Abstract: The expansible baling chamber of a large round baler is constructed so as to have chamber-forming elements that act to bias a forming bale away from the chamber inlet so that harvest entering the inlet will be more easily wrapped onto the bale, these chamber-forming elements, in some embodiments, also acting to increase the tension of tensioning means forming part of the baling chamber. Also aiding in the delivery of harvest to the baling chamber is a conveyor having portions located within the chamber inlet.

Abstract: A engine having a timing gear cover with integrally formed coolant inlet and discharge fittings for connection to a radiator. The cover forms a water pump inlet chamber and a water pump outlet chamber defined by the walls of the cover and the front face of the engine block. The lower pressure water pump inlet chamber separates the higher pressure water pump outlet chamber from a timing gear chamber to prevent coolant leakage from the water pump inlet chamber into the timing gear chamber where the lubricating oil will be contaminated. The water pump housing also includes a drain fitting for draining coolant from the engine.

Abstract: The invention is directed to a combine having a chopper arrangement for receiving and chopping harvested crop material that has been threshed and separated. The chopper arrangement comprises a web wheel disk having knives entrained thereon that cooperate with a stationary shear bar to chop the harvested crop material that has been threshed and separated.

Abstract: A baling chamber for a large round baler includes a discharge gate having opposite side walls which meet respective side walls of the main frame along a line of separation that inclines downwardly and to the rear from top to bottom. The bottom of the baling chamber is defined in part by a bottom conveyor which slopes downward to the rear from a front end which delimits a lower side of an inlet through which crop is fed into the baling chamber. The discharge gate carries a lower front roll that supports an endless tension element arrangement and that is itself supported on a tensioning arm arrangement that pivoted to the discharge gate for movement against the resistance of a yieldable spring arrangement so as to permit the lower front roll to move rearwardly from a first position adjacent the inlet, which it occupies at the beginning of bale formation, as the bale grows.

Abstract: A self-propelled forage harvester is equipped with a crop gathering device which transports crop material from the ground to feed rolls that position the crop for being chopped into small pieces by a chopper drum. To prevent pieces of crop material from accumulating on top of the housing structure for the feed rolls and the chopper drum, a flexible shield is mounted between the bottom of the operator's cab and the top of the crop gathering device. Various embodiments are disclosed which feature different access elements of the shield which may be quickly opened to provide access to the feed rolls, chopper drum and other functioning elements provided for processing the crop.

Abstract: A hydrostatic unit is mounted in a transmission housing by a plurality of mounting pins supporting and positioning the hydrostatic unit in the transmission housing. The pins each have a stud portion projecting into a bore in the case of the hydrostatic unit. An externally threaded portion of the pin is threaded into a bore in the transmission housing to mount the pin to the transmission housing. A flange on the pin extends radially outward to overlie and engage the transmission housing surrounding the bore to limit the extent to which the pin is threaded into the transmission housing with the stud projecting into the interior of the transmission housing. Each stud is thus positioned relative to the transmission housing whereby the hydrostatic unit is supported and positioned within the transmission housing. A resilient bushing surrounding the stud serves to isolate the hydrostatic unit from the transmission housing to reduce sound and vibrations transmitted to the transmission housing.

Abstract: A towed, agricultural implement includes an undercarriage supported on ground wheels that are attached to the undercarriage by trailing support arms. An adjusting motor is coupled between the undercarriage and a transverse torsion rod having its opposite ends coupled to the wheel support arms by braces. The adjusting motor is selectively operable for raising and lowering the ground wheels relative to the undercarriage, with the torsion rod acting to absorb shocks between the undercarriage and the wheel support arms.

Abstract: A towed implement is provided with ground support wheels mounted to its chassis by trailing wheel support arms and respective suspensions including lift cylinders with which are associated damping devices that operate in such a way as to prevent damage to a respective cylinder from rebounding forces resulting when the suspension is being returned to its operating position by the release of energy stored in spring arrangements of the suspension after being loaded by an obstacle engaging the associated wheel. In one embodiment, the spring arrangement includes a damping spring located between an end of the associated cylinder and piston, and in another embodiment, the spring arrangement includes a gas pressure reservoir which, by virtue the operation of a reversing link in the suspension, is loaded both when the wheel is caused to move in a first direction by engaging an obstacle, and when the wheel is moved in the opposite direction by the airborne wheel once past the obstacle.

Abstract: A transmission assembly with an infinitely variable transmission component and a constant transmission component wherein the components are designed as modular units. The variable transmission module forms a self-contained functional transmission unit with a variable transmission housing, open on at least one side where it contains a flange. Within the flange area extends at least one infinitely variable output shaft of the variable transmission module. The flange allows the attachment of one constant transmission module of a plurality of modules of different power categories as desired.

Abstract: A system and method for sensing and evaluating the rotation of the auxiliary drive of a utility vehicle is provided. The utility vehicle includes a main drive engine, a gearbox for the propulsion drive and at least one auxiliary drive to which an implement can be selectively connected. The power output of the main drive engine is branched to a first part to a propulsion drive and to a second part to the auxiliary drives. A rotation speed sensor senses rotation speed of the auxiliary drive and provides a speed signal to a control unit. The control unit determines the magnitude or amplitude of the second harmonic of the speed signal and transmits corresponding control signals when a predetermined threshold value is exceeded and/or is not reached. When the control unit determines that the second harmonic of the sensor signals exceeds the threshold value, it permits an increased power output of the main drive engine.

The finger supports are parallel to the eccentric axle and are provided with a plurality of fingers, such that several fingers arranged next to one another in the axial direction are attached to finger supports. The finger supports are distributed around the circumference of the eccentric axle.

Abstract: A cover is provided for a control switch in a vehicle that is movable between open and closed positions. In the cover open position, the switch paddle is freely accessible. In the cover closed position, the switch paddle is partially covered to limit access to the paddle and alert the operator to thereby avoid unintended actuation of the switch. In the closed position, the paddle is still accessible if needed to actuate the switch in an emergency without first opening the cover.
