Testing Safety Systems



c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Do not run an engine in an enclosed area, such as a garage, even with doors or windows opened.

Move the machine to an outside area before running the engine.

The safety systems installed on your machine should be checked before each machine use. Be sure you have read the machine operator manual and are completely familiar with the operation of the machine before performing these safety system checks.

Use the following checkout procedures to check for normal operation of machine.

If there is a malfunction during one of these procedures, do not operate machine. See your authorized dealer for service.

Perform these tests in a clear open area. Keep bystanders away.

Testing Operator Presence Control

1. Hold the operator presence control against the drive handle.

2. Start engine.

3. Release operator presence control.

c CAUTION: Avoid injury! Rotating blades are dangerous. Do not look under mower or put hands under mower to view blade rotation. Listen for blades to stop.

4. Listen for blade and engine to stop. Do not look under mower to check blade.

Result: Blade and engine should stop within three seconds.

If blade and engine continue to run, there is a problem with your machine safety system. See your John Deere dealer.

Starting and Stopping Engine

c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Using Neutral Lock


MX27733

Picture Note: Shown in locked position.

When engaged, the neutral lock prevents the drive handle from moving forward and engaging the drive unit.

Use the neutral lock to lock the drive handle in a stationary position for starting and transporting the machine or operating in a push mode. The neutral lock should not be used to lock the drive handle in the forward position.

To engage the neutral lock, pull the drive handle all the way back, and push the neutral lock (A) fully forward. This will prevent the drive handle from moving forward and unexpectedly engaging the drive unit.

To disengage the neutral lock, simply pull the lever fully backward. This will allow the drive handle to operate normally.
