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.

Exhaust systems for vehicles

A drive for a cooling fan at motor vehicles including a main cooling circuit and at least one secondary cooling circuit using a fluid friction clutch including a control element for the drive of the cooling fan is described. In case of a plurality of cooling circuits, such fluid friction clutches do not react as desired by actuating the cooling fan. To prevent this disadvantage, a drive for a cooling fan being drivable by a fluid friction clutch is to be provided, in which the cooling fan starts operation as soon as there is a requirement in at least one of the cooling circuits. For this reason, temperature sensors are allocated to selected secondary cooling circuits and further control element is allocated to the working chamber to bypass the control element, the control element freeing a further opening being located in the separating wall when predetermined temperatures and temperature ranges, respectively, are attained in at least one of the selected secondary cooling circuits, the opening not being influenced by the control element.

Liquid friction clutch

An arrangement of radiators () for a utility vehicle, e.g., an agricultural tractor, comprising three or more cooling radiators which together define a chamber (), optionally with some of the walls formed by perforated plates instead of radiator elements. One of the radiator elements may be pivotally mounted with respect to the others to provide access to the chamber. The arrangement of radiators may be mounted on a common support ().
