SAFETY Safety Messages A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed, will help protect the operator and bystanders from injury or death.
Page 7
SAFETY Never operate the Tractor or Implement until you have read and completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and Implement. Learn how to stop the tractor engine suddenly in an emergency.
Page 8
SAFETY Never allow children to operate, ride on, or come close to the Tractor or Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in proper operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily.

SAFETY PROLONGED EXPOSURE LOUD NOISE CAUSE PERMANENT HEARING LOSS! Tractors with or without an Implement attached can often be noisy enough to cause permanent hearing loss. We recommend that you always wear hearing protection if the noise in the Operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss.
Page 10
SAFETY Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order.
Page 11
SAFETY Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over.

OPERATION 8. DRIVING THE TRACTOR AND IMPLEMENT Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the implement and the tractor operating controls are set for safe transport.
OPERATION 8.1 Starting the Tractor The procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO is disengaged before starting the tractor.
OPERATION 8.3 Driving the Tractor and Blade Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor and blade. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control.
OPERATION 9.1 Operating the Blade Only operate the blade from the tractor operator’s seat with the seatbelt securely fastened. The tractor must be equipped with a ROPS in the raised position or a ROPS cab. Ditching (V-Type Ditch) Rotate Moldboard to desired angle (right or left) and place Lock Pin in desired hole of Moldboard Rear Mount. Blade point should be centered close behind or slightly to outside of tractor tire.
OPERATION 9.2 Shutting Down the Implement Park the tractor on a level surface, place the transmission in park or neutral and apply the parking brake, lower the attached implement to the ground, shut down the engine, remove the key, and wait for all motion to come to a complete stop before exiting the tractor.
OPERATION 11. BLADE STORAGE Properly preparing and storing the blade at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service. The following are suggested storage procedures: • Thoroughly clean all debris off the blade to prevent damage from rotting grass and standing water.
OPERATION Before transporting the tractor on a public roadway or boarding a trailer for transport, the tractor brake pedals should be locked together. Locking the pedals ensures that both wheels brake simultaneously while stopping, especially when making an emergency stop. Use extreme caution and avoid hard applications of the tractor brakes when towing heavy loads at road speeds.
Page 51
OPERATION The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility.
OPERATION Reduce speed before turning or applying the brakes. Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023 12.2 Hauling the Tractor and Implement Before transporting a loaded tractor and implement, measure the height and width dimensions and gross weight of the complete loaded unit.
Page 53
OPERATION Arrange the chains so that when tightened, the chains pulling downward against themselves. Carefully tighten the securing chains or other fasteners using boomers or binders to apply maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension involved when released has the potential to inflict serious injury.
