Abstract
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.
