15 Preparation and Setup
4. Hitch the sprayer to the tractor using a hitch pin of
adequate strength (minimum 1 inch diameter). You
must also install a retaining clip on the hitch pin to
prevent it from coming out and causing a chemical
spill. Retract the jack until the weight is transferred to
the hitch.
5. Recheck to see that the frame is sloping downward
in the front with dimension “A" being approximately
1 1/2 inches greater than dimension “B”.
6. Your Sprayer comes equipped with a hitch safety
chain. The safety chain should be securely attached
to the sprayer hitch and the tractor drawbar support
whenever towing or spraying.
Refer to Figure 4
7. Unpin the tongue jack, and pin it in the transport po-
sition.
Note: When hitching the sprayer to a different tractor,
check for a difference in drawbar heights. If the heights
are different, the hitch height must be readjusted accord-
ingly.

Refer to Figure 1
The Great Plains Tandem Axle Sprayer is equipped with
either a clevis style hitch, or a single tang hitch.
Refer to Figure 2
1. Park the sprayer in an open, flat area with the jack in
the park position. Using a tape measure, check the
distance from the front under side of the frame to the
ground and the back under side of the frame to the
ground. Adjust the jack so that dimension "A" is
1 1/2 inches greater than dimension "B". The goal is
to have the solution drain into the sump of the tank
so there is no excess solution in the tank when
drained.
2. Back the tractor draw bar up to the sprayer hitch to
determine the amount of adjustment needed.
Refer to Figure 3
3. The mounting holes in the hitch have three positions
that it can be located. Move the sprayer hitch height
to the height of your tractor’s drawbar and bolt the
hitch onto the sprayer making sure to torque the
bolts to the correct specification on the “Torque Val-
ues Chart” on page 62. The single tang hitch has
the same height adjustment as the clevis hitch.
