Abstract
The present invention is directed toward a stabler leveling mechanism for tree harvesters. The present invention utilizes many of the same components of conventional leveling mechanisms for tree harvesters, but it alters the pivot axis of a swing-house assembly. A conventional swing-house assembly pivots about an axis parallel to the top surface of a carriage on level ground. That conventional assembly can be deleterious, therefore, applicant has altered the pivot axis of the swing-house assembly. Admittedly, merely moving the pivot axis seems simple but it is difficult. The components had to be constructed differently to obtain the desired results and simultaneously make the device stable within the working environment.
