Abstract

A machine includes a first cylinder coupled to a first wheel and a second cylinder coupled to a second wheel. A first proportional dampening valve fluidly connects to the first cylinder and a second proportional dampening valve fluidly connects to the second cylinder. First accumulators are fluidly connected to the first cylinder and the first proportional dampening valve, and second accumulator(s) are fluidly connected to the second cylinder and the second proportional dampening valve. Additionally, a first proportional flow control valve fluidly connects to the first cylinder and a second proportional flow control valve fluidly connected to the second cylinder. An electronic control module (ECM) communicatively couples to the first proportional flow control valve and the second proportional flow control valve to adjust a ride height of the first wheel via the first cylinder and a ride height of the second wheel via the second cylinder.
