A drift control method for a machine that includes a controller, a cutting tool, a motor having a motor shaft for driving a machine function, a control valve, and an operator control for commanding a machine function. The drift control method includes sensing a neutral position of the operator control, and when in the neutral position, further storing a first position of the motor shaft or cutting tool in the controller, detecting a change in position of the motor shaft or cutting tool with a sensor, determining a direction as a function of the change in position, and hydraulically controlling the motor shaft or cutting tool to the first position.

A hydraulic system that has a hydraulic pump connected to and in communication with a hydraulic motor, at least one hydraulic cylinder, or both by a first conduit and a second conduit (i.e., a high side and a low side). The hydraulic system has a bypass valve connected to and in communication with the first conduit and the second conduit. The bypass valve has a preset pressure that is above a minimum low side pressure. When a shock load occurs in the hydraulic system and a related drop in pressure on the low side occurs, the bypass valve opens when the preset pressure is passed thereby preventing the pressure from dropping to the minimum low side pressure. The hydraulic system thereby avoids a low loop event that could cause damage to the hydraulic system without the presence of larger charge pumps or accumulators.

A hydraulic motor has a primary side and a secondary side. A hydraulic pump is to be driven by the engine to supply an operation fluid to the primary side. A bypass circuit is to connect the primary side and the secondary side. An electromagnetic valve is configured to control a flowing amount of the operation fluid in the bypass circuit to control an amount of the operation fluid supplied to the primary side. A filter is disposed in a fluid tube connected to the secondary side. A relief valve is disposed between the hydraulic pump and the primary side. A controller is to control the electromagnetic valve to drive the hydraulic motor in a case where a temperature of the operation fluid is low when the engine is started.
