Gravely GMT 900 vs Gravely Pro Master 30-H

Verdict: Gravely GMT 900 vs Gravely Pro Master 30-H

The Gravely GMT 900 and the Gravely Pro Master 30-H are both lawn tractors — here is how they stack up on the figures that matter. Gravely Pro Master 30-H leads on rated power with 30 hp against 26 hp. Gravely Pro Master 30-H is the lighter machine (635 kg vs 666 kg), which helps on soft ground and transport, while the heavier model carries more ballast for traction-limited draft work. Gravely Pro Master 30-H holds more fuel (40.1 L vs 26.5 L) for longer stints between fills. Gravely Pro Master 30-H is the newer design (1989 vs 1977). In short: choose the Gravely Pro Master 30-H for outright pulling power, or the Gravely GMT 900 if a tighter budget and lighter footprint matter more.
