PREPARING THE WINDROWER

1. Be sure windrower is set up to match tractor
PTO speed. A quick way to check is to
measure the outside diameter of the driven
pulley (A):
9-1/2 inch (240 mm) - 540 rpm
12-1/2 inch (320 mm) - 1000 rpm
If not matched, and tractor PTO speed cannot
be varied, order a conversion kit from your
windrower dealer. (Kit includes front yoke,
decal and instructions.)
IMPORTANT: To avoid machine damage, follow
instructions provided in kit for removal of main
drive pulley. This procedure is also detailed under
"Removal of Main Drive Pulley" in Maintenance/
Service section.
2. Use correct hitch type: For tractors with clevis
type drawbar, windrower hitch is compatible
without modification. For tractors with straight
drawbar, an optional hitch plate (B) is available
to convert windrower hitch to clevis type.
To install:
- Remove bolt (C) securing hitch chain.
- Position plate (B) under hitch and replace bolt
(C) to secure hitch chain.
- Install bolt (D) from option kit and secure with
locknut.
3. With tractor drawbar adjusted to recommen-
dations listed under "Preparing the Tractor",
adjust the drive frame vertically at (E) so
telescoping driveline (F) is in straight line with
tractor PTO.
NOTE: The telescoping driveline (F) should
slide under hand pressure. Grease if required.
4. Install quick coupler tips matching the tractor to
be used on the two hydraulic hoses going to
the tractor.
