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 crop harvester is provided with a rotary type cutter bed in which a series of rotary cutters extend across the path of travel of the machine for rotation about individual upright axes. A hydraulic drive for the cutter bed includes a variable volume pump driven by the output shaft of an engine associated with the harvester. The operating circuit of the hydraulic drive pumps oil through the circuit at a certain rate of flow, depending upon the engine speed and the position of a swash plate within the pump. A control circuit communicating with the operating circuit is capable of sensing load in the operating circuit tending to lug down and reduce the speed of the engine, which would normally reduce the flow rate and hence the cutter speed. However, in response to detecting such increased load, the control circuit compensates by adjusting the position of the swash plate so as to correspondingly pump more oil at the lower engine speed, thus maintaining the cutter speed essentially constant.

摘要： A work vehicle for cutting crops includes a header a supported by a chassis of the work vehicle. The header includes a cutter assembly having a cutter bar frame supporting a series of rotary cutters arranged in a lengthwise direction. A gear train, having a first gear and a second gear, is coupled to the series of rotary cutters to transfer power thereto. A cutter control system includes a first motor coupled to the first gear of the gear train and a second motor coupled to the second gear of the gear train. A controller, including a processor and memory architecture, is operably connected to the first motor and the second motor to control operation thereof. The cutter control system drives the first gear at a first speed via the first motor and drives the second gear at a second speed via the second motor. The second speed is different than the first speed to pre-load the gear train into enmeshing engagement with each other in one rotational direction.

摘要： The present walk-behind, self-propelled motor has two hydraulic motors whose rotors are directly connected to the hubs of respective drive wheels on opposite sides of the mower deck toward the rear. These motors are driven by respective pumps, each of which has its direction and rate of fluid displacement controlled by a handle mechanism on the upper end of a corresponding fixed handle extending up from the deck at the rear. Each handle mechanism has a pivoted handle coating with a locking lever to set the corresponding pump in neutral, forward or reverse. An internal combustion engine drives both pumps as well as cutting blades located below the mower deck toward the front. Vertically pivoted wheels are located in front of the mower deck.
