I1. SLOPE OPERATION • Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it. • Mow up and down slopes, not across. • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
• • • • Removegas-poweredequipmentfrom the truck or trailer and refuel it on the ground. If this is not possible,then refuelsuch equipment with a portable container, rather than from a gasoline dispenser nozzle. Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device. If fuel is spilled on clothing, change clothing immediately. Never overfill fuel tank. Replace gas cap and tighten securely.

We recommend standard safety glasses or a wide vision safety mask worn over spectacles. HOW TO USE YOUR TRACTOR TO SET PARKING • Never use choke to stop engine.
The cutting height range is approximately 1-1/2" to 4-1/2". The heights are measuredfrom the ground to the bladetip with the engine not running. These heightsare approximateand may vary dependingupon soil conditions, height of grassand types of grassbeing mowed. • The averagelawn should be cut to approximately2-1/2 inchesduring the cool season and to over 3 inchesduring hot months. For healthierand better lookinglawns, mowoften and after moderategrowth.
USING THE SYSTEM 1. 2. 3. 4. 5. REVERSE OPERATION Transmission Engaged Move motion control lever to neutral (N) position. With engine running, turn ignition key counterclockwise to ROS "ON" position. Look down and behind before backing. Slowly move motion control lever to reverse (R) position to start movement. When use of the ROS is no longer needed, turn the ignition key clockwise to engine "ON" position.
_,CAUTION: Wipe off any spilled oil or fuel. Do not store,spill or use gasoline near an open flame. IMPORTANT:When operatingin temperatures below32°F(0°C),use fresh,clean winter grade gasoline to help insure good cold weather starting. CAUTION: Alcohol blendedfuels (called gasoholor using ethanol or methanol)can attractmoisturewhich leads to separation and formationof acids duringstorage. Acidic gas can damagethe fuel system of an enginewhile in storage.
PURGE TRANSMISSION ,_CAUTION: Never engage MOWING or dis- engage freewheel lever while the engine is running. To ensure proper operation and performance, it is recommended that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have developed during shipping of your tractor.

TRACTOR Always observe safety rules when forming any maintenance. BRAKE OPERATION CHECK REVERSE SYSTEM per- section of this manual). • Maintain proper air pressure in all tires (See "PRODUCT SPECIFICATIONS" section of this manual). • Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber. • Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.
• To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.) NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not. • Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position.
