nect driveline, raise mower, securely block

Figure 14. Blocking Method
Do not work underneath mower unless it is properly
attached to the tractor and blocked securely. When
properly attached, the unit will be anchored to
minimize front to rear movement.
Raise mower completely, set tractor brakes, turn
engine off, remove key, block tractor wheels front and
rear, and disconnect mower driveline from tractor.
The only approved blocking device for this mower is
a jackstand with a load ratingof 1000 pounds or more.
Install one jackstand under each corner of the mower
(four total), before working underneath this unit.
When blocking, you must consider overall stability of
the unit. Just blocking under the unit will not ensure
your safety. The working surface must be level and
solid to support the loaded weight of the jackstands.
Test jackstands stability before working under any
portion of the mower.
