Overview

The DEXSO 1 3/8" PTO Drive Shaft is a replacement driveline designed for compact to midsize tractors (typically 15-45 HP) paired with brush hogs, finish mowers, and rotary cutters. This Series 4 shaft features 6-spline ends with a round profile, adjustable from 43 to 61 inches, and is built for Category 1 three-point hitch implements. It’s best for tractor owners who need a durable, direct-fit replacement for worn or broken OEM shafts on bush hogs and mowers, especially those who prefer a no-nonsense, bolt-on solution over universal adapters.

Who Should Buy This

Tractor owners replacing a worn or broken PTO shaft on a 4-6 foot brush hog – If your existing shaft has bent tubes, stripped splines, or seized telescoping sections, this DEXSO shaft offers a direct replacement with minimal modification.
Small farm or hobby farm operators with Category 1 tractors (15-45 HP) – This shaft is built for standard compact utility tractors like Kubota B/L series, John Deere 1/2/3 series, Mahindra, or Yanmar.
Homeowners with finish mowers or rotary cutters needing a budget-friendly, reliable driveline – At $109.99, it undercuts many OEM replacements while still offering a shear bolt safety design and greaseable cross bearings.
DIY mechanics who want a shaft they can cut to length – The telescoping design allows you to trim the plastic shield and tube for a custom fit, ideal for non-standard implement hitch setups.

Key Features Breakdown

1 3/8" 6-Spline Ends (Round Profile) – This is the standard size for Category 1 PTO shafts on most compact tractors. The round end profile means it fits snugly into your tractor’s PTO stub and implement gearbox input without slop. If you have a quick-hitch or a PTO stub with a worn coupler, the round end reduces vibration better than some square-profile alternatives.

Adjustable Length: 43" to 61" – This covers the most common working lengths for 4-6 foot bush hogs and finish mowers. The collapsible range is critical: you need enough compression when raising the implement (shortest length) and enough extension when lowering (longest length). Measure your current shaft’s collapsed and extended lengths to confirm fit—this one works for most Category 1 implements with offset hitches.

Series 4 Rating – Series 4 denotes a medium-duty driveline, typically rated for 30-50 HP tractors at 540 RPM. This shaft can handle the torque of a 4-5 foot brush hog cutting heavy grass or light brush, but it’s not meant for 6-foot+ mowers on 60+ HP tractors. For a 5-foot bush hog on a 30 HP tractor, it’s a solid match.

Shear Bolt Safety – The implement end has a shear bolt (usually 1/4" or 5/16" Grade 2) that breaks if the blade hits a stump or rock, protecting your tractor’s PTO and gearbox. This is a must-have for brush hog use. Carry spare bolts—they’re cheap insurance.

Greaseable Cross Bearings – Both U-joints have grease zerks. This lets you lubricate the bearings every 8-10 hours of use, drastically extending shaft life. Many budget shafts omit these, so this is a genuine plus.

Plastic Safety Shield – The yellow plastic shield covers the rotating shaft. It’s functional but can crack if you’re rough with it. Replace it if it gets damaged—PTO shafts are dangerous.

Pros

Direct-fit for most Category 1 implements – The 1 3/8" 6-spline ends match standard tractor and gearbox splines without adapters.
Greaseable U-joints – You can actually lubricate the bearings, which is rare at this price point. This alone can double the shaft’s lifespan.
Shear bolt protection – A simple, effective safety feature that prevents catastrophic gearbox damage from impact loads.
Adjustable length range covers common mower sizes – The 43-61" range fits most 4-6 foot brush hogs and finish mowers with standard offset hitches.
Solid build for the price – The steel tube and weld quality are on par with OEM shafts costing twice as much.
Easy to cut to length – The telescoping inner tube and plastic shield can be trimmed with a hacksaw or angle grinder if your implement requires a custom fit.

Cons

Plastic shield is fragile – It’s adequate for light duty, but one snag on a branch or briar can crack it. Metal shields are more durable but cost more.
Not for high-horsepower tractors – This is a Series 4 shaft, maxing out around 45-50 HP. If you have a 60+ HP tractor and a 6-foot cutter, look for a Series 5 or 6 shaft.
No quick-disconnect coupler – You’ll need to slide the shaft onto the PTO stub manually. Some users prefer a push-button or twist-lock coupler for faster attachment.
Shear bolt location can be inconvenient – The bolt is at the implement end, which means you may need to crawl under the mower to replace it. A mid-shaft shear bolt is easier to access.

