Abstract

A mining machine includes a frame, a first fluid tank, a second fluid tank, a valve, and a control system. The first fluid tank is supported on the frame proximate a first end, and the second fluid tank is supported on the frame proximate a second end. The valve permits fluid communication between the first and second fluid tanks when the valve is in a first position, and prevents fluid communication between the first and second fluid tanks when the valve is in a second position. The control system includes a first sensor detecting an amount of fluid in the first tank, a second sensor detecting an amount of fluid in the second tank, and a controller. The controller moves the valve to the first position when the difference between the amounts of fluid in the first and second tanks a predetermined threshold.
