Long 445 vs Long 510

Verdict: Long 445 vs Long 510

The Long 445 and the Long 510 are both tractors — here is how they stack up on the figures that matter. Long 510 leads on rated power with 49 hp against 42 hp. Long 445 is the lighter machine (3,850 kg vs 4,285 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Long 510 is the newer design (1979 vs 1972). In short: choose the Long 510 for outright pulling power, or the Long 445 if a tighter budget and lighter footprint matter more.
