Abstract: A composting system with a digestion chamber, an auger shaft with at least one mixing vane, and a power unit. The power unit can be hydraulic and can also power a shredding unit and an input conveyor system. A barrier wall can be interposed between those elements and the digestion chamber. The digestion chamber can be divided into subchambers, and sequentially lower apertures can promote a progression of organic material. A malfunction sensor can sense a malfunction of the auger shaft, the shredding unit, or another component. A malfunction report can be provided, including to a remote receiver. The report can include a determined location of the composting system and can be directed to a selected receiver based on the malfunction. Fluids, including gasses and liquids, can be introduced by a supply source in combination with apertures along the auger shaft and/or a mixing vane.

Abstract: A tractor transmission includes first and second hydraulically actuated disc clutches adapted to drivably connect an input shaft, which is clutched by a friction clutch to an engine, to a first and second sleeve shafts. The countershaft and the sleeve shafts support gear-pinion pairs that produce four speed ratios. The range box includes gearing mounted on an output shaft, a countershaft, and the input shaft to drive the output shaft at a slower speed than that of the countershaft when the low range is selected, to drive the output shaft in the opposite direction to its forward drive direction when reverse operation is selected, and to directly connect the countershaft to the output shaft when the high speed range is selected.
