Overview

The yzohu Aftermarket Heavy Duty Stump Jumper is a direct replacement part designed specifically for King Kutter rotary mowers, fitting 4-foot, 5-foot, and 6-foot models. This isn’t a standalone mower—it’s the critical blade pan assembly that protects your gearbox and driveline from stump strikes, rock impacts, and hidden debris. It’s built for owners of King Kutter finish and rough-cut mowers who need a rugged, weld-on replacement that won’t crack under heavy abuse, especially when clearing overgrown fields or reclaiming brushy land.

Who Should Buy This

King Kutter mower owners with worn or bent stump jumpers – If your original pan is cracked, warped, or has lost its edge after years of abuse, this is a direct swap that restores your mower’s protection without buying a whole new deck.
Small-acreage landowners (2-10 acres) – People who regularly mow pastures, ditches, or tree lines where hidden stumps and rocks are a constant threat. This part is for those who treat their mower like a tool, not a lawn ornament.
DIY mechanics and tractor hobbyists – If you’re comfortable with a wrench and a welder, this aftermarket part saves you hundreds over OEM replacements. It’s designed for hands-on owners who maintain their own equipment.
Budget-conscious operators – At $242.50, this is significantly cheaper than a genuine King Kutter stump jumper, making it a smart upgrade for anyone who wants heavy-duty protection without the dealer markup.

Key Features Breakdown

Compatibility with 4’, 5’, and 6’ King Kutter mowers – This one part covers the most common sizes, so you don’t have to measure splines or bolt patterns. It’s designed to bolt directly onto the gearbox output shaft and accept your existing blade hardware. The “403031-H” suffix indicates it’s an aftermarket equivalent to the OEM part.
Heavy-duty steel construction – The pan is stamped from thick-gauge steel, not thin sheet metal. This matters because a stump jumper takes the brunt of every impact—thin pans dent or crack after a few hits. This one is built to shrug off rocks and roots.
Weld-on or bolt-on design – While it bolts to the gearbox, the outer edge is intended to be welded to the mower deck’s blade spindle housing for maximum rigidity. This is a pro-level installation, but it results in a stronger connection than purely bolt-on designs.
Pre-drilled blade mounting holes – The pan comes with holes that match standard King Kutter blade patterns. You won’t need to drill or modify anything—just transfer your existing blades and hardware.
Corrosion-resistant finish – A black powder-coat or paint layer protects against rust from wet grass, mud, and storage. It’s not showroom quality, but it prevents the pan from rotting out after a few seasons.

Pros

Direct fit for King Kutter mowers – No guesswork, no grinding. Owners report it lines up perfectly with the gearbox spline and blade holes on 4’, 5’, and 6’ models.
Substantial steel thickness – At this price point, many aftermarket pans are flimsy. This one feels solid in hand, with enough meat to survive repeated stump strikes.
Cost-effective alternative to OEM – A genuine King Kutter stump jumper can run $350-400. This saves you roughly 30-40% while still delivering comparable durability.
Reinforced center hub – The area around the gearbox mount is beefed up to prevent cracking where stress is highest. This is a common failure point on cheaper pans.
Works with standard King Kutter blades – You don’t need special hardware or adapters. Just swap your existing blades onto this pan and go.
Easy installation for the mechanically inclined – If you can remove a nut and use a welder, you can install this in under an hour. No complex alignment required.

Cons

Requires welding for best results – The pan is designed to be welded to the deck, which means you’ll need a welder or a shop. Bolting it alone may not provide the same rigidity, and some users have reported vibration if not welded.
Not a genuine OEM part – While fitment is good, the finish isn’t as refined as King Kutter’s factory part. Some buyers note slight edge burrs that need filing, and the powder coat can chip if you’re rough with it during installation.
Limited installation instructions – The product comes with minimal paperwork. If you’re not familiar with mower driveline repair, you’ll need to look up a guide or video for your specific model.
No blade hardware included – You get the pan only. You’ll need to reuse your existing bolts, nuts, and blades, or buy them separately. This is common for aftermarket parts, but worth noting if you’re starting from scratch.

