SECTION 2 - OPERATION
2-105
ATTACHING 3-POINT EQUIPMENT
Before attaching equipment to your tractor:
• Be sure the guide blocks are positioned to “fit” the
equipment as outlined under the “Sway Blocks”
and “Guide Blocks, Spacers and Shims”
headings.
• Remove the swinging drawbar, if close-mounted
equipment is being attached.
IMPORTANT: Always set the position/draft sensitiv-
ity control knob in position control when attaching
equipment, transporting equipment, when no
equipment is attached or at any time when not
operating in draft control.
NOTE: See also “External 3-Point Hitch Controls” for
more details.
Most equipment can be attached to your tractor as
follows:
1. Position the tractor so that the lower link hitch
points are level with and slightly ahead of the
implement hitch pins.
2. Stop the engine and engage the parking brake.
3. Release the flexible link ends, and slip the ends
on the implement hitch pins. Secure with the linch
pins. Start the engine and slowly back the tractor
up until the flexible link ends lock in the operating
position. Stop the engine and engage the parking
brake.
IMPORTANT: Before transporting or operating
equipment, be sure that the link ends are locked in
the operating position.
4. Lengthen or shorten the top link, until the
implement mast pin can be inserted through the
mast and top link. Adjust the top link to the initial
724 mm (28.5″) setting.
5. Attach any remote equipment.
6. After attaching implement and before actual
operation check that:
• No interference occurs with tractor compo-
nents.
• Top link does not contact the PTO guard with
implement at its lowest position.
• PTO driveline (if equipped) is not overex-
tended, bottomed out or at an excessive
angle and driveline shield does not contact
PTO guard or drawbar.
IMPORTANT: Before operating PTO driven equip-
ment, check to make sure the driveline will not bottom
out or become disengaged. See “Attaching Equip-
ment to the PTO Shaft” heading in the “Independent
PTO” section for details.
IMPORTANT: When attaching mounted or semi-
mounted equipment to the 3-point linkage or when
attaching trailed equipment to the drawbar or hitch,
be sure that there is adequate clearance between the
implement and the tractor.
Check the clearances in the raised position by raising
the implement carefully using the lift control lever,
Figure 125, in position control. Check the swing
clearance by performing a series of left- and
right-hand turns with the tractor and implement
combination.
IMPLEMENT TO CAB CLEARANCE
CAUTION
Some mounted and semi-mounted equipment
may interfere with and damage the cab.
WARNING
You may be injured by broken glass or the cab
ROPS may be damaged if equipment interferes
with the cab.
To prevent cab damage, proceed as follows:
1. Attach the equipment as outlined previously.
2. Check for adequate clearance by slowly raising
the equipment with the lift control lever in
POSITION CONTROL. If the equipment clears
the cab by 100 mm (4″) or more when fully raised,
proceed to operate the equipment. If any part of
the equipment comes closer than 100 mm (4″) to
the cab, do the following:
Adjust the 3-point hitch height limit control knob,
Figure 126, to limit upward movement so there is
a minimum of 100 mm (4″) clearance between
the cab and the implement.
IMPORTANT: The height limit must be adjusted to
limit hitch height when the RAISE/WORK switch is
activated.
REMOVING EQUIPMENT
When removing equipment, the procedure is the
reverse of attaching. The information listed below will
make disconnecting easier and safer.
• Always park the equipment on a level, firm
surface.
• Support equipment so that it will not tip or fall
when detached from the tractor.
• Always relieve all hydraulic pressure in remote
cylinders by selecting the float position before
disconnecting.
