摘要： A hydraulic circuit for controlling the deck swiveling speed of a working vehicle comprises a hydraulic actuator for driving the swivel deck, a flow control valve for controlling a rate of oil flow to the hydraulic actuator, and a direction control valve for switching an operating direction of the hydraulic actuator. The flow control and direction control valves are operatively connected to a swivel control lever. The greater amount of swivel control lever is operated toward a right or left swivel position, to the greater extent the flow control valve is shifted in a flow increasing direction. The direction control valve is operable to switch oil lines in response to an operation of the swivel control lever.

A parallel oil passage having a restrictor extends parallel to a center oil passage of the swiveling valve section. The front implement valve section also receives pressure oil from the center oil passage of the swiveling valve section and the parallel oil passage. A load sensing system controls flow amounts of the first and second pumps according to a hydraulic load generated in a front implement operation.
