2 Pack 105-3471 Front Wheel & Tire Assembly 4.10x3.50-4 for Toro TimeCutter & Exmark Quest Zero-Turn Mowers, 3/4" Bearing ID, 4-1/4" Centered Hub, Pneumatic Tire with Grease Zerk, Replaces 105-3471

What It Is

This is a 2-pack of front wheel and tire assemblies designed for zero-turn mowers, specifically the Toro TimeCutter and Exmark Quest models. Each assembly includes a 4.10x3.50-4 pneumatic tire mounted on a 4-1/4" centered hub with a 3/4" bearing ID and a grease zerk for maintenance.

Fitment & Compatibility

Before buying, verify your mower’s model series and front wheel specifications. This set replaces OEM part 105-3471 and fits:

• Toro TimeCutter: Models SS4225, SS5000, SWX4250, SWX4800, SWX5000, MX4200, MX4250, MX5000, and Z4200/Z4800 (check your deck size under 50").
• Exmark Quest: Models QZT416, QZT522, QZT526, QZT606 (deck sizes 42" to 60").

Critical measurements to confirm:

• Bearing inner diameter: 3/4" (must match your axle spindle).
• Hub center: 4-1/4" (centered, not offset).
• Tire size: 4.10x3.50-4 (diameter ~10.5", width ~3.5").
• Wheel bolt pattern: Typically 4-bolt (check your existing wheel).

If your mower uses a different bearing ID (e.g., 5/8") or offset hub, this set will not fit. Measure your current wheel’s hub offset and axle diameter before ordering.

Key Things to Know

• Quality: The pneumatic tire offers a smooth ride and good traction, but the tube-type design means punctures can cause flats. The grease zerk helps extend bearing life, but you must grease regularly (every 25 hours or seasonally).
• Installation: Straightforward—remove the old wheel, slide on the new one, and secure with the existing nut. No special tools needed, but you may need a wrench for the axle nut.
• Common gotchas: The centered hub (vs. offset) is specific to these models; installing on a mower requiring offset wheels will cause alignment issues. Also, check that your axle spindle is 3/4" diameter; some older TimeCutter models use 5/8" spindles.
• Durability: Several reviews note the tire tread wears faster than OEM, especially on concrete. The bearings are sealed but benefit from greasing.

Should You Buy It

If you own a compatible Toro TimeCutter or Exmark Quest and need a direct replacement for a worn or damaged front wheel, this 2-pack is a cost-effective alternative to OEM parts. It’s best for DIY maintenance on residential zero-turn mowers with 3/4" axles and centered hubs. Avoid it if your mower uses offset wheels or a different bearing size.
