Caltric Front Caster Wheel Compatible with Toro 74620 74621 74622 74623 SS3200 SS4200 74624 SS4235

What It Is

This Caltric front caster wheel replaces the OEM front wheel on select Toro TimeCutter and SS series zero-turn mowers. Designed to handle the weight and steering demands of commercial-grade mowing, it’s a direct-fit aftermarket alternative for worn or damaged original wheels.

Fitment & Compatibility

Check your mower model and deck size. This wheel fits Toro models 74620, 74621, 74622, 74623, 74624, SS3200, SS4200, and SS4235. It is not universal—verify your mower uses a 3/4-inch axle and a 10-inch wheel diameter. Measure the existing wheel’s bolt pattern (typically 4 on 4 inches) and tire width (usually 4 inches). Caltric parts are aftermarket; confirm OEM part numbers (e.g., Toro 121-2840) match your mower’s parts diagram. Avoid buying if your mower has a different axle size or wheel offset.

Key Things to Know

• Quality vs. OEM: Caltric wheels are generally comparable to OEM but use slightly softer rubber. They work fine for residential or light commercial use but may wear faster under heavy daily use or on abrasive surfaces.
• Installation difficulty: Easy—remove the old wheel, slide on the new one, and secure with the existing cotter pin or lock nut. No special tools needed. Check that the bearing spins freely before mounting.
• Common gotchas: The supplied hardware may not match your mower’s axle nut or washer size. Keep your original hardware if possible. Also, verify that the caster swivel isn’t binding after installation—apply grease to the pivot if needed.
• Weight capacity: This wheel is rated for up to 300 lbs per wheel, sufficient for most zero-turn mowers. Do not exceed that load (e.g., adding heavy attachments to the front).

Should You Buy It

If you need a budget-friendly, drop-in replacement for a worn front caster on one of the listed Toro models, this Caltric wheel is a solid choice for residential or light commercial use. It’s not built for extreme abuse or heavy daily commercial duty—if you run a landscaping business, consider OEM or a heavy-duty aftermarket option. For the price, it offers good value and an easy fix.
