Troubleshooting Adjustments & Service TROUBLESHOOTING WARNING While normal care and regular maintenance will extend the life of your equipment, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly. To avoid serious injury, perform maintenance on the tractor or mower only when the engine is stopped and the parking brake engaged. The troubleshooting guide below lists the most common problems, their causes and remedies.
Troubleshooting, Adjustment & Service TROUBLESHOOTING THE RIDER (CONTINUED) PROBLEM CAUSE Engine runs, but rider will not drive. Rider drive belt slips. Brake will not hold. Rider steers hard or handles poorly. REMEDY 1. Ground speed control lever in neutral. 2. (Hydro models only) Transmission release lever in “push” position. 3. Belt is broken. 4. Drive belt slips. 5. Brake is not fully released. 1. Clutch is out of adjustment. 2. Pulleys or belt greasy or oily. 3. Belt stretched or worn. 4.
Troubleshooting, Adjustment & Service SEAT ADJUSTMENT WARNING Use the lever on the front of the seat (See L, Figure 1 on page 6) to adjust the seat forward or rearward for best rider comfort. To avoid serious injury, perform adjustments only with engine stopped, key removed and rider on level ground. STEERING GEAR ADJUSTMENT *2401 Capscrews If there is excessive slack in the steering system, the steering gear can be reindexed to the steering shaft. 1. See Figure 22.
Adjustments BRAKE ADJUSTMENT 2 9/16" – 2 5/8" Brake Adjustment - Gear Models 1. Place the transmission in gear and release the parking brake. 2. Move the brake lever (B) forward. There should be a 1/8" gap between the lever (B) and the stop (C) as shown in Figure 24. 3. To adjust clearance, turn nut (D) clockwise to decrease the gap or turn nut counterclockwise to increase the gap. 4. Set the parking brake.
Adjustments MOWER ADJUSTMENTS WARNING If the cut is uneven, the mower may need leveling. Unequal or improper tire pressure may also cause an uneven cut. Make sure tire pressure is correct as specified in Checking Tire Pressure. To achieve proper mower levelling, perform Side-To-Side Leveling, Front-To-Back Leveling and Transport Height Adjustment procedures, in order, as follows. Before checking mower, shut off PTO and engine. Allow all moving parts to stop.
Adjustments *2399 Figure 28. Leveling The Mower Side-to-Side A. Nut B. Eccentric Nut C. Rear Rollers Front-To-Back Leveling *2397 1. Make sure mower is level side-to-side and that rear rollers are on the ground. 2. Position blade(s) front-to-back. Measure the distance from the ground to front tip of blade(s), and from ground to rear tip of blade(s). On 30” mower, the front tip should be level to 1/8” (3 mm) higher than rear tip.
Adjustments Transport Height Adjustment Transport height should be adjusted so that rear mower rollers are 1/8” - 1/4” (3-6 m) above ground when mower lift lever is in transport position. To adjust, perform both mower leveling procedures first, then do the following procedure. See Figure 30. 1. Park rider on a flat level surface. 2. Adjust Dial-A-CutTM control so that front edge of mower lift lever is aligned with 2-3/4” mark (34” mower) or at 3” mark (30” mower) on the quadrant scale. 3.

Lawn Care & Mowing Information GENERAL INFORMATION Proper mowing is an important part of maintaining your lawn in the best possible condition. A healthy and well maintained lawn is better able to resist drought, weeds, and other stresses. But too much maintenance is as detrimental to your lawn as neglect. Proper care for your lawn involves more than just “cutting the grass.
Lawn Care & Mowing Information HOW HIGH TO MOW THE GRASS Cut less than 1/3 Often cutting height is a matter of personal preference. Typically, you should mow the grass when it is is between three and five inches high. The proper cutting height range for a specific lawn will depend upon several factors, including the type of grass, the amount of rainfall, the prevailing temperature, and the lawn’s overall condition.
Lawn Care & Mowing Information WHEN AND HOW OFTEN TO MOW The time of day and condition of the grass greatly affect the results you’ll get when mowing. For the best results, follow these guidelines: ● Mow when the grass is between three and five inches high. ● Mow with sharp blades. Short clippings of grass one inch or shorter decompose more quickly than longer blades. Sharp mower blades cut grass cleanly and efficiently, preventing frayed edges which harm the grass.
Lawn Care & Mowing Information MOWING METHODS Proper Broadcast Mowing Broadcasting, or side-discharging, disperses fine clippings evenly over the entire lawn. Many golf courses use this method. Your mower has a deep dish deck to allow freer circulation of clippings so they are broadcast evenly over the lawn. ENGINE SPEED & GROUND SPEED FOR BROADCASTING Always operate the engine at full throttle when mowing.
Lawn Care & Mowing Information ✘ Reduce the evaporation of water from your lawn. TIPS On Dealing With Clippings Clippings are beneficial to your lawn. A common misconception about clippings is that they automatically lead to thatch—this is untrue. Short clippings produced by broadcasting and clippings produced by mulching methods actually contribute to a healthy lawn because they: ✘ Provide a cushioning layer to reduce lawn wear. ✘ Moderate soil temperature.
