Marathon 11x4.00-5 Flat-Free Lawn Mower Wheel with 3" Hub and 3/4" Oil-Infused Bushings — 11" Diameter, Non-Marking Polyurethane

The Marathon 01420P is a solid, flat-free 11x4.00-5 lawnmower tire mounted on a wheel with a 3" hub and 3/4" oil-infused bushings, engineered to deliver airless ride performance and dependable load capacity for zero-turn and garden tractors.

If you need a maintenance-light replacement wheel for a walk-behind mower, garden tractor or zero-turn, this Marathon assembly pairs a non-marking polyurethane foam tire with a stout stamped wheel and heavy-duty bushings. It mimics the shock-absorbing characteristics of pneumatic tires without the risk of flats, making it useful for commercial and homeowner equipment where downtime or frequent maintenance is a concern. The compact 11" overall diameter and 4" tread width suit smaller mowers and attachments that specify an 11x4.00-5 size.

Will this wheel fit my mower or attachment?

Compatibility depends on hub dimensions and mounting style. Confirm your existing wheel’s overall diameter, tread width and hub bore, and compare to the Marathon 01420P measurements.

• 11" tire diameter and 4" tread width to match 11x4.00-5 sizing
• 3" centered hub — verify hub location on your axle or spindle
• 3/4" oil-infused bushings — check axle diameter and bushing length
• Wheel fits many zero-turn mowers; always measure the existing tire sidewall and wheel bore

How does a flat-free polyurethane tire perform compared to air tires?

Solid polyurethane foam provides firm support and predictable handling without inflation. It won’t puncture or lose pressure, and it offers decent shock absorption for yard work, though ride quality can feel a bit firmer than a properly inflated pneumatic tire.

• Non-marking smooth tread protects turf and resists scuffing
• Solid construction eliminates flats and re-inflation needs
• Durable polyurethane resists ozone and many chemicals better than rubber
• Designed to simulate air-filled performance under typical mower loads

What are the load and maintenance considerations?

This wheel supports moderate loads and requires little routine maintenance. The Marathon 01420P is rated up to 300 lb and uses oil-infused bushings to reduce wear on axles and spindles.

• 300 lb load capacity — suitable for many residential and light-commercial mower applications
• 3/4" heavy-duty oil-infused bushings reduce friction and extend service life
• No tire pressure checks or patching needed; inspect bushings and mounting hardware periodically
• Not intended for highway or high-speed use — designed for lawn and turf equipment only

Who is this replacement wheel best for? Choose the Marathon 01420P if you want a low-maintenance, puncture-proof wheel for residential or light-commercial mowing where downtime is costly or frequent tire damage is a problem. It fits mowers and small turf machines that accept an 11x4.00-5 size with a 3" hub and 3/4" axle/bushing setup. If you prioritize a softer ride, conventional pneumatic tires remain an option, but for reliability, non-marking turf protection and straightforward installation, this Marathon flat-free wheel is a practical choice.
