3. Secure the two legs with six (three per side) 1/2” x 1-3/4” carriage bolts, flats washers, locks washers,
and hex nuts. The six holes will be already punched out of the baler frame and will line up with the
saddle legs. Make sure the bolt head is in the chamber.
4. Install the tank saddle (001-6707N) on top of the saddle legs. Figure 3
5. Secure the tank saddle to the saddle legs using eight (four per side) 1/2" x 1-3/4” carriage bolts, flat
washers, lock washers, and hex nuts. Use the outside set of holes for four foot wide balers and the
inside set of holes for three foot wide balers. Figure 3
6. Make sure the carriage bolt heads are on top of the saddle and the bolt points towards the bale
chamber.

7. Installation of the Controls
Route the wire to the starter solenoid on all 12v tractors. Connect the green lead marked +to the hot terminal
on the starter. Connect the black lead to a good ground. Do not reverse the leads. Be sure to use a
voltmeter to verify that you do have 12 volts running to the box.
Note: For tractors with 24v starters, connect the power leads to the tractor’s right hand battery. Do not
connect the leads to the starter. Connect the lead marked + to the positive battery terminal and the lead
marked- to the negative on the battery. Wiring connections to the battery normally results in corrosion;
terminal coating is recommended.
Caution: Do not run a pump or use an electronic control box directly off a battery charger. For stationary use,
the applicator can be connected to a new battery and the battery connected to a charger.
