J.I. Case SI vs J.I. Case W-4

Verdict: J.I. Case SI vs J.I. Case W-4

The J.I. Case SI and the J.I. Case W-4 are both industrial tractors — here is how they stack up on the figures that matter. J.I. Case W-4 leads on rated power with 40 hp against 35 hp. J.I. Case SI is the lighter machine (1,984 kg vs 4,310 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. J.I. Case W-4 is the newer design (1978 vs 1942). In short: choose the J.I. Case W-4 for outright pulling power, or the J.I. Case SI if a tighter budget and lighter footprint matter more.
