SET-UP 1. Engine must kill if blades are engaged without O.P. levers held down. 2. Engine must kill if the thumb latches are unlocked without holding O.P. levers down. 3. Engine must not start unless the blades are disengaged and the drive levers are locked in the thumb latches. 4. Do not operate the mower if the interlock safety system allows operation or starting in any unsafe condition.
OPERATION CONTROLS: Be thoroughly familiar with all controls their function and how to operate them before operating the mower. 2 8 12 12 4 11 6 3 10 8 FIGURE 9 1 FIGURE 10 NOTE: To begin motion the operator must move the ground speed lever forward before unlocking the thumb latches. After you unlock the thumb latches, allow the drive levers to move down at the same time. The mower will move in a straight line forward.
OPERATION 9 BYPASS POSITION DRIVE POSITION BRAKE POSITION FIGURE 11 3. Blade engagement switch: Located in the middle of the console. To engage the blades pull up on the switch, to disengage the blades push down on the switch. 4. Choke: Located on the left side of the console. Use when starting cold engine do not run choke when engine is warm. Use the throttle to control the engine RPM. 5. Tracking knob: Located under the console towards the front right corner.
OPERATION STARTING: 1. Making sure the blades are disengaged, drive levers are locked in the thumb latches, brake/ bypass lever is in the drive position and the fuel valve on. 2. Adjust choke (if needed) turn key to on position. 3. Pull start the engine. Once the engine is running adjust the throttle. 4. Holding down at least one of the operator presence levers, engage blades and set RPM to maximum, but not choked. NOTE: Be sure all persons are clear of area before engaging the blades.
MAINTENANCE 1. Engine oil level: Check daily with engine cold and on a flat surface. Remove the dipstick and wipe clean. Reinsert the dipstick all the way, but do not screw down. Remove the dipstick and check oil level. If oil level is low add oil. Use engine manufacturers specs for type of oil. 2. Mower blades: Stop engine and remove key. Inspect blades and sharpen or replace as needed. Check daily or more often if needed. The machine requires more power with dull blades and gives a poor cut.
MAINTENANCE 6. Engine oil: Change oil to manufacturers specifications. Stop engine and remove key. Drain oil when engine is warm. Loosen the 3/8” hex head on the oil drain valve at the right rear of the engine block. Be sure that the oil drain hose is on the drain and securely tightened. Retighten the valve after oil is drained. Remove oil filter. After oil is drained, put a light coat of clean oil on the new filter gasket before installing. Install on engine.
MAINTENANCE CUTTER HOUSING SPINDLE ASSEMBLY Grease housings once weekly or every 40 to 50 hours of use. Use a good synthetic grease. Pump grease in until a small amount purges from the popet on the underside of the deck. Check the torque of the pulley bolt (45 ft/lbs) should be maintained.
MAINTENANCE WINTER STORAGE To prepare your Yazoo/Kees mower for winter storage, perform the routine maintenance and necessary adjustments and record the part numbers of worn or broken parts so they may be ordered and replaced before the next mowing season. Use only authentic Yazoo/Kees replacement parts to insure proper fit and the safety of your mower is maintained. Treat the fuel in the tank with a fuel stabilizer (such as STA-BIL). This will minimize the formation of fuel gum deposits during storage.
