Oliver 1800 Series B/C vs Oliver 990

Verdict: Oliver 1800 Series B/C vs Oliver 990

The Oliver 1800 Series B/C and the Oliver 990 are both tractors — here is how they stack up on the figures that matter. Oliver 990 leads on rated power with 84 hp against 77 hp. Oliver 990 is the lighter machine (4,989 kg vs 9,205 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Oliver 1800 Series B/C is the newer design (1960 vs 1958).
