Abstract
The mower attachment includes a drive subassembly which is adapted to be detachably connected to the front axle of the tractor. Specifically, the drive subassembly is adapted to be connected to downwardly opening channel members rigidly secured to transverse, oscillating front axle member. The mower attachment also includes a mower subassembly which is connected to the drive subassembly by a draft link structure. The drive subassembly includes a clutch pulley rotatably mounted on a clutch pulley support bracket which is in turn pivotally connected to a frame part of the drive subassembly so that it may swing between clutching and declutching positions. The clutch pulley support bracket is connected to a clutch control lever on the tractor by a disconnectable clutch control linkage. The drive subassembly also includes an idler pulley disposed on an oblique axis forwardly of the clutch pulley. The clutch and idler pulleys lie in planes which are transverse to one another intersecting on a longitudinally extending line which passes through both pulleys (in at least one adjusted position of the clutch pulley support bracket). A drive belt cooperatively engages the idler and clutch pulleys as well as a drive pulley on a power take-off shaft from the tractor engine and a pulley on the mower subassembly. The clutch pulley is disposed between portions of the drive belt which extend rearwardly from the idler pulley thus permitting a compact arrangement of components in the drive assembly. The mower subassembly includes blades mounted on driven spindles which include pulleys at their upper ends. A second belt is disposed in driving relation to pulleys connected to the spindles. A braking mechanism is included in the mower subassembly and is connected to the clutch operating linkage at the drive subassembly by a flexible cable.
