Abstract
A row crop cultivator particularly adapted for ridge-hill and minimum tillage farming conditions. The cultivator carries a number of tools including spaced hilling disks, a coulter wheel and a sweep for effectively pitching soil and cutting crop residues and weeds between the planted rows. A gauge wheel assembly is provided for controlling the depth of penetration of the tools into the soil. The gauge wheel assembly includes a pair of elongated arms pivotally connected between a pair of parallel plates on the cultivator frame. Series of vertically spaced adjustment holes are formed in the plates and a pin member is selectively insertable in any aligned pair of holes to limit pivotal movement of the gauge wheel arms the elevation of the gauge wheel relative to the frame. The gauge wheel adjustments are easily made by hand in the field without the use of tools.
