Many systems in the Monarch Tractor MK-V rely on hydraulic fluid. To provide enough pressure for the demands, the tractor has a settling tank that provides storage for the 12 gallons on board. Follow the interval described in Scheduled Maintenance to see how frequently you need to change the hydraulic fluid.
Drain and Replace Hydraulic Fluid
