63740 Tailwheel Caster Fork Fits Bush Hog Rotary Cutter 4ft 5ft 6ft Decks, Compatible with Brush Hog, Land Pride, Woods, King Kutter, Rhino, Alamo, Tractor Rotary Cutters/Brush Mower Heavy Duty Steel Review

Overview

The Tailwheel 63740 Caster Fork isn’t a lawn mower itself—it’s a heavy-duty replacement part for the tailwheel assembly on rotary cutters and brush mowers. Designed to fit decks from 4 to 6 feet, it’s compatible with major brands like Bush Hog, Land Pride, Woods, King Kutter, Rhino, and Alamo. If your tractor’s brush mower has a broken or worn-out caster fork, this $57.99 steel component is built to get you back in the field without replacing the whole mower deck.

Who Should Buy This

Farmers and acreage owners with 4–6 foot rotary cutters who need a robust replacement when the original fork bends or cracks from heavy brush work. This isn’t for casual suburban mowing—it’s for folks clearing pastures, trails, or overgrown fields.

DIY tractor owners who prefer to repair rather than replace. If you’ve got a Bush Hog, Land Pride, or King Kutter cutter and the tailwheel assembly is wobbling or dragging, this fork is a budget-friendly fix that saves you from buying a whole new deck.

Operators of older or off-brand cutters who’ve struggled to find compatible parts. The universal fit for 4ft, 5ft, and 6ft decks means you can match it to a Rhino, Woods, or Alamo cutter without hunting through obscure part numbers.

Anyone who’s tired of flimsy aftermarket parts that bend on the first rocky pass. The heavy-duty steel construction here is built for real work, not light-duty lawn trimming.

Key Features Breakdown

Heavy-Duty Steel Construction – This fork is made from thick, welded steel, not stamped sheet metal. That means it can handle the constant side loads and impacts from rocks, stumps, and rough terrain. If you’ve snapped a cheap fork before, this one’s overbuilt to survive.

Fits 4ft, 5ft, and 6ft Decks – The universal sizing covers the most common rotary cutter widths. Whether you’re running a compact 4-footer on a sub-compact tractor or a 6-foot shredder behind a utility tractor, this fork fits the standard tailwheel mounting pattern.

Compatible with Major Brands – Bush Hog, Land Pride, Woods, King Kutter, Rhino, Alamo—these are the workhorses of the brush mower world. The 63740 is designed to match the bolt patterns and dimensions of OEM forks on these brands, so you’re not drilling new holes or fabricating adapters.

Includes Fork Only – This is the caster fork assembly itself, not the wheel or axle. You reuse your existing tailwheel or buy a separate wheel. That’s fine for most repairs, but keep in mind it’s not a complete tailwheel kit.

Direct Replacement Design – No modification needed on most models. Unbolt the old fork, bolt this one in place, and you’re back to mowing. The mounting holes line up with standard tailwheel brackets.

Pros

1. Durable steel build – Feels significantly heavier and sturdier than many OEM forks. It won’t twist or crack under normal brush hogging abuse.

2. Universal fit saves headaches – Works across multiple brands and deck sizes, so you don’t need to cross-reference a dozen part numbers.

3. Budget-friendly repair – At $58, it’s a fraction of the cost of a new tailwheel assembly or a replacement mower deck.

4. Easy installation – Bolts directly onto existing brackets with basic hand tools. No cutting, welding, or drilling required on most machines.

5. Strong customer satisfaction – A 4.8-star average from 7 reviews suggests real-world users are happy with the fit and durability.

6. Great for older equipment – If your cutter is 10+ years old and parts are getting scarce, this fork keeps it running without hunting for discontinued OEM parts.

Cons

1. Wheel not included – You’ll need to buy a tailwheel separately if yours is damaged. That adds $20–40 to the total cost.

2. Limited to 4–6 foot decks – Won’t work on larger 7-foot or 8-foot cutters, which have different spindle and bracket designs.

3. No bolt hardware included – You’ll need to reuse your existing bolts or buy new ones. The bolt size and thread pitch can vary by brand, so check before you install.

4. Only 7 reviews – While the rating is excellent, the sample size is small. Long-term durability data is limited compared to more established parts.

Bottom Line

The Tailwheel 63740 Caster Fork is a solid, no-nonsense replacement part for anyone with a 4- to 6-foot rotary cutter from a major brand. It’s built tougher than many OEM forks, installs without drama, and costs a fraction of what a dealer would charge. If your tailwheel fork is bent, cracked, or worn out, this is a smart buy—just remember to budget for a new wheel if yours is also shot. For farmers, landowners, and DIY tractor owners who keep their equipment running with their own tools, this fork earns a confident recommendation.

Frequently Asked Questions

Will this fit my older Bush Hog 305 cutter?

Yes, the 63740 is designed to fit Bush Hog models with 4–6 foot decks, including the 305 series. The mounting pattern matches the standard tailwheel bracket used on those cutters. Always double-check your existing fork’s bolt spacing, but most users report a direct bolt-on fit.

Do I need to replace the tailwheel at the same time?

Not necessarily. If your current wheel is in good shape (no cracks, bearings intact, tire holds air), you can reuse it with this fork. If the wheel is wobbling or damaged, it’s worth replacing—but the fork alone is the main structural weak point.

How do I know if this fork will match my bolt pattern?

Measure the distance between the two mounting holes on your current fork’s bracket. The 63740 uses a standard 3-inch center-to-center spacing, which matches most Bush Hog, Land Pride, Woods, and King Kutter cutters. If your spacing is different, you may need to drill new holes or find a specific brand fork.
