An integral frame structure is provided to better absorb vibrations, stresses and/or high drawbar pull introduced in a machine by rear mounted attachments. The integral frame structure includes first and second spaced apart longitudinally extending beam members, a lower front cross beam portion connected to the first and second spaced apart longitudinally extending beam members and a rear beam portion connected to the first and second spaced apart longitudinally extending beam members adjacent the ends thereof. A rear mounted attachment mechanism is secured to the rear beam portion and adapted to attach a work implement. A portion of each of the lower front cross beam portion and the rear beam portion extends outwardly from each of the first and second spaced apart longitudinally extending beam members. An upper portion of the first and second spaced apart longitudinally extending beam members has a box shaped cross-section along its longitudinal length and the bottom portion thereof extends downwardly and outwardly to provide added vertical strength to the integral frame structure.

[ I claim:] [1.] An integral frame structure adapted for use on a machine having an engine, a transmission, a cooling system, associated cab and platform structure, and a rear mounted attachment mechanism operatively mounted thereon, the integral frame structure comprising:an elevated beam portion composed of first and second spaced apart longitudinally extending beam members each including formed plate members secured one to the other to form the respective longitudinally extending beam members;a lower front cross beam portion composed of formed plate members extending between and integrally secured to each of the longitudinally extending beam members;a rear beam portion having a rear attachment portion secured thereto and composed of vertically and horizontally oriented plate members secured one to the other to form the rear beam portion and integrally secured to each of the longitudinally extending beam members; anda bottom plate member secured to and extending transversely between the first and second longitudinally extending beam members and secured to and extending longitudinally between the bottom of the rear beam portion and the bottom of the front cross beam portion.
