Guidance System

Guidance SystemThis new self-guiding system for row crops consists of a tilted rubber tire gauge wheel and a companion furrowing shoe. The 8 inch diameter wheel, mounted on the spindle at a 33 degree angle, travels directly ahead of it. Two pairs are used on a 4-row and three pairs on a 6-row 30 inch row spacing cultivator. Two are mounted on either side opposite on the front bar next to the guest row with the tilt facing to the center and two are on the rear bar in the same fashion. For 6-row cultivation the other two are placed in line with the tractor tires in the same fashion as the others.

Most farmers who grow row crops -- whether corn, soybeans, cotton, or vegetables -- can easily adapt this system to their existing 3-point cultivator precisely on the row , it allows him to travel at speeds faster that normal, even when plants are small. The system readily adapts to all types of row crop planting -- whether on beds, ridges, or level ground.

When you come to the field with the 3-point cultivator, you remove the blocks to give the cultivator freedom to swing freely on the 3-point. You then adjust the guide wheels and companion furrowing shoes so the cultivator moves strait down the rows as it's pulled forward. If it tends to veer to the left, you would move the gauge wheels or the furrowers to the right to pull it back so it travels dead center down the rows. Once adjusted, the tilted guide wheels on the side of the cultivator, traveling in grooves made by the companion furrowers mounted just ahead. of them, hold the cultivator in alignment independent of the tractor's exact travel path -- within the "swinging room" distance of the 3- point hitch.

The guidance system is easier to understand if you think of the furrows and guide wheels working together to lay a pair of railroad tracks parallel to the crop rows. The cultivator, riding on these rails, is self-guiding, steering itself with greater accuracy -- even in new emerged crops planted in narrow rows.

The guidance system leaves small tracks in the field. If you want to level the ground between the rows, tools can be added on the rear to eliminate the tracks.

A pull type cultivator usually has wheels to raise it up when turning. Some have runners which cause considerable drag and even wear out. Guide wheels may be mounted where several of the runners are removed to give you precision work with less drag and wear. We all know that fuel is expensive, and the less drag you have the less fuel you use -- a tractor pulling only the tools which are working the soil, is the most efficient.

A pair of tilted guide wheels comes complete with foam-filled rubber tires, standards (including hubs and bearings which are heavy-duty and protected by dust shields.), furrowers, and brackets permit the complete unit to be mounted on a tool bar.

Guidance System

Guide wheels are mounted outside the tractor row because when the soil is wet, the weight of the tractor lowers the depth of the furrow. With the wheels mounted outside the tractor row, the cultivator always stays at the same depth. If using only 2 bars on a 6 or 8 row framework, 1 pair on each side works well.
