SAFETY RULES 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.
SAFETY RULES • 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. • Keep all movement on the slopes slow and gradual.
SAFETY RULES • 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.

✓CHECKLIST CHECK TIRE PRESSURE The tires on your tractor were overinflated at the factory for shipping purposes. Correct tire pressure is important for best cutting performance. • Reduce tire pressure to PSI shown in “PRODUCT SPECIFICATIONS” section of this manual. Before you operate your new tractor, we wish to assure that you receive the best performance and satisfaction from this Quality Product. Please review the following checklist: ✓ All assembly instructions have been completed.
OPERATION These symbols may appear on your tractor or in literature supplied with the product. Learn and understand their meaning.
KNOW YOUR TRACTOR READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR TRACTOR Compare the illustrations with your tractor to familiarize yourself with the locations of various controls and adjustments. Save this manual for future reference.
The operation of any tractor can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your tractor or performing any adjustments or repairs. We recommend a wide vision safety mask over spectacles or standard safety glasses. • Never use choke to stop engine. 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. • If stopping is absolutely necessary, push clutch/brake pedal quickly to brake position and engage parking brake. • Move gearshift lever to 1st gear.
ADD GASOLINE • Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.
MOWING TIPS • Tire chains cannot be used when the mower housing is attached to tractor. • 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.
