6250 Disc Frame and Hitch
Assembly
IMPORTANT
Read all safety precautions at the front of the section
before attempting any of the following procedures.

WARNING
1. Attach the hitch weldment to the front of the center
frame using 1-1/2-6 x 11 hex head cap screws, 1-1/2
thrust washers, split lock washer, hitch mounting
plates, and hex nuts
(See Figure 3-8.)
NOTE
The hitch may be assembled in the upper or lower
position depending on matching tractor drawbar height.
See “Hitch Adjustment” on page 4-11 for proper
adjustment.
2. Move the tongue jack to the forward mounting tube
and rotate to parking position to support the front of
the hitch.
3. Insert a 3/4-10 x 10-1/2 hex head cap screw into the
hose holder tube on the hitch from the bottom side so
the threads point upward. Hold in place with a 3/4
prevailing torque flange nut with the flange pointing
upward as well. Do not tighten this cap screw, so the
hose holder bracket may pivot freely in this joint.
4. Slide the hose holder bracket over the screw and
secure with another 3/4 prevailing torque flange nut.
5. Install a 3/8-16 x 3-1/2 all-thread screw in the front of
the hose holder bracket and secure with a 3/8-16 hex
nut.
6. Slide the hose holder clamp over the 3/8” screw and
loosely start the wing nut on top of the clamp.
Hydraulic hoses will be routed through the clamp
after assembly.
NOTE
The clamp has two sides, so that extend hoses can be
located on one side and retract hoses can be located on
the other side for reference.
7. Install 1/2-13 x 11 hex head cap screws and hose
clamps until the hoses are routed through them.
8. Loosely install 1/2-13 x 12 hex head cap screws and
hose clamps until the hoses are routed through them.
Do not attempt to lift heavy parts (such as the
frame, disc gangs, rock shaft, and pull hitch)
manually. Use a hoist or a fork lift to move these
parts into position.
