VEVOR PTO Shaft 1 3/8" PTO Drive Shaft, 6 Spline End Round End PTO Driveline Shaft, Series 4 Tractor PTO Shaft, 39"-55" Brush Hog PTO Shaft, Black PTO Shaft for Bush Hog/Finish Mower/Rotary Cutter Review

Overview

The VEVOR PTO Shaft (1 3/8", 6-spline, Series 4) is a heavy-duty driveline shaft designed for tractors and implements like brush hogs, finish mowers, and rotary cutters. It’s built for owners of compact or subcompact tractors (typically 20-50 HP) who need a reliable, adjustable replacement or spare PTO shaft without breaking the bank. With a 39- to 55-inch working length and a solid 4.7-star rating from over 1,000 reviews, this shaft aims to deliver Series 4 durability at a fraction of the OEM cost.

Who Should Buy This

• Tractor owners needing a budget-friendly replacement: If your original PTO shaft is bent, worn out, or missing, this VEVOR shaft offers a cost-effective fix for mowing, cutting, or light tillage applications.
• Hobby farmers and homesteaders: Running a 4- to 6-foot brush hog or rotary cutter on a 25-40 HP tractor? This shaft’s Series 4 rating and adjustable length make it a solid match for medium-duty chores like clearing overgrown pastures or maintaining trails.
• DIY mechanics and equipment flippers: If you repair or resell used implements, this shaft is an easy drop-in upgrade to replace rusty or mismatched drivelines, boosting resale value without overspending.
• Owners of older or orphaned implements: Need a universal shaft that fits standard 1 3/8-inch, 6-spline tractor PTOs? This one’s compatible with most Category 1 and 2 hitches, making it a versatile spare for oddball cutters or mowers.

Key Features Breakdown

• 1 3/8" x 6-Spline Ends: This is the standard North American PTO size for compact and utility tractors. The round end fits most brush hog gearboxes and mower decks, while the 6-spline profile ensures a snug, rattle-free connection. It’s not for European or metric splines, so double-check your implement’s input shaft.
• Series 4 Rating: Series 4 means a higher torque capacity than Series 1-3, typically handling up to 40-50 HP at 540 RPM. This matters if you’re running a heavier cutter or mowing thick brush—lower series shafts can twist or snap under load. VEVOR’s Series 4 is built with thicker tubing and stronger yokes for that extra margin.
• Adjustable Length (39" to 55"): The telescoping design lets you cut the shaft to fit your specific tractor-implement setup. Collapsed length is 39 inches; extended is 55 inches. You’ll need to measure from the tractor PTO to the implement input, then trim the plastic shield and tubing accordingly—don’t skip this step or you risk bottoming out.
• Black Powder-Coated Finish: The black coating isn’t just for looks—it resists rust and corrosion from grass, mud, and moisture. It’s not as tough as a galvanized finish, but for a $80 shaft, it’s a decent compromise. Expect some wear at friction points over time.
• Included Safety Shield: A plastic guard covers the rotating shaft, reducing the risk of clothing or debris getting tangled. It’s a basic shield—not as robust as metal ones on premium shafts—but it meets standard safety requirements. Keep it in place, especially if you’re mowing near fences or buildings.

Pros

1. Exceptional value for the price: At $80, this shaft costs half or a third of what you’d pay for a name-brand Series 4 driveline from Tractor Supply or OEM dealers, with similar build quality.
2. Easy to cut and install: The telescoping sections are clearly marked, and the plastic shield slides off for trimming. Most owners report a 20-minute install with a hacksaw and a drill for the retaining pin.
3. Solid torque handling for medium-duty use: It’s handled 4-foot brush hogs and 5-foot finish mowers on 30-40 HP tractors without excessive vibration or heat buildup, per user reviews.
4. Universal fit for common implements: Works with most standard round-end gearboxes on bush hogs, rotary cutters, and mowers—no adapter needed for 1 3/8-inch splines.
5. Decent rust resistance out of the box: The powder coating holds up well for the first season, especially if you store the implement indoors or under cover.
6. Good customer support from VEVOR: While not a pro for every brand, VEVOR’s USA-based support team has responded to sizing and warranty questions within 24-48 hours, per multiple reviews.

Cons

1. Plastic shield is flimsy: The included safety guard is thin and can crack if you hit a rock or stump. Some users replace it with a metal shield from Agri Supply for added durability.
2. Not ideal for heavy commercial use: If you’re running a 50+ HP tractor on a 7-foot rotary cutter daily, this shaft may heat up or wear out faster than a premium brand like Weasler or Bondioli & Pavesi.
3. Trimming instructions are basic: The manual lacks precise guidance on measuring and cutting. You’ll need to watch a YouTube video or measure twice to avoid cutting too short or too long.
4. Grease fittings are minimal: Only one zerk fitting on the cross bearing—some users wish for additional fittings on the telescoping tubes for easier lubrication in the field.

Bottom Line

The VEVOR PTO Shaft is a smart buy for tractor owners who need a functional, affordable driveline for light to medium-duty mowing and cutting. It’s not built for full-time commercial abuse or high-horsepower tractors, but for the price, it delivers reliable performance on compact tractors and standard implements. If you’re a hobby farmer, homesteader, or DIY mechanic looking to save $100+ over a brand-name shaft, this is a solid choice. Just budget for a metal shield upgrade if you work in rough terrain. For most users, it’s a 4.5-star value.

Frequently Asked Questions

Q: Will this PTO shaft fit my John Deere 1025R or Kubota BX series?
A: Yes, it fits most subcompact and compact tractors with a standard 1 3/8-inch, 6-spline PTO stub. Just measure the distance from your tractor’s PTO to the implement’s input shaft (with the implement attached) to ensure the 39- to 55-inch range works—most BX and 1-series tractors are within that range.

Q: Can I use this shaft on a 6-foot brush hog with a 45 HP tractor?
A: Yes, the Series 4 rating handles up to 50 HP at 540 RPM, so a 45 HP tractor is fine for
