A gearbox containing two shafts connected internally causing the shafts to operate at different speeds. One shaft has a 21-spline female connection on one end with a 21-spline male connection on the other end. The other shaft has a 6-spline female connection on one end with a 6-spline male connection on the other end. The female end of one shaft can connect to the standard 1000-RPM power take-off shaft of a power unit. Alternatively, the female end of the other shaft can be connected to the standard 540-RPM power take-off shaft of a power unit. The output shafts operate at two different speeds; one at 540-RPM and the other at 1000-RPM. These output shafts connect to the standard 6-spline/21-spline female connection on driven equipment. By connecting the driven equipment to the matching spline shaft, the driven equipment will operate at the proper speed. It also provides capability to drive two units concurrently with one power unit. The most common use would be to connect the power take-off of farm or industrial power units to multi driven units or driven units with different RPM speed.
A portable gear arrangement comprising a first shaft, a second shaft, a power transmission mechanism connecting the shafts, the power transmission mechanism being at least one of a gear arrangement or a chain and sprocket arrangement, each of the shafts having an input end configured to be directly connected to a power unit and an output end configured to be directly connected to a driven device, wherein the gear arrangement being configured to provide a speed reduction when the input end of the first shaft is connected to the power unit and the output end of the second shaft is connected to the driven device, and the gear arrangement being configured to provide a speed increase when the input end of the second shaft is connected to the power unit and the output end of the first shaft is connected to the driven device.
A gear arrangement for agricultural machines comprising a first shaft, a second shaft, a power transmission mechanism connecting the shafts, the power transmission mechanism being at least one of a gear arrangement or chain and sprocket arrangement, each of the shafts having an input end configured to be directly connected to a power unit and an output end configured to be directly connected to a driven device, the input end of the first shaft having a 6-spline connector for attachment to the power unit, the input end of the second shaft having a 21 spline connector for attachment to the power unit, wherein the gear arrangement being configured to provide a speed increase when the input end of the first shaft is connected to the power unit and the output end of the second shaft is connected to the driven device, and the gear arrangement being configured to provide a speed reduction when the input end of the second shaft is connected to the power unit and the output end of the first shaft is connected to the driven device.
