摘要： A tractor for use with a front loader connected thereto has a pair of mast mounts for detachably attaching right and left masts of the front loader, a pair of braces for coupling the mast mounts to the tractor, and a weight mount for carrying a plurality of weights. The braces have distal ends thereof connected to the weight mount. A spacing L1 between the distal ends of the braces is smaller than a spacing L2 between proximal ends thereof. Consequently, the braces are arranged to avoid their interference with front wheel steering. With the weight mount acting also as a brace support, the weight mount has an increased supporting strength.

摘要： A self-propelled vehicle with a loader comprises a vehicle body extending in a fore and aft direction of the vehicle; support bases extending laterally outwardly from opposite sides of the vehicle body; main frames erected on the support bases, respectively, each main frame being in form of a box opening forward and upward and including right and left side walls and a rear wall, the box containing an engageable element; side frames each mounted in the box, each side frame having an engaging element disposed in a lower region thereof for rotatably fitting from above on the engageable element; booms pivotably connected to upper end regions of the side frames, respectively; boom cylinders for swinging the booms relative to the side frames, respectively; and reinforcing members each disposed between the right and left side walls of one of the main frames. Each reinforcing member has a front reinforcing portion extending upward from one of the support bases, a rear reinforcing portion disposed rearwardly of a lower portion of one of the side frames and extending above the engageable element, and an intermediate reinforcing portion interconnecting an upper end of the front reinforcing portions and a lower end of the rear reinforcing portion.

摘要： An apparatus for controlling the posture of a front loader has booms attachable to a vehicle body which are pivotally movably upward and downward and has a work implement attached to the forward ends of the booms and pivotally movable in a scooping direction and a dumping direction. Each of the booms and the implement are pivotally movable by a single control lever independently of each other or movable simultaneously. The apparatus includes an actuating member for shifting the control lever from a boom raising position to a boom raising and dumping position when the booms are not positioned lower than a specified level. This eliminates the likelihood of the implement tilting rearwardly downward even if the booms are raised, precluding the implement from spilling the earth or sand scooped up.

摘要： A device for attaching a front loader to a tractor by removably mounting each of a pair of boom supporting masts on a mast support fixed to the tractor body and removably fixing the front end of each brace extending forward from the mast to a brace fixing member secured to the front end of the tractor body. One of the lower end of each mast and the upper side of the mast support has a projection, and the other of these parts has a recessed portion for receiving the projection. The mast is pivotably supported by means of the projection and the recessed portion from below while being thereby restrained from moving longitudinally of the tractor body. A guide on the brace end and the fixing member coact to hold the brace end in position. The mast and the brace are fixed in position by a lockpin. The loader can be removably attached to the tractor with ease and high rigidity.
摘要翻译：一种用于通过将一对起重臂支撑桅杆中的每一个可移除地安装在固定到拖拉机主体的桅杆支撑件上并将可拆卸地固定在从桅杆向前延伸的每个支架的前端到固定的支架固定构件的装置上，到拖拉机身的前端。每个桅杆的下端和桅杆支架的上侧之一具有突起，并且这些部件中的另一个具有用于接收突起的凹部。桅杆通过突起和凹部从下方枢转地支撑，同时由此被限制在拖拉机主体的纵向移动。支架端部和固定构件上的引导件将支架端部保持在适当位置。桅杆和支架通过锁扣固定在适当的位置。装载机可以轻松，高刚性可拆卸地连接在拖拉机上。

摘要： The posture of a front loader attached to a vechicle body is controllable by an apparatus which comprises an engaging portion provided on a control lever, an engageable member pivoted to a fixed member on the vehicle body and releasably engageable with the engaging portion when the control lever is positioned for lowering the boom of the loader and for moving the work implement of the loader for scooping, an implement sensor for detecting whether the angle between the implement and the boom is an angle which provides contact of a work implement bottom surface parallel with horizontal ground, and a release interlocking mechanism operatively connected to the sensor and to the engageable member for moving the engageable member to a released position where the member is not engageable with the engaging portion upon the sensor detecting that the work implement is at the angle.
