Abstract
A modular machine including several removable components which are structurally interconnected in a manner to result in a rigid unit which is inexpensive to manufacture and easy to service or repair. The modular machine includes as its basic components a base frame assembly, an operator's control station, and a cab assembly. The base frame assembly comprises an open frame construction including opposed rectangular end members and opposed hollow rectangular side members. Ground-engaging wheels are mounted to the side members by using a unitized axle assembly including a hub and sprocket which extends into the interior of a side member. A fluid motor is mounted to the inner wall of each side member for driving the ground-engaging wheels connected to that side member. The operator's control station includes a front wall portion and rearwardly extending side wall portions. A generally U-shaped frame extends downwardly from the front and side wall portions for engagement within a complementary cavity formed by stepped inner walls on the side members of the base frame assembly. The cab assembly consists of an operator's seat attached to a box-like frame with the box-like frame being pivo…
