Releasing Park Brake (AutoPowr Transmission)

causym CAUTION: Avoid possible injury if tractor moves. Block tires to prevent tractor from moving when park brake releases. Procedure requires an operator seated in the tractor to monitor park brake release procedure.

1. Block tractor tires.

2. Disconnect "Tow Collar" by moving linkage (A) forward to place roll pin in front of latch (B).

NOTE: Moving fuses allows engine to be cranked without starting.

4. Remove and save fuse isolator from F2 and F3 fuse locations.

5. Move fuse 9 to location 3 and fuse 4 to location 2.

7. Turn key to "Start" position, hold for 15 seconds, then release to "Run" position. SERVICE ALERT indicator light should continue to flash, and park brake should release.

8. If STOP indicator light flashes instead, there is not enough hydraulic pressure to release park brake. Repeat Step 6 up to two more times. If SERVICE ALERT light does not flash, contact your John Deere dealer.

causym CAUTION: Minimize chance of possible injury from an accident. Always use seat belts when operating the tractor.

Turning key switch to the "OFF" position while towing tractor will cause sudden engagement of the park brake, locking the rear wheels. Avoid serious personal injury by making sure the key switch remains in the RUN position anytime tractor is towed, unless emergency stop is required.

9. Depress brake pedals while an assistant removes tire blocks. Proceed with towing, observing towing precautions stated in TOWING TRACTOR, in this section.

causym CAUTION: Avoid possible injury. If park brake starts to drag repeatedly even after performing Step 8, system is unable to maintain sufficient pressure to keep park brake released. Signal tow vehicle driver to stop immediately, as park brake may engage suddenly. Person in towed tractor should apply wheel brakes at the same time.

10. Every 30 minutes, or if STOP light starts flashing and warning horn sounds continuously and an associated message appears on the CommandCenter display, or if park brake drag is felt, signal tow vehicle driver to stop immediately. Person in towed tractor should apply wheel brakes at the same time as tow vehicle. Turn key switch to "START" position for 15 seconds, then release to "RUN" position.

11. After tractor has reached service area, depress brake pedals to bring tractor to a complete stop before switching key to "OFF" position.

12. Move fuses back from location 2 to 4 and from location 3 to 9.

13. Re-install fuse isolator to F2 and F3 fuse locations. Install access panel.
