A friction disc transmission including a conventional drive disc rotatable about a vertical axis and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis. The driven friction disc is rotatably supported between a fixed frame member and a floating plate member. The floating plate member is lifted or lowered by a bellcrank having a pin that is movable within a slot in the floating plate member. A clutch pedal is connected to the bellcrank for pivoting the bellcrank thereby raising and lowering the floating plate member and driven disc. The bellcrank pin is biased by a spring which is connected to the bellcrank to apply a downward normal force on the floating plate member and driven disc. Guide pins are provided on the floating plate member which are engageable with guide brackets to limit the vertical movement of the floating plate member. The friction disc transmission is placed into a forward or reverse drive condition by partially releasing the clutch pedal to permit initial engagement and slippage between the discs. When the clutch pedal is completely released, the bellcrank spring rotates the bellcrank for biasing the bellcrank pin against the lower edge of the floating plate slot thereby providing an additional normal force between the driven and drive discs.

A self-elevating wood splitter is disclosed which includes an arrangement for selectively adjusting the vertical position of the wood-supporting frame of the splitter. The splitter includes a height adjusting arrangement which generally comprises a pair of four-bar linkages, and further includes an elevating mechanism which permits the hydraulic actuator of the splitter to be employed for operating the height adjusting arrangement to effect raising and lowering of the splitter's frame. A locking mechanism is provided which includes a pair of adjustment members operatively associated with the height adjusting mechanism of the splitter. Notably, the arrangement operates such that the wood-supporting frame can be raised by operation of the elevating mechanism before selective adjustment of the locking mechanism is effected. By this construction, the load on the locking mechanism can be relieved before adjustment, thus greatly facilitating convenient repositioning of the adjustment members to permit selective adjustment of the height of the splitter's wood-supporting frame.

The disclosed friction disc transmission includes a conventional drive disc rotatable about a vertical shaft and a vertical friction disc engaging the top horizontal face of the drive disc to be driven about a horizontal axis. The friction disc is rotatably supported on a pivot frame having a sprocket drive connected to a sprocket on the wheel axle. The vertical drive disc shaft is mounted on a transversely swingable support for movement of the drive disc relative to the driven friction disc and control of the rotational speed and direction of the driven disc. The support includes a control plate having camming surfaces which lift the driven disc over the center neutral axis of the drive disc, reducing wear of the driven disc when the transmission is in neutral. The control also includes a clutch-brake mechanism independent of the control plate including a lever connected to a rotatable link means. The link means is operably connected to the pivot frame and a brake shoe and is operable upon actuation of the lever to sequentially vertically lift the frame means and the friction disc out of engagement with the drive disc and engage the brake shoe against the friction disc to stop rotational movement of the friction disc.

The disclosed chute assembly is particularly adapted to collect the discharge from a rotary lawn or garden tractor, particularly a mower having a vertically adjustable rotary blade housing. In the disclosed embodiment, the chute between the blade housing and the hopper has two telescopically adjustable sections, including a discharge chute which is pivotally supported on the hopper opening lip and a spiral receiving chute which is fixed to and communicates with the blade housing. The mower blade may thus be adjusted vertically without affecting the chute assembly and the chute sections may be easily removed for cleaning, storage or repair.

An oscillating gear ratchet drive unit transmits rotating motion and torque from a drive gear to a driven shaft in a preselected direction of rotation and includes a shaft and a gear operably connected to a drive gear and positioned transversely with respect to the shaft and supported by the shaft. Ratchet crown wheels are provided on the opposing major faces of the gear and have camming surfaces for producing axial movement of the gear on the shaft, with each camming surface terminating in an axial surface. Pins project radially outwardly from the shaft adjacent to each ratchet crown wheel and engage an axial surface to the drive shaft, and are adapted to engage the camming surfaces to move the gear axially whenever the shaft rotates faster than the gear, while also accommodating and limiting axial movement of the gear on the shaft.
