IMPORTANT: This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death. • Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place. • Slow down before turning. • Never leave a running machine unattended.
DO: • Mow up and down slopes, not across. • Remove obstacles such as rocks, tree limbs, etc. • Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles. • Use slow speed. Choose a low gear so that you will not have to stop or shift while on the slope. • Follow the manufacturer's recommendations for wheel weights or counterweights to improve stability. • Use extra care with grass catchers or other attachments. These can change the stability of the machine.
• Remove obstacles such as rocks, tree limbs, etc. • Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles. • Use slow speed. Choose a low gear so that you will not have to stop or shift while on the slope. • Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope. • If machine stops while going uphill, disengage blades, shift into reverse and back down slowly.

The operation of any tractor can result in foreign objects thrown into the I eyes, which can result in severe eye damage. Always wear safety glasses I or eye shields while operating your tractor or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectac es. HOW TO USE YOUR TRACTOR IMPORTANT: Leaving the ignition switch in any position other than "STOP" will cause the battery to discharge and go dead.
• The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mow often and after moderate growth. • For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to desired height. TO ADJUST _CAUTION: Do not operate the mower without either the entire grass catcher, on mowers so equipped, or the deflector shield in place.
Transmission Transmission Engaged _CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. IMPORTANT: When operating in temperatures below 32°F(0°C), use fresh, clean winter grade gasoline to help insure good cold weather starting. CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.
WARMWEATHERSTARTING(50° F and above) 8. When engine starts, slowly push choke control in untilthe enginebegins to run smoothly.If the enginestarts to run roughly,pull the chokecontrolout slightly for a few seconds and then continueto push the control in slowly. • The attachmentsand grounddrive can now be used.If the engine does not acceptthe load, restartthe engine and allow it to warm up for one minuteusing the chokeas describedabove. COLD WEATHERSTARTING(50° F and below) 8.
MOWING TIPS • Mower should be properly leveled for best mowing performance. See "TO LEVEL MOWER HOUSING" in the Service and Adjustments section of this manual. • The left hand side of mower should be used for trimming. • Drive so that clippings are discharged onto the area that has already been cut. Have the cut area to the right of the tractor. This will result in a more even distribution of clippings and more uniform cutting.

TRACTOR IMPORTANT: To ensure proper assembly, center hole in blade must align with star on mandrel assembly. 4. Reassemble blade bolt, lock washer and flat washer in exact order as shown. 5. Tighten blade bolt securely (27-35 Ft. Lbs. torque). IMPORTANT: Blade bolt is heat treated. If bolt needs replacing, replace only with approve bolt shown in the Repair Parts. Always observe safety rules when performing any maintenance.
V-BELTS Check V-belts for deterioration and wear after 100 hours of operation and replace if necessary. The belts are not adjustable. Replace belts if they begin to slip from wear. BATTERY Your tractor has a battery charging system which is sufficient for normal use. However, periodic charging of the battery with an automotive charger will extend its life. • Keep battery and terminals clean. • Keep battery bolts tight. • Keep small vent holes open. • Recharge at 6-10 amperes for 1 hour.
IMPORTANT: Petroleum solvents, such as kerosene, are not to be used to clean the cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge. Oil Drain Valve Closed and Locked --------Position Drain Tube 3. Unlock drain valve by pushing inward slightly and turning counterclockwise. 4.
