CO-OP 3 vs CO-OP E3

Verdict: CO-OP 3 vs CO-OP E3

The CO-OP 3 and the CO-OP E3 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 30 hp. CO-OP E3 is the lighter machine (1,642 kg vs 2,018 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. In short: choose the CO-OP 3 for outright pulling power, or the CO-OP E3 if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
