A control arrangement is disclosed which is particularly suited for selective operation of a reciprocable member, such as the valve spool of a hydraulic power takeoff valve on a material handling implement. The arrangement includes a handle bracket which is adapted to be mounted in association with the hydraulic valve, and further includes a control handle adapted for releasable connection with the spool of the valve. The movement of the handle is guided by the handle bracket such that in a first position of the handle with respect to the valve spool, the handle can be positioned within a detent notch in the bracket for maintaining the valve spool out of its neutral position in opposition to its associated centering springs. The control handle can further be connected to the control member in a second position. In this second position, the handle is no longer receivable within the detent notch, thus requiring continued manipulation of the handle to maintain the valve spool out of its center, neutral position.

A drive control assembly including a rocking foot pedal and a rotatable control lever for effecting forward and reverse motion of a machine. The control lever is operably connected to a rotatable selector plate for setting the direction of machine movement. The foot pedal is operably connected to the rotatable selector plate for controlling the speed of machine movement in either the forward or reverse direction. The rotatable selecor plate includes a slot having directional positions for forward, neutral, and reverse directional control, respectively. The foot pedal is connected to a pin in the selector plate slot by an actuating linkage and the control lever is connected to the same pin by a coupling element. The selector plate pin is movable in the slot from a neutral position to either a reverse or forward directional position in response to the shifting of the control lever. After the control lever is shifted to a directional position, it remains stationary while the joint formed between the selector plate pin and the ends of the coupling element and actuating linkage moves along the selector plate slot in response to downward depression of the foot pedal. The movement of the joint between the selector plate pin, coupling element and actuating linkage along the selector plate slot does not affect the position of the control lever.

Ground drive control

A rotary cultivator is disclosed which is adapted to be supported upon a rear-mounted tractor hitch. The cultivator includes a tined cultivation shaft and a hydraulic motor and drive mechanism for driving one end of the shaft. The cultivator includes an arrangement for selectively varying the speed ratio of the hydraulic motor and cultivation shaft, as well as for selectively changing the length of the cultivation shaft so that the width of the path of soil cultivation may be changed as desired. A pair of spaced, negatively angled ground-engaging surfaces are provided on the cultivator housing for urging the cultivator downwardly during forward movement thus providing a more uniform depth of penetration during soil cultivation.

A starting mixture control for a carburetor that controls the richness of the fuel mixture being fed to an associated engine after initial starting, the carburetor having a throat for supplying air to the engine that is equipped with a choke valve upstream from a venturi constriction, a throttle valve downstream from the venturi constriction, a fuel bowl with a fuel nozzle opening into the throat at the venturi constriction, a bowl vent passage for providing atmospheric pressure to the fuel bowl during normal engine operation, and a pressure transmitting by-pass duct communicating between the bowl vent passage and the carburetor throat. When the engine is cranked with the choke closed a rich fuel mixture is delivered to the engine, and when the engine starts the duct transmits the low pressure on the downstream side of the choke valve to the fuel bowl to reduce the flow of fuel from the fuel nozzle to lean out the fuel mixture delivered to the engine to prevent stalling until the choke valve is adjusted to an open position.

Carburetor starting mixture control

A carburetor having a venturi constriction within an air passage leading to the engine intake manifold, a fuel bowl with a discharge nozzle for delivering fuel to the venturi constriction, and a bowl vent passage between the fuel bowl and a position at atmospheric pressure, includes a duct communicating between the venturi constriction and the fuel bowl. A solenoid valve is disposed in the bowl vent passage and is operatively connected to the ignition; the valve is open when the ignition is turned on so that the fuel bowl is exposed to atmospheric pressure allowing the nozzle to discharge fuel into the venturi constriction, and it is closed when the ignition is turned off. With the valve closed, the pressures in the venturi constriction and the fuel bowl are equalized preventing the flow of fuel through the nozzle to the venturi constriction and inhibiting 'dieseling' after ignition shut-off.
