Overview

The Brush Hog 43"-57" PTO Shaft is a heavy-duty replacement driveline designed for serious tractor owners who need to power mid-to-large rotary cutters, bush hogs, or other Category 1 implements. This Series 5 shaft bridges the gap between light-duty homeowner gear and commercial-grade equipment, offering a 43- to 57-inch working length range with 1-3/8" 6-spline connections on both ends. It’s built for tractors in the 25-60 HP range and is best suited for operators who push their equipment hard—think overgrown pastures, thick brush, and regular mowing of rough terrain.

Who Should Buy This

Tractor owners with 5+ acres of heavy brush – If you’re clearing blackberry thickets or saplings, this shaft’s Series 5 rating handles the torque without twisting like lighter-duty models.

Farmers and rural landowners who need a reliable backup – When your OEM shaft fails mid-season, this $117 replacement saves you from a trip to the dealer. It’s a solid spare to keep in the shed.

DIY mechanics on a budget – You know how to measure and cut a shaft to length. This unit saves you 40-60% compared to a dealer-branded equivalent, and the build quality holds up.

Operators of older tractors with standard 1-3/8" 6-spline outputs – Many vintage Ford, Kubota, and John Deere compacts use this spline pattern. This shaft fits without adapters.

Key Features Breakdown

43"-57" Working Length Range – The telescoping design adjusts from a compressed 43 inches to a fully extended 57 inches. That’s enough range for most 4- to 6-foot implements. Measure your PTO-to-implement distance carefully—this shaft requires a minimum of 6 inches of overlap when fully compressed to avoid binding.

1-3/8" 6-Spline Both Ends – This is the standard Category 1 tractor PTO output. No adapters needed for the vast majority of compact and utility tractors. The splines are cut cleanly with minimal slop, which reduces vibration at higher RPMs.

Series 5 Rating – This is the key spec. Series 5 shafts handle up to about 60 HP at 540 RPM. That’s enough for a 5-foot rotary cutter in heavy grass or a 6-foot finish mower. Don’t try this on a 100 HP tractor—you’ll twist it like a pretzel.

Black Paint Finish – It’s not just cosmetic. The paint is a basic rust-resistant coating that holds up better than bare metal. Expect it to chip where the telescoping sections slide, but that’s normal for any shaft in this price range.

Shear Bolt Protection – The driveline includes a shear bolt at the implement end. This is a safety feature: if you hit a stump or rock, the bolt snaps before the shaft or gearbox gets destroyed. Keep spares handy.

Pros

Exceptional value – At $117, you’re getting Series 5 performance for what most brands charge for Series 3 or 4. This is the best price-to-duty ratio I’ve seen for a 6-spline shaft.
Easy to cut to length – The telescoping sections are clearly marked, and the cross-and-bearing assembly uses standard lock rings. A hacksaw or angle grinder makes quick work of sizing.
Smooth telescoping action – The inner and outer tubes slide freely out of the box. No binding or galling, which means less wear on the driveline over time.
Universal fit with common implements – Works with most Bush Hog, Land Pride, Woods, and Howse cutters. The shear bolt hole pattern matches standard brush hog yokes.
Minimal vibration at 540 RPM – The splines are machined tighter than budget shafts. You won’t feel that annoying wobble in the seat.
Comes with hardware – Includes the shear bolt, lock rings, and cotter pins. You won’t need a second trip to the hardware store.

Cons

No quick-release collar – The implement end uses a standard pin-and-cotter retention. If you swap implements often, you’ll miss the push-button convenience of a premium shaft.
Black paint wears quickly at sliding points – The telescoping sections will show bare metal after a few hours of use. Apply grease and expect some surface rust unless you touch it up.
Not for heavy commercial use – The cross bearings are sealed but not serviceable. If you’re mowing 40 hours a week, this shaft will need replacement in 1-2 seasons.
Length range is tight for some setups – The 43-inch compressed length may be too long for very compact tractors or short implements. Measure twice before buying.

