Tractors with PowrQuad Plus transmission / AutoQuad II transmission (version I)

1. Move range shift lever (A) and reverse drive lever (B) to neutral.
2. Start the engine and wait 6-7 seconds.
3. Move the reverse drive lever to "forward" or "reverse", and release it there.

If the reverse drive lever remains in the selected position without being held there manually, the neutral start circuit is operating correctly.

If the reverse drive lever moves INSTANTLY by itself from "forward" or "reverse" to neutral without being moved by hand, then the neutral start circuit must be repaired by your John Deere dealer without delay.

Repeat the test in the other direction of travel.

Tractors with PowrQuad Plus transmission / AutoQuad II transmission (version II)

2. Start the engine and wait 6-7 seconds. Set reverse drive lever (B) to neutral position. The "N" on the display disappears (or has already disappeared).
3. Move the reverse drive lever to "forward" or "reverse".

If no alarm signal is emitted, the neutral start circuit is functioning properly.

Repeat the test in the other direction of travel.

If an alarm signal is emitted, the cause may be one of the following:

• the range shift lever is not in neutral. Repeat test.
• the transmission is in its "come-home" mode ("Come Home" relay is inserted). Repeat test.
• the neutral start circuit is defective. Have it repaired by your John Deere dealer.
