Vehicle drive and control system
A drive and control system for a lawn tractor includes a CAN-Bus network, a vehicle controller, a pair of hydrostatic or electric transaxles controlled by respective electronic drive controllers, and one or more steering and drive input devices coupled to respective sensor(s) for sensing user steering and drive inputs. The vehicle controller communicates with one or more vehicle sensors and one or more vehicle controllers that control one or more vehicle components via the CAN-Bus network. The vehicle controller processes the user's steering and drive inputs and posts on the CAN-Bus network digital drive signals configured to obtain the desired speed and direction of motion of the lawn tractor. The electronic drive controllers convert the digital drive signals to appropriate signals for driving the hydrostatic transaxles or the electric transaxles, as equipped, based on tunable motion parameters to obtain the desired speed and direction of motion of the lawn tractor.

Self-adjustable feeder for sugar cane harvesting device
A self-adjustable feeder for a sugarcane harvesting device having two vertical feeding rollers rotating in opposite directions, aligned side by side and horizontally moving, kept under traction one against the other by at least one actuator. The upper edges of both feeding rollers, besides being coupled to hydraulic engines rotating in opposite directions, are also hinged to a rear opening and closing structure, with a guiding system to change the distance between the vertical centers of the feeding rollers.
Drive transfer member for operably coupling a draper header to a harvesting machine
A draper header is attached to a harvesting machine by an adapter including a bottom feed draper and an upper feed roller driven by a coupling from an output of the machine rotatable about an axis parallel to the forward direction and a right angle gearbox. The feed roller is mounted at each end allowing independent up and down floating movement of the ends and there is provided a mechanical linkage using two chains and an idler shaft between the output shaft of the gear box an input shaft of the roller with a universal coupling therebetween. The gear box is located at least partly underneath the discharge opening and underneath the feed roller, rearwardly of the rear guide roller of the feed draper, rearwardly of the axis of rotation of the feed roller and underneath a feed pan which is inclined upwardly and rearwardly over the gear box.

Work Vehicle
Provided is a work vehicle capable of efficiently performing grass collecting work by decelerating a traveling machine body in a case where the size of a bale is large and a case where the pickup load of straw grass is large. The work vehicle includes a traveling machine body 1, a roll baler unit 2, a bale detection unit 31 configured to detect a size of the bale formed by the roll baler unit 2, a load detection unit 32 configured to detect a pickup load of straw grass in the roll baler unit 2, and a traveling control unit 17A capable of decelerating the traveling machine body 1 when a size of the bale is equal to or larger than a setting value B1 and when a pickup load is equal to or larger than a setting value L. A deceleration D2 is larger than a deceleration D1.

Park brake and traction drive bypass interlock
Methods and apparatus for a lawn maintenance vehicle park brake and traction drive interlock are provided. A park brake mechanism is selectively operable between an engaged position and a disengaged position. A traction drive is also mounted to the lawn maintenance vehicle, the traction drive having a disable mode which prohibits transmission of a driving force from the traction drive to a drive wheel. A first operable connection between the park brake mechanism and a wheel brake activates the wheel brake. A second operable connection between the park brake mechanism and the traction drive activates the disable mode of the traction drive. A method of controlling a lawn maintenance vehicle with a park brake and traction drive interlock include the steps of providing a lawn maintenance vehicle, providing an operable park brake mechanism, providing a first operable connection, and providing a second operable connection.
