Abstract
Provided is a mower system that includes an idler pulley, a deck drive pulley coupled to a drive shaft of a mower motor and an intermediate pulley coupled to the mower and positioned to be engaged by a portion of the deck drive belt spanning between the deck drive pulley and the idler pulley. The deck drive pulley located a first distance from the idler pulley and the intermediate pulley located a second distance from the idler pulley, with the second distance being greater than the first distance.
Claims23
A stand-on riding mower system, comprising:
- a mower frame;
- a mower motor coupled to the mower frame, the mower motor comprising a drive shaft configured to rotate;
- a mowing deck system coupled to the mower frame and configured to be raised or lowered relative to the mower frame and the mower motor, the mowing deck system comprising an idler pulley and a spindle pulley, wherein the spindle pulley is coupled to a mowing blade and engaged by a deck drive belt, wherein circulation of the deck drive belt is configured to rotate the spindle pulley and the mowing blade coupled to the spindle pulley, and wherein the idler pulley is biased to push against the deck drive belt to maintain a tension of the deck drive belt;
- and
- a deck drive belt system comprising:
- the deck drive belt;
- a deck drive pulley coupled to the drive shaft of the mower motor and engaged by the deck drive belt, wherein the deck drive pulley is configured to rotate with the drive shaft, and wherein rotation of the deck drive pulley is configured to cause the circulation of the deck drive belt;
- and
- an intermediate pulley coupled to the mower frame, wherein the intermediate pulley is engaged by a portion of the deck drive belt spanning between the deck drive pulley and the idler pulley,
- wherein the deck drive pulley is located a first distance from the idler pulley, the intermediate pulley is located a second distance from the idler pulley, and the second distance is greater than the first distance, and
- wherein the mower motor and the intermediate pulley are rigidly coupled to the mower frame such that a position of the intermediate pulley is fixed relative to a position of the deck drive pulley during operation of the mower.
