Abstract
A lift arm assembly (30, 32) for a commercial riding mower includes pivotal lift arms (36, 38, 40, 120), each of which is biased downwardly by an adjustable spring arrangement for better control and contact between the underlying turf and the cutting reels supported on the outer ends of the lift arms.
