OTR® NDX™ Grass Master Air-Less Lawn / Turf Tire

The OTR® NDX Air-Less Grass Master Turf and Utility Tire is a high traction all-purpose Zero Turn (ZTR) tire and a great OEM replacement! 

Keep your lawn, turf, and utility equipment up and running — even under the worst conditions — with the OTR NDX™ Air-Less Grass Master tire + wheel system. This isn’t your typical “stay-flat” tire. This is a patented run-flat solution, built to deliver unmatched reliability for commercial zero-turn mowers, utility mowers, and turf utility vehicles used in applications where downtime is not acceptable. Because the Grass Master NDX is sold as a complete assembly (tire + wheel), installation is simple, and you can bolt it on just like your OEM components. Please check bolt pattern and fitment details before ordering.

Designed with heavy use in mind, the NDX system lasts up to twice as long as other airless competitors — even under heavy loads and after sustaining serious damage. Thanks to its solid construction, this tire helps reduce downtime and repair costs, making it a smart investment for pro landscapers and fleet operators. What’s more: because it’s a run-flat design, you won’t have to worry about flats slowing you down.

• Commercial zero-turn mowers
• Stand-on and riding turf mowers
