Caterpillar 140 vs Komatsu GD655-7

The Caterpillar 140 is about 10% heavier than the Komatsu GD655-7 (18,500 vs 16,750 kg), which usually means more stability and lifting capacity but higher transport weight.

The Komatsu GD655-7 has about 3% more engine power (163 kW (219 hp) vs 158 kW (212 hp)).

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