10.OPERATING THE BOOM UNIT AND ATTACHED HEAD
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand the Safety and Operation Sections of this manual and the tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the unit without complete operating instructions.
To ensure safety to the operator, bystanders, and equipment and before starting any mowing operation. The operator must become familiar with the area to be mowed, and any obstacles and hazards contained within. Special attention should be paid to foreign debris, overhead obstructions, rough terrain, steep slopes,passersby and animals in the area.
Only operate the mower head from the tractor operator’s seat with the seatbelt securely fastened. Only operate a boom and equipped head on cabbed tractor that is equipped with a polycarbonate
Avoid operating in the reverse direction when possible. In situations where the boom and mower must be backed to access areas to be cut, make sure there are no persons or other foreign debris behind the tractor. When backing, operate the tractor at a much reduced ground speed to ensure complete control of the unit is maintained.
10.1 Operating Instructions
Engage the PTO shaft at low engine RPM and speed the engine up after blades are fully engaged. Never engage the PTO shaft at a high engine RPM. This could cause damage to the PTO shaft as well as the Speed Increaser and Pump. Always operate PTO at the recommended RPM when mowing. This is necessary to maintain proper blade speed and to produce a clean cut.
Proper ground speed for cutting will depend upon the height, type, and density of material to be cut. Normally, ground speed will range from 2 to 5 mph. Tall dense material should be cut at low speed while thin medium height material can be cut at a faster ground speed.
Always run the Mower at the highest position which will enable you to obtain the desired cutting results. Allowing the blades to cut into the ground will cause wear and undue strain on the mower frame and mower components.
If you are mowing in conditions of heavy growth or rough ground where the blades cut into the ground and the tractor engine slows down, do not slip the clutch to allow the engine to speed up and engage the clutch again. This procedure exerts tremendous strain on Mower components. Always disengage the PTO and move forward or backwards until the machine is clear.
This mower is designed with free swinging blades. This feature reduces the amount of shock transmitted to other components. Always make sure the blades can swing freely on the blade bar.
When cutting foliage and fine shredding is desired, run the mower level or slightly lower in the rear so as to keep the material in the mower until it is shredded. This will require more power but will shred better. When cutting heavy foliage and fine shredding is not desired, raise the rear of the mower. This will allow the high volume of material to be discharged and requires much less power.
Do not ride the clutch on the tractor. Mow in the appropriate gears to give the correct ground speed.
