Kubota KX040-4 vs Yanmar ViO80-1
The Yanmar ViO80-1 is about 89% heavier than the Kubota KX040-4 (8,065 vs 4,265 kg), which usually means more stability and lifting capacity but higher transport weight.
The Yanmar ViO80-1 has about 30% more engine power (39 kW (52 hp) vs 30 kW (40 hp)).
Beyond the numbers, compare local dealer support, parts availability and resale value for Kubota and Yanmar in your region: over the life of a machine they often matter more than small specification differences.
