A two-speed transmission for towed agricultural equipment activated through power take-off of a towing machine comprising an input shaft. A pinion arranged on the input shaft entering into a transmission box activated by the input shaft through a hypoid tooth and/or conical coupling; a crown gear fixed onto an intermediate shaft arranged orthogonal to the input shaft having two different dimension gears. One of the two gears with a clutch is connected to the intermediate shaft, the gears of which being coupled with a gear on an output shaft. The connection of the intermediate shaft/gear of the output shaft without clutch one of the gears has a free wheel connection with the respective shaft. The output shaft is arranged in the same plane as the input shaft and the output shaft is connected at its two ends outside the transmission box with a shredding head.

A system for monitoring the operational status of ground-engaging tools of an agricultural implement. The system includes a frame and an assembly including an attachment structure configured to be coupled to the frame and a ground-engaging tool pivotably coupled to the attachment structure at a pivot point. The system further includes a shear pin at least partially extending through both the attachment structure and ground-engaging tool to prevent pivoting of the ground-engaging tool about the pivot point. Additionally, the system includes a sensor configured to detect a load applied through a pivot member extending through at least one of the frame or assembly at any pivot point between the frame and the ground engaging tool. The system further includes a controller, communicatively coupled to the sensor, configured to determine a change in the working condition of the shear pin based on the detected load applied through the pivot member.

A utility vehicle is disclosed. The utility vehicle is configured to support a removable implement. The removable implement may include one or more components configured to be powered by a power take off system of the utility vehicle. The removable implement may also include one or more components configured to be powered by a hydraulic system of the utility vehicle. An operator of the utility vehicle, without exiting a cab of the utility vehicle, can couple the implement to the utility vehicle such that the hydraulic components are hydraulically coupled to the vehicle's hydraulic system and such that the components of the implement configured to be powered by a power take off system of the utility vehicle are operably coupled to the power take off system of the utility vehicle.

The disclosure relates to a quick-release device for a tractor PTO shaft, including a first body having a first outer surface and a second outer surface and a first thickness disposed therebetween; a plurality of slots defined on the first body; a second body having a third outer surface and a fourth outer surface and a second thickness disposed therebetween; and a plurality of extensions extending from the second body, wherein the plurality of extensions are configured to removably engage with the plurality of slots.

A protector for a coupler for connecting a drive shaft of an implement to a tractor power take-off (PTO) comprises an elongated shaft having a proximal end and a distal end. The shaft may include a plurality of splines formed around a circumference of the shaft which extend longitudinally along the shaft from the distal end toward the proximal end. The splines may be arranged for meshing engagement with internal splines within a bore of the coupler. A grease zerk fitting may be disposed at the proximal end of the shaft through which grease can be extruded. A channel may extend through the shaft from the proximal end toward the distal end that is in fluid communication with the grease zerk fitting. A plurality of exit ports may be disposed around the circumference of the shaft at one or more positions along the length of the shaft, which are in fluid communication with the channel. Grease may be extruded into the protector through the grease zerk fitting, through the channel, and out through the exit ports to the exterior of the device.
