Positive Cultivator Depth Control

Positive Cultivator Depth Control CULTIVATORS Cultivators (58C) 19-5-31 Maintaining even depth control across the entire width of his big Ezee-On cultivator was a problem for Wayne Williams, Souris, Manitoba, until he came up with a relatively simple solution to solve the problem. He says the idea may well work with other cultivators and other types of equipment. The problem was that the cultivator - which Williams uses to "air seed" small grains - uses just one large master cylinder to lift and lower the cultivator. The master cylinder attaches to a main rocker shaft at the center of the machine, and the main shaft in turn operates the rocker shafts on the wings through a mechanical linkage. The problem was that depth on the wings often did not match depth on the center section due to flexing and "play" that would develop in the rockershafts, particularly under heavy draft conditions. So Williams simply built two small frames out of 4-in. sq. tubing to mount just behind the linkages on the rockershafts on either wing. Each well-braced frame is fitted with a large 1 7/8-in. dia. bolt that screws into the brackets from behind. "They're positioned so when the cultivator is lowered to working position, the bolt can be adjusted to butt up against the linkage arm of the rockershaft," notes Williams. To change depth, he merely backs the stop bolt off, establishes proper depth on a loose well-worked piece of ground, then butts the stop bolt up against the rockershaft arm and tightens a jam nut to hold it in place. "After that, there's no physical way that the working depth of the cultivator can vary from one end to the other. We've had very uniform emergence of our crops since adding this depth stop to the cultivator," says Williams. Contact: FARM SHOW Followup, K.
