IMPORTANT: The PTO shaft yokes must be exactly
in line with each other when outer PTO is installed
on splined shaft. Remove sleeve and change yoke
position if alignment is not correct. Misalignment of
the two yokes will shorten life of PTO shaft assem ­
bly and cause unnecessary vibration when cutting
unit is operated.
8. Line up holes in yoke and input shaft of gear case.
Slide yoke onto shaft and secure parts together with roll
pin, capscrews and nuts.
9. Mount PTO shield over input shaft and onto gear case
mounting plate with two self tapping screws.
10. Attach three (3) lift chains to lift arm and cutting unit
with six (6) shackles, shackle pins and cotter pins.
Adjust chain length so that the front of the deck raises
level (side to side). When main lift cylinder is fully
extended the left push arm should be just below the
frame stop (1/16 to 3/8 inch). Half chain link adjustments
can be made by switching mounting holes in push arm
brackets. Tie up extra chain links if additional length may
be needed in the future.
IMPORTANT: Improper chain adjustment could re ­
sult in main deck lift arm damage if deck contacts
traction unit.
NOTE: As starting points use the following settings:
Right front chain – 10 links, lower bracket hole.
Left front chain – 14 links, lower hole
Rear chain – 10 links, upper and front holes
11. Adjust length of rear chain so rear caster wheels are
as far as possible from the ground but carrier frame does
not contact right push arm when deck is lifted.
CAUTION
Improper chain ad ustment may result in the j
deck contacting the traction pedal and forc ­
ing it into reverse.
12. To check adjustment, stay in the driver's seat, raise
the deck all the way and turn the key OFF. Set the
parking brake and then walk to the front of the traction
unit to see if the deck is contacting the linkage.
13. Connect ends of tension spring between fourth link
of rear chain and eye of cotter pin that holds cylinder pin
in place.
Repairs
1. PTO shaft yokes in phase
2. Roll pin
3. Gear case input shaft
