Ford 3300 vs Ford 840
Verdict: Ford 3300 vs Ford 840
The Ford 3300 and the Ford 840 are both tractors — here is how they stack up on the figures that matter. Ford 840 leads on rated power with 40 hp against 39 hp. Ford 3300 is the lighter machine (1,428 kg vs 2,850 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Ford 3300 is the newer design (1965 vs 1957). In short: choose the Ford 840 for outright pulling power, or the Ford 3300 if a tighter budget and lighter footprint matter more.
