A tire inflation feed arrangement for a tire 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 axially outwardly facing surface between the seals. A first of these annular chambers is connectable with pressurized air to inflate the associated tire and the second annular chamber is connectable with pressurized air to operate a valve mounted on the wheel for admitting air into the tire from the first annular chamber or exhausting air from the tire. The annular seals are each mounted in a respective annular groove in the axially facing surface and each groove is also connectable with a source of pressurized air to press the seals against an annular contact surface on the wheel hub to seal the first and second annular chambers when the tire is being inflated. The wheel hub is provided with first receiving means which open through the annular contact surface to receive air from the first annular chamber and conduct such air to the tire and second receiving means which also opens through the annular contact surface to receive air from the second annular chamber and conduct such air to the valve mounted on the wheel. The support body is mounted on the axle housing in a location radially within bolts which attach the wheel to the hub to reduce the rubbing speed of the seals on the contact surface to reducing wear caused by the contact pressure of the seals.

Rotary joint

A tractor has a chassis () which supports an engine () towards the front thereof. A deflecting shield () is positioned to the rear of the engine to deflect sideways hot air which has passed over the engine, and a tank () for the storage of urea based fluid for injection into an exhaust system of the engine is located behind the engine to the rear of the deflecting shield. The chassis to the rear of the engine may have an open-topped section () between the engine () and a transmission housing (), the tank being at least partially housed within the open-topped section of the chassis to shield the tank from the hot air which has passed over the engine and from the heating effects of the sun.

Tractor

An exhaust system for an agricultural and/or industrial tractor () having an internal combustion engine () located in an engine compartment covered by an engine hood (). The system includes an exhaust gas treatment unit () located inside the engine compartment hood and having a main chamber () fed by an inlet pipe () which receives exhaust gases from the engine and an outlet pipe () which passes treated gases into a final portion () of the exhaust system. The inlet and outlet pipes () are non-aligned and extending alongside the main chamber () in opposite directions to reduce the overall length of the treatment unit. The treatment unit () may be installed above the engine () with the exhaust gases passing through the unit either generally normal or parallel to the direction of driving (D) of the tractor.
