10. Remove rear walkboard and right and left mounting

brackets. Using existing screws, install new
extended walkboard mounts to the rear of the drill
frame. Reattach walkboard to new extended mounts.

NOTE

For 30’ drills – If the drill has the optional dry fertilizer
attachment, the grass seed bracket and bearing will not

bearing assembly. Loosen the rear mounting
screws, then lift up and remove the shield and
screws.
