Header Height Control For Deere IH Cornheads
"Every year combines keep increasing ground speed in corn because the machines have so much capacity. At speeds of up to 5 1/2 mph it's difficult to always keep headers level. Our new header height control is a simple and economical way to get instant, hands-off control," says Dan FitzSimmons, inventor of a new height control system for Deere and Case/IH combines (soon to fit other models as well) that plugs into your combine's existing hydraulics.
The new system, manufactured and marketed by May-Wes Mfg., is designed to fit Deere and IH combines that are equipped with controls for hydraulically leveled bean and flex heads. The May-Wes system makes use of the fittings and controls for those heads. It consists of "feelers" that mount at about the mid-point of the underside of the snouts (three per 8-row head). The curved, plastic-coated feelers, which slide along the ground, are connected by cables to a spring-loaded rock shaft that mounts at the back of the cornhead. The rockshaft is connected by linkage to the hydraulic header controls.
"Unlike other, more expensive systems on the market that require a different valve and controller, this height control system plugs right into the combine's existing hydraulics, allowing the operator to dial in the proper height and keep the head in the same position regardless of the terrain," says FitzSimmons, who's service manager at a southern Minnesota Case/IH dealer-ship.
The height control system was field-tested last fall,on two combines. "It makes your cornhead float like a bean head. Works great, especially when working at night or in rocky or badly rutted fields," says FitzSimmons.
Three feelers are installed on an 8-row head, two on a 6-row head. They operate independently so any one of them can raise the entire head.
The new control system fits any Case/IH combine since 1981 with flex head height control, and any Deere combine with "Dialamatic" controls. It's available for 6 and 8 row heads. May-Wes plans to also develop it for 12-row heads, and for other combine makes. Sells for $1,000 to $1,250, depending on model and size cornhead.
