Caution
Personal injury may occur if only one person tries
to pivot the cutting unit up or down.
Use at least one other person to assist in lifting
or lowering the unit.
Always use proper lifting techniques and hold
the unit securely when pivoting it up or down.
To Pivot the Cutting Unit Down into the
Operating Position
1. With the help of an assistant, hold the unit upright,
remove the klik pin securing the link end and remove
link end from the weldment.
2. Pivot (tilt) the cutting unit downward.
3. Sit on seat, start engine and lower the cutting unit so
castor wheels just clear the floor.
4. Remove the height-of-cut pin from the right castor
wheel arm. Insert it and the left height-of-cut pin in the
proper height-of-cut holes in the castor arms and cutting
unit.

Blade Bolt Torque

Check blade bolt torque daily or after blade strikes a solid
object. However, if solid object causes blade to be damaged
or bent to a degree it is unusable, replace it; refer to
Removing Cutting Unit Blade, below.
1. Raise cutting units to transport position, engage parking
brake, shut engine off and remove key from ignition
switch.
2. Using a torque wrench and rag or thickly padded glove
to hold blade, torque blade bolts on all cutting units to
