2. Make sure key switch is in OFF position.

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

   Load center is behind seat.

   Remove cover to access fuses. (See Accessing Fuses And Relays in Maintenance—Electrical System section.)

4. Remove plastic keeper from fuse location 24 and 28.

5. Remove 10 amp fuse # 32 (B) move to fuse location 28 (C).

6. Move fuse # 17 (D) to fuse # 24 (A) location.

7. Turn key to ”Run” (not ”Start”) position. SERVICE ALERT indicator light will flash. After five seconds, STOP indicator light will also flash.

8. Turn key to ”START” position and crank engine 10 — 15 seconds. Release key and make sure it is in RUN position.

9. 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.

10. 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.

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

11. 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.

    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”, cranking engine for 10-15 seconds, then release to ”RUN” position.

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

13. Move fuses from fuse # 24 location (A) back to fuse #17 location (D) and from fuse #28 location (C) back to fuse # 32 location (B).
