Mount Knock Downs
On a drill with narrow row spacing, there is apt to be
insufficient clearance at rear rows for convenient
mounting. In that case, connect a hoist to, or install a jack
under the row unit. Release a rear row at a spring rod
pin, and fully lower it for knock down installation. You may
wish to leave all rear rows lowered for knock down
adjustment as well.

Crushing and Sharp Object Hazards:

and secure attachment or lifting point. Stand clear of moving
row unit. Opener blades are sharp. The row is heavy and could
