3.2.2 Hitching to Tractor
1. Adjust jack for tractor height.
2. Position tractor so hitch pin can be installed, and install pin. The hitch pin should be sized to prevent
excessive movement and should extend through all components of the hitch. The pin should be secured
with a hairpin clip or suitable device to prevent loss of pin.
3. Adjust jack so that jack stand is loose. Then place jackstand in the raised and locked position.
4. Attach PTO to tractor. Depress coupling and slide the coupling onto the spliced shaft. Make sure the
spring loaded safety catch is properly seated.
5. If required, install the safety chain. Check local regulations regarding safety chain requirements.
6. Clean off hydraulic hose ends and tractor couplings, then attach hoses to tractor.
7. Verify hydraulic hoses are hooked up in proper orientation.
3.2.3 Closed or Open Center Tractor hydraulics
Check specification on tractor to determine if it uses closed or open center hydraulics. Switch control valve on baler to
match tractor specification by rotating valve knob shown.
Step 1: Loosen jam nut.
Step 2: Turn set screw fully counter-clockwise for
open center, or fully clockwise for closed
center.
Step 3: Tighten jam nut.
WARNING:
Hydraulic fluid escaping under pressure can be almost invisible and can have sufficient
force to penetrate the skin. When searching for suspected leaks, use a piece of wood or cardboard
rather than your hands. If injured, seek medical attention immediately to prevent serious infection or
reaction.
