Operating on slopes

Refer to the slope gauge on the back cover to help determine slopes where you may
safely operate the mower.

WARNING: Do not mow on inclines with a slope in excess of 15° (25%) (a rise

of approximately 2-1/2 feet every 10 feet). The mower could overturn and

cause serious injury.

•  Mow across the face of slopes; never up and down.
•  Exercise extreme caution when changing direction on slopes.
•  Watch for holes, ruts, rocks, hidden objects or bumps which can cause you to slip or

trip. Tall grass can hide obstacles.

• Always be sure of your footing. A slip and fall can cause serious personal injury.
• Do not mow near drop-offs, ditches or embankments, you could lose your footing

or balance.

• Do not mow slopes greater than 15° (25%) as shown on the slope gauge.
• Do not mow on wet grass. Unstable footing could cause slipping.

setting Deck height

To adjust the deck height, adjust
the clevis pin location in the deck
adjustment pins and the deck lift
adjustment collars.

1. Securely grasp one of the

three handles on the deck (see
Figure 5 for location) and lift
slightly to remove the cotter
pin (a). See Figure 6.

2. Raise or lower the deck on the

deck adjustment pin (b) and in
combination with the deck lift
adjustment collar (c), find the
desired height. See Figure 6.

3. Insert the cotter pin

(a) back into the deck
adjustment pin (b) at
the desired position. See
Figure 6.

4. Repeat these steps for

the other three deck
adjustment pins making
sure the height is the
same for all four deck
adjustment pins.