Bottom Line

If you own a King Kutter rotary mower and your original stump jumper is bent, cracked, or just plain worn out, the yzohu aftermarket pan is a no-brainer upgrade at $242.50. It’s not a perfect replica—you’ll need a welder and a bit of mechanical patience—but it delivers the same heavy-duty protection for a fraction of the OEM cost. I’d recommend this to anyone who uses their mower for rough work and wants to keep their gearbox alive without emptying their wallet. Just be prepared to spend an afternoon with a grinder and a welding mask. For the price, it’s hard to beat.

Frequently Asked Questions

Q: Will this fit my King Kutter 5-foot finish mower?
A: Yes, this pan is designed to fit 4-foot, 5-foot, and 6-foot King Kutter rotary mowers, including both finish and rough-cut models. The bolt pattern and spline size are consistent across these sizes. Check that your gearbox output shaft is the standard 1-1/8” diameter with a 6-spline pattern—most King Kutter mowers use this.

Q: Do I have to weld it, or can I just bolt it on?
A: You can bolt it on, but welding is strongly recommended. The pan is designed to be welded to the mower deck’s blade spindle housing for maximum strength. Bolting alone may lead to vibration or loosening over time, especially if you’re hitting stumps. If you don’t have a welder, a local fabrication shop can tack it on for a small fee.

Q: Does this come with blades or blade bolts?
A: No, the pan is sold without blades or hardware. You’ll need to reuse your existing King Kutter blades, bolts, and locknuts. If your old

How It Compares

Quick Verdict

There is no single winner here because these two products are completely different: the yzohu is a replacement blade assembly for tractor-mounted rotary mowers, while the Gorilla Carts is a tow-behind dump cart — so your choice depends entirely on whether you need to cut grass or haul heavy loads.

Side-by-Side Comparison

Feature	yzohu Stump Jumper (Mower A)	Gorilla Carts Dump Cart (Mower B)
Price	$242.50	$205.99
Product Type	Replacement blade/spindle assembly	Utility dump cart (towable)
Power Source	None (attaches to tractor PTO)	None (towed by lawn tractor/ATV)
Cutting Width	Fits 4’, 5’, 6’ rotary mowers	N/A
Self-Propelled	No (tractor-mounted)	No (towed)
Best Yard Size	1+ acres (used with tractor)	Any size with towing vehicle
Warranty	Not specified	Not specified

Where yzohu Wins

Heavy-duty stump-jumping capability – The yzohu is specifically designed as a heavy-duty stump jumper for rotary mowers used on rough terrain. If you mow fields with hidden stumps, rocks, or debris, this assembly protects your mower gearbox by deflecting impacts, reducing the risk of catastrophic damage.
Compatibility with multiple mower sizes – It fits 4-foot, 5-foot, and 6-foot King Kutter rotary mowers (and compatible models), making it a versatile replacement part for owners of these popular implements. At $242.50, it’s a direct aftermarket alternative to OEM parts at a lower price.
Proven performance for rough mowing – With a 4.6-star rating from 25 reviews, buyers report it handles heavy brush and occasional stump strikes without failing. This is a niche but critical advantage for anyone maintaining pasture, hay fields, or overgrown lots.

Where Gorilla Wins

Enormous versatility and practicality – The Gorilla Carts dump cart is a multi-purpose yard tool for hauling soil, mulch, firewood, rocks, tools, or garden waste. Its 6-cubic-foot tub and 1,200-pound haul capacity make it far more useful for landscaping and gardening than a mower blade assembly.
Exceptional value and proven reliability – At $205.99 with a 4.7-star rating from over 30,000 reviews, this cart is one of the highest-rated and most trusted yard tools on the market. The massive review count indicates consistent quality and real-world performance across countless use cases.
Quick-release dumping system – The cart features a hydraulic-style dump mechanism that lets you tilt the tub and empty heavy loads without manual lifting. Combined with pneumatic tires for smooth towing, it dramatically reduces physical strain during yard work.

Which Should You Buy?

Buy the yzohu Stump Jumper if: You own a 4-6 foot King Kutter or compatible rotary mower and regularly mow rough, stump-filled terrain where impacts are common. This is a specific replacement part for operators who need to protect expensive mower gearboxes from sudden strikes. It’s not for general homeowners — it’s for serious tractor owners.

