Komatsu PC55MR-5 vs Kubota KX057-5

The Kubota KX057-5 is about 6% heavier than the Komatsu PC55MR-5 (5,534 vs 5,210 kg), which usually means more stability and lifting capacity but higher transport weight.

The Kubota KX057-5 has about 29% more engine power (36 kW (48 hp) vs 28 kW (38 hp)).

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