Transmission for towed agricultural equipment

A two-speed transmission for towed agricultural equipment to a towing machine that is activated through a power take-off of the towing machine, comprising an input shaft that is activated by the towing machine, wherein a pinion is arranged on the input shaft entering into a transmission box, said pinion being activated by the input shaft and that by activating through a hypoid tooth or conical coupling a crown gear fixed onto an intermediate shaft, the intermediate shaft being arranged substantially orthogonal to the input shaft, on the intermediate shaft two gears are arranged with different dimensions, and wherein by means of a clutch or joint one of the two gears can be connected to the intermediate shaft, the gears of the intermediate shaft are respectively coupled with a gear arranged on an output shaft, and wherein in the connection of the gear of the intermediate shaft to the gear of the output shaft without a clutch at least one of the gears has a free wheel connection with its respective shaft onto which it is fixed, and the output shaft being arranged in the same plane as the input shaft and the output shaft can be connected at its two ends outside the transmission box with a shredding head or cutter.
