BLADE REMOVAL
Never work under the implement, or any lifted component unless the imple-
ment is securely supported or blocked to prevent sudden or inadvertant falling
which can cause serious injury or death.
The replacement of the blades must be done using maximum caution, and always with the tractor shut off and the dri-
veshaft disconnected from the tractor. Raise the mower body to the maximum height possible with the tractor power-
lift so as to allow you to work properly on the underneath part of the mower.
1. Support the raised machine with suitable supports under the mower frame and support the raised machine with a
suitable over head hoist capable of supporting the implements weight.
2. Remove the Blade Bolt, Cup Washer, Blade and Blade Washer.
