Height of cut and rake adjustment system
A height of cut and rake adjustment system for a rough, trim and surround mower deck with a pair of front height of cut arms and a pair of rear height of cut arms. Each height of cut arm is pivotably mounted to the mower deck on a pivot axis below an upper end of each height of cut arm. An adjustable height of cut linkage extends between the upper end of each front height of cut arm and the upper end of each rear height of cut arm. An adjustable rake linkage extends between the upper end of each front height of cut arm and an intermediate portion of each rear height of cut arm below the pivot axis.
Mower deck insert
A mower deck insert includes a first cutting chamber, a second cutting chamber, and a discharge passage extending adjacent to the first cutting chamber and the second cutting chamber. The first cutting chamber includes a first axial scroll extending about a first vertical axis. The first axial scroll includes a first upper surface having a first start region and a first end region. The second cutting chamber includes a second axial scroll extending about a second vertical axis. The second axial scroll includes a second upper surface having a second start region and a second end region. The first start region is vertically lower than the first end region, and the second start region is vertically lower than the second end region.
Flex wing mower
A mowing machine may include a central cutting deck generally disposed in a neutral mowing plane and a wing cutting deck pivotable with respect to the central cutting deck. A main gearbox may be connected to a wing gearbox by a wing driveline. The main gearbox may be disposed a sufficient distance forward of the central cutting deck and the wing cutting deck to permit the wing cutting deck to pivot about a hinge in a range of motion without disconnecting the wing driveline from either the main gearbox or the wing gearbox.

Three-point hitch mount systems
Three-point hitch mount systems for connecting an implement to a tow vehicle having two lower hitch arms and an upper link arm are disclosed. The hitch mount systems may include a lift bar configured to be attached to the two hitch arms of the tow vehicle. The hitch mount systems may include a yoke assembly. The yoke assembly includes a forward-facing slot and a downward-facing slot for removably receiving the lift bar.
AGRICULTURAL DEVICE WITH TWO WORK UNITS
An agricultural device with two work units, the device being able to occupy a work configuration and a transport configuration and comprising a support arm pivotally mounted on a chassis around a lift axis substantially parallel to the direction of advance and around which the device is pivoted to reach the various configurations mentioned above, each unit being pivotally mounted relative to the support arm around a connecting axis, each unit comprising a respective guided end and a respective free end further away from the corresponding connecting axis than its guided end. The agricultural device includes a central actuator configured to apply on each of the units a biasing force opposed to a downward pivoting movement by its free end around the corresponding connecting axis, at least in the work configuration.
MULCH GATE CONTROL LEVER
A mulch gate control lever includes a handle that moves a mulch gate on a vertical pivot axis between a first mulching position and a second side discharge position. A torsion spring biases the handle to move into a first position slot at a first end of a slotted bracket to retain the mulch gate at the first mulching position, and into a second position slot at a second end of the slotted bracket to retain the mulch gate at the second side discharge position.
Stand-on mower with an oscillating front axle
A zero turn radius lawnmower, such as a stand-on lawnmower, including a main frame having a first end portion and a second end portion, a pair of drive wheels operably coupled to the second end portion of the main frame and configured to be driven independently in both forward and reverse directions, and a front axle assembly pivotally coupled to the first end portion of the main frame about a single axis. The zero turn radius lawnmower also includes a pair of caster wheels coupled to respective ends of the front axle assembly such that the pair of caster wheels are able to move relative to the main frame, as well as a mower deck coupled to the main frame by at least one first linkage and coupled to the front axle assembly by at least one second linkage.

ELECTRIC WORK VEHICLE
An electric work vehicle includes a traveling motor to drive wheels, a working motor to drive a work machine, a manipulator to direct a target rotation speed of the traveling motor and operation of the work machine, a controller to control the traveling motor and the working motor according to operation of the manipulator, and a temperature sensor to detect temperature of the working motor. The controller maintains or changes a target torque range of the working motor according to a detected temperature of the working motor, and the controller maintains or changes a target rotation speed of the traveling motor so that a calculated output torque value of the working motor falls within the target torque range.
