Deck Leveling & Height Adjustments
There are 4 primary adjustments that should be made
prior to actual field operations:
•
Deck Leveling From Left to Right
•
Deck Leveling From Front to Rear
•
Set tractor’s 3-Point hydraulic control stop at
this height.
•
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance, and
longer blade life. The following tools will be needed:
•
Pliable tape measure
•
Spirit or carpenters level
•
Open end or hex end wrench or socket set
•
Protective gloves
