OPERATION
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”
clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a
minimum profile engagement of 12” must be maintained.

8. PUMP & SPEED INCREASER ATTACHMENT

To attach the Speed Increaser and Pump to the
tractor, use the following procedure:
1. 1. Attach the Speed Increaser Mount Plate to
the tractor loosely. Refer to the installation
drawing, supplied in the packing box, for
specific instructions.
2. Grease the tractor PTO shaft and slide the
Speed Increaser on. Install the 1/2" bolts and
bushings between the Speed Increaser and
Mount Plate. Do not tighten bolts at this time.
3. With the tractor in idle and the PTO engaged,
alternate tightening the Mount Plate bolts
following an "X" pattern until they have all been
tightened. Refer to Torque Chart for proper
torque.
4. Grease the inside and outside of the Splined
Adapter Bushing an d insert it into the Speed

9. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of mower and tractor must be performed. This
includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and
functional, and performing needed repairs. Do not operate the mower and tractor if the pre-operation
inspection reveals any condition affecting safe operation. Perform repairs and replacement of damaged and
missing parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable
down time and repair costs can be avoided.
