Abstract: This specification describes a mechanism for clamping an air filter in a vehicle by a floating lever which is actuated by a cranked rod, spring mounted on the vehicle. The spring exerts a clamping force against filter and floating lever ensures force is evenly applied.

Abstract: A crop-gathering table for a combine harvester has a tubular main cross beam on which are supported at spaced intervals a plurality of angle iron ribs extending downwardly and then forwardly to support the back wall and then the bottom wall of the table and to support the cutter bar at the front end of the ribs. A stiffener plate is secured to the bottom of the ribs so that with the bottom wall of the table a plurality of hollow cells are formed to provide a rigid but lightweight table structure.

Abstract: A peanut picking machine has a side mounted fork to lift dried peanut heaps and dump them into a hopper. A conveyor feeds crop from the hopper to peanut picking apparatus through a feed opening. An adjustable shutter controls the rate of feed through the opening both by virtue of its position and its attitude with respect to the conveyor.

Abstract: Cane chopping apparatus for use in a sugar cane harvester comprises contra-rotating cane chopping elements at least one of which carries a cane feed member to assist the passage of cane in the desired manner. The cane feed member is formed of resilient material for example textile-reinforced rubber sheeting. This material improves the feeding action of the feed member and renders it less susceptible to damage.

Abstract: A grain saving apparatus for a combine disposed at the discharge end of the combine includes a vaned member rotated relative to a straw support in the form of an open grate concave to receive a mixture of straw and grain from straw walkers in the separating sections of the combine and to change direction and velocity of movement of the material and direct it between the vaned member and straw support to separate grain and straw so that the heavier grain is collected for processing in the combine and the lighter straw is discharged by the vaned member to the rear of the combine.

Abstract: A crop gathering table for combine harvesters has a pair of auger tubes each supported on bearings at one end of the table and bolted together at the center. Supported on the fastening bolts are a plurality of anti-friction rollers lying between the adjacent ends of the augers. A circular track forms a support for the rollers and is self-supported from the main frame of the table.

Abstract: Automatic height control system for crop pick up reel of peanut combine. The implement is supported at the front on the draught links of a tractor and at the rear on its own ground wheels. A height sensing wheel adjacent the pick-up reel senses ground contours. A linkage of pivotally interconnected links transmits height control signals from the height sensing wheel to the top control link of the tractor's hitch whereby the tractor's draught control system maintains the reel at constant height.

Abstract: Peanut digging apparatus having a quick-attach side delivery conveyor for the peanut crop. With said conveyor detached, crop can be deposited directly behind the apparatus. With said conveyor attached crop can be deposited at a laterally offset position. Using these two modes of operation successively, large windrows of crop can be built up in stages while allowing time between said stages for natural drying of the crop.

Abstract: A rethresher and conveyor for combines in which a rotary blower is positioned to receive tailings from a combine and in which a blower is provided with threshing elements coacting with stationary elements to rethresh the tailings. The rethreshed tailings are entrained in the air stream formed by the blower and conveyed from the rethreshing assembly through duct work to the combine for reprocessing.

Abstract: A spreader for liquid or solid farmyard manure. The spreader comprises a manure container, an unloading rotor and a manure pusher. The rotor is spaced above the level of the bottom of the container and discharges over the rear wall of the container. The pusher keeps the rotor immersed in manure to the correct depth. In this way both solid and liquid manure can be spread. The rear wall of the container slopes up to the rotor to guide solid manure to the rotor.

Abstract: Torque limiting device especially applicable to the drive train to cane chopping apparatus in a sugar cane harvester. Abutments associated with the friction members of a band type clutch abut when slip occurs and trip an over-centre device to release the drive. About 360.degree. of slip can occur before the device trips. The drive is re-engaged by reversing the drive thereto.

Abstract: Butt lifter roller for lifting the butts of sugar cane sticks immediately after severing by the base cutter in a sugar cane harvester. The roller has V-shaped grooves of varying width extending round its periphery. Cane butts at least partially enter the grooves and are pinched or gripped therein and lifted over the roller by rotation thereof.

Abstract: Roller for feeding wholestick cane from the base cutters towards the can chopping apparatus in a sugar cane harvester. Cane engaging bars are mounted on a central shaft by means of curved leaf springs and accommodate themselves to variations in the thickness of the layer of cane fed, by deflection of the leaf springs.

Abstract: A harvesting and threshing machine having a crop collecting platform carrying a threshing cylinder extending across its full crop collecting width. Crop threshed by the cylinder passes to a straw conveyor mounted behind the cylinder which collects the threshed crop and conveys it laterally. The straw conveyor may itself effect grain separation or may pass the crop to grain separation apparatus.

Abstract: Chain and slat type elevator for pieces of chopped sugar cane in a sugar cane harvester has a slope of between 50.degree. and 90.degree. with respect to the horizontal. An endless belt of wire mesh above the working run of the elevator engages the cane pieces and prevents them rolling back.

Abstract: Combined harvesting and threshing machine which can be mounted as a compact single unit on the front of a self-propelled power unit. Crop is cut by a cutterbar and fed by an auger to a threshing cylinder at one end of a crop gathering table. The threshing cylinder discharges threshed crop onto the input end of straw walkers mounted above the cutterbar.
