• Read or review the operator's manual to familiarize yourself with the machine.
• Learn the location and use of controls, gauges, and dials for the tractor.
• Familiarize yourself with speeds, slope capabilities, braking and steering characteristics, and tractor-mower clearances.
• Be sure the tractor is equipped with a roll-over protective structure (ROPS) and a seat belt. If not, have it retrofitted for one.
• Check that the power take off, mower input driveline, drive belts, chains, and gears are all properly guarded. Repair or replace if necessary.
• Check the discharge chute to see that it is present and pointed downward.
• Fill the fuel tank out of doors with the engine stopped and cool. Do not smoke while filling.
• If you will be driving on public roads be sure the slow moving vehicle (SMV) emblem is in place. Check that the warning lights are present and operating.
• Check overhead clearance of electrical wires and other obstructions, especially if you are using a wing-type, boom-type, or flail mower.
• Inspect the work area for debris, ditches, potholes, stumps, irrigation valves, etc. Clear removable items and mark the others.

• Be sure your hands and shoes are clean and dry before mounting the tractor to prevent slipping. Use the steps and handbars.
• Do not allow any riders -- especially children.
• Adjust the seat, fasten the seat belt, set the parking brake, place shift lever in neutral or park, and disengage the pto before cranking the engine.
• Raise the mower high and use low rpm before engaging power to the unit.
• Use a ground speed based on length and density of material being cut -- normally between 2-5 mph.
• Mow very tall grass twice at 90-degree angles if possible.
• Mow up and down slopes with rear-mount, pull-type, and wing-type mowers.
• Mow across slopes with side-mount, offset, and sicklebar mowers.
• Look behind you before backing.

• When finished or stopping, disengage the pto, place shift in neutral or park, set parking brake, turn engine off, and wait for all movement to stop before dismounting.
• Remove the key if leaving the tractor for any length of time.
• Always block the mower if working under it for any reason.
