The present invention relates to a driving hydraulic circuit for a small power sprayer to be driven by using a hydraulic motor. More specifically, the present invention relates to a driving hydraulic circuit for a small power sprayer to improve driving ability to achieve satisfactory driving performance by using a remote controller at a distance to prevent driving performance from decreasing during driving using oil pressure. The driving hydraulic circuit for a small power sprayer to improve driving ability according to the present invention comprises: a driving hydraulic transmission which is connected to a driving engine and includes a driving closed circuit type hydraulic pump for supplying oil pressure； a driving hydraulic motor which is driven by oil pressure drawn from the driving hydraulic pump, and includes a first driving hydraulic motor and a second driving hydraulic motor which are installed in correspondence with a first driving wheel and a second driving wheel, respectively； a driving variable hydraulic valve which includes a first driving variable hydraulic valve and a second driving variable hydraulic valve which are installed at the first driving hydraulic motor and the second driving hydraulic motor, respectively, and controls the direction of oil pressure through a controller； and a driving hydraulic pipeline which guides the oil pressure drawn from the driving hydraulic pump. The driving variable hydraulic valve adjusts the direction of the oil pressure supplied to the first driving hydraulic motor and the second driving hydraulic motor. In the flow of the oil pressure during straight driving, the first driving hydraulic motor is connected to the second driving hydraulic motor in series, the oil pressure supplied to the first driving hydraulic motor is the same as the oil pressure supplied to the second driving hydraulic motor.본 발명은 유압모터를 이용하여 주행하도록 이루어진 소형 동력분무기용 주행 유압회로에 관한 것이다.상세하게는 유압을 이용한 주행시 발생하는 주행능력의 저하를 방지할 수 있도록 하여 원거리에서 리모컨을 이용하여 원활한
