CO-OP 3 vs CO-OP E5

Verdict: CO-OP 3 vs CO-OP E5

The CO-OP 3 and the CO-OP E5 are both tractors — here is how they stack up on the figures that matter. CO-OP E5 leads on rated power with 39 hp against 37 hp. CO-OP 3 is the lighter machine (2,018 kg vs 6,041 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 79.5 L) for longer stints between fills. In short: choose the CO-OP E5 for outright pulling power, or the CO-OP 3 if a tighter budget and lighter footprint matter more. Compare the full spec tables below before booking a demo.
