A pair of return fluid filters are supported within a main cavity of a hydraulic fluid reservoir for receiving fluid from the bottoms of respective return fluid cavities defined by a housing fixed to a top wall of the reservoir. Respective access covers close the cavities and are connected to the return fluid filters and to respective removable bottom plates of the cavities such that the filters may be withdrawn from the main cavity, via the return fluid cavities, for service or replacement. Each cavity is provided with a bypass valve which acts to bypass return fluid directly from the associated return fluid cavity to the main cavity in the event that the associated filter becomes clogged. Mounted on the housing in alignment with the bypass valves are respective switches which are respectively operated in response to movement of the bypass valves to their bypass position to energize a light to indicate the clogged filter condition to an operator.

The accoustic noise suppression apparatus is mounted opposite a radiator which is in fluid communication with a liquid cooled internal combustion engine having fan generated air flow through the radiator to encounter the noise suppression apparatus. The noise suppression apparatus is tri-sectional, each section including accoustic energy absorbing material. The noise suppression apparatus alter the flow path of the fan driven air flow, exhausting the air to the surrounding environment while decreasing the amount of accoustic noise received by the surrounding environment.
