Section 2 Assembly Instructions & Set-Up
Read and understand the owner’s manual for your All
Seeds Hitch. A basic understanding of how the hitch
works will aid in the assembly and setup of your hitch.
The following information is general in nature and was
written to aid the operator in preparation of the tractor
and hitch for use, and to provide general operating pro-
cedures. The operator’s experience, familiarity with the
machine and the following information should combine
for efficient hitch operation and good working habits.
Having all the parts and equipment readily at hand will
speed up your assembly task.
Assembling The All Seeds Hitch
For the following assembly instructions refer to Figure 2-2.
1. Remove the transport tire, hub, and spindle assem-
blies (#1) which are banded to the hitch and slide the
spindles into the outer spindle tubes of the transport
rockshaft. Secure the spindles in place with the 1/2"
x 4 3/4" long bolts (#2) and the 1/2" lock nuts (#14).
Cut the bands that hold the tongue and tongue cyl-
inder to the hitch and swing it into position and pin
the cylinder to the cylinder lug on the hitch. Swing
the tongue links into position and bolt them to the
ears on the front tongue.
2. Center the coulter tool bar assembly (#3) under the
hitch (#4) and fasten to upper coulter tool bar sup-
port with the 5/8” x 6” long bolts (#5), 5/8” flat wash-
ers (#6), 5/8” lock washers (#7), and 5/8" nuts (#8).
It is critical that the coulters are centered under the
All Seeds Hitch to insure proper tracking with the
drill. Use extra care when assembling the coulter
tool bar assembly to the hitch. The coulter tool bar
assemblies should have a coulter blade gap cen-
tered on the center line of the hitch.
3. Assemble the spring hose loop (#9) on the hydraulic
tongue (#10) with a 1/2" x 1" long bolt (#11), two 1/2"
flat washers (#12), and a 1/2" lock washer (#13).
The spring hose loop bolts to a coupler nut welded
near the front of the hydraulic tongue.
4. Refer to Fertilizer Option Manual (GP 148-152M) for
assembly of optional Liquid Fertilizer Attachments.
5. Refer to Coulter Command Option Manual (GP 148-

263M) for assembly of optional Coulter Depth Control
Attachments.
Tractor Drawbar Hookup
For the following assembly instructions refer to Figure 2-1.
1. Place hitch weldment (#1) over the ball swivel of the
front hydraulic tongue and hold in place by inserting
the inner spacer tube weldment (#2) through the large
hole in the hitch clevis and ball swivel.
2. Back tractor up to the machine and bolt hitch weld-
ment assembly (#1) & (#2) to tractor drawbar large pin
hole using the 1" x 10" long bolt (#3), large flat washer
(#4), 1" lock washer (#5), and 1" nut (#6). Use 3/4" x
9" long bolt (#7) to bolt the hitch weldment through its
slotted hole and into the secondary hole of the tractor
drawbar. Install a 3/4" flat washer (#8) next to the top
slotted hole and fasten with a 3/4" lock washer (#9)
and 3/4" nut (#10). Tighten both bolts.
