A crop guide comprising one or more generally wedge-shaped guides configured to interact with a crop discharge stream as it is discharged from an agricultural mower having a counter-rotating disc cutterbar. The guides are positioned rearward from the cutterbar, with one guide being generally positioned on an axis centered between each pair of converging-rotation disc cutterheads where crop material flow is concentrated. Each guide is generally pyramidal in shape, having a pair of surfaces angled with respect to one another and forming a triangular pyramid form with respect to a third generally planar surface, typically the mower swathboard. The vertex of the pyramid is oriented upstream in the crop flow so that a portion of the crop flow is split by the angled surfaces and laterally dispersed. This dispersion of crop material produces a crop mat on the ground behind the mower having a more uniform thickness compared to that produced by a traditional mower using a counter-rotating rotary cutterbar.

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.

The orientation of the vehicle relative to the direction of travel of the vehicle can be used to correct the error in the location of an implement mounted on the vehicle determined by a GPS system mounted on the vehicle or the vehicle towing the implement due to crabbing of the vehicle as the vehicle travels substantially perpendicular to a significant slope.
The cooling system of a skid-steer loader provides for heat exchangers, e.g. liquid, oil coolers, mounted in the upper portion of an engine compartment and in direct communication with a forced air flow.
