The technology disclosed herein relates to a grounds maintenance vehicle. The grounds maintenance vehicle has an engine and an engine shroud defining a cooling volume around the engine. The shroud defines a shroud intake. An engine oil conduit extends from the engine and a heat exchanger is coupled to the engine oil conduit.

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.

A work evaluation system configured to effect evaluation of a grass mowing work performed by a work vehicle includes a state information acquisition section for acquiring vehicle state information indicative of a state of the work vehicle when performing the grass mowing work, a sound data acquisition section for acquiring sound data comprised of collection of sounds around the work vehicle, a foreign object amount calculation section for calculating an amount of foreign objects present in the work land which come into contact with a mowing blade in the course of the grass mowing work and an evaluation section for evaluating the grass mowing work performed in the work land, based on the vehicle state information and the foreign object amount.

A head 1 for brush cutter suitable for cutting grass and herbaceous plants having a support element 2, rotatable about a vertical axis Y-Y thereof, connected to a series of first pins 3 and a series of second pins 4. The series of first pins 3 is coupled to a first plurality of cutting elements 5 and the series of second pins 4 is coupled to a second plurality of cutting elements 6.

Said first plurality of cutting elements 5 defines a cutting plane P1 and said second plurality of cutting elements defines a second cutting plane P2, spaced apart from the previous one. The first and second plurality of cutting elements 5, 6 having, over an angular sector of 360° , an alternating arrangement.

In some embodiments, apparatuses, systems, and methods are provided herein useful to mowers. In some embodiments, a mower comprises a frame, a plurality of wheels connected to the frame, a mower deck located within the frame defining a cutting chamber, a first blade that is elongated and rotates about a generally vertical axis and has a fin extending from at least one of the ends with a concave surface that faces generally away from the ground surface, a second blade that is circular and rotates about a generally vertical axis, a propulsion unit that is supported by the frame and rotates the blades, a discharge opening allowing discharge to exit the cutting chamber, and a container pivotally coupled to the mower pivotable between a first position and a second position, with the first position of the container configured to collect the discharge from the cutting chamber through the discharge opening.

Provided is an electric work vehicle having a simple configuration, yet allowing a hydraulic cylinder to function appropriately even in a low-temperature environment. An electric work vehicle includes a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder and includes also a hydraulic system for feeding work oil to these hydraulic cylinders and a traveling motor. The hydraulic system includes an oil heating circuit for heating the work oil using heat generated from the traveling motor.

A method of autonomously controlling the ground speed of a harvester, such as a self-propelled or towed wind rower, uses both the engine speed and the header speed as control parameters to increase or decrease the ground speed as necessary to maintain efficient harvester operation over varying terrain and crop conditions. A control system includes a controller which receives signals from sensors indicative of engine speed, header speed and harvester ground speed and uses actuators to control the header speed, engine speed and harvester ground speed. An operator interface permits an operator to engage or disengage the autonomous mode of control system operation, as well as to directly control the harvester.

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.
