Setting the Gauge Wheel

The gauge wheel can be positioned for three different application depths: regular, mid-range and shallow. Seedbed conditions will dictate the optimum setting for maintaining the most consistent fertilizer placement. The regular setting should be used for most conditions except when inadequate opener penetration or rocks pose a problem.

Depending upon soil conditions, the shallow setting will apply fertilizer up to approximately 50 mm (2 in.) depth. The mid-range setting will allow up to approximately 75 mm (3 in.) depth. The regular setting will allow up to approximately 100 mm (4 in.) depth.

NOTE: The concentration pattern of fertilizer will vary with soil conditions. Dry, loose soil will fill in somewhat, causing the fertilizer to be distributed in a narrow vertical band. Moist or firm soil will create a more well-defined furrow, causing the fertilizer to be concentrated more near the bottom of the opener furrow.

To adjust dimension (A), position depth adjustment bolt (B) in the proper hole.

For maximum depth, locate adjustment bolt in hole (C); for mid-range depth, locate bolt in hole (G); for minimum depth, locate bolt in hole (D).

For most conditions, wheel should be bolted to lever arm at (E).

NOTE: On left-hand openers, bolt (E) has left-hand threads; on right-hand opener, bolt (E) has right-hand threads. Bolts should tighten in rotation of wheel.
