Abstract

A device for front-mounting of an implement (11 ) on an implement- carrying vehicle has a supporting frame (13) from which the implement is suspended via two suspension arms (16). The suspension arms are connected, pivotally about a transverse axis (24), to the supporting frame (13) and are, thus, pivotable between a first end position, which is a stop position, and a second end position. The centre of gravity (25) of the unit suspended from the supporting frame (13) and consisting of the complete implement, including the suspension arms, is located in front of the pivoting axis (24), whereby the suspension arms (16), as the supporting frame pivots from a lowered position, in which support wheels (19) located at the front ends of the suspension arms abut against the ground (18), to an elevated position, are being automatically pivoted by the weight of said unit relative to the supporting frame (13), from the second end position to the stop position, so that the implement (11 ) is raised at its rear portion. As the supporting frame (13) pivots from the lowered position to the elevated position, the suspension arms (16) reach the stop position before the supporting frame reaches the elevated position, whereby the support wheels (19), as the supporting frame continues its pivoting movement to the elevated position, are being raised from the ground (18).

Abstract

A belt pulley device (12) is adapted to be mounted on a garden tractor for rotating, together with a horizontal first belt pulley (5) and an endless V- belt (8), a substantially horizontal second belt pulley (9) for driving of an im¬ plement mounted on the front of the tractor. The first belt pulley (5) is located at a higher level than the second belt pulley (9). The belt pulley device (12) is adapted to guide one run (8a) of the V-belt (8) that runs out from the first belt pulley (5) from the higher level down to the lower level and to guide the other run (8b) of the V-belt (8) that arrives at the first belt pulley, from the lower level up to the higher level. The belt pulley device (12) has a frame (13), which is adapted to be attached to the tractor and which supports two guide belt pulleys (21 a, 21 b), which, with the frame attached to the tractor, are tilted in such a manner relative to a vertical plane parallel to the longitudinal direction of the tractor that they form together an upwardly open V-shape, and are located slightly behind the first belt pulley (5) with their upper portion being on a level therewith and with their lower portion being on a level with the second belt pulley (9). A garden tractor is provided with a belt pulley device of this kind.

Abstract

The invention relates to an implement carrier (1 ), which comprises fastening means (5) for mounting an implement at the front. At least one of the fastening means (5) comprises a sleeve part (11 , 15), which is attached at a first point of attachment on the implement carrier (1 ) and is pivotable about the same. The fastening means has an implement fastener (19), to which an implement can be fastened, the implement fastener being pivotally attached at a second point of attachment on the sleeve part. The sleeve part (11 , 15) can be operated by rotating using an actuator part (27) so that the implement fastener is moved backwards, and a driving belt between the implement carrier and the implement is slackened, whereby the driving belt can easily be removed.

Abstract

An implement carrier has at least one pair of wheels (4a) which is driven by a hydraulic motor (8) included in a closed hydraulic line system (9) , which also comprises a hydraulic pump (10) which is adapted to drive the hydraulic motor and which is driven by an internal combustion engine (6) . The implement carrier has an actuator (5) , which only in an active position allows start of the internal combustion engine (6) . A bypass valve (16) arranged in the hydraulic line system (9) is settable between a bypass position, in which movement of the implement carrier is possible when the internal combustion engine (6) is shut off, and a normal position, in which such movement is impossible. The actuator (5) is connected to the bypass valve (16) in such a manner that the actuator when moving from an inactive position to the active position, if the bypass valve is in its bypass position, moves the bypass valve to its normal position.
