Transmission made in Argo Tractors

Argo Tractors produce the new transmission, with mechanical or hydraulic reverse shuttle, 4 speed gears and 3 ranges to which two options can be added: Hi-Lo and High-Medium-Low, and finally creeper. Models can be 2 or 4 wheel drive. The new REX 4 Series offers a wide choice of power take-offs either mechanical or hydraulic versions, depending on the transmission, and with two or four speed (540, 540 Eco, 1000 and 1000 Eco).

Innovative hydraulic system for maximum flexibility

The REX4 comes with a variety of hydraulic options and configurations to offer farmers tailored solutions for their applications. The hydraulic system of the REX4 range comes standard with a double pump that supplies 50 l/min to the rear hitch and remotes and 28 l/min to the steering system. Optionally, it can be equipped with a triple pump that provides a flow rate of 44+41+28 l/m to operate, respectively, the rear hitch and remotes, the front remotes and the steering system. The tractor can be equipped with up to seven remote valves, four at the rear and three at the front. Available options include three electrohydraulic front remotes, a flow selector to control multiple outlets with a single control and a flow divider to regulate the flow rate to the remotes. The F and V models can be equipped with rear hydraulic stabilizers which control opening and closing of the lower links via two simple push-buttons. This function can be useful when attaching implements or when hitch adjustment during inter-row operation is required.
