Verified model comparison
Compare two timber-extraction methods as parts of a harvesting system, not interchangeable carriers.
The 1910G forwarder carries timber on its bunk; the 620H skidder extracts stems using its grapple arrangement. Match the method to felling/processing, trail conditions and the landing plan. Payload and grapple opening are different concepts and cannot be ranked as the same capacity.
The Deere record uses a short wheelbase and specified tires without bogie traction tracks, although the artwork shows a loaded tracked-bogie arrangement. The Tigercat uses its standard wide tire offset and grapple. Confirm each actual tire, traction and attachment package before assessing access or transport.
Inspect forwarder crane/bunks and skidder arch/grapple alongside articulation, tires and driveline condition. Account for extraction distance, loading or bunching time and landing congestion. The comparison should include the complementary harvester, feller or loader the chosen method needs.
Generation/configuration-aware: measurement basis and reference configuration travel with each value. A difference in basis is not treated as a performance difference.

A high-capacity forwarder for carrying cut timber clear of the ground. The short-wheelbase and tire reference makes access and transport research more useful than a payload number alone.
