Tractor Mounted String Trimmer

Tractor Mounted String Trimmer CROPS Weed Control 28-6-17 When a customer called the Kosch company looking for a machine that would trim around and under fence lines, along stone fences, and other hard-to-cut areas, company engineers went to work and came up with a new pto-powered string trimmer. It's designed to fit a Cat. I 3 pt. hitch on tractors up to 25 hp. The pto drives a gearbox that speeds up the 540 pto up to over 1,000 rpms. The gearbox's shaft belt drives the string trimmer spindle, spinning it at more than 3,000 rpm's. "The unit flexes up and down so when you come up against an object, such as a fence post or a rock, it'll work its way right around it," says Royce Campbell, an engineer. "It'll float both vertically and horizontally with the contour of the cutting surface," he notes. Campbell isn't aware of anything on the market like it. The four 12-in. long strings are threaded into the string plate. Strings are available in nylon, kevlar, or a material with metal flakes in it. The string is square, round or diamond shaped. "All that does is change the way it cuts a little bit. Some of them are a little more durable than others," he says. The string that has the metal flakes lasts longer. "The diameter of the string we use is .155 in dia." The trimmer sells for $1,295.
