1 LAWN TRACTOR SAFETY For your safety precautions: Operator l l l l l l l l l and the safety of others, pay special attention to these Responsibility Keep the lawn tractor in good operating condition. Operating a lawn tractor in poor, or questionable condition could result in serious injury. Be sure all safety devices are in working order and warning labels are in place, these items are installed for your safety. Know how to stop the engine and blades quickly in case of emergency.
Blade Hazard The blades are sharp, and they turn at high speed. Accidental contact can cause serious injury. l Keep your hands and feet away from the mower deck while the engine is running. l Stop the engine, disengage the Power Take Off (PTO) clutch and remove the key before inspection or maintenance of the deck or blades. l Disconnect the spark plug caps to prevent any possibility of accidental starting.

If you use an oxygenated octane rating requirement. fuel, be sure it is unleaded and meets the minimum Before using an oxygenated fuel, try to confirm the fuel’s contents.
AIR CLEANER Check that the air cleaner elements are clean and in good condition. A dirty air cleaner will restrict air flow to the carburetor, reducing engine performance. A damaged air cleaner will allow dirt to enter the engine, causing rapid engine wear. 1. Open the hood and remove the wing nuts to remove the air cleaner cover and air cleaner elements. 2. Inspect the air cleaner elements. Clean or replace the elements if necessary.
COOLANT Coolant Level Check the coolant level in the reserve tank when the engine is at normal operating temperature. It should be between the MAX and MIN marks. If the coolant mark. level is near the MIN mark, add coolant If there is no coolant in the reserve for leaks and repaired if necessary. and reserve tank. to bring it up to the MAX tank, the cooling system should be checked Coolant must then be added to the radiator m The coolant is hot and under pressure and severe scalding could result.

TRANSMISSION OIL INSPECTION Check the transmission fluid with the lawn tractor and the transmission at ambient temperature. parked on level ground NOTE: HST fluid changes its volume with changes of temperature. The dip stick is calibrated for HST fluid temperatures between 32OF (OOC) and 68OF (2OOC). Within this temperature range, the oil level should be between the upper and lower marks on the dip stick.
CUTTER DECK Prior to using the mower, be sure to check that dirt, mud, and grass have not built up in the deck. For cleaning, refer to page 77. CUTTER DECK DRIVE BELT AND BLADE BELT l Inspection 1. Lower the deck as far as it will go with the deck height adjusting lever, and raise the hood. 2. Inspect the belts for damage or excessive wear. If the belts are damaged or excessively worn, replace them as described on pages 66 - 69. CUTTER DECK DRIVE BELT BLADE BELT Cutter deck drive belt tension 1.
ANTI-SCALP ROLLER ADJUSTMENT The anti-scalp rollers help to prevent the blades from gouging or “scalping” high spots. The deck is designed to “float”‘, and it is important to set the anti-scalp rollers correctly. The setting depends on the type of terrain being mowed and the cut height. SLOPING OR UNEVEN TERRAIN FLAT TERRAIN For flat terrain, use the lower hole in the anti-scalp roller shaft. Align the hole with the hole on the deck that corresponds to the selected cutting height as shown.

While parked on a level surface, move the PTO lever to ON (Engaged). Rise off the seat-the engine should stop immediately. 2. Return the PTO lever to OFF (Disengaged) and restart the engine. Release the parking brake and place the shift lever in the slow mowing range.
MOWING Before operating this lawn tractor SAFETY INSTRUCTIONS on pages l l l l l you should 6 - 9. read and understand the Rotating blades and thrown objects can cause severe personal injury. Always stop the engine before clearing the discharge chute or removing the grass bags. Unseen hazards may cause loss of control or damage to the lawn tractor. Look for and avoid rocks, roots, holes, and hidden hazards in the terrain.
. . . . . . . . . . To avoid leaving uncut grass, engage the PTO before shifting the transmission from neutral to the desired mowing speed. For best cut quality and overall performance, set the throttle in the FAST position and select the proper mowing speed with the shift lever. Mowing at low or medium throttle settings will affect blade performance and cut quality. For best results, select a good mowing speed and stay at that speed. Rapid speed changes while mowing will affect cut quality.

HIGH ALTITUDE OPERATION At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich fuel mixture may also foul the spark plugs and cause hard starting. High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 1,800 meters (6,000 feet), have your dealer perform this carburetor modification.
6. TRANSPORTING m The engine and exhaust system become hot during operation and remain hot for a while after stopping. Touching hot engine or exhaust system can cause serious burns and can ignite some materials. Avoid touching the engine or exhaust system for at least the engine has stopped. Allow the engine to cool before lawn tractor. -1 To wing the lawn tractor behind another push another vehicle can damage the lawn tractor.
TOWING Trailer Safety Avoid sudden starts and stops while towing. The additional weight of the trailer or attachment could cause loss of control resulting in an accident. Never allow anyone to ride in the trailer. Failure to use the proper type of trailer hitch could cause the tractor to overturn resulting in severe personal injury. The weight of a trail& increases stopping distances; use extra care, especially when operating on a slope.

7. MAINTENANCE THE IMPORTANCE OF MAINTENANCE Good maintenance is essential for safe, economical, It will also help reduce air pollution. and trouble-free operation. Improper maintenance, or failure to correct a problem before operation, cause a malfunction in which you can be seriously hurt or killed. Always follow the inspection ules in this owner’s manual.
MAINTENANCE SAFETY Some of the most important warn you ofeveryconceivable Only you can decide whether safety precautions follow. However, we cannot hazard thatcan arise in performing maintenance. or not you should perform a given task. Failure to properly follow maintenance you to be seriously hurt or killed. Always follow the procedures instructions and precautions and precautions in the owner’s can cause manual.
EMISSION CONTROL SYSTEM Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, undercertain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic. Honda utilizes lean carburetor settings and other systems to reduce sions of carbon monoxide, oxides of nitrogen, and hydrocarbons. The U.S.
Replacement Parts The emission control systems on your Honda engine were designed, built, and certified to conform with EPA and California emission regulations. We recommend the use of genuine Honda parts whenever you have maintenance done. These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance.
