摘要： An improved mounting arrangement for a knife to a disc for use on a rotary disc cutter that eliminates the need for a threaded connector and the associated nut is disclosed. It also provides a positive retention method on the top side of the disc. In addition, it provides a method of removing the knife from the disc without the use of wrenches, simply requiring a tool for prying, such as a screw driver. A further feature is a low profile retainer that does not need to be protected by a wear protector.

摘要： A suspension system for a tractor-drawn mower used for crops for agricultural purposes is made up of parallel links, connected at a first end to a frame and to a mowing unit at a second end. A torsion spring assembly, similar to that used for torsion axles, is used to bear a portion of the weight of the mowing unit when the mowing unit is in a lower, mowing position. All torsional stress is removed from the torsion spring when the mowing unit is in a transport position. During mowing, the weight of the mowing unit is divided up between the torsion spring and the surface of the ground. The ratio of the weight supported by the ground to that supported by the torsion spring is adjustable by an operator.
