LJ60/72 02-02 Operation Section 4-7
OPERATION
© 2004 Alamo Group Inc.
2.6 Power Take Off (PTO)
Depending on the equipped gearbox, LJ60/72 cutters are designed to operate at either 540 or 1000 rpm. Most
tractors operate at either 540, or a combination of 540 and 1000 rpm PTO speeds. The speed of the tractor PTO
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” shaft. NOTE: The
LJ60/72 will not operate on tractors equipped with a 1000 rpm 20-spline, 1-3/4” shaft. Refer to the tractor
owner’s manual for instructions to change PTO speeds on models that operate at more than one speed.
3. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the cutter and tractor operator
manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete
explanation.
WARNING!
Do Not mount or dismount the Tractor while the Tractor is moving.
The Tractor engine must be turned off, the Tractor transmission in
park or neutral with the parking brake set, and all moving Tractor
and Implement parts at a complete stop before boarding or exiting
the Tractor.
WARNING!
Never use a PTO shaft adapter to connect a Mower to a Tractor which operate at different speeds.
The Mower must be operated by the Tractor at its rated speed (depending on mower either 540 or
1000 rpm) to provide a specfic blade speed for efficient and safe mowing. Attaching a non-conforming
tractor PTO shaft to an Implement driveline using a PTO shaft adapter will result in the Implement
operating at a greatly increased or reduced speed. Use of a PTO shaft apapter will also change the
working length of the driveline and expose unshielded driveline areas. Serious bodily injury and/or
equipment failure can result from combining non-conforming Tractor and Implement speeds with the
use of an adapter. Consult an authorized dealer for technical assistance if the Tractor and Mower
are designed to operate at different speeds.
