Develon DX300LC-7 vs Komatsu PC290LC-11
The Develon DX300LC-7 is about 5% heavier than the Komatsu PC290LC-11 (31,800 vs 30,330 kg), which usually means more stability and lifting capacity but higher transport weight.
The Develon DX300LC-7 has about 37% more engine power (202 kW (271 hp) vs 147 kW (197 hp)).
Beyond the numbers, compare local dealer support, parts availability and resale value for Develon and Komatsu in your region: over the life of a machine they often matter more than small specification differences.
