Abstract
A filter assembly for a hydrostatic transaxle comprising a hydraulic pump and a hydraulic motor in fluid communication via porting formed in a center section. The filter assembly includes an upper filter member having a generally horizontally oriented filter media adapted to be positioned adjacent to the center section. A lower filter member is attached to the upper filter member to form a filter housing having an interior area such that make-up fluid enters the interior area substantially via the filter media. A conduit places the interior area of the filter housing in fluid communication with the porting of the center section through which make-up fluid is allowed to enter the porting of the center section.

A filter assembly for a hydrostatic transaxle comprising a casing in which is carried a hydraulic pump and a hydraulic motor in fluid communication via porting formed in a center section having a pump running surface on which the hydraulic pump rotates and a motor running surface on which the hydraulic motor rotates, the filter assembly comprising:
- an upper filter member having a generally horizontally oriented filter media adapted to be positioned adjacent to the center section;
- a lower filter member attached to the upper filter member to form a filter housing having an interior area such that make-up fluid enters the interior area substantially via the filter media;
- and
- a conduit placing the interior area of the filter housing in fluid communication with the porting of the center section through which make-up fluid is allowed to enter the porting of the center section.
