Caterpillar D3 vs Komatsu D39EX-24
The Komatsu D39EX-24 is about 6% heavier than the Caterpillar D3 (9,930 vs 9,362 kg), which usually means more stability and lifting capacity but higher transport weight.
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.
