Abstract: A method for operating a power take-off shaft of an agricultural tractor with an attachment hoist includes providing a power take-off shaft spatially assigned to the attachment hoist, a hoist controller and a control unit. The method also includes detecting an operating state of the power take-off shaft via a first sensor and an upper operating position of the attachment hoist via a second sensor. The method further includes restricting the upper operating position to a first maximum value by the control unit if the first sensor detects that the power take-off shaft is not operating, and restricting the upper operating position to a second maximum value by the control unit if the first sensor detects that the power take-off shaft is operating, where the second maximum value is less than the first maximum value.

Abstract: A trailer device for an agricultural vehicle includes a frame part and a guide part longitudinally, displaceably mounted in the frame part. The guide part includes a coupling element provided on an end face. The frame part is pivoted by a lifting apparatus for raising and lowering the coupling element relative to a base frame for attaching to a load-bearing vehicle structure. The device includes at least one spring element arranged between the base frame and the frame part such that the spring element exerts a pretensioning force on the frame part for assisting the raising of the coupling element.

Abstract: A vehicle canopy comprises a stationary support bar that has substantially vertical base sections, tilted vertical sections tilted at an angle with respect to the respective base sections. A horizontal section extends between the tilted vertical sections. The horizontal section or the stationary support bar has a first peak height. A set of subsidiary stationary support bars is connected to the vertical base sections of the stationary support bar. The subsidiary stationary support bar has a second peak height less than the first peak height. A first support member has a set of mounting plates mounted above corresponding vertical base sections of the stationary support bar for supporting the first support member. A set of mounting flanges is on the subsidiary stationary supports. A second support member is supported by the mounting flanges.

Abstract: A bracket for mounting an electronic assembly comprises a base bracket for connection to a generally horizontal member or stationary support bar of a vehicle. A back member is coupled to the base bracket by one or more isolators. The back member has a set of first holes arranged in generally vertical array. A guide rail is attached to the back member. A slidable member is adapted for slidably engaging the guide rail. A support member comprises a shelf for supporting the electronic assembly and a support portion connected to the slidable member.

Abstract: A first guide rail extends substantially laterally on the vehicle. The first guide rail has a central slot for lateral adjustment of a base member. The base member is slidable or movable along the first guide rail until secured by one or more fasteners. A back member is coupled to the base member by the one or more isolators. The back member has one or more holes arranged in generally vertical array. A second guide rail is attached to the back member. A slidable member is capable of slidably engaging the second guide rail for releasing the electronic assembly or for adjusting a vertical adjustment of a height of the electronic assembly. A support member comprises a shelf for supporting the electronic assembly and a support portion connected to the slidable member.
