Description

Tractor The present invention relates to a tractor. More specifically, the present invention relates to a tractor in which a PTO is installed at the front to enable the connection of an implement, wherein the front shaft is a driving shaft and the rear shaft is a steering shaft. Generally, the rear of a tractor is equipped with three links, such as an upper link combined with an upper bracket and a pair of left and right lower links. Various types of agricultural implements, such as rotavators, fertilizer spreaders, rakes, and plows, are installed on these three links and driven by the tractor's power. These agricultural implements are structured such that a frame of a specific shape supports the entire element to facilitate easy installation on the tractor. The frame is equipped with an upper and lower link connecting structure to connect the upper and lower links provided by the tractor. The aforementioned prior art is disclosed, for example, in Korean Registered Patent No. 10-1532506 (Title of Invention: Connecting Device for Installing an Implement at the Rear of a Tractor). FIG. 1 is a drawing illustrating a connecting device for installing an implement at the rear of a tractor according to the prior art. In the prior art illustrated in FIG. 1, a rotavator is connected to the rear of the tractor. The tractor as illustrated in FIG. 1 is of a type where the front axle is the steering axle and the rear axle is the driving axle. However, depending on the implement, there are cases where installing it at the front of the tractor is effective for work efficiency. For example, when harvesting crops such as corn, work efficiency can be improved by having the implement pass first and the tractor pass afterward. The same applies to telescopic devices. If a telescopic device for lifting heavy loads is installed at the rear of the tractor, the operator cannot perform the work while observing the lifting status of the load, which reduces not only work efficiency but also safety. It is not impossible to install implements such as the harvester or telescopic device described above at the front of a rear-drive axle type tractor as shown in Fig. 1. However, since rear-drive axle tractors are designed with a PTO installed at the rear for power extraction based on the premise of installing implements at the rear, installing such a PTO at the front of the tractor in duplicate causes structural complexity and increases costs. As another solution, by making the driver's seat of a rear drive axle tractor rotatable and connecting implements such as the harvester or telescopic device described above to the rear PTO of the tractor, and then driving the tractor in reverse by rotating the driver's seat 180 degrees, it would be possible to achieve an effect similar to installing these implements at the front of the tractor. However, even in this case, providing a rotatable structure for the driver's seat would cause structural complexity and increase costs. The inventors arrived at the present invention after conducting repeated research on a tractor and implement installation structure specialized for work involving implements that are advantageous for front installation, by configuring the front axle of the tractor as a drive axle and the rear axle as a steering axle, much like a forklift, and providing a PTO to the front of the tractor. FIG. 1 is a drawing illustrating a connecting device for installing a work implement at the rear of a tractor of the prior art. FIG. 2 is a drawing illustrating a tractor (100) equipped with a front implement connection device according to one embodiment of the present invention. FIG. 3 is a drawing showing a tractor with a work implement installed on a front work implement connecting device according to one embodiment of the present invention, at a different angle from FIG. 2. FIGS. 4 and FIGS. 5 are drawings illustrating a tractor with a telescopic device installed in a front implement connecting device according to an embodiment of the present invention.
