Safety Rules & Information Operating Safety Congratulations on purchasing a superior-quality piece of lawn and garden equipment. Our products are designed and manufactured to meet or exceed all industry standards for safety. Power equipment is only as safe as the operator. If it is misused, or not properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you. Use common sense, and think through what you are doing.
Safety Rules and Information Slope Operation You could be seriously injured or even killed if you use this unit on too steep an incline. Using the unit on a slope that is too steep or where you don’t have adequate traction can cause you to lose control or roll over. A good rule of thumb is to not operate on any slope you cannot back up (in 2-wheel drive mode). You should not operate on inclines with a slope greater than a 3.5 foot rise over a 20 foot length.
Safety Rules & Information Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed. GENERAL OPERATION 16. Use extra care when loading or unloading the unit into a trailer or truck. 17.
Safety Rules and Information SLOPE OPERATION WARNING Slopes are a major factor related to loss-of-control and tipover 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 operate on it. Control of a walk-behind or ride-on machine sliding on a slope will not be regained by the application of the brake.
Safety Rules & Information SERVICE AND MAINTENANCE Safe Handling of Gasoline 1. Extinguish all cigarettes, cigars, pipes, and other sources of ignition. 2. Use only approved gasoline containers. 3. Never remove the gas cap or add fuel with the engine running. Allow the engine to cool before refueling. 4. Never fuel the machine indoors. 5. Never store the machine or fuel container where there is an open flame, spark, or pilot light such as near a water heater or other appliance. 6.

Features & Controls 38, 44 & 50” Models 12V 40” Models Figure 1. Controls Control Functions The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section. Headlights Throttle Control The throttle controls engine speed.
Features & Controls Cutting Height Fine Tuning Adjustment (40” Mower Decks Only) Reverse Mowing Option (RMO) The Reverse Mowing Option allows for mowing (or use of other PTO driven attachments) while traveling in reverse. If you choose to mow in reverse, turn the RMO key after the PTO is engaged. The L.E.D. light will illuminate, and the operator can then mow in reverse. Each time the PTO is engaged the RMO needs to be reactivated if desired.
Features & Controls Parking Brake Function Applying the Parking Brake - See Figure 2. To lock the parking brake, release the ground speed pedals (A), fully depress the brake pedal (B), pull UP on the parking brake knob (C), and then release brake pedal. E B Releasing the Parking Brake - See Figure 2. To release the parking brake, depress the brake pedal (B). A Cruise Control Operation C D TO ENGAGE: 1.

Operating the Tractor General Operating Safety Safety Interlock System Tests Be sure to read all information in the Safety and Operation sections before attempting to operate this unit. Become familiar with all of the controls and how to stop the unit. This unit is equipped with safety interlock switches and other safety devices. These safety systems are present for your safety: do not attempt to bypass safety switches, and never tamper with safety devices. Check their operation regularly.
Operating the Tractor Stopping the Tractor & Engine Mowing in Reverse 1. Return the ground speed control(s) to neutral. 2. Disengage the PTO and wait for all moving parts to stop. 3. Briggs & Stratton Models: Move the throttle control to SLOW position and turn the ignition key to OFF. Remove the key. Kohler Models: Move the throttle control to FAST position and turn the ignition key to OFF. Remove the key. If an operator chooses to mow in reverse, the RMO system can be used.
Operating the Tractor Mower Deck Removal & Installation D WARNING C Engage parking brake, disengage PTO, stop engine and remove key before attempting to install or remove the mower. B D Removing the Mower Deck A Later Models 1. Park tractor on a hard, level surface such as a concrete floor. Turn off PTO switch and engine, remove the key and apply parking brake. 2. Place mower in the lowest cutting position using the mower height adjuster (B, Figure . D C D 3.
Operating the Tractor B A A B Figure 6. Mower Hitch A. Tractor Hitch Brackets B. Spring-Loaded Lever Figure 7. Raising & Lowering Mower A. Mower Lift Lever B. Mower Height Adjuster Adjusting Mower Cutting Height 38”, 44”, & 50” Mower Decks B The mower lift lever (A, Figure 7) is used to lower the deck to cutting position of raise the deck to transport position. To lower the deck, pull back slightly on the mower lift lever (A), push it to the left and slide it down.
Operating the Tractor Using a Mulching Mower (40” Mower Only) B Benefits of Proper Mulching Mulching consists of a mower deck which cuts and recuts clippings into tiny particles and then blows them down into the lawn. These tiny particles decompose rapidly into by-products that your lawn can use. Under proper conditions your mulching mower virtually eliminate noticeable clippings on the lawn surface.
Operating the Tractor Attaching a Trailer The maximum horizontal drawbar force allowed is 280 Newton. The maximum vertical drawbar force is 160 Newton. This equates to a 250 lbs (113 kg) trailer on a 10 degree hill. Secure the trailer with an appropriately sized clevis pin (A, Figure 11) and clip (B). A WARNING Never store the unit (with fuel) in an enclosed, poorly ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion.
Regular Maintenance MAINTENANCE SCHEDULE & PROCEDURES The following schedule should be followed for normal care of your tractor and mower.
Regular Maintenance Safety Interlock System Check Battery Maintenance Service Interval: Every Fall & Spring WARNING Check the function of the safety interlock system using the test procedure found on page 13 of this manual.
