John Deere 850L vs Komatsu D51EX-24

The John Deere 850L is about 60% heavier than the Komatsu D51EX-24 (20,750 vs 13,000 kg), which usually means more stability and lifting capacity but higher transport weight.

The John Deere 850L has about 73% more engine power (168 kW (225 hp) vs 97 kW (130 hp)).

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