Cutting Speed To improve cut quality, use a slower ground speed in certain conditions. 1 Avoid Cutting Too Low If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short. m–5028 Figure 28 1. Lift assist lever Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
3 5 4 MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 2 1 m–2539 3 Figure 31 4 M–4226 3. Rotate the opposite ends of the blades forward. Measure from a level surface to the cutting edge of the blades at the same position as in step 2 above. The difference between the dimensions obtained in steps 2 and 3 must not exceed 1/8 inch (3 mm). If this dimension exceeds 1/8 inch (3 mm), the blade is bent and must be replaced; refer to Removing the Blades and Installing the Blades, page 30. Figure 32 1.
Installing the Blades Cleaning the Paper Elements 1. Install the blade onto the spindle shaft (Fig. 32). 1. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 36). Important The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. 2. Inspect the element for tears, an oily film, and damage to the rubber seal. Important Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene.
USE THESE SAE VISCOSITY OILS 1. Start the engine and let it run for five minutes. This warms the oil so that it drains better. 2. Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely. Disengage the power take off (PTO), set the parking brake, stop the engine, and remove the key. 3. Place a pan below the oil drain. Rotate the oil drain valve to allow oil to drain (Fig. 38). 4. When the oil has drained completely, close the drain valve.
Danger 3 Rotating shaft and fan can cause personal injury. 1 2 • Do not operate the machine without the covers in place. • Keep fingers, hands and clothing clear of rotating fan and drive shaft. • Shut off the engine and remove the ignition key before performing maintenance. m–1256 Figure 39 1.
