Experience seamless operation with the Swiftamatic 8 transmission. Featuring a shaft-driven gear type, it offers a practical 4 forward and reverse gears, coupled with a smooth friction cone clutch for precise engagement. The real magic lies in its dual-speed capabilities: a two-speed shift-on-the-move system that adjusts both transmission and PTO speeds on the fly, plus an additional two-speed range for the transmission that can be shifted when stopped. This flexibility means you can always find the perfect gear for any situation, from delicate maneuvering to powerful hauling.

Built for Comfort and Control

The Gravely 430 prioritizes operator comfort and control. Its open operator station provides a clear view of your surroundings, while the manual steering ensures responsive and intuitive handling. Stopping power is handled by reliable mechanical band brakes, offering dependable performance. The tractor rolls on lawn/turf tires, with 16-6.50x6 up front and larger 23-8.50x12 at the rear, providing excellent grip and minimizing ground impact. With a substantial 46-inch [116 cm] wheelbase and a length of 75.5 inches [191 cm], it offers a stable yet maneuverable platform.
