frontier disk harrow

A frontier disk harrow is a farm implement used for tilling soil in preparation for planting crops. It consists of a series of concave disks that are arranged on a common axis and are designed to cut into the soil, breaking up clumps and creating a smooth, level seedbed.

The frontier disk harrow is usually attached to a tractor and is pulled behind it, with the disks rotating as the implement moves forward. The depth of the disks can be adjusted to suit the conditions of the soil, and the angle of the disks can also be adjusted to control the amount of soil disturbance.

The frontier disk harrow is an important tool for farmers, as it helps to prepare the soil for planting and promotes better seed-to-soil contact, which can lead to higher yields. It is also used for weed control and for incorporating fertilizer or other soil amendments into the soil.
