Engaging the Wheel Drive The DR ALL-TERRAIN FIELD and BRUSH MOWER has a four-speed forward transmission and single-speed reverse. Forward speeds range from 1.1 mph in first gear to 4.5 mph in fourth gear. Use the lower gears for mowing in thick, woody vegetation and the higher gears for wide-open areas and lighter vegetation, or as "travel gears." Reverse is ideal for maneuvering in tight spots. Note: Always release the wheel clutch lever (see mower picture, Figure 1, on page 10) when shifting gears. 1.
Stopping the Engine 1. Disengage the blade by pulling the Blade Control Lever (see Figure 1, on page 10) back to the DISENGAGED position. 2. Move the Shift Lever to the N (Neutral) position. 3. Move the Throttle Control to the IDLE position. 4. Turn the Key to the OFF position and remove it for safety. 5. Set the Parking Brake. Note: If your machine is equipped with a fuel shut-off valve, close it when transporting or storing the mower.
Slopes WARNING! When operating the DR ALL-TERRAIN FIELD and BRUSH MOWER over uneven terrain or slopes, use EXTREME CAUTION not to tip the machine over. 1. Do not use the DR ALL-TERRAIN MOWER on slopes greater than 20 degrees. Doing so could result in serious injury or damage to your machine. 2. To avoid freewheeling, shift into a lower gear before going down a slope. Do not shift while on a slope. 3.
Cutting Brush & Saplings 1. When cutting woody material, small saplings, etc., allow the machine to ride up and over material slowly. Adjust your forward speed to varying conditions (Figure 9). 2. After cutting brush, etc., you may want to mow over it again to remove any remaining branches. It works best to mow from the trunk end toward the top as brush lies on the ground. Reverse Figure 9 1. Be very careful of your footing when operating the machine in reverse. Know what's behind you and take your time.
