assembled, adjusted and lubricated before use.
Illustrations to assist with the assembly process are
provided in “Standard Specifications” on page 2-1.
They show proper disc gang, wing stabilizer bracket, and
light mounting bracket spacing. Illustrations in this
section show proper assembly procedures. Remove
paint from grease fittings. Replace any grease fittings
that are damaged or missing. Be sure to return screws,
clips, etc., to their original locations.
To insure alignment of assemblies, leave the nuts loose
until completion of final assembly. Use lock washers or
flat washers as specified. Spread all cotter pins.
After completion of final assembly, tighten all nuts
evenly to prevent misalignment, distortion or binding.
Tighten all screws and nut s to the recommende d torques
shown in Table 2-1.

Assembly Instructions
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.
To prevent accidental lowering:
1. All hydraulically elevated equipment must be
locked out using the cylinder lockouts.
2. Lower equipment to the ground while
servicing or when it is idle.
Failure to take measures to prevent accidental
lowering may result in serious personal injury or
death.
Disc blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall o nto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Neve r pus h
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
Be sure to bleed the hydraulic system of all air in
lines after inst allation. Failure to bleed the system
of all air can result in improper machine
operation.
Incorrect adjustment of disc adjust rods will
cause permanent equipment damage.

WARNING
NOTE
NOTE
Assembly
Read all safety precautions at the front of the section
before attempting any of the following procedures.
1. Place the center frame assembly on stands
approximately 36” high. The assembly area should
be a large level area of sufficient size to
accommodate the disc when fully assembled.
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.
2. Attach the hitch weldment to the front of the center
frame using 1-1/8-7 x 7-1/2 hex head cap screws,
machine bushings, hitch mounting plates, and hex
lock nuts (See Figure 3-1.) Machine bushings are
provided to remove the slack on each side of the ball
joints and center the hitch. Use bushings as required.
ASSEMBLY INSTRUCTIONS
The hitch may be assembled in the upper or lower
position depending on matching tractor drawbar height.
See “Hitch Adjustment” on page 4-12 for proper
adjustment.
3. Move the tongue jack to the forward mounting tube
and rotate to parking position to support the front of
the hitch.
4. Insert a 3/4-10 x 7 hex head cap screw into the hose
holder tube on the right side of 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 br acket may pivot
freely in this joint.
5. Slide the hose holder bracket over the screw and
secure with another 3/4 prevailing torque flange nut.
6. 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.
7. 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.
8. Install hose holder clamp at rear of hitch with 1/2-13 x
11 hex head cap screws and hex lock nuts.
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.
