Abstract: A mower includes an engine-driven transmission for driving a pair of wheels at rate that varies according to the position of a transmission setting control selected by an operator. The transmission setting control positions a member that has a stop surface proximate to a transmission speed input on the transmission. The transmission speed input is adjusted by one or more levers on the mower. The transmission setting control is adjusted to define a home position of the stop surface relative to the transmission speed input and define a range of travel of the transmission speed input before it contacts the stop surface. The member is spring biased toward the home position but is moveable away from the home position. The position of the transmission speed input when it contacts the stop surface defines a first rate of travel of the transmission. An operator applies a first amount of force to the lever until the transmission speed input contacts the stop surface.

Abstract: A walk behind mower includes an engine-driven transmission for driving a pair of wheels at rate that varies according to the position of a transmission setting control selected by an operator. The transmission setting control positions a member that has a stop surface proximate to a transmission speed input on the transmission. The transmission speed input is adjusted by one or more levers on a handle of the mower. The transmission setting control is adjusted to define a home position of the stop surface relative to the transmission speed input and define a range of travel of the transmission speed input before it contacts the stop surface. The member is spring biased toward the home position but is moveable away from the home position. The position of the transmission speed input when it contacts the stop surface defines a first rate of travel of the transmission. An operator applies a first amount of force to the lever until the transmission speed input contacts the stop surface.

Abstract: A riding lawn mower includes a belt-drive mechanism for transferring power from a drive pulley wheel to a deck pulley wheel to rotate cutting blades of a height-adjustable mowing deck. The drive pulley wheel connects to a drive shaft of a mower engine at a rear portion of the mower and rotatably engages a drive belt. The deck pulley wheel connects to the mowing deck at a location longitudinally spaced from the drive pulley wheel, and rotatably engages the drive belt. A guide pulley wheel, having a circumferential groove for retaining the drive belt, is located between the drive pulley wheel and the deck pulley wheel. An elongated arm pivotally connects at one end to the mower deck near the deck pulley wheel and at an opposite end pivotally engages a mounting bracket connected to the mower frame near the drive pulley wheel. The guide pulley wheel rotatably mounts to the arm near the pivotal connection of the arm to the mower deck.