Bottom Line

The DEXSO 1 3/8" PTO Drive Shaft is a smart, budget-friendly replacement for compact tractor owners who need a reliable driveline for their 4-6 foot brush hog or finish mower. It delivers the essentials—greaseable U-joints, shear bolt safety, and a proper length range—without the premium price tag of OEM parts. It’s not built for heavy commercial abuse or high-horsepower tractors, but for a 15-45 HP tractor on a hobby farm or large property, it’s exactly what you need. If your old shaft is bent, stripped, or seized, this DEXSO is a straightforward upgrade. Just measure your collapsed and extended lengths first, and buy a pack of spare shear bolts while you’re at it.

Frequently Asked Questions

Q: Will this shaft fit my John Deere 1025R with a 4-foot bush hog?
A: Likely yes. The 1025R uses a Category 1, 1 3/8" 6-spline PTO. Measure your current shaft’s collapsed length (shaft fully compressed) and extended length (fully stretched). The DEXSO collapses to 43" and extends to 61", which covers most 4-foot cutters. If your current shaft is shorter than 43" collapsed, you may need to trim the inner tube.

How It Compares

Here is a head-to-head comparison of the two products you provided.

Important Note: These two products are not competitors. MOWER A (DEXSO) is a PTO drive shaft (a tractor attachment component), while MOWER B (Gorilla Carts) is a garden dump cart (a hauling wagon). They serve entirely different functions. The comparison below is structured as if the buyer is choosing between a tractor implement part and a yard utility cart, but the “buyer” is likely confused about which tool they actually need. The analysis will reflect this.

Quick Verdict

There is no winner because these products serve completely different purposes: MOWER A is a replacement driveline for a tractor-mounted rotary cutter, while MOWER B is a manual dump cart for hauling yard waste.

Side-by-Side Comparison

Feature	DEXSO PTO Drive Shaft	Gorilla Carts Dump Cart
Price	$109.99	$129.99
Power Source	Tractor PTO (requires tractor)	Manual / Human-powered (pull or tow)
Cutting Width	Not applicable (fits 43”–61” mowers)	Not applicable (4 cu ft tub)
Self-Propelled	No (it is a shaft, not a mower)	No (must be pulled by hand or ATV)
Best Yard Size	For tractors on 1–10+ acre properties	For small to medium yards (0.25–2 acres)
Warranty	Not specified (likely 1 year)	Limited lifetime (frame) / 1 year (parts)

Where DEXSO Wins

Essential for PTO-Driven Equipment – If you own a bush hog, finish mower, or rotary cutter (43”–61”), this DEXSO shaft is the critical power transfer component. Without it, the mower cannot function. The Gorilla Cart has zero relevance to mowing.
Heavy-Duty Construction – The 1 3/8” diameter, 6-spline round-end shaft is built for high-torque tractor applications. It can handle the stress of cutting thick brush and saplings, unlike a light-duty cart.
Universal Fit for Older Tractors – Series 4 PTO shafts are common on compact and utility tractors. This is a direct replacement for worn or broken drivelines, saving you from buying a whole new mower attachment.

Where Gorilla Carts Wins

Massive Popularity & Proven Reliability – With over 30,000 reviews and a 4.7-star rating, this cart is a bestseller. It is trusted by homeowners for hauling leaves, mulch, soil, and tools. The DEXSO has only 1 review.
Versatile, Not Single-Purpose – You can use the dump cart for gardening, landscaping, firewood, or even as a utility wagon. The DEXSO shaft is useless unless attached to a tractor mower.
Easy Dumping & Low Maintenance – The quick-release dumping mechanism and pneumatic tires make it simple to empty heavy loads without lifting. No tractor, fuel, or mechanical knowledge required.

Which Should You Buy?

Buy MOWER A (DEXSO) if:

You already own a tractor-mounted brush hog, finish mower, or rotary cutter (43”–61”) and the original PTO shaft is broken, bent, or missing.
You need a direct replacement for a Series 4, 1 3/8” 6-spline driveline and want a cost-effective part (under $110).
You are a farmer, rancher, or large-property owner who cuts heavy brush and needs a robust shaft that can handle high torque.

