SECTION 2 - OPERATION

LINKAGE CATEGORY CONVERSION
Tractors are equipped with Category III linkage.
To convert from Category III to Category II, bushings
may be inserted into the top link and lower link
implement connections. The guide blocks and
spacers must be repositioned, as previously
described.
QUICK HITCH
The quick hitch allows fast, easy hitching and
unhitching of implements. The hitch fits implements
with ASAE category III hitches. Do not use the hitch
with implements which have offset cross-shafts such
as may be found on mounted moldboard plows with
in-furrow hitches.
Installation and Removal
1. Place the quick hitch, 1, at rear of the tractor and
install on the lower links using the lower link pins,
2, and retaining bolts.
Torque the retaining bolts to 115 N·m (85 ft.-lbs.).
2. Tilt the hitch upright and secure the upper link
with the top link pin, 3, and retaining bolt.
Torque the bolt to 115 N·m (85 ft.-lbs.).
3. Reverse the procedure to remove the quick hitch.
Hitching
1. Position the latch handles, 4, down as shown.
The latch handles must be down for the hitch to
latch.
2. Back the tractor to the implement making sure
that the lower hooks are below the implement
pins.
3. Raise the quick hitch until the pins engage the
hooks.
WARNING
Be certain that both latches fully engage the
implement hitch pins before transporting or
operating the implement.
4. Perform all checks listed under the “Attaching
3-Point Equipment” heading.
5. To unhitch equipment, position the equipment so
that it will not fall when unhitched and pull the
latch handles, 4, up to open the lift pin latches.
Lower the quick hitch until it disengages from the
implement. Remove any control connections
and slowly drive the tractor away.
