The invention relates to tractors, in particular for the garden tractors with open work space.Known tractor having a safety rack, which can be omitted, and includes a tubular U-shaped, whose shoulders are connected to two opposite lateral sides of the tractor for rotation on a transverse axis between upper and lower positions, and that the La preventing movement of the safety rack of the pre-chosen position.The purpose of the invention to create a tractor, in which the safety rack can be quickly and easily raised or lowered without the use of tools, removing or installing any parts.To this end, each tool to install the safety rack includes a rod telescopically sliding in the corresponding shoulder of the tubular element and having siteplease the end, out of the end of the arm under the action of the elastic pressure means for engagement with the first or second slot, located on the corresponding side of the tractor at the moment when the safety stand is located respectively in one or the other position. The retaining means include a screw with a working head, which is screwed into a transverse hole in each rod, through the axial groove made in the appropriate shoulder. The screw is completely screwed in position is adapted to push on the internal wall of the shoulder, which is opposite to the axial groove.In another embodiment, each lateral side of the tractor case has a box-shaped device which is limited to the corresponding movable front panel on which the spotlight. This panel forward and an open position in which the spotlight is directed towards, in order to enable the safety rack to move between the upper (vertical) and lower provisions. To hold the movable panel in the closed position there are quick means of restraint.Fig;1 shows a lawn tractor, side view. safety stand in a vertical position; Fig.2 the same in the lower horizontal position; Fig. 3 view B in Fig.2; Fig.4 view In Fig.2; Fig.5 type G in Fig.4; Fig.6 section a-a of Fig;1; Fig.7 section d-D in Fig.6.Garden tractor 1 has an open workspace 2 and placed before him the safety rack 3, made with the possibility of lowering. Safety strut 3 is movable between the vertical (upper) position and a lower position where it is stretched forward horizontally outside the front of the tractor 1. Safety hour 3 consists of a tubular element in a U-shape, whose shoulders 4 are connected to two opposite lateral sides 5 of the chassis of the tractor 1. Each shoulder 4 of the safety rack 3 includes an outer tube 6 and the inner tube 7. Near the free end of each arm 4 pipes 6 and 7 are matched with the first element 11, attached to the respective lateral side 5 of the body of the tractor.In the inner pipe 7 telescopically sliding rod 12, which at its lower end has a shank 13 with a rounded terminal part 14, on which the locking element 15, made for example of rubber. Above the shank 13 of the rod 12 has a tubular shape and two opposite axial slot 16, through which passes an axial bolt 10. In the upper part of the rod 12 is fixed a cylindrical frame 17, which has a threaded through hole 18, into which is screwed the screw 19. The screw 19 at one end has a tip 20 for engagement with the inner wall of the inner tube 7, and the opposite end passes through two axial groove 21 and 22 located respectively in the inner tube 7 and the outer tube 6. The screw 19 is attached operated working cylinder 23 that extends from the inner side of the arm 4.On the upper part of the cylindrical frame 17 posted by helical compression spring 24 acting to its lower end as shown in the drawing, a bearing surface on the inside of the shoulder 4, which will cause the rod 12 to occupy a pre-eminent position. Rounded end portion 14 and the locking element 15 out of the shoulder 4.When the safety strut 3 is in the upright position, end portion 14 of each rod 12 engages into the slot 25, the stopper member 15 rests on the base of the box-shaped device 11. Each rod 12 is locked in the direction of the axis relative to the corresponding shoulder 4 by screwing the respective screw 19, resulting in the tip 20 is e engagement of their trailer device 29 in the respective exciting apparatus 30.Thus, the safety hour 3 protects the driver of the tractor 1 in case of inversion. In addition, it can be used to secure any flexible top to protect the workplace.In order to move the safety rack 3 from a vertical position to the bottom position, you need to move the panel 27 from the closed position into the open. Then enough visibility two screws 19 through the use of head 23, to allow the rod 12 to slide relative to the shoulder 4. At this point, the rack 3 is pushed forward to release the terminal part 14 of the slots 25, freeing them from the action of the springs 24, and then stand 3 can be moved into the lower position. When the turn is completed, the terminal part 14 engage in other sockets 26, thereby securing the rack 3 in the lower position. In order to securely lock the rack 3 in this position, enough to fully tighten the two screws 19 through the respective heads 23. In order to return the safety rack 3 in a vertical position, the above-described methods are repeated in reverse order.Usually the details of construction and forms of implementation may vary. So, Nancy and/or electric auxiliary power actuators acting sequentially or independently. 1.
