CONTROLS Presentation This operator’s manual describes the Yazoo/ Kees Lever-Steered Rider Mower. The mower is fitted with a liquid cooled, 3 cylinder Daihatsu diesel engine (27 HP) or Daihatsu Turbo diesel engine (34 HP). Transmission from the engine is made via two belt-driven hydraulic pumps, which in turn drive a hydraulic motor for each drive wheel. Using the left and right steering controls, the flow is regulated and thereby the direction and speed.
CONTROLS Gauges Water temperature gauge- indicates coolant temperature and warns of overheat situation. Ammeter - indicates amount of electrical flow at the battery. Under normal operating conditions the needle will be slightly on the plus (+) side of the gauge, showing that current is being supplied to the battery. At idle speed, the indicator may be at zero or on the negative (-) side.
CONTROLS Engaging the Mower Deck In order to engage the mower deck, pull the knob out; the mower deck is disengaged when the knob is depressed. Deck should be engaged at mid throttle and disengaged at idle speed to prolong clutch life. Engaging the mower deck BAM-2 Parking Brake The parking brake is found on the left of the machine. Pull the lever back to activate the brake and push forward to release it.
CONTROLS Motion Control Levers The machine’s speed and direction are continuously variable using the two motion control levers. The motion control levers can be moved forward or backward from a neutral position. Furthermore, there is a neutral position, which is locked if the motion control levers are moved outward into the neutral slots. When both controls are in the neutral position (N), the machine stands still. The motion control levers on each side of the mower control the direction of movement.
CONTROLS If the steering controls are in uneven positions when standing still, they can be adjusted using the adjustment screws, not the link system, for the controls ADJUSTIN GSCREWS Adjusting screws Hydraulic Lift Switch Used to raise and lower the mower deck hydraulically. Only used on units with power deck lifts. Push switch forward to lower the deck and pull backward to raise the deck.
CONTROLS Refueling The machine has two fuel tanks, one on each side just behind the seat. The tanks hold 11.4 gallons, 5.7 gallons each. The engine is run on clean, fresh, diesel fuel with a minumum of 40 cetane. WARNING! Diesel fuel is highly flammable. Observe caution and fill the tanks outdoors (see the safety rules). BAM-8 Fuel tanks Fuel Shut-Off The fuel shut-off is placed to the right side of the seat. The shut-off has three positions; right tank, left tank and off position.
CONTROLS Manual Lifting Lever with Foot Assist for the Mower Deck The lifting lever is used to place the mower deck in the transport position or one of the 17 different cutting height positions. The cutting height is set by placing a pin in the hole for the desired cutting height and the pin is then locked on the inside (hidden in the illustration) with the supplied cotter pin. 1. Pull the lever backward while pushing on the foot pedal, lifting the deck to the locked position. The deck is then raised. 2.
CONTROLS Relays The relays and glow plug timer are located in a holder to the right side of the seat.

On power units push the hydraulic lift switch forward to lower the deck to the selected pin position. IMPORTANT INFORMATION The mower deck’s anti-scalp rollers should be evenly adjusted. See Maintenance section.
OPERATION disengaged before the motion control levers can be moved from the neutral slots or the engine will kill. By moving the levers an equal amount forward or back the machine will move in a straight line in that direction. Movement of either lever forward will cause the right or left wheel to rotate in a forward direction. To stop movement pull both levers into the neutral position.
OPERATION dense, the driving speed can be increased without noticeably depreciating the mowing result. • The finest lawns are obtained by mowing often. The mowing becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher driving speed can be used without poorer mowing results. • Avoid mowing wet lawns.
OPERATION 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.

MAINTENANCE Checking the Safety System The machine is equipped with a safety system that prevents starting or driving under the following conditions. The engine can only be started when: 1. The mower deck is disengaged. 2. The motion control levers are in the outer, locked neutral position. 3. The driver is sitting in the driver’s seat. 4. The parking brake is on. Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met.
MAINTENANCE Checking the Engine’s Cooling Air Intake Check that the engine’s cooling air intake is free from leaves, grass, and dirt. If the cooling air intake is clogged, engine cooling deteriorates, which can lead to engine damage. The radiator screen can be removed and cleaned . Checking and Adjusting the Throttle Cable Check that the engine responds to throttle Check and clean the cooling air intake increases and that a proper engine speed is attained at full throttle.
MAINTENANCE Replacing the Air Filter If the engine seems weak or runs unevenly and the dust load indicator has turned red the air filter may be clogged. If run with a clogged air filter, disruption of operation can occur. CLAMP Cleaning/replacing the air filter is carried out as follows Only do so when the dust indicator is red. DUST LOAD INDICATOR CLAMP WARNING! Allow the exhaust system to cool before performing service. Risk for burns. 1.
MAINTENANCE Replacing the Fuel Filter The fuel filter is located with the priming pump. Replace the fuel filter every 800 hours (once per season) or more regularly if it becomes clogged. PRIMING PUMP Replace the filter as follows: Unscrew fuel filter from pump and replace. Every 50 hours check for water in the fuel filter. Empty if necessary. Refer to the engine manual. FUEL FILTER Checking Tire Pressures All four tires shall have a pressure of 16 PSI.
MAINTENANCE When refilling the system, it is important that all trapped air be purged. The following procedure will help to insure this: 1. Make sure the engine is level. Fill the overflow reservoir up to the MAX mark with coolant mixture. 2. Slowly fill the radiator to the bottom of the filler neck with coolant mixture. 3. With radiator cap off, start the engine and let it warm up (no-load). Then, if necessary, add more coolant mixture to bring the level back up to the bottom of the filler neck. 4.
MAINTENANCE contact between brake shoes and drum can be felt. Hold in this position. 4. Rotate clevis until clevis pin can just be inserted thru clevis and brake lever with pin resting against rear of the hole in brake lever. 5. Remove clevis pin and rotate clevis two (2) full turns toward rear to allow correct clearance between brake shoes and drum. 6. Temporarily reinstall clevis pin (do not install cotter pin) to keep clevis from turning and tighten jam nut. 7.
MAINTENANCE Checking the Hydraulic System Total System Capacity..................1.125 gal. To check the hydraulic fluid level, locate the hydraulic reservoir under the seat. Remove cap and check level. Fill to 1/4" from top of tank WARNING! If a leak is suspected, use a piece of cardboard or wood, NOT your hands. to check for leaks. Escaping hydraulic oil under pressure can have sufficient force to penetrate the skin, causing serious injury. Ifinjured by escaping fluid, see a doctor at once.
MAINTENANCE Caster Wheels Check every 200 hours. Lift front of unit off of ground so caster wheels can rotate freely. Tighten caster bolt then back off 1/2 turn. Check that wheel rotates freely. If wheel does not rotate freely back the caster bolt off in 1/4 turn increments until wheel rotates freely. NOTE: DO NOT add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires will cause premature failures. Only use O.E.M. specified tires.
MAINTENANCE Begin with either side and put the motion control lever into the neutral position. Adjust the motion control linkage by rotating the double nuts (D) in the proper direction until the wheel stops rotating. See illustration. Move the motion control lever forward then into the neutral position and place it into the neutral slot. The wheel must be stopped completely at this point. Now do the same in reverse and release the lever. The lever should return to neutral on its own.
