CO-OP 3 vs CO-OP E4

Verdict: CO-OP 3 vs CO-OP E4

The CO-OP 3 and the CO-OP E4 are both tractors — here is how they stack up on the figures that matter. CO-OP E4 leads on rated power with 43 hp against 37 hp. CO-OP 3 is the lighter machine (2,018 kg vs 2,406 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. CO-OP E4 is the newer design (1949 vs 1936). In short: choose the CO-OP E4 for outright pulling power, or the CO-OP 3 if a tighter budget and lighter footprint matter more.
