    Abstract: A tractor steering and braking arrangement has a substantially vertically extending structural support column 11 for connection at a lower end 12 to a floor 13 of a tractor cab and carrying means 18 to support a steering wheel 15 at its upper end. At least one hydraulic master cylinder 29, 30 for operation of brakes of the tractor is supported within the column 11. The master cylinder 29, 30 includes an operating rod 27, 28 and an associated piston which is moved substantially vertically by an associated brake operating pedal 19, 20. The pedal is positioned at one side of the structural support column 11 and supported for pivoting from the column. Where separate left and right brakes are used, separate left and right master cylinders are mounted vertically within the support column 11. Both pedals are also mounted for pivoting from the column at a position 21 inside the column.

  • Publication number: 20140070569
    Abstract: An engine hood (10) for a tractor (1) or similar vehicle, the hood being of generally inverted U-shaped configuration with an upper top portion and downwardly extending side portions. The hood is hinged adjacent one end for upward pivoting between a closed position in which the associated engine is covered and an open position which provides access to the engine. The hood has an outer skin (100) and inner reinforcing members secured to the inside of the outer skin to form two beam- like structures (140, 141) which extend away from the hinge towards the other end of the hood to stiffen the hood against twisting. Inner reinforcing members extend between the beam-like structures to further stiffen the hood and the outer skin at the other end of the hood houses lighting units and has an inner reinforcing member extending between the beam-like structures which also supports the lighting units. The invention also provides a method of assembling such a hood.

  • Publication number: 20140062031
    Abstract: A rotary seal arrangement has a rotatable component (2) supported within a machine component (3), the machine component (3) forming a housing structure for a sealing means (23) which acts to seal off a high-pressure area (10) between the components (2,3) to allow the passage of high pressure fluid therebetween. The seal arrangement includes a holding element (30) for mounting in the machine component (3) to support spaced sealing members (23) therein to define said high pressure area (10) therebetween. The arrangement is particularly suitable for use where the rotatable component (2) is formed as a rotatable shaft and the holding element (30) and sealing members (23) are arranged around the shaft such as, for example, in a vehicle tyre pressure changing system for use on an agricultural tractor.

  • Publication number: 20130316771
    Abstract: A method of manufacturing cracker roller discs comprises forming a disc blanks and machining to produce the final form. The disc blank has an axial bore through the centre, a first portion radially outward of the centre of substantially constant thickness, a second portion radially outward of the first portion which second portion tapers towards the periphery of the disc blank, and a plurality of upstanding ridges extending radially outward across the second portion on opposed faces of the disc. Machining, suitably by turning on a lathe, removes the top part of each ridge and leaves at least one sharp edge extending along it, with all ridges on a face being machined in a single operation.

  • Publication number: 20130312401
    Abstract: A pressurised fluid supply system for an agricultural vehicle (100) includes a main supply circuit (MC) including a variable displacement pump (RP) providing a first source of pressurised fluid to a steering system (SS) of the vehicle and to consumers (WH) connected with the vehicle. A steering supply circuit (SC) includes a fixed displacement pump (LHP) supplying pressurised fluid to the steering system (SS). A pilot pressure circuit (PPC), connectable to supply a second source of pressurised fluid to consumers connected with the vehicle, receives pressurised fluid from the main supply circuit (MC).

  • Publication number: 20130284281
    Abstract: A tyre inflation feed arrangement for a tyre supported on a wheel carried by a wheel rim rotatably mounted via a wheel hub on an axially outer end of an axle housing. The feed arrangement has an annular support body surrounding the outer end of the axle housing, and three concentric annular seals extending around an axially outwardly facing surface on the support body to seal two concentric annular chambers formed in the axial!y outwardly facing surface between the seals. A first of these annular chambers is connectable with pressurised air to inflate the associated tyre and the second annular chamber is connectable with pressurised air to operate a valve mounted on the wheel for admitting air into the tyre from the first annular chamber or exhausting air from the tyre.

  • Publication number: 20130247527
    Abstract: A braking system for a rotating chopper drum (14) of a forage harvester (10) driven from an engine (11) via a drive train including a disengageable clutch (21). The drive train also drives a first pump (28) connected with the drum (14) which pumps fluid around a hydraulic circuit which includes an openable restriction (40). The system is arranged to brake the chopper drum (14) by disengaging the clutch (21) and arranging the first pump (28) to pump fluid around the circuit via the openable restriction (40) as the drum (14) continues to rotate to convert the energy of the rotating drum (14) into heat.

  • Publication number: 20120272779
    Abstract: A lever arrangement for use on an agricultural machine. The lever arrangement comprises a movement plate connectable to an actuation means. The movement plate is provided with guidance means for movement within a guidance track and the plate is moveable by means of a lever. Movement of the lever in one plane results in a first movement of the plate followed by a second movement of the plate. The first movement is a linear, or rotational movement of the plate and the second movement is a rotational, or linear movement of the plate different from the first movement.
