Embodiment Construction

[0019] figure 1 A power lift 10 is shown, which is mounted on a rear region 12 of an agricultural tractor 14 . A power lift 10 in the form of a three-point implement hitch includes a support structure 16 mounted on a farm tractor 14 to which left and right lower links 18, 20 and a central upper link 22 are pivotally mounted. superior. Both the lower links 18, 20 and the upper link 22 have corresponding couplings 24, 26, 28 at their free ends for mounting an agricultural mounted implement (not shown). The coupling elements 24 , 26 , 28 arranged on the lower link 18 , 20 or the upper link 22 are formed by detachable grapples for receiving corresponding coupling points 30 , 32 , 34 of the agricultural suspended implement. Rather, the agricultural mounted implement has a so-called A-frame 36 with left and right lower coupling points 30 , 32 and a central upper coupling point 34 . The coupling points 30 , 32 , 34 are now formed by engagement balls corresponding to the gripper ho...

Abstract

A power lift (10) for an agricultural tractor (14) includes a supporting structure (16) configured to be mounted on the agricultural tractor (14). A left lower link (18), a right lower link (20), andan upper link (22) are mounted on the supporting structure in a pivotally movable manner, wherein the left and the right lower links (18, 20) and the upper link (22) include coupling elements (24, 26,28) for attachment of an agricultural attachment. The left and the right lower links (18, 20) are rotatably coupled to one another via a lifting shaft (40), the lifting shaft being aligned with a lower link pivot axis (38). The left and the right lower links (18, 20) are pivotable by an actuating element (42, 44) which runs between at least one of the lower links (18, 20) and a support point (46,48) of the supporting structure (16) jointly about the lower link pivot axis (38) in relation to the supporting structure (16).

Description

technical field [0001] The present invention relates to a power lift for agricultural tractors, having a support structure mountable on the agricultural tractor, on which support structures are rotatably mounted left and right lower links and a center The upper connecting rod, wherein the lower connecting rod and the upper connecting rod have corresponding coupling pieces for installing agricultural suspended agricultural implements. Background technique [0002] Such power lifting devices are widely circulated in the form of three-point implement hangers on agricultural tractors. Most of the power lifting devices installed in the rear of agricultural tractors include a hydraulic lifting mechanism with left and right hydraulic lifting cylinders for pivotal operation corresponding to the lifting arm which is mounted by means of a lifting shaft installed in the rear of the agricultural tractor Rotate each other. Lifting struts are respectively installed at the free ends of t...
