Abstract

PURPOSE: To prevent an unexpected engine stop by selecting a high speed and low speed hydraulic clutches with a control valve by a method wherein there are provided a high speed hydraulic clutch directly connecting a running propulsion aixs and a running transmittance axis of tractor etc. and a low speed hydraulic clutch for connecting both axes.
CONSTITUTION: When an excessive load is applied due to certain causes during a running operation of a tractor, a control valve is set at its low speed, the operation is changed from a high speed hydraulic clutch 34 as a low speed hydraulic clutch 35. Then, the operating oil is fed to the cylinder chamber 38. the piston 40 holds the clutch plate 46 against the receiving plate 42 to combine the driving disc 36 and the driven member 44 through the clutch plate 46 so that the low speed hydraulic clutch 35 is connected thereat. Therefore, a driving power from the running propulsion shaft 18 is transmitted to the running transmittance shaft 21 through the driving disc 36, clutch plate 46, driven body 44, gear 30, deceleration shaft 25 and gear 29 etc., and thereby decelerated in the gears 30 and 28, and gears 29 and 31 to prevent the engine stop.
