J.I. Case 401 vs J.I. Case 630

Verdict: J.I. Case 401 vs J.I. Case 630

The J.I. Case 401 and the J.I. Case 630 are both tractors — here is how they stack up on the figures that matter. J.I. Case 401 leads on rated power with 50 hp against 49 hp. J.I. Case 630 is the lighter machine (4,600 kg vs 5,850 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. J.I. Case 630 is the newer design (1960 vs 1955). In short: choose the J.I. Case 401 for outright pulling power, or the J.I. Case 630 if a tighter budget and lighter footprint matter more.
