Page 21: Motion Control Linkage Adjustment
Brake Adjustment See your authorized Yazoo/Kees dealer for any park brake adjustment. CAUTION! Keep hands, feet and clothing away from rotating tires. -
Page 22: Controls
This operator’s manual describes the Yazoo/Kees Zero Turn Rider. The rider is fitted with a Kawasaki or Kohler four-stroke V-Twin engine developing 20-25 horse power.* * As rated by the engine manufacturer. ROPS Fuel Cap English CONTROLS Transmission from the engine is made via two belt- driven hydraulic pumps, which in turn drive a hydraulic motor for each drive wheel. -
Page 23: Motion Control Levers
Motion Control Levers The machine’s speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or backward about a neutral position. Furthermore, there is a neutral position, which is locked if the steering controls are moved outward. -
Page 24: Tracking
Tracking If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (1 bar). Tracking must be checked on a flat and level concrete or blacktop surface. The tracking knob is located in front of the left control lever. -
Page 25: Refueling
Refueling The machine has two fuel tanks, one on each side just behind the seat. The tank capacity is 5.7 gallons (17 liters). The engine will run on a minimum of 87-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. Methanol fuel is not allowed. -
Page 26: Ignition Switch
Ignition Switch The ignition switch is placed on the driver’s control panel and is used to start and stop the engine. IMpORTANT INfORMATION Do not run the starter for more than five seconds each time. If the engine does not start, wait about 10 seconds before retrying. -
Page 27: Throttle Control
Throttle Control The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the blade switch is pulled out, see Engaging the Mower Deck. In order to increase or decrease the engine speed, the control is moved. -
Page 28: Mower Deck Cut Height Lift Lever
Mower Deck Cut Height Lift Lever The lifting lever is used to place the mower deck in the transport position or one of the 14 different cutting height positions. The cutting height is set by placing a peg in the hole for the desired cutting height and the peg is then locked on the inside (hidden in the illustration) with the supplied pin. -
Page 29: Operation
Read “Safety Instructions” section and following pages, if you are unfamiliar with the machine. Training Zero turn mowers are far more maneuverable than typical riding mowers due to their unique steering capabilities. We suggest that this section be reviewed in its entirety prior to attempting to move the mower under its own power. -
Page 30: Before Starting
Before Starting • Read the sections on Safety Instructions and Controls before starting the machine. • Perform the daily maintenance before starting (see Maintenance section). • Check that there is sufficient fuel in the fuel tank. • Adjust the seat to the desired position. The following conditions must be fulfilled before the engine can be started: •... - Page 31 • Move the steering controls outward to the locked (outer) neutral position. • Move the throttle to the middle position. • If the engine is cold, the choke control should be pulled out to its extent. • Press in and turn the ignition key to the start position.

Page 32: Weak Battery
Weak battery If your battery is too weak to start the engine, it should be recharged. (See “Battery” in the Maintenance Section.) If “jumper cables” are used for emergency starting, follow this procedure: To attach jumper cables • Connect each end of the RED cable to the POSITIVE (+) terminal on each battery, taking care not to short against chassis. -
Page 33: Running
Running Release the parking brake by moving the lever downward. Your mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake will shut off the engine. -
Page 34: Operating On Hills
Operating on hills Read the Safety Instructions “Driving on Slopes” in the “Safety Instructions”. WARNING! Do not drive up or down hills with slopes greater than 10 degrees. Do not drive across slopes. • The slowest speed possible should be used before starting up or down hills. -
Page 35: Mowing Tips
Mowing Tips • Observe and flag rocks and other fixed objects to avoid collisions. • Begin with a high cutting height and reduce it until the desired mowing result is attained. The average lawn should be cut to 2½" (64 mm) during the cool season and over 3" (76 mm) during the hot months. -
Page 36: Stopping The Engine
Stopping the Engine Allow the engine to idle a minute in order to attain normal operating temperature before stopping it, if it has been worked hard. Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling. -
Page 37: Moving Manually
Moving Manually When pushing or pulling the mower, be sure to open the release valves on both hydraulic pumps. Always turn off engine before engaging or disengaging the hydro release. Never attempt to adjust the bypass linkages with the engine running. The hydro release valves are located below the seat, on the front side of the hydro pumps. -
Page 38: Maintenance
