OPERATION
Tilling Depth Adjustment
The drag bar controls how far the tines dig into the ground. When tilling
hard packed ground, the tiller can jump forward if the drag bar is not
low enough. For initial adjustment, adjust the drag bar in a position that
is lower than expected and then slowly raise it until the desired setting
is achieved. Make sure there are no objects or bystanders in front of the
tiller in case it jumps forward.
To adjust the tilling depth, remove the locking bolt and slide the drag
bar up or down.
