Solarhome Caster Fork 106-2196-01 107-9119-01 110-6581-01 Compatible with Toro 74419 74420 74425 74432 74433 74434 74437

What It Is

This is a replacement caster fork assembly for the front wheels of select Toro residential zero-turn mowers. It supports the front deck and allows the wheel to pivot freely during turns.

Fitment & Compatibility

Before buying, verify your mower model number—not just the brand. This fork fits Toro models 74419, 74420, 74425, 74432, 74433, 74434, and 74437. It replaces OEM numbers 106-2196-01, 107-9119-01, and 110-6581-01. Measure the original fork’s axle hole diameter (should be 1/2 inch) and the overall length (roughly 7 inches). Also check that your existing wheel and tire assembly (including bearings and spacers) will transfer over—this fork does not include the wheel or tire. Deck size isn’t a factor, but caster fork width must match your wheel’s hub width.

Key Things to Know

• Quality: Aftermarket part at a mid-range price. 4.7/5 rating from 4 reviews suggests good fit and durability for residential use.
• Installation difficulty: Moderate. You’ll need a socket set and possibly a hammer to remove the old fork’s pivot pin. No special tools required.
• Gotcha: The fork may not include a grease fitting—check if your OEM fork had one. If so, you may need to add grease periodically.
• Gotcha: Verify the pivot pin diameter matches your mower’s frame hole. Some Toro models use a 3/8-inch pin; others use 1/2-inch. Measure before ordering.

Should You Buy It

If your Toro ZT front caster fork is bent, worn, or broken and you have one of the listed models, this is a solid, cost-effective replacement. It’s not for heavy commercial use, but for residential mowing it offers good value and straightforward installation. Avoid if you need a complete wheel-and-fork assembly or if your mower uses a non-standard pivot pin size.
