Abstract: An example snow blower machine includes a first stage snow mover and a second stage snow mover. Snow is received at an inlet opening of the first stage and expels snow to the discharge opening. In a second stage, an impeller chamber receives snow from the first stage. The impeller chamber extends from a snow receiving end proximate the discharge opening to a distal end rearward of the discharge opening. To receive expelled snow from the first stage and deliver the snow to a second discharge opening, an impeller rotatable around an impeller axis at a hub is disposed in the impeller chamber. The impeller may be rotated by an impeller motor having a motor body that is at least partially disposed within the hub.

Abstract: A hydraulic system for a machine includes a first pump, an implement pump, a control valve, and an auxiliary circuit. The first pump is configured to supply a first fluid flow to a first circuit, such as a steering circuit. The implement pump is configured to supply a second fluid flow to an implement circuit to actuate a primary implement function. The auxiliary circuit is configured to deliver fluid flow to actuate an auxiliary implement function. The auxiliary circuit is fluidly coupled to the implement circuit. The auxiliary circuit is also coupled to the first circuit by the control valve. The control valve is located downstream, in the direction of fluid flow, of the implement pump and the first pump. The control valve is configured to allow at least a portion of the first fluid flow to enter the auxiliary circuit and be delivered to the auxiliary implement function.
