摘要： A grass conditioning device for a grass mowing machine which receives mown grass through an inlet, discharges the conditioned grass through an outlet, and consists of at least two rows of counter-rotating cylinders. The grass conditioning device is flat, compact and can be economically integrated in mass produced harvesters. For this purpose, several cylinders having substantially the same diameter form a first and at least a second row of cylinders. The cylinder rows are associated with each other, the first cylinder row can be driven separately from the cylinders of the other cylinder rows and the at least two cylinder rows have different peripheral speeds.

摘要： A hydraulically operated variable length top guide coupling member for use in three point linkage couplings for attaching agricultural implements to farm tractors includes a cylinder and a main piston with piston rod carried for longitudinal movement within the cylinder to thereby vary the length of the coupling member. Articulation means are carried at one end of the cylinder and at the other end of the piston rod for connecting the coupling member between a tractor and an agricultural implement. A pair of hydraulic lines provide communication between a source of hydraulic fluid and cylinder spaces on opposite sides of the main piston. A one-way valve is located in the path of communication between each of the hydraulic lines and the respective cylinder spaces. A control piston is carried between the two one-way valves for controlling opening of the valves. Application of hydraulic pressure to one of the hydraulic lines will open its respective one-way valve to permit hydraulic fluid to flow into the cylinder space on one or the other side of the main piston. Hydraulic pressure also acts on the control piston causing it to open the other one-way valve and permit hydraulic fluid to flow out of the other cylinder space into the other hydraulic line. Hydraulic pressure acting on the main piston will thus cause it to move within the cylinder to vary the length of the coupling member. The capability for immobilizing the main piston within the cylinder to fix the length of the coupling member to a desired position is also provided.

摘要： A quick release coupling for connecting a driven shaft having a universal type joint at one end thereof, with a drive shaft, includes a coupling box surrounding the drive shaft and a coupling sleeve carried at the end of the driven shaft for axially receiving an end of the drive shaft. An annular groove is located on the drive shaft and a ball-catch mechanism is carried by the coupling sleeve for snap acting cooperative engagement with the annular groove to produce a positive form fitting engagement between the drive shaft and the coupling sleeve. A locking ring is carried for movement on the coupling sleeve between a release position and a locking position for locking the ball-catch mechanism into engagement with the groove. A spring is used to bias the locking ring into the locking position. Means are provided for engaging the locking ring to hold it in the release position during insertion and removal of the drive shaft into and out of the coupling sleeve. A release lever is pivotally mounted on the coupling box for engaging the locking ring to move it into a release position allowing the ball-catch mechanism to be released from the annular groove so that the shafts may be easily disconnected.

摘要： A coupling device for making a driving connection between a power take-off shaft and a transmission shaft has a coupling hub mounted upon the power take-off shaft and a coupling drum which co-axially surrounds the coupling hub may be journalled upon the hub or attached to the tractor. A coupling sleeve on a power transmission shaft is detachably connected to the coupling hub by a quick release fastener means. The outer surface of the coupling drum has a pivot support upon which an actuating member is pivotally supported. The actuating member has one arm connected to the coupling sleeve and the other arm defines an operating lever such that pivoting of the operating lever will effect a relative axial movement of the coupling sleeve and the coupling hub.

摘要： A coupling device for making a driving connection between a tractor power take-off shaft and a transmission shaft on an implement towed by the tractor has a coupling hub drivingly mounted on the power take-off shaft and a coupling drum coaxially surrounding the coupling hub and substantially fixed with respect to the tractor. A coupling sleeve on a power transmission shaft is detachably connected to the coupling hub by a quick-release fastener means which includes a spring-biased locking ring. A release lever is pivotally mounted on a fixed pivot on the drum and an actuating lever is pivotally connected to the release lever spaced from the fixed pivot. Pivotal movement of the actuating lever will pivot the release lever about its fixed pivot so that the release lever engages the locking ring to release the fastener means and thereby disengaging the sleeve from the hub. Further pivotal movement of the actuating lever causes the actuating lever to pivot about a stop on the drum such that the actuating lever engages a stop on the sleeve to push the disengaged sleeve from the hub.

摘要： An adjustable length upper guide member for the hitch attachment of a tractor has an outer tubular guide element within which is telescopingly positioned an inner guide element so as to be relatively displaceable thereto. A housing on the outer guide element has a pair of jaws pivotally mounted therein and the jaws each have first arms which are engageable with annular grooves on the inner guide element and second arms which form actuating cams facing each other. A lever has an eccentric portion within the housing and one side of the eccentric portion is engageable against the housing and the other side of the eccentric portion engageable with the actuating cams so that pivoting of the lever causes the eccentric portion to act upon the cams and pivot the jaws to a disengaged position.
