  • Publication number: 20250127082
    Abstract: A compact stand on mower deck belt system includes a first blade spindle and a second blade spindle rotatably mounted to a height adjustable mower deck under a stand on mower frame. An engine rigidly mounted to the stand on mower frame has a driveshaft over the mower deck. A first deck belt transmits rotational power from a driveshaft pulley to a pulley on one of the blade spindles on the mower deck. A second deck belt transmits rotational power between the pulleys on the blade spindles. At least one of an idler pulley and a tensioner pulley is rotatably mounted on the mower deck forwardly of the blade spindles and is engaged by the first deck belt. A maximum fleet angle of the first deck belt is between the driveshaft pulley and one of the idler pulley and the tensioner pulley.
