Scag Flat Free Wheel Assemblies (Set of 2) 11x4.00-5 Compatible With Liberty, Freedom Z, SFZ36, SFZ48, SFZ52, SZL48, SZL52

What It Is

These are a set of two flat-free (airless) wheel assemblies sized 11x4.00-5, designed as direct replacements for the front caster wheels on Scag Liberty, Freedom Z, and SFZ/SZL zero-turn mowers. They eliminate flats and maintenance from punctures or dry rot.

Fitment & Compatibility

Before buying, confirm your mower model and deck size: fits Liberty Z (48”, 52”, 61”), Freedom Z (48”, 52”, 61”), SFZ36, SFZ48, SFZ52, SZL48, and SZL52. These are aftermarket assemblies, not OEM Scag parts. The wheel rim is 4.00 inches wide with a 5-inch diameter hub pattern. Verify your existing wheel’s bolt pattern (typically 3-bolt on these models) and axle hole size (usually 5/8” or 3/4”). Measure your old wheel’s overall diameter (11 inches) and width to ensure clearance under the deck. These are not compatible with Scag Turf Tiger, Cheetah, or V-Ride models.

Key Things to Know

• Quality concerns – Many users report premature bearing failure, wobbly wheels, or the flat-free material cracking within a season. The 2.7-star rating reflects these issues.
• Installation difficulty – Easy bolt-on swap using basic hand tools (wrench/socket for axle bolt). No tire mounting or inflation needed.
• Common gotcha – The flat-free material is hard and heavy, increasing steering effort on uneven ground. Not ideal for rough terrain or heavy commercial use.
• Weight difference – These weigh about 2–3 lbs more per wheel than pneumatic tires, which may slightly affect deck balance and cut quality on slopes.

Should You Buy It

Only if you need a quick, no-maintenance fix for a residential mower on flat, smooth lawns and are willing to risk lower durability for convenience. For commercial use or rough terrain, invest in OEM Scag pneumatic assemblies or a higher-rated aftermarket flat-free option.
