## Abstract

Mainframes for a self-propelled machine are disclosed. The mainframe includes first and second pockets that extend from the front end to the rear end of the mainframe. A hydraulic reservoir housing extends from the first side to the second side of the mainframe. The hydraulic reservoir housing is disposed between the front end of the mainframe and first and second drive openings.

## Claims

### Claim 1

A mainframe for a self-propelled machine, the mainframe having a front end a rear end and comprising:
a first side having a first bracket portion for supporting a load, the first bracket portion forming a first pocket that extends from the front end to the rear end of the mainframe, the first side defining a first drive opening for receiving a first hub of a drive mechanism;
a second side having a second bracket portion for supporting a load, the second bracket portion forming second pocket that extends from the front end to the rear end of the mainframe, the second side defining a second drive opening for receiving a second hub of a drive mechanism; and
a hydraulic reservoir housing that extends from the first side to the second side of the mainframe, the hydraulic reservoir housing being disposed between the front end of the mainframe and the first and second drive openings.

### Claim 2 (depends on 1)

The mainframe as set forth in claim 1 further comprising and engine bracket that extends from the first side toward the second side for mounting an engine to the mainframe, the engine bracket being disposed between the rear end and the first and second drive openings.

### Claim 3 (depends on 1)

The mainframe as set forth in claim 1 wherein the mainframe is a single weldment.
