According to the present disclosure, a controller includes a base and a continuous sealing layer connected to the base forming an environmentally sealed compartment between the base and a lower surface of the continuous sealing layer. A circuit board is positioned within the compartment, and a rotary knob encoder is positioned on an upper surface of the continuous sealing layer. Movement of the rotary knob encoder is detectable by the circuit board through the continuous sealing layer.

A mechanical linkage for a power machine includes first and second horizontal shafts extending sideways along respective first and second axes. First and second links are operably coupled to the respective first and second horizontal shafts. The links convert actuation of operator input devices of the power machine into rotation of the horizontal shafts about their axes. First and second valve actuators convert rotation of the respective first and second horizontal shafts into actuation of respective first and second spools in a hydraulic valve of the power machine.
