ProTed™ tedders feature a heavy-duty, one-piece, boxed metal frame that has a single welded seam. Unlike other designs, the ProTed Series has modular gearboxes that do not serve as part of the frame. Instead, durability is enhanced as the gearboxes are bolted to the mainframe to ensure that no additional strain on the frame occurs. To provide you with maximum reliability, these gearboxes feature crown and pinion drives positioned in one housing. Large drive shafts and double U-joints allow power to be smoothly transferred through the frame so that each rotor will easily follow the contours of your fields. The hexagonal driveshaft profile eliminates keys and keyways, which can weaken the shaft or cause failure under heavy crop loads.
