Gravely 8199 vs Gravely Pro Master 18-H

Verdict: Gravely 8199 vs Gravely Pro Master 18-H

The Gravely 8199 and the Gravely Pro Master 18-H are both lawn tractors — here is how they stack up on the figures that matter. Gravely 8199 leads on rated power with 20 hp against 18 hp. Gravely 8199 is the lighter machine (424 kg vs 444 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Gravely Pro Master 18-H is the newer design (1989 vs 1980). In short: choose the Gravely 8199 for outright pulling power, or the Gravely Pro Master 18-H if a tighter budget and lighter footprint matter more.