Buy MOWER B (Gorilla Carts) if:

You need to haul leaves, grass clippings, mulch, soil, or firewood around your yard or garden.
You want a simple, no-engine tool that you can pull by hand or behind a lawn tractor/ATV.
You value a proven, highly-rated product (30,000+ reviews) that is ready to use out of the box and requires no installation or mechanical skill.

Buy Neither if:

You are looking for an actual self-propelled lawn mower. The DEXSO is a part, not a mower, and the Gorilla Cart is a wagon. For a real mower, look at Honda, Toro, or EGO battery models.

Here is a head-to-head comparison of the DEXSO PTO Driveline Shaft and the WORX Cordless String Trimmer.

Important Note: These are not competing products. The DEXSO is a replacement driveline shaft for a tractor-mounted PTO (Power Take-Off) implement (like a brush hog or finish mower). The WORX is a standalone, handheld battery-powered string trimmer/edger. This comparison will focus on which product is the right type of tool for your specific mowing task.

Quick Verdict

The WORX wins for the vast majority of homeowners due to its standalone usability, massive user base, and low price, but the DEXSO is the only correct choice if you own a tractor and need to replace a broken PTO shaft on your rotary cutter.

Side-by-Side Comparison

Feature	DEXSO (PTO Shaft)	WORX (String Trimmer)
Price	$109.99	$89.99
Power Source	Tractor PTO (mechanical)	20V Cordless Battery (2 included)
Cutting Width	N/A (Shaft length: 43"-61")	12" (trimming) / 10" (edging)
Self-Propelled	No (passive shaft)	No (manual operation)
Best Yard Size	1+ acres (requires a tractor)	¼ acre or less (small lots)
Warranty	Not specified (1 review)	3-year limited warranty

Where DEXSO Wins

Tractor-Dependent Power: This is not a trimmer you hold. It is a replacement driveline for a tractor-mounted implement (bush hog, finish mower). If you have a tractor with a 6-spline, 1-3/8" PTO, this shaft delivers massive, continuous torque—enough to cut 4-foot tall brush, saplings, and heavy weeds that no handheld trimmer can touch. It wins on raw cutting capacity.
Durability for Heavy-Duty Work: The DEXSO is a Series 4 driveline shaft. Series 4 shafts are designed for medium-to-heavy-duty rotary cutters. They have stronger yokes and thicker tubing than light-duty shafts. If you are replacing a broken shaft on a 5-foot or 6-foot bush hog, this is a direct, heavy-duty replacement.
No Battery Anxiety: Because the DEXSO is powered by the tractor’s engine (via the PTO), it never runs out of charge. You can mow 10 acres of pasture in one session without stopping to swap batteries. The only limit is your tractor’s fuel tank.

Where WORX Wins

Standalone Usability: The WORX is a complete tool. Open the box, charge the batteries, and you are trimming edges, weedeating around fences, and cleaning up flower beds. The DEXSO is useless without a tractor and a compatible implement. For 99% of homeowners, the WORX is the only practical choice.
Massive User Confidence: The WORX has 27,806 reviews and a 4.4-star rating. The DEXSO has 1 review (5 stars). The WORX is a proven, mass-market product with known performance, known battery life, and known customer support. You are buying a well-established solution, not a gamble.
Versatility (Trimmer + Edger): The WORX features a quick-release button that lets you rotate the head 90 degrees to convert from a string trimmer to a dedicated lawn edger. It also has “Command Feed” which automatically advances the string when you bump the head. The DEXSO does one thing: spin a PTO shaft. The WORX handles two common yard tasks.

Which Should You Buy?

Buy the DEXSO (Mower A) if: You own a tractor (compact or sub-compact) and have a brush hog, finish mower, or rotary cutter with a broken driveline shaft. You need a direct replacement for a 1-3/8", 6-spline, round-end PTO shaft that extends from 43" to 61". This is a repair part, not a tool.

Buy the WORX (Mower B) if: You are a typical homeowner with a ¼-acre or smaller lot who needs to trim around trees, edge sidewalks, and clean up after mowing. You want a lightweight (5.5 lbs), cordless tool that is ready to use out of the box with two batteries included. This is the right choice for 99% of buyers.

Buy Neither if: You need a traditional walk-behind mower for cutting grass on a ½-acre lot. The DEXSO requires a tractor. The WORX is a trimmer, not a mower. You likely need a standard gas or battery push mower.
