CASE 850M vs Caterpillar D9

The Caterpillar D9 is about 392% heavier than the CASE 850M (49,997 vs 10,152 kg), which usually means more stability and lifting capacity but higher transport weight.

The Caterpillar D9 has about 264% more engine power (328 kW (440 hp) vs 90 kW (121 hp)).

Beyond the numbers, compare local dealer support, parts availability and resale value for Case and Caterpillar in your region: over the life of a machine they often matter more than small specification differences.
