Determining Safe Slope Angles

Operating this machine on slopes can be dangerous. Rollover accidents can occur and can result in serious injury or death.

• John Deere has determined that the risk of rollover is low when this machine is operated on slopes of 10 degrees or less. The risk of rollover increases as the slope angle increases. Never operate this machine on slopes greater than 20 degrees.

• It is important to establish your own procedures and work rules for operating the machine on slopes. The procedures must include a survey of all mowing sites to determine which slopes can be operated on safely.

• Consider potential turf conditions, dips, and holes along with slope angles when determining a safe slope.

• Before allowing someone to operate this machine on a slope, make certain the slope is not too steep for safe operation.

• Make certain the operator is trained and capable of operating the machine safely on the slope.

1. Lay a straight piece of sturdy lumber 1.2 m (4 ft) long on the slope.
2. Measure the angle of the slope with an angle indicator or protractor level.
   • If slope is greater than 20°, do not mow.
   • If slope is 10° or less the risk for rollover is low.
3. Repeat procedure at several points on the slope to get an overall idea of the slope angle. Do not operate the machine on any areas that exceed the manufacturer’s recommended slope angle.
