Caterpillar 301.7 CR vs Kubota U17-3
The Caterpillar 301.7 CR is about 11% heavier than the Kubota U17-3 (1,852 vs 1,675 kg), which usually means more stability and lifting capacity but higher transport weight.
The Caterpillar 301.7 CR has about 33% more engine power (16 kW (21 hp) vs 12 kW (16 hp)).
Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and Kubota in your region: over the life of a machine they often matter more than small specification differences.
