摘要： A belt clutch control apparatus is disclosed having a control handle and linkage means for selectively controlling the transmission and power from a driving pulley to a driven pulley through a driving belt. In a preferred embodiment, the apparatus is specially adapted to control the operation of the cutting blades on a riding mower. The linkage includes an undercenter connecting link for transmitting rotational movement of the control shaft to a bellcrank, which engages a tension spring to operatively move an idler pulley between engaged and disengaged positions relative to the driving belt. The undercenter link moves exclusively between first and second undercenter positions, and is never forced into an overcenter position. An assist spring is provided for securing the undercenter link in both its on and off undercenter positions, thereby relieving the idler pulley spring for this purpose. The linkage significantly reduces both the travel and effort required to move the control handle between its on and off positions.

摘要： Dual lever steering controls with control stops are provided for a zero turning radius mower. Each control arm is mounted to a neutral position lever that is pivotable between a full forward drive position and a full reverse drive position. Each control stop is mounted to block the control arm and neutral position lever from pivoting to a position under a minimum forward speed. Each control stop may be biased to the minimum forward speed position, and also may be pivotable between an operating position and a non-operating position.

摘要： Apparatus for suspending, raising and lowering the cutting deck beneath the frame of a riding lawn mower, comprising a pair of lifting arms having first ends rotatably secured to the frame and second ends secured to the cutting deck, rotation of the lifting arms effecting vertical movement of said cutting deck. A pedal operated lifting mechanism is provided, selectively operable by the user of the mower to rotate the lifting arms, thereby raising and/or lower the cutting deck. A suspending member is disposed through an opening in the frame above a portion of one lifting arm, said suspending member having a lower end secured to the lifting arm and an upper end disposed above the opening in the frame. A support member secured to the upper end of the suspending member engages the frame to limit downward movement of the suspending member and lifting arm, and is selectively adjustable by the user to adjust the cutting height of the deck. Upon moving the cutting deck to its upper-most raised position, the suspending member engages the frame adjacent the opening and automatically locks the cutting deck in its raised position. A handle on the suspending member allows the driver to adjust the cutting height with the cutting deck in either its cutting or raised position.

摘要： An aerator having a flexible frame for use on sloped or undulating ground surfaces of golf courses and other turf. The aerator includes a pair of frame sections linked together at a horizontal pivot axis, one of the frame section supporting a coring head. A ground sensor is pivotably attached to one of the frame sections so that the ground sensor may pivot in response to changes in ground slope and provide output relating to the magnitude of the change. Based on the output, a flex frame actuator pivots the pair of frame sections with respect to each other.
