30” row spacing (60”/120”)
1. Attach the sprayer to tractor and engage tractor parking brake.
2. Place stop wedges in front of, and behind RH wheel. Jack up LH
wheel, support and secure sprayer body.
3. Remove 8 of the 10 wheel nuts, leaving 2 wheel nuts opposite
each other to secure the inner wheel.

sprayers with shorter stud bolts.
4. Attach dual spacer (B) or (C) to inner rim using the 8 wheel nuts (D)

the center of inside tire to center of outside tire is 22” or 30”. Wheels may need to be reversed and exchanged.
