g028043 Figure 30 1. Back the machine up the ramp. 2. Drive the machine forward down the ramp. Important: Do not use narrow individual ramps for each side of the machine. Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 31). On flat ground, this requires a ramp to be at least 4 times as long as the height of the trailer or truck bed to the ground.
Operating Tips raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower in uncut grass.

Note: The drain plug is attached to the drain hose. Note: Dispose of the used oil at a recycling center. Fill with oil as specified in the “Viscosity Grades” table (Figure 36). 1. Park the machine, so that the drain side is slightly lower than the opposite side, to ensure that the oil drains completely. 2.
g027517 Figure 40 g027477 Figure 39 6. Servicing the Spark Plug Slowly pour approximately 80% of the specified oil into the filler tube (Figure 40). Service Interval: Every 500 hours—Replace the spark plug(s). The spark plug is RFI compliant. Equivalent alternate brand plugs can also be used. Type: Champion XC12YC Air Gap: 0.76 mm (0.03 inch) Removing the Spark Plug 33 1.
Installing the Spark Plug Tighten the spark plug to 27 N•m (20 ft-lb) as shown in Figure 43. g027478 Figure 41 Checking the Spark Plug Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks. Note: If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. g028109 Set the gap to 0.76 mm (0.03 inch).
Cleaning the Blower Housing Fuel System Maintenance Every 100 hours/Yearly (whichever comes first) DANGER To ensure proper cooling, ensure that the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.
Electrical System Maintenance Servicing the Battery g028110 Service Interval: Monthly DANGER Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns. Do not drink electrolyte and avoid contact with skin, eyes or clothing. Wear safety glasses to shield your eyes and rubber gloves to protect your hands. Removing the Battery WARNING Battery terminals or metal tools could short against metal machine components causing sparks.
1. Charge battery for 10 to 15 minutes at 25 to 30 amps or 30 minutes at 10 amps. 2. When the battery is fully charged, unplug the charger from the electrical outlet, then disconnect the charger leads from the battery posts (Figure 46). 3. Install the battery in the machine and connect the battery cables. g028178 Figure 45 4. 5. 6. 7. Remove the clamp (Figure 45). First disconnect the negative battery cable (black) from the negative (-)(black) battery terminal (Figure 45).
Drive System Maintenance Checking the Tire Pressure Service Interval: Every 25 hours—Check tire pressure. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut. Check the pressure at the valve stem (Figure 49). Check the tires when they are cold to get the most accurate pressure reading. Refer to the maximum pressure suggested by the tire manufacturer on the sidewall of the caster wheel tires. Inflate the rear drive wheel tires to 90 kPa (13 psi).
Removing the Hydraulic Filters Hydraulic System Maintenance Important: When the hydraulic filter is removed, all of the hydraulic fluid in each transaxle will drain out. Use a container that holds 4.495 L (152 oz) or larger. 1. Shut off the engine, wait for all moving parts to stop, allow the engine to cool, remove the key, and engage the parking brake. 2. Locate the filter and guards on each transaxle drive system and remove the 3 screws securing the filter guard (Figure 51).
3. Bleeding the Hydraulic System Slowly pour the specified fluid through the expansion reservoir until fluid comes out of a vent-plug hole. 4. Install the vent plug and torque it to 20 N•m (180 in-lb). 5. Continue to add fluid through the expansion reservoir until fluid comes out of the remaining vent-plug hole on the second transmission. 6. Install the second vent plug and torque it to 20 N•m (180 in-lb). 7.
Mower Deck Maintenance Servicing the Cutting Blades Maintain sharp blades throughout the cutting season, because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth, and increases the chance of disease. g006530 Figure 54 Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
3. Measure from the tip of the blade to the flat surface (Figure 56). g009680 Figure 58 1. Opposite blade edge (in position for measuring) g009680 Figure 56 2. Level surface 3. Second measured distance between blade and surface (B) 1. Blade (in position for measuring) 2. Level surface 3. Measured distance between blade and the surface (A) 4. A. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 57).
3. Repeat this procedure until the blade is balanced. Installing the Blades 1. Install the blade onto the spindle shaft (Figure 59). Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. g010341 3. Curved washer 4. Blade bolt 3. Torque the blade bolt to 135 to 150 N•m (100 to 110 ft-lb). Ensure that the mower deck is level any time you install the mower deck or when you see an uneven cut on your lawn.
