Oliver 500 vs Oliver Super 66

Verdict: Oliver 500 vs Oliver Super 66

The Oliver 500 and the Oliver Super 66 are both tractors — here is how they stack up on the figures that matter. Oliver 500 leads on rated power with 34 hp against 33 hp. Oliver Super 66 is the lighter machine (3,943 kg vs 4,094 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Oliver 500 is the newer design (1961 vs 1954). In short: choose the Oliver 500 for outright pulling power, or the Oliver Super 66 if a tighter budget and lighter footprint matter more.
