摘要： A lawn-mowing vehicle is provided in which a facing-the-ground surface of a lawn-mowing unit can manually be shifted. The lawn-mowing units of the lawn-mowing vehicle can be rotated. There is provided a first connection mechanism that connects each of the lawn-mowing units to the arm, in such a way that the lawn-mowing units can be shifted by rotation between their work positions and the biased side positions that are biased toward the sides of the carriage. There is provided a second connection mechanism that connects each of the lawn-mowing units to the first connection mechanism so as to be rotatable, in such a way that the lawn-mowing units placed at the biased side positions can be shifted from a facing-the-ground posture to an outward posture.

摘要： A height of cut control system on a mower deck includes a linear actuator connected to the lift linkage. A height of cut dial has a plurality of operator-selected desired cutting heights, and a deck height control is connected to the electronic controller that commands the linear actuator to lower or raise the mower deck to the desired cutting height when the deck height control is in a down position or an up position. A deck height display provides visual feedback of operator selected cutting height and actual cutting height. If the actual height is at least a specified amount off the operator selected cutting height, the electronic controller may automatically adjust the mower deck by commanding the linear actuator to move the mower deck to the desired cutting height.

摘要： A rotary mower has a center mower deck and a hitch arm assembly adapted at a front end for connection to a tractor drawbar. A hydraulic pump is mounted on the hitch arm assembly and connected to a hydraulic motor mounted on the center mower. An upward arm section of the hitch arm assembly extends upward from a front portion of the hitch arm assembly to provide a desired clearance distance between a middle arm section of the hitch arm assembly and the ground, and a downward arm section of the hitch arm assembly extends downward from the middle arm section to a rear end of the hitch arm assembly which is pivotally connected to the mower deck about a hitch pivot axis oriented horizontally and perpendicular to the operating travel direction. The hitch pivot axis is located at a vertical position below top edges of the front wheels.

摘要： A contour following mowing apparatus and associated methods are described that include a mower platform. A rotational coupling can be configured to couple to a motor, wherein the rotational coupling includes a fixed portion and a rotatable portion, and the fixed portion of the rotational coupling is attached to the mower platform. A shaft can be operably coupled to the rotatable portion of the rotational coupling, wherein the rotational coupling is configured to rotate the shaft, and the shaft is configured to translate axially from a first location to a second location with respect to the rotational coupling. A blade can be coupled to the shaft and positioned outwardly from the shaft, wherein the blade includes a cutting edge. In one example, the elements above can be included in a mowing module that is coupled to the mower platform with at least one fastener.

摘要： In a work vehicle, because of growing need to equip a DPF for exhaust gas countermeasures near an engine and a request of increasing the size of a fuel tank, a system including the fuel tanks provided below a floor step and on left and right sides of a transmission case has been employed. However, when a lawn mower is installed between front wheels and rear wheels, an increasing width of a vehicle body becomes a problem.To solve the problem, a locus of the raising and lowering operation of a lawn mower 5 is specified by a parallel link formed of left and right front links 43, 43 and left and right mid links 45, 45, and in a work vehicle where the lawn mower 5 is freely raised and lowered, the left and right mid links 45, 45 are respectively disposed between a transmission case 3 and fuel tanks 16L, 16L.
