Gauge Wheel Adjustments

The planter rows on the drill are adjusted by raising or

lowering the gauge wheels.

Raise the drill out of the ground and loosen the jam nut

located near the bottom clevis of the gauge wheel turn-

buckle, Figure 4-1. This turnbuckle is threaded to

alloweasy gauge wheel adjustment. By lengthening the

turnbuckle the gauge wheel is lowered, also lowering the

openers. By shortening the turnbuckle the gauge wheel

is raised, also raising the openers. After adjusting, be

sure the turnbuckle on both gauge wheel arms have the

same pin center dimensions.

Your 3-Point Drill is designed to run level to the ground

when in planting position. Minor adjustments may be re-

quired to achieve the desired bean placement. After any

gauge wheel adjustments have been made, use the top

link to set box and frame level to the ground.
