It is equipped with important equipment such as hydraulic control equipment and sensors such as hydraulic pipes and solenoid valves for the lift arm. For this reason, in the past, clods of earth, straw, stumps, etc. that adhered to the rear tires and were carried around between the transmission cases adhered to these devices, often damaging them and hindering field work. It was hot. Therefore, we install a separate protective cover, but since there are cases where the front loader's hydraulic outlet is also installed near this cover, and the shape becomes complicated, the equipment is completely covered and protected. The reality is that it is difficult to do so.

として使用することができる。 Even if clods, straw, stumps, etc. stick to the rear tires 15 in wet fields and are lifted from behind,
The lower support 19, which is provided within the left and right width of the fender 6 and below the fender 6, is extended to the rear wheel 3 side because the mounting seat 21 provided at its upper end will be located above the rear wheel 3. A plate 22 for reinforcing the mounting seat 21 projects and faces the upper surface of the rear wheel 3,
The lifted earth clods and the like are reliably scraped off by the plate 22. Further, the lower support 19 attached to the side surface of the mission case 8 extends diagonally upward to the rear of the mission case 8 at an angle of approximately 60 degrees, and the mounting seat 21 is located at the upper end of the lower support 19. Since it is welded to the mounting seat 21
The soil clods etc. scraped down by the plate 22 protruding from the rear wheel 3 fall directly onto the field behind the transmission case 8 from about 30 degrees before reaching the top dead center of the rear wheel 3. Therefore, even if devices such as hydraulic control equipment are installed on the sides of the transmission case 8 and the oil case 9 near the rear wheels 3, clods of earth, straw, stumps, etc. may adhere to the rear tires 15 and cause damage. It will not be passed around and attached to these devices. In addition, if the removable upper support column 18 is removed, the reinforcing plate 2
The lower support 19 to which the mounting seat 21 reinforced with 2 is welded can be used as a mounting frame for various devices such as a seeding device.

るものである。Effects of the Invention In short, the present invention provides a safety frame for an agricultural tractor in which an upper strut with a sunshade hood attached to cover the area above the driver's seat is attached to the fuselage side and fixed to a lower strut. A lower strut extending diagonally upward from the rear of the transmission case from the aircraft side is provided within the left and right width of the fender and below the fender, and a mounting seat is provided at the upper end of the lower strut to connect the upper strut. , the lower end extends toward the rear wheel so that it is close to the rear wheel, and the mounting seat is provided with a plate that protrudes toward the upper surface of the rear wheel. The mounting seat that connects the upper support provided at the upper end of the lower strut is located above the rear wheel, so the plate attached to the mounting seat that extends toward the rear wheel faces the top surface of the rear wheel. It is possible to reliably scrape off clods of soil etc. that have been lifted up by the rear wheels. Therefore, even if devices such as hydraulic control equipment and sensors are installed on the side of the transmission case or hydraulic case in close proximity to the rear wheels, the lower support of the safety frame must be used effectively. This prevents clods, straw, stumps, etc. from being carried around by the rear wheels and attaching to these devices, allowing for smooth field work.
If the upper strut is removed, the lower strut on which the mounting seat is formed can be used as a mounting frame for a seeding device, etc., which brings about extremely useful practical effects.