Bottom Line

The Brush Hog 43"-57" PTO Shaft is the smart buy for any tractor owner who needs a reliable, heavy-duty driveline without paying dealer prices. It’s not fancy—no quick-disconnect, no grease zerks on the bearings—but it gets the job done for pasture mowing, brush clearing, and general implement work on tractors up to 60 HP. The Series 5 rating gives you confidence in thick stuff, and the $117 price means you can keep a spare without guilt. If you’re running a 4- to 6-foot rotary cutter and your current shaft is worn, bent, or missing, buy this one. Just measure your PTO length carefully and keep a few extra shear bolts in the toolbox.

Frequently Asked Questions

Will this fit a 25 HP Kubota B series with a 5-foot bush hog?
Yes, as long as your tractor has a standard 1-3/8" 6-spline PTO output (most B-series do). Measure the distance from the PTO shaft end to the implement input when the mower is fully raised. The shaft must have at least 6 inches of overlap when compressed.

Can I shorten this shaft myself?
Absolutely. Remove the outer tube, mark your cut line (leaving 6 inches of overlap), and cut with a hacksaw or angle grinder. Deburr the edges and reassemble. It’s a 15-minute job.

Why does it come with a shear bolt instead of a slip clutch?
Shear bolts are simpler and cheaper, and they’re standard on most brush hogs under 6 feet. The trade-off is that you’ll snap bolts occasionally in heavy brush. Carry spares. If you need a slip clutch for shock protection, look for a Series 6 shaft instead.

How It Compares

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

Important Note: These two products are not comparable in function. Mower A is a tractor attachment (a PTO driveline shaft) used to connect a brush hog or rotary cutter to a tractor. Mower B is a push or tow-behind garden dump cart. One cuts grass; the other hauls debris. The comparison below treats them as intended—a tractor implement vs. a utility cart—and evaluates which is better for its specific job.

Quick Verdict

Mower A wins if you need a heavy-duty PTO shaft to connect a brush hog to a tractor for mowing; Mower B wins for every other yard task because it’s a highly rated, versatile dump cart with massive buyer confidence.

Side-by-Side Comparison

Feature	Mower A: PTO Driveline Shaft	Mower B: Gorilla Carts Dump Cart
Price	$116.96	$129.99
Primary Use	Tractor mowing (brush hog)	Hauling/dumping yard waste
Power Source	Tractor PTO (not self-powered)	Manual (pull/tow by hand or vehicle)
Cutting Width	43"–57" (for brush hog)	N/A (no cutting function)
Self-Propelled	No (tractor-driven)	No (manual or vehicle-towed)
Best Yard Size	2+ acres (needs tractor)	Any size (up to 1/2 acre typical)
Warranty	Not specified (likely limited)	Limited lifetime (Gorilla Carts typical)

Where Mower A (PTO Shaft) Wins

Enables Heavy-Duty Mowing: This Series 5 PTO shaft is built for serious brush hogging—thick grass, saplings, and overgrown fields. It’s the only option here that actually cuts vegetation. A 43–57 inch brush hog paired with this shaft can clear an acre in 30 minutes.
Tractor Compatibility: The 1-3/8” 6-spline ends fit most Category 1 compact and utility tractors (e.g., John Deere, Kubota, Ford). It’s a critical replacement part for anyone who already owns a tractor and brush hog.
Durability for Price: At $116.96, this is a cost-effective replacement for a driveline that would cost $200+ at a dealership. The Series 5 rating indicates it can handle moderate torque without bending or breaking.

Where Mower B (Gorilla Cart) Wins

Overwhelming Buyer Trust: 30,488 reviews with a 4.7-star average (vs. 16 reviews for Mower A). This is one of the most popular yard carts on the market, proven for reliability, ease of assembly, and dump function.
Practical Versatility: It hauls soil, mulch, leaves, firewood, tools, or even kids (with caution). The quick-release dump mechanism lets you tilt the 4-cubic-foot tub to unload heavy loads without lifting. Pneumatic tires roll smoothly over grass, gravel, and pavement.
No Tractor Required: You can pull it by hand, with a lawn tractor, ATV, or even a riding mower. It works for any yard size—from a small suburban lot to a large property—without needing a separate tractor investment.

Which Should You Buy?

Buy Mower A if…
You already own a compact tractor (15–35 HP) with a brush hog or rotary cutter that needs a replacement PTO shaft. You have 2+ acres of tough grass, weeds, or light brush to mow regularly. This is a pure functional part—not a toy or cart.

