Abstract

A frame assembly for a machine is disclosed. The frame assembly includes a main frame including a pair of spaced apart members extending longitudinally between the front and back of the machine and a front frame. The front frame includes a top plate having a first portion extending between the spaced apart members and a bottom plate coupled to the top plate. The bottom plate has a second portion extending between the spaced apart members. The front frame is connected to the main frame by attaching at least a portion of the first portion and at least a portion of the second portion to the spaced apart members.

First claim

What is claimed is:

1. A frame assembly for a machine, comprising:
a main frame including a pair of spaced apart members extending longitudinally between the front and back of the machine; and
a front frame comprising a top plate having a first portion extending between the spaced apart members, a bottom plate coupled to the top plate, the bottom plate having a second portion extending between the spaced apart members, the front frame being connected to the main frame by attaching at least a portion of the first portion and at least a portion of the second portion to the spaced apart members;
a first extension member extending downwards from the top plate and between the spaced apart members; the first extension member defining a first wall of a saddle for mounting an equalizer bar; and
a second extension member extending upwards from the bottom plate and between the spaced apart members; the second extension member defining a second wall of the saddle.

2. The frame assembly of claim 1 , wherein the first extension member and the second extension member are substantially parallel to each other.

3. The frame assembly of claim 1 , wherein each of the first extension member and the second extension member are connected to the spaced apart members.

4. A machine comprising:
a frame assembly comprising:
a main frame including a pair of spaced apart members extending longitudinally between the front and back of the machine; and
a front frame comprising a top plate having a first portion extending between the spaced apart members, a bottom plate coupled to the top plate, the bottom plate having a second portion extending between the spaced apart members, the front frame being connected to the main frame by attaching at least a portion of the first portion and at least a portion of the second portion to the spaced apart members; and

a power source supported by the front frame,
wherein the top plate is configured to extend beyond the bottom plate between the spaced apart members.

5. The machine of claim 4 , wherein the portion of the top plate extending beyond the bottom plate is connected to the spaced apart members.

6. A machine comprising:
a frame assembly comprising:
a main frame including a pair of spaced apart members extending longitudinally between the front and back of the machine; and
a front frame comprising a top plate having a first portion extending between the spaced apart members, a bottom plate coupled to the top plate, the bottom plate having a second portion extending between the spaced apart members, the front frame being connected to the main frame by attaching at least a portion of the first portion and at least a portion of the second portion to the spaced apart members; and

a power source supported by the front frame;
a first extension member extending downwards from the top plate and between the spaced apart members; the first extension member defining a first wall of a saddle for mounting a equalizer bar; and
a second extension member extending upwards from the bottom plate and between the spaced apart members; the second extension member defining a second wall of the saddle.

7. The machine of claim 6 , wherein the first extension member and the second extension member are substantially parallel to each other.

8. The machine of claim 6 , wherein each of the first extension member and the second extension member are connected to the spaced apart members.
