CO-OP 3 vs CO-OP B1

Verdict: CO-OP 3 vs CO-OP B1

The CO-OP 3 and the CO-OP B1 are both tractors — here is how they stack up on the figures that matter. CO-OP 3 leads on rated power with 37 hp against 18 hp. CO-OP B1 is the lighter machine (954 kg vs 2,018 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. CO-OP 3 holds more fuel (106.0 L vs 45.4 L) for longer stints between fills. CO-OP B1 is the newer design (1941 vs 1936). In short: choose the CO-OP 3 for outright pulling power, or the CO-OP B1 if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
