7. USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

SLOPE OPERATION

1. Slopes are a major factor related to slip and fall accidents, which can result in severe injury. All slopes require extra caution and slow speed. If you feel uneasy on a slope, DO NOT mow it.

2. Mow across slopes, never up and down. Exercise extreme CAUTION when changing directions on slopes. Practice operation of machine on slopes with blades off.

3. Use extra care with grass catchers or other attachments: these affect the handling and the stability of the machine.

4. DO NOT use tow behind attachments on slopes.

5. AVOID uphill starts.

6. Turf conditions can affect the machine’s stability. DO NOT operate machine under any condition where traction, steering or stability is doubtful.
