る。[Detailed description of the invention] Conventionally, deep tillage equipment, which is small but can be used not only for normal tillage but also for deep tillage like upside down, is equipped with long tilling claws attached to the tillage shaft in order to deepen the tillage depth. In this case, the tilling claws will come into contact with the rotary cover, so it is necessary to widen the distance between the rotary cover and the tilling shaft.This can be done by replacing the transmission case of the tilling device, or by inserting a spacer in the middle of the transmission case. There are two methods: a method in which the rotary cover is moved up and down relative to the transmission case using parallel links, a method in which holes are provided in the transmission case in two stages (upper and lower), and the rotary cover is replaced vertically. Are known.

1 has a mounting bracket 2 at the rear and a PTO shaft 1a.
The tilling device 3 is equipped with a machine frame 4 made up of two plates with the plate surfaces facing in the vertical direction, and a tilling shaft 5 extending to the left and right sides at the bottom. It consists of a transmission case 6 that hangs diagonally backward, and a rotary cover 7 that extends from the bottom of the transmission case 6 to both sides, and the tilling shaft 5 has long and short tilling claws 8 that can be replaced. The input shaft 9 of the transmission case 6 is attached to the yoke 10.
It is interlocked and connected to the PTO shaft 1a via a universal joint 11 having a.

ができる。 When adjusting the plowing depth as described above, the plowing depth can be easily adjusted to standard plowing depth or deep plowing by simply moving the lift arm 13 up and down using the hydraulic device 14a included in the tractor. The angle between the yoke 10 of 11 and the PTO shaft 1a or the angle between the input shaft 9 of the transmission case 6 is θ 1 = θ 2 , θ 1 ′ = θ 2 ′ as shown in FIG. 5, which reduces vibration and noise. Smooth transmission can be performed without causing any noise.
