Abstract
A control section selectively executes one of a first control and a second control when the accelerator opening degree is less than a first opening degree and a switching operation is performed by a forward and reverse switching operation lever. The control section controls a motor capacity control section so as to maintain the capacity of a hydraulic motor before and after the switching operation in the first control. The control section controls the motor capacity control section such that the capacity of the hydraulic motor is a minimum value which is set in advance at each speed level in the second control. The control section executes the first control when the temperature of the hydraulic oil is equal to or less than a first temperature and executes the second control when the temperature of the hydraulic oil is higher than the first temperature.
