Tractor Hook-up
!
DANGER
To avoid serious injury or death:
A crushing hazard exists while hooking-up and unhooking
implement. Keep people and animals away while backing-up
to implement or pulling away from implement. Do not operate
hydraulic controls while a person or animal is directly behind
the power machine or near the implement.
!
WARNING
To avoid serious injury or death:
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
•
Jack must be installed on the hitch and jack attachment pin
must be fully inserted and secured before working on or
around an implement not hooked to the tractor drawbar.
1.
Make certain park jack (#6) is properly attached to
implement hitch mount (#5) and secured with detent
pin (#7).
2. Pivot clevis hitch (#3) up horizontally and support in
this position with wire retaining pin (#4).
3. Start tractor and raise lower 3-point arms fully up.
Back tractor within close proximity of clevis (#3).
4. Raise or lower park jack (#6) to align clevis (#3) with
tractor drawbar. Drawbar should fit between lower
and upper plates of clevis.
5. Back tractor up to implement hitch clevis (#3) until
holes in drawbar and clevis are aligned.
6. Remove wire retaining pin (#4) and store in a safe
place for future use.
7.
Insert 1 1/4" flat washers (#9 & #10) equally above
and below tractor drawbar until both spaces between
drawbar and clevis plates are filled. This will reduce
drawbar wear.
8. Insert 1 1/4" -7 x 6 1/2" GR5 hex bolt (#2) through
bottom clevis hole, 1 1/4" washers (#9), tractor
drawbar, remaining 1 1/4" washers (#10) and out
through upper clevis hole. Secure hex bolt with hex
nut (#13) and jam nut (#14). Tighten hex nut snugly to
remove all play and then back nut one-quarter turn.
Tighten Jam nut (#14) tight against hex nut (#13).
9. Lower park jack (#6) until implement weight is
removed from park jack. Rotate park jack
counterclockwise 90 degrees and reinsert detent
pin (#7) for storage.
10. Attach hitch safety chain (#1) to tractor. Adjust chain
length to remove all slack except what is necessary
to permit turning. Lock chain hook securely to the
safety chain.
11. Pin tractor drawbar in fixed center position.
