A shuttle shifting method for a continuously variable transmission automatically selects a manner of shuttle shifting as a function of certain monitored conditions. As one alternative, the direction of operation of the transmission is changed prior to reducing the vehicle speed to zero, and tilt of a swash plate of the hydrostatic power unit of the transmission is held substantially constant, for achieving fast, smooth shifts at faster starting and ending vehicle speeds, without coming to a complete stop. In another alternative, for slower starting and ending speeds, or other conditions such as a temperature condition is present, the vehicle is stopped by changing swash plate angle before effecting a directional change of the transmission and the swash plate.
A parking brake is controlled in concert with operation of a hydrostatic power unit of a continuously variable transmission, particularly when engaging, disengaging and shuttle shifting the transmission, to provide advantages, particularly when on hills. When particular commands are received, such as shifting to a non-moving position, the parking brake is automatically engaged to hold the vehicle position. A swash plate of the hydrostatic unit can be automatically positioned to anticipate the next command. If that command is received, the brake is automatically gradually or proportionally released and the transmission engaged to effect the commanded movement of the vehicle. If a different command is received, the brake remains engaged as the transmission is configured for the commanded movement, such that no machine movement results. Then the brake is automatically gradually or proportionally released and the transmission engaged to effect that commanded movement.
A method of calibrating a hydraulically operated park brake of a continuously variable transmission of a vehicle. With the vehicle moving at a set, slow speed within a specified range, and the park brake off, a search technique is used, wherein the brake hydraulic pressure is reduced by application of a control signal of a selected test value to apply the brake. When the selected test value is reached, it is held constant, and a condition in a HSU of the transmission is monitored for a change indicative of engagement of the park brake. This will expectedly be in the form of a pressure change and more particularly an increase indicating initial contact between the plates of the brake, and if the HSU change is not detected, the step will time out and another control signal value will be tested.

The feedforward term is based on knowledge of the hydrostatic power unit determined as a function of knowledge of certain parameters, including, but not limited to, hydrostatic power unit pressure, swash plate angle, desired hydrostatic power unit ratio, and pump speed.
A method of calibrating a hydraulically operated clutch in a continuously variable transmission of a vehicle, includes steps of filling the clutch as if for a shift, using a control signal value for achieving a test pressure, and determining a resulting change in a pressure condition in a hydrostatic power unit of the transmission. If the change indicates initial engagement, then a value representative of the signal value used is recorded. If greater than initial engagement is indicated, or the vehicle moved, then the clutch is emptied and tested using a lower test pressure. If initial engagement is not indicated, the clutch is emptied and refilled to a greater test pressure. An exemplary pressure condition is a difference in pressure in lines between a pump and motor of the power unit. During the calibration, the vehicle can be held stationary with a parking brake or the like.
A mechanism for connecting outboard gathering wheels to a moveable crop pick-up assembly on a round baler that incorporates a multi-element linkage to enable the rate of vertical movement of the gathering wheels to be different than the rate of vertical movement of the pick-up assembly. As the pick-up assembly is moved vertically by an actuator, the linkage interconnecting the gathering wheels and the pick-up causes the gathering wheels to also move vertically, but at a rate that is different, usually less, than the rate of vertical movement of the pickup. The linkage enables the pick-up to be raised sufficiently for transport without causing the gathering wheels to impinge upon the baler frame as occurs when both are raised at the same rate. Use of tension members in the linkage allows the gathering wheels to up float during operation without damaging the linkage.

BIOMASS CONVEYING AND DISTRIBUTING SYSTEM FOR A HARVESTER
A biomass conveying and distributing system for separating and distributing lighter biomass residue from heavier or denser biomass, utilizing available air flow from the cleaning system of the harvester. The harvester will discharge a flow of heavier or denser biomass with an airborne flow of lighter biomass residue. The system includes a conveyor for receiving and conveying the heavier or denser biomass, and residue distributing apparatus disposed above the conveyor in a path of at least a portion of the airborne flow of lighter residue, including at least one deflector configured and operable for redirecting the airborne flow sidewardly away from the conveyor, above a passage through which the conveyor passes carrying the heavier biomass away from the harvester.
A cob conveying and cleaning system for use with a corn harvester, incorporating air induction in cooperation with an air flow from the harvester, for cleaning and separating lighter crop residue to be returned to the field from a mixed flow of the residue and cobs, such that the cleaned cobs can be collected, and the lighter residue optionally spread on the field. The air flow and induction are combined to cooperatively lift or draw the lighter residue from the mixed flow, and to optionally spread the removed lighter residue over a field, if desired. The induction apparatus can be located on the harvester, and used as a residue spreader when cobs are not collected.
A biomass feed system includes a device to propel an airborne flow of the biomass along a trajectory within a collection device.
