Caterpillar 308 CR vs Komatsu PC88MR-11
The Komatsu PC88MR-11 is about 8% heavier than the Caterpillar 308 CR (8,610 vs 7,946 kg), which usually means more stability and lifting capacity but higher transport weight.
Engine output is effectively the same on both machines.
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.
