Page 6: General Safety Instructions And Practices
SAFETY General Safety Instructions and Practices 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.
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.
Page 9 SAFETY Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.
Page 10 SAFETY Always read carefully and comply fully with the manufacturer’s instructions when handling oil, solvents, cleansers, and any other chemical agent. (SG-22) Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health. (SG-23) Never allow children to play on or around Tractor or Implement.
Page 11 SAFETY Relieve hydraulic pressure prior to doing any maintenance or repair work on the Implement. Place the Implement on the ground or securely blocked up, disengage the PTO, and turn off the tractor engine. Push and pull the Remote Cylinder lever in and out several times prior to starting any maintenance or repair work.

Page 37: Driving The Tractor And Implement
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.
Page 38: Starting The Tractor
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.
Page 39: Driving The Tractor And Implement
OPERATION 9. DRIVING THE TRACTOR AND IMPLEMENT Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor and unit. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent the operator from stopping quickly during an emergency.
Page 40: Operating The Blade
OPERATION 10.1 Operating the Blade When operating the Box Scraper, a reasonable degree of care should be taken to avoid large obstacles that would create undue loads on both the blades and linkage which could result in damage to your scraper. Level the box blade from side to side and front to rear using adjustments on the tractor’s 3-point lift.
Page 41: Shutting Down The Implement
OPERATION Moving snow with the blade in backfill position is a very delicate operation and should be performed with extreme care and very slow speed. It is very easy to hit objects hidden in snow, or hit a snow bank that is too much material for your blade to move.
Page 42: Transporting The Tractor And Implement
OPERATION • Check the unit for worn and damaged parts. Perform repairs and make replacements immediately so that the unit will be ready for use at the start of the next season. • Store the unit in a clean, dry place resting securely on the level ground. •...
Page 43 OPERATION Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.
Page 44: Transporting On Public Roadways
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 45 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.
Page 46: Hauling The Tractor And Implement
OPERATION 14.2 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. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through.
