摘要： Stabilizer for a lower draft link of a three-point hitch of a tractor, the stabilizer comprising a first stabilizer member and a second stabilizer member which is movably connected to the first stabilizer member by a spring-loaded centering mechanism, wherein the second stabilizer member can be rotated with regard to the first stabilizer member to modify the overall length of the stabilizer. A locking bracket is pivotally connected to the first stabilizer member for blocking a rotation between the stabilizer members by engaging the locking bracket with a blocking groove formed in a circumference of the second stabilizer member. Furthermore, a locking cover is provided for disabling a movement between the stabilizer members in a closed position. A section of the locking cover is faced to the locking bracket, wherein the section is formed such in that the locking bracket can be removed from the blocking groove for releasing a rotation of the second stabilizer member even in the closed position of the locking cover.

摘要： A drawbar support assembly includes a rail member attached to a hitch frame, a slider member and a drawbar support. The slider member is slidable in the rail member. The drawbar support has rollers which rollingly engage the slider member so that the drawbar is swingable laterally. The rail member includes a forwardly facing curved slot which slidably receives the tabs which project from the slider member. A spring unit is coupled between the rail member and the slider member and operates to urge the slider member to a central position relative to the rail member.

摘要： A stabilizer (1) for a link of a three-point suspension system of an agricultural tractor has at least one telescope (8) consisting of a tube (5) and a piston (6). Said tube and piston are coupled elastically by at least one spring (7) and can be adjusted in length by means of threads (12, 13). At least one retaining clip (15) which can engage over an abutment (17) is held pivotably on the tube (5). To increase the load-bearing capacity of the stabilizer (1), the stop surfaces (18) of the retaining clip (15) are connected in a tensionproof manner by means of at least one bridge (30). Said bridge (30) engages over the outer side of at least one contact surface of the abutment (17) by means of the stop surface (18).

摘要： The invention relates to a side strut (6) for the lower steering arm of a three-point hitch of a tractor. Locking catches (24, 25) are provided to cancel the floating position which the two telescopic members (14, 15) of the side strut 6 may assume relative to each other. The catches (24, 25) lock the members via locking contours (29, 30) of a locking recess 28, which surround and secure to a locking journal (31). The two locking catches (24, 25) are arranged at the sides of the telescopic members (14, 15). The locking catches have their pivot axis of the articulated journal (27) the points of contact between the locking contours (29, 30) and the locking journals (31), in a locked position, positioned on a connecting line. The line extends parallel to the sliding axis (16) and through the pivot axis of the ball eye (13). In this way, it is ensured that the locking catches (24, 25) and also the side strut (6), together, are not subject to any bending moments resulting from any tensile or compressive forces.

摘要： The draft links of a tractor carry clamplike bumpers which contact sway blocks mounted on a drawbar support on the opposite sides of the power takeoff housing. Each bumper is eccentric and tapered with respect to the longitudinal axis of the associated draft link and is clampable in positions spaced 180* about the axis to provide sway control for different hitch spacings or categories and is shiftable along the draft link to provide minor lateral adjustment.

摘要： A stabilizer for a tool bar hitched in draft relation to a tractor comprising a support mounted on the tool bar and extending forwardly therefrom alongside a rear wheel tire of the tractor, and a rotary element journaled for rotation on the forward end of the support to bear against and roll along side of the tractor tire to prevent lateral movement of the tool bar. Tool bars carrying ground breaking, planter implements or the like are generally mounted at the rear end of a two or three point hitch carried by a draft tractor. Such hitches are pivoted at their forward ends to the tractor on horizontal axes for raising and lowering movement of the tool bar. So mounted the tool bar is subject to a certain amount of lateral play. This is not particularly significant when the tractor and implement are travelling over level ground. However, on sidehill terrain the implement will tend to drift to the downhill side. This can be partially prevented by mounting a colter-type wheel on the tool bar for penetrating rolling engagement with the ground. However, it is found that such a wheel or wheels will tend to depart from a straight path behind the tractive vehicle in sidehill travel due to the laterally sliding implement weight making it difficult to carry the tool bar and its attached implements in straight parallel rows.
