supported by the lower lift arms, the attaching
point must be extended past the main bar to allow for turning without binding the clevis and bar. Lift arm
stabilizers must be used with this type of drawbar to prevent the mower from swaying from side to side.

3.6 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

3.7 Power Take Off (PTO)

FX-107 mowers are designed to operate at a PTO speed of 540 RPM. Most tractors operate at either 540, or a
combination of 540 and 1000 RPM PTO speeds. The tractor PTO operating speed can be determined by the
number of splines on the PTO output shaft. Those operating at 540 RPM will have a 6-spline 1-3/8" diameter
shaft and those operating at 1000 RPM will have a 21-spline, 1-3/8" diameter or 20-spline, 1-3/4" diameter
shaft. Refer to the tractor owner's manual for instructions to change PTO speeds on models that operate at
more than one speed.
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.
