•Familiarize yourself with the operations of all the instruments and controls.

•Before starting the engine or beginning operation, be familiar with the controls. The operator should be in the operator’s seat. The PTO switch must be in the disengaged position, the parking brake engaged, and the RH and LH drive control levers moved fully outward in the neutral position.

•Keep all shields in place. Keep away from moving parts.

•NO RIDERS! Keep all people and pets a safe distance away. Look behind and down to both sides of the tractor before and while backing up.

•DO NOT direct the mower discharge at people.

•Avoid slopes where possible. Never operate on slopes greater than 15°. Slopes with a greater incline present dangerous operating conditions. Tractors can be rolled over.

•Before leaving the operator’s seat: Shut off the PTO, move the RH and LH drive control levers fully outward in the neutral position, engage the parking brake, shut off the engine and remove the ignition key. Wait for all movement to stop before servicing or cleaning.

•Operate the drive control levers smoothly and avoid any sudden movements of the levers when starting and stopping. Keep a firm grip on the control levers; do not allow the levers to return to neutral on their own.

•Be careful when operating near roadways. Stop the tractor motion and wait for vehicles to pass before operating along the road.

•Do not operate the tractor with the mower deck removed. Removal of the deck will change the balance of the tractor, and could contribute to a tractor rollover.

•Avoid operation on traction surfaces that are unstable; use extreme caution if the surface is slippery.
