Gravely® Pro-Turn® zero-turn lawn mower lineup refined for productivity and operator comfort

Pro-Turn lineup gets upgraded

The new Gravely Pro-Turn 400, Pro-Turn 400X, Pro-Turn 600, and Pro-Turn MACH ONE commercial zero-turn lawn mowers replace the previous Pro-Turn 300, 500, 600, and MACH ONE models with a series of enhancements designed to bring more comfort, confidence, and efficiency to each workday. Highlights of these refinements include:
  • Redesigned cockpit positions operators lower in the machine, creating an improved center of gravity for a more planted feel across hills and uneven terrain.
  • Vertical-pin height-of-cut adjustment system.
  • Wider rollover protection structure (ROPS) contributes to a more commanding appearance. 
  • Suspension seat options tailor ride to different operators’ needs: Full suspension seat adjustable to operator weight is found throughout all Pro-Turn 400 and Pro-Turn MACH ONE models, air-ride seats on Pro-Turn 400X models, and the Pro-Turn 600 retains Gravely’s Operator Pod System that separates the operator from the chassis to offset shock and vibration. Each is designed minimize operator fatigue, helping operators stay fresh, more alert, and productive.

Familiar durability with greater assurance and value

Like their predecessors, these models continue Gravely's legacy of durability through: 
  • Fully-welded, tubular steel frames.
  • 7-gauge steel cutting decks with a reinforced leading edge.
  • Strong warranty coverage. The Pro-Turn 400 is backed by a 5-year / 1,250-hour limited warranty, while the Pro-Turn 400X, 600, and MACH ONE carry a 5-year / 1,500-hour limited warranty. All have limited lifetime warranties on the deck shell and frame. 
  • Smooth and reliable Hydro-Gear® ZT-5400 commercial transaxles boost ownership confidence with warranty coverage that matches the machine warranties. 
Best of all, these upgrades come without a price increase compared to predecessor models, further strengthening the long-term value of Gravely's flagship commercial zero-turns.

Proven performance features retained

With exception of the 60-inch MACH ONE, all models in the new lineup are available with 52-, 60, or 72-inch X-Factor® 3 decks for professional productivity and cut quality. A sloped leading edge gives grass more recovery time, Gravely’s Constant Belt Tension (CBT) system self-adjusts to produce consistent blade-tip speeds throughout the life of the belts, and snap-lock belt covers remove quickly without tools for easy cleaning. Baffling in the 60-inch decks has also been updated to enhance cut quality, particularly in northern grasses.

Commercial Kawasaki® FX engines remain at the top of the commercial lineup, ranging from the FX781EVO to the FX1000, with EFI options available on select models. Combined with Hydro-Gear ZT-5400 transaxles, the powertrain delivers ground speeds from 12 to 15 mph, and large 13.4-gallon fuel tanks means more time mowing and fewer fill-ups.

Protected, yet open engine compartments provide convenient access to maintenance points, including the oil drain, air filter and oil filter, simplifying service, minimizing downtime, and helping operators get back to work faster.

Updated Pro-Turn MACH ONE is the market’s answer for overgrowth  

For contractors regularly managing overgrown properties, the updated Pro-Turn MACH ONE continues to have unique capability in the commercial mowing market. Built on the Pro-Turn 400X platform, the MACH ONE’s industry-exclusive High-Volume-Output (HVO) tunnel deck processes and discharges large volumes of material rather than recirculating it, keeping operators moving quickly through tall, thick and challenging mowing conditions.
