Be very careful when mowing uneven or rough ground. Do not operate the lawn tractor near embankments, dropoffs or ditches. The lawn tractor could suddenly turn over [...]

OPERATION Operation on Slopes Never mow on a sloped surface greater than 10 degrees (17% grade), since this can cause the lawn tractor to tip over. Use a slower speed for better control, and avoid sudden stops or starts when on a sloped surface. If you are unsure of the grade, obtain an inclinometer from a hardware store to measure the area in ques[...]

OPERATION Starting on a Sloped Surface Improper starting on sloped surfaces can cause the lawn tractor to lose traction and tip over. The lawn tractor can fall on you and cause serious inju- or death. Use the following procedure if you must start the lawn tractor on a sloped surface. 1. Press the brake pedal all the way down and hold it there. 2. R[...]

OPERATION A worn, cracked, or damaged blade can break, and pieces of the damaged blade can become dangerous projectiles. Thrown objects can cause serious injury.

OPERATION MOWING TIPS Here are some tips for getting a quality cut with your lawn tractor. When to Mow A well-groomed lawn requires mowing at short, regular intervals. During the growing season, a lawn may require mowing twice a week. Cutting Height To prevent possible damage to the mower deck, always raise it to the TRANSPORT position when driving[...]

OPERATION Cutting Width Allow an adequate amount of overlap in the cutting path when mowing. Four to six inches is recommended; this is roughly the same width as a front tire. When overlapping in a curve, use a lower speed, and overlap the previous cut by 50%, or about half the width of the mower deck. In extremely tall or thick grass, you may have[...]

OPERATION Fallen Leaves When equipped with an optional grass bag kit, your lawn tractor can be used to pick up fallen leaves for disposal. Adjust the height of the mower deck as needed to get the best results. When equipped with an optional mulching kit, you can mulch fallen leaves into your lawn. Don’t let the leaf cover get too deep before you [...]

OPERATION Trimming Tips l Turn to the left around trees, bushes, etc. l Drive slowly. Avoid hitting trees, bushes, etc. l If ground slopes up to a tree or bush, you may have to approach the tree or bush straight-on to avoid scalping. To Avoid Scalping l Pay attention to the way you drive. You can eliminate scalping. l If mower scalps easily, cuttin[...]

AFTER MOWING Under most conditions, the lawn tractor accumulates clippings, mud, dirt and other debris on the mower deck and other areas. Frequently, such debris contains moisture, which if allowed to remain on the mower frame, mower deck or other metal parts, can form rust. Regular cleaning not only helps prevent such rusting, but also makes the l[...]

OPERATION TOWING An optional rear hitch kit is specifically designed for your lawn tractor. Do not use any other type of hitch on the lawn tractor.
