摘要： An agricultural machine has a linkage system (12) for hitching of an implement and an additional axle 30 mounted to the linkage system. The linkage system comprises at least one lift arm adjustably mounted to the chassis at an inner end and carrying a fastening device at an outer end and. The additional axle (30) is connected to at least one lift arm in-board of the fastening device. The linkage assembly (12) may be a three-point linkage assembly having two lower lift arms, the additional axle (30) being mounted between the lower lift arms.

摘要： An internally reinforced thermoplastic container (12) has a body manufactured using rotational moulding. Prior to moulding, a number of attachment elements (18a, 18b, 18c, 18d) are releasably attached to the interior surface (28) of parts (26a, 26b) of a mould (24) and an initially separate tension member (20) is connected between the attachment elements (18). The mould (24) is closed and a body of the container (12) moulded such that the attachment elements (18) are integrated into the walls of the body. After moulding, the attachment elements (18) are released from the mould (24). The attachment elements (18) and the tension member (20) define a tension structure to resist outward bulging of the container walls. The tension member (20) may be tensioned prior to or after moulding of the container body. The attachment elements (18) may take the form of eyelets having a base (19b, Fig. 7) which is incorporated into the wall of the container body. The method enables the formation of a hollow thermoplastic container with integrally formed internal reinforcement.

摘要： In a tire (20) having a carcass (100), a tread, a bead, a shoulder, a sidewall and a first internal cavity, at least one stiffening line for a pressurized fluid with a second cavity is provided within the first cavity. The second cavity is aligned in an approximately transvers direction in regards to the periphery of the tire. The second cavity is connectable to pressurized fluid supply system and can be inflated or deflated to adjust the stiffness of the tire. The at least one stiffening line may be inflated using a hydraulic fluid.

摘要： A utility vehicle (10) such as an agricultural tractor includes an engine, a heat exchanger (26, 28, 30), and a fan (44) located under a bonnet (32). The bonnet is pivotable between a closed position (Fig. 2) and an open position. The fan (44) is mounted to the bonnet (32) such that, when in the closed position, the bonnet covers the engine and heat exchanger and the fan is positioned in an operable position to generate a cooling airstream through the heat exchanger. When the bonnet is in the open position the fan is displaced from the operable position.