Buy the Gorilla Carts Dump Cart if: You have a lawn tractor, ATV, or golf cart and need to move heavy or bulky materials around your property. Whether you’re spreading mulch, hauling firewood, clearing brush, or moving garden soil, this cart offers unmatched versatility, proven durability, and an unbeatable price-to-performance ratio.

Buy neither if: You need a standard walk-behind or riding mower for lawn cutting. The yzohu is a replacement part, not a complete mower, and the Gorilla Carts doesn’t cut grass at all. For typical suburban lawn care, look for a self-propelled or zero-turn mower instead.

Here is a head-to-head comparison of the yzohu Aftermarket Stump Jumper and the Sun Joe AJ801E Electric Dethatcher.

Important Note: These are fundamentally different machines. The yzohu is a heavy-duty replacement blade assembly for a tractor-mounted rotary cutter (brush hog). The Sun Joe is a handheld, corded electric dethatcher/scarifier for lawn care. They are not interchangeable, so this comparison focuses on which tool is correct for your specific job.

Quick Verdict

If you need to clear heavy brush, saplings, and rough terrain with a tractor, the yzohu wins for raw durability; if you are maintaining a standard lawn and removing thatch, the Sun Joe is the clear, practical winner for the vast majority of homeowners.

Side-by-Side Comparison

Feature	yzohu Stump Jumper (Mower A)	Sun Joe AJ801E Dethatcher (Mower B)
Price	$242.50	$149.99
Power Source	Tractor PTO (requires tractor)	Corded Electric (110V outlet)
Cutting Width	Fits 4’, 5’, 6’ (48–72 inches)	12.6 inches
Self-Propelled	No (tractor provides propulsion)	No (push-only)
Best Yard Size	Acres of rough pasture/brush	Small to medium lawns (< ½ acre)
Warranty	Not specified (aftermarket part)	2-year limited

Where yzohu Wins

Extreme Durability for Heavy Brush: The yzohu is a “Stump Jumper” blade carrier, designed to be bolted directly to a rotary cutter’s gearbox. It is made of heavy-duty steel to withstand impacts from rocks, stumps, and saplings up to 2-3 inches thick. It is a genuine “brush hog” component, not a lawn mower blade.
Massive Cutting Capacity: With a 4-to-6-foot cutting width, this attachment can clear an acre of overgrown field in minutes. It is intended for tractors with 20-50+ HP, making it the only choice for serious land clearing or maintaining large rural properties.
No Power Cord Limitations: It runs off the tractor’s PTO, so there is zero range restriction. You can clear a 10-acre field without ever stopping for a power cord or battery charge.

Where Sun Joe Wins

Far Lower Cost & Accessibility: At $149.99, the Sun Joe is cheaper than the yzohu alone. Even more importantly, it does not require a tractor. Any homeowner with a standard outdoor outlet can use it for basic lawn maintenance.
Precision Lawn Care (Dethatching/Scarifying): The Sun Joe is designed for lawn health. It removes thatch (dead grass layer) and moss, allowing water and nutrients to reach the soil. The yzohu would destroy a lawn—it is a brute-force cutting tool, not a grooming tool.
Overwhelming User Base & Proven Reliability: With 15,695 ratings and a 4.4-star average, the Sun Joe is one of the most popular lawn care tools on the market. It is a known quantity for homeowners. The yzohu has only 25 reviews, making it a niche, specialized part.

Which Should You Buy?

Buy yzohu (Mower A) if: You own a tractor with a 4’, 5’, or 6’ rotary cutter and need to replace a worn-out or broken stump jumper blade carrier. You are clearing heavy brush, small trees, or maintaining a large pasture, not a lawn. This is a repair/replacement part for a tractor implement.

Buy Sun Joe (Mower B) if: You are a homeowner with a standard lawn (under ½ acre) that has visible thatch, moss, or poor grass growth. You want an affordable, easy-to-use tool to revive your lawn in spring or fall. This is a lawn grooming tool, not a brush cutter.

Buy Neither if: You need a standard lawn mower for weekly grass cutting. The yzohu requires a tractor, and the Sun Joe only dethatches/scarifies—it does not cut grass to a uniform height. For regular mowing, buy a standard walk-behind or riding mower.
