Hydraulic transaxle

A transaxle, comprising:

• a transaxle casing with a fluid sump;
• an upper casing member that is detachably joined to the transaxle casing at an upper portion of the transaxle casing, the upper casing member defined by an upper wall and a sidewall joined to the upper wall;
• a hydrostatic transmission disposed in the transaxle casing;
• a reduction mechanism disposed in the transaxle casing;
• and
• at least one axle disposed in the transaxle casing;
• wherein the upper casing member accommodates a part of a gear of the reduction mechanism,
• wherein an air sump is formed inside the upper casing member,
• wherein the upper casing member comprises a hole opened on the upper wall facing the air sump, the hole arranged at a position separate from a point above the gear,
• wherein the upper casing member comprises a breather attached at the hole that allows outside air to flow into the upper casing member and is configured to block a flow of fluid into and out of the upper casing member,
• wherein the upper casing member comprises a first inner wall disposed inside the upper casing member and extending downwards from the upper wall, the first inner wall comprising a first wall portion extending in a first direction and a second wall portion extending in a second direction, and
• wherein both the first wall portion and the second wall portion are disposed between the part of the gear and the air sump.
