Abstract
The present disclosure provides systems and methods for power machines, including a mini-loader that includes a frame, an operator station positioned toward a rear end of the frame and configured to be used by an operator who is behind or on the rear end of the frame, and a power source positioned toward a front end of the frame.
Claims23
A mini-loader comprising:
- a frame;
- an operator station positioned toward a rear end of the frame and configured to be used by an operator who is behind or on the rear end of the frame;
- a power source positioned toward a front end of the frame;
- one or more hydraulic pumps operatively coupled to the power source;
- and
- at least two heat exchangers supported by the frame and configured to cool fluid passing through the at least two heat exchangers, including a radiator configured to receive coolant from the power source and an oil cooler configured to receive hydraulic fluid from the one or more hydraulic pumps,
- wherein the at least two heat exchangers are positioned between the power source and the operator station.

A mini-loader comprising:
- a frame;
- an operator station positioned toward a rear end of the frame and configured to be used by an operator who is behind or on the rear end of the frame;
- a power source positioned toward a front end of the frame;
- at least one heat exchanger supported by the frame to be positioned between the power source and the operator station, and configured to cool fluid passing through the at least one heat exchanger,
- an air inlet positioned toward a rear end of the frame;
- a hood pivotally coupled to the frame and configured to cover the power source and at least one side of the at least one-heat exchanger;
- at least one air outlet arranged on a first lateral sidewall of the hood or an opposing second lateral sidewall of the hood;
- and
- a fan coupled to the at least one heat exchanger and configured to draw air through an airflow path defined by the air inlet, the at least one heat exchanger, and the at least one air outlet.

A mini-loader comprising:
- a frame;
- an operator station positioned toward a rear end of the frame and configured to be used by an operator who is behind or on the rear end of the frame;
- a power source positioned toward a front end of the frame;
- and
- a hydraulic pump unit including one or more hydraulic pumps, the hydraulic pump unit being operatively coupled to the power source and extending from the power source towards the rear end of the frame, and the hydraulic pump unit being solely supported by a coupling with the power source.
2 more elements
A mini-loader comprising:
- a frame including a first side frame member, a second side frame member laterally opposite the first side frame member, and a cross member spanning between the first and second side frame members;
- an operator station positioned toward a rear end of the frame and configured to be used by an operator who is behind or on the rear end of the frame;
- and
- a power source positioned toward a front end of the frame and supported by engine mounts on each of the first side frame member, the second side frame member, and the cross member, the engine mounts including:
- a first engine mount coupled between a front side of the power source and the cross member and positioned in a vertical plane defined by a crankshaft of the power source;
- a second engine mount coupled between the power source and the first side frame member;
- and
- a third engine mount coupled between the power source and the second side frame member.
