Drawbar-Pull Type Mower; Power Take Off (Pto) - RHINO TW30 Series Operator's Manual

2.6 Drawbar-Pull Type Mower

For equipment operating at 540 RPM, the tractor
drawbar must be positioned at a 14" distance from the
hitch point to the PTO shaft end for proper operation and
minimal wear to the driveline. 1000 RPM Models require
16 inch drawbar length.
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.

2.7 Power Take Off (PTO)

This mower is designed to operate at a PTO speed of 540 for the TW35 and TW36. 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.
Note: Only the TW37 mower can be ordered to operate on tractors equipped with a 1000 RPM 21-spline
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. OPS-R- 0066_E
