Mowing Instructions
Operating Instructions
Proper servicing and adjustments are the key to the long life of any machine. With careful and systematic
inspection of the mower, costly maintenance, time and repair can be avoided.
Before beginning to mow, the following inspection should be performed:
Leveling the Mower
NOTE: Tractor and mower should be on level ground.
Leveling can be adjusted at the tractor’s 3-point arms and center link.
Cutting Height Adjustment
The machines cutting height depends upon the position of the rear roller.
3-Point Hitch Adjustments
The 3-point hitch system on this mower has been designed for front to back flotation when mowing on uneven terrain. Adjust tractor’s top center link to place the upper hitch pin vertically above or slightly behind the lower hitch pins. The mower should be run with the back 15 degrees lower than the front.
The hitch can also be adjusted from side to side by turning the adjustment handle. Turn handle until you have achieved your desired location.
|
|
CAUTION Engage parking brake, shut off tractor, remove key and disengage PTO before making any height adjustments! |
Belt Tension
|
|
CAUTION Belt drive system under spring tension; use care to avoid bodily harm! |
The Belt tension should be checked after the first 20 hours of use. And then every 40 hours of use.
|
|
CAUTION Excessive tension on the belt may lead to premature failure of belt and drive components. Excessive tension on the belt may also lead to a safety hazard to the operator or bystanders. |
Maintenance
Proper servicing and adjustment is the key to the long life of any farm implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.
|
|
CAUTION For safety reasons, each maintenance operation must be performed with tractor PTO disengaged, mower lowered completely to ground and tractor engine shut off with ignition key removed. After using the mower for several hours, check all bolts to be sure they are tight and check drive belt tension.. |
Knife Replacement
|
|
IMPORTANT Make sure that the knife is the same length as the others on the mower. This will keep the rotor rotation balanced. |
V-Belt Installation
|
|
CAUTION Belt drive system under spring tension; use care to avoid bodily harm! |
Storage
At the end of the working season or when the mower will not be used for a long period, it is good practice to clean off any dirt or grease that may have accumulated on the mower and any of moving parts.
