BE FORE YOU START There is NO OIL in the crankcase of the engine when shipped from the factory. Read Engine Manual and follow all instructions pertaining to type of lubrication specified. The engine is the heart of your Lawn Ranger and it is very important that you keep it in good condition. Before mowing, the mower should be operated at a slow speed to check all moving parts for any damage or looseness caused in transporting. Lubricate all grease fittings with a regular pressure gun lubricant every eight to ten hours of operation. Refer to Figure I for the location of grease fittings. A light machine oil should be used on all moving parts to keep joints from wearing and squeaking. Remove oil filler plug. located at the left rear side of the transmission, and fill to level of hole with a good grade of S.A.E. 90 Gear Lube (will require about 3 pintsj. The transmission should be checked after every 0 hours of use. The transmission should be drained once a year by removing plug on bottom to drain oil. Ref, II as above paragra ph. This is a regular automotive type transmission with sliding gears and should have the same care as your car. BATTERY The battery installed in the Model BE is a dry charged battery. It is important that you properly prepare this battery to insure good service and long life.. Remove vent caps. Remove or destroy any sealing device which may have been used to close or restrict the vent openings.. Fill each cell of the battery to the proper level with the battery electrolyte. NOTE: Temperature of battery and electrolyte at time of filling should be above 60"F. Never fill battery in the vehicle. 3. BOOST CHARGE: 5 amps. for 0 minutes or 7 amps. for 30 minutes. Adjust electrolyte level, if necessary, after charge.. Install battery with battery posts toward the rear of mower. Start motor. Check to see if generator is charging properly. After battery has been in service, add only approved water. DO NOT ADD ACID. TIRE S The front tires are 3.50 x pneumatic and should be filled to 0 pounds of air pressure. The rear tires are.00 x 8 and should have 6 to 8 pounds of air pressure. STARTING ENGINE. Before starting the engine open valve on sediment bowl.. Place gear shift lever in neutral position, lower the rotary mower to the ground on its gage wheels, ma ke certain that the mower clutch is latched in the disengaged position. 3. Pull throttle lever Yz way out and turn to the right to lock it in position. Note: The Throttle control has a locking device. Turn the throttle control to the left to unlock, adjust to the desired position and turn to the right to lock.. Pull choke lever all the way out to choke engine. If engine is warm and has been running, choking will not be necessary. 5. A. Model 33R has a recoil starter with an OFF and ON switch. To start push switch to ON position and pull recoil starter. (NOTE: Keep feet clear of mower while pulling recoil starter.) B. Model 33E has an OFF and ON key. also a starter button. Turn key to ON position and push starter button. 6. When engine starts push choke in to off position and regulate throttle control by turning to the left to unlock and push in or out to desired speed. 7. Depress clutch pedal on left side of the Lawn Ranger before selecting desired gear ra nge. 8. When starting the Lawn Ranger in winter it is desirable to de press clutch so starter does not have to turn transmission. CLUTCHING There is no need to force the gear shift lever if the gears do not immediately mesh. Depress clutch pedal all the way down and let up, then depress again and shift. To avoid sudden starts, release clutch pedal slowly. While in motion do not shift gears without depressing clutch pedal. The clutch pedal also operates the brakes WHEN DEPRESSED ALL THE WAY DOWN. For this reason, you should depress the clutch pedal ONLY % OF THE WAY DOWN WHEN SHIFTING while in motion. This clutch-brake pedal combination makes clutching automatic as you apply the brakes to stop. PARKING BRA KE The parking brake is located on the left side of the Lawn Ranger as shown in Figure I. To set the parking brake depress the clutchbrake pedal as far as possible and push the parking brake forward. To release the brake depress the clutch-brake pedal and pull the parking brake back.

CARE OF THE LAWN RA NGER. Keep the Lawn Ranger greased and oiled regularly. Refer to to Figure I for the location of grease fittings. Check transmission and engine case oil levels.. Keep engine air cleaner clean. This will add to engine life. 3. Keep tires properly inflated. See previous instructions.. Keep the Lawn Ranger covered and in a dry place when not in use.. 5. Keep grass and dirt out of engine cowling as these will stop the flow of air and decrease engine life. 6. BRAKE ADJUSTMENT. The brake band, located on the left side of the transmission, bra kes the transmission and in turn stops the wheels. Adjust the nut on the bra ke rod so that, when you depress the clutch pedal all the way down. the band tightens around the brake drum. just as the idler pulley releases the belt. Keep brake band and drum free from oil and dirt. 7. Clutch.Brake Pedal Ad'justment. The clutch-brake pedal rod may be turned in or out to adjust the pedal to operator's desired position. Remove pin from rod and turn rod in or out for adjustment. S. When blades become dull, remove and regrind. CAUTION: Sharpen evenly on both sides so blade does not become out of balance. 9. On the Model BE,check battery after every 0 hours of use. If the mower has been in storage it may be necessary to recharge. 0. Your Lawn Ranger is only as good as the service you give it.

Remove key when not in use - children could get hurt. 7. Don't overspeed the engine. Excessive cutting speed or tamper ing with the governor can 'be dangerous. S. The ower has side plates which may be removed when cutting heavy grass or weeds. The sideplates may be reinstalled in an inverted position, as shown by the dotted illustration, thus acting as an additional foot guard. EXTREME CAUTION should be exercised when the sideplates are removed, because of the danger of flying debris. 9. Exercise special care when mowing around objects to prevent the blades from striking them, and never deliberately mow over any object. 0. Stop operation when another person approaches - prohibit others from riding with you on your riding mower.. Riding mowers can be tipped to either back or side. Exercise extreme ca ution when mowing on slopes or inclines. Engage clutch slowly and smoothly. Never abuse your mower by improper handling.. Never adjust mower or tractor until engine has been turned off. 3. If your Lawn Ranger is to be used for purposes other than mowing, latch mower clutch in disengaged position, stop engine and remove mower drive belt from engine pulley. The spring wire belt stop may be deflected to remove belt. Never allow children to operate unless you have removed this belt to prevent their accidentally engaging mower.

This foot rest CAN NOT be used when mowing.) :--'PAIIKIIG BRAKE Figure "'--' OPERATION With proper care and adjustment. your new Wheel Horse Lawn Ranger has been designed to give. many years of satisfactory performance. Preparation for operation and operating hints listed below are recommended for all mowers and approved by the Outdoor Power Institute for safe operation of your mower.. Before starting operation, clear the entire lawn area of all debris that could catch on to or be thrown by the blades.. When you mow on rough terrain or in high grass or weeds. the blade should be set at the highest cutting point. In tall grass or weeds. a second cutting may be made to bring the grass down to the desired height. 3. Mowers do not operate as well in wet grass. Wet grass has a tendency to build up on mower housing and give non-uniform discharge.. Fill gas tank outdoors. Avoid spilling gasoline and don't fill the tank while engine is running or while you are smoking. WHEEL HORSE LAWN RA NGER SPECIFICATIONS (SPECIfICATIONS SUBJlfCT TO CHANGIf WITHOUT NOTICIf!