Buy Mower B if…
You need to move heavy, awkward loads around your yard—mulch, soil, rocks, branches, or garden tools. You don’t own a tractor, or you want a cart you can pull with a riding mower, ATV, or even by hand. The Gorilla Cart is the clear winner for 95% of homeowners because it solves the most common yard chore: hauling stuff.

Skip both if…
You need an actual self-propelled or push lawn mower for a typical suburban lawn (1/2 acre or less). Neither product cuts grass on its own. For that, look at a gas or electric walk-behind mower.

Here is a head-to-head comparison of these two very different lawn care tools.

Quick Verdict

There is no single “winner” because these are completely different tools for different jobs; Mower A (the Brush Hog PTO shaft) wins for heavy-duty tractor-mounted brush cutting, while Mower B (the WORX trimmer) wins for lightweight, electric trimming and edging around the home.

Side-by-Side Comparison

Feature	Mower A: Brush Hog PTO Shaft	Mower B: WORX Cordless Trimmer
Price	$116.96	$89.99
Power Source	Tractor PTO (mechanical, requires tractor)	Battery (20V, 2 included)
Cutting Width	43"–57" (adjustable)	12"
Self-Propelled	No (tractor provides propulsion)	No (manual push/carry)
Best Yard Size	5+ acres (heavy brush, fields)	0.25–1 acre (lawn edges, small yards)
Warranty	Not specified (typically 1 year from manufacturer)	3-year limited warranty

Where Brush Wins

Extreme Cutting Capacity: This is not a lawn mower in the traditional sense—it’s a heavy-duty brush hog driveline designed to power a rotary cutter through thick brush, saplings, tall grass, and weeds up to 2–3 inches thick. The 1-3/8", 6-spline PTO shaft transmits high torque from a tractor, making it suitable for clearing overgrown fields, pastures, or rough terrain that would destroy a standard push mower or string trimmer.
Massive Cutting Width: With an adjustable cutting width of 43 to 57 inches, this unit can clear a wide swath in a single pass. When attached to a tractor, you can mow large areas (5+ acres) in a fraction of the time it would take with a handheld trimmer. This is the correct tool for maintaining large rural properties, rights-of-way, or hobby farms.
Durability and Longevity: The PTO shaft is constructed from steel with a black finish, designed to withstand constant high-torque, high-impact use. It is a mechanical component with no batteries, motors, or electronics to fail. Properly greased, a Series 5 PTO shaft can last for decades, whereas battery-powered tools have a finite battery lifespan (typically 3–5 years).

Where WORX Wins

Ease of Use and Portability: The WORX trimmer weighs only 5.5 lbs and is cordless, so you can grab it and start trimming or edging immediately with no gas, oil, or heavy tractor. It’s ideal for quick touch-ups around flower beds, fences, sidewalks, and trees. The 20V batteries are lightweight and recharge in about 2–3 hours.
Versatility as a 2-in-1 Tool: This unit converts from a string trimmer to a wheeled edger with a simple push-button rotation of the head. The Command Feed system automatically advances the trimmer line, so you don’t have to bump the head. For homeowners who maintain a neat lawn, this is far more practical than a massive brush cutter.
Value and Mass-Market Confidence: At $89.99 with two batteries and a charger, the WORX offers excellent value for suburban lawn care. It has 27,806 ratings with a 4.4-star average, proving it’s a reliable, well-loved product for millions of users. The 3-year warranty also provides peace of mind that a PTO shaft (with no stated warranty) does not.

You own a tractor with a 1-3/8", 6-spline PTO and need to clear large areas of thick brush, saplings, or overgrown pasture.
You are maintaining a rural property of 5+ acres and need a heavy-duty, long-lasting mechanical cutting system.
You are replacing a broken PTO driveline on an existing brush hog and need a direct, affordable replacement part.

Buy Mower B (WORX Cordless Trimmer) if:

You are a suburban homeowner with a 0.25–1 acre lawn who needs a lightweight, easy-to-use tool for trimming grass and edging along sidewalks and driveways.
You want a battery-powered tool with no gas, no pull cords, and minimal maintenance—just charge and go.
You value a proven, highly-rated product with a 3-year warranty and millions of satisfied users for everyday yard cleanup.
