Caterpillar Forty vs Caterpillar Sixty

Verdict: Caterpillar Forty vs Caterpillar Sixty

The Caterpillar Forty and the Caterpillar Sixty are both tractors — here is how they stack up on the figures that matter. Caterpillar Forty leads on rated power with 49 hp against 40 hp. Caterpillar Forty is the lighter machine (6,180 kg vs 8,618 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Caterpillar Forty is the newer design (1934 vs 1925). In short: choose the Caterpillar Forty for outright pulling power, or the Caterpillar Sixty if a tighter budget and lighter footprint matter more.
