Technology: 2 Speed
Change steering speed on the fly in tractors, backhoes, loaders, combines and other machinery with two-speed technology from Eaton. Depending on the application, operators can now easily switch between two metered steering modes to increase their productivity. Available on the Series 10 Steering Control Unit (SCU), two-speed technology offers intuitive, efficient and precise steering with minimal operator effort, and manual or emergency steering in unpowered mode for increased safety and control. See Applications for steering mode details.

1Typically, the gerotor between the SCU housing and the shift valve is the smaller gerotor (first gerotor). The shift valve is activated by the operator, which allows or prevents flow to the second gerotor. A separate solenoid valve provides the pressure pilot signal to shift the aforementioned valve. The OEM will define and provide the operator switch to activate the solenoid valve. Metered Steering Mode 1 – The steering unit operates the same as a traditional hydrostatic steering control unit. Steering (flow) is a function of steering wheel rotations (rpm). Metered (gerotor) steering provides precise, responsive, and smooth steering. All the flow is metered by the first gerotor, resulting in a greater number of turns lock-to-lock. In case of pressure loss, the shift valve automatically prevents flow to the second gerotor and emergency steering is available via the first gerotor. Metered Steering Mode 2 – The steering unit operates the same as a traditional hydrostatic steering control unit, except the flow is metered for a combined displacement of two gerotors. As with Mode 1, steering (flow) is a function of steering wheel rotations.As the total displacement per rotation is the sum of the two gerotor displacements, the number of turns lock-to-lock may be significantly decreased. Operator effort is greatly reduced during the work cycle. The number of turns lock-to-lock could go down to 0.5, where the ratio of the two gerotor displacements could vary from 1:1 to as high as 5:1, providing great flexibility in the design.
