PTO Link® HD System Duo Bundle | Quick-Connect PTO for 35–130 HP Tractors & Category 1 or 2 Implements

The PTO Link®HD System is designed for all tractors rated from 35 HP to 130 HP (engine net) with Category 1 or 2 or pull-behind implements. PTO Link® is the original, universal PTO quick-connect system consisting of two interconnecting steel couplers. Its patented Open-Plate design replaces the traditional spline-to-driveline connection with a visible interface that’s both easy to see and reach. Now you can quickly and safely connect/disconnect implements at the tractor’s PTO in just seconds! This complete PTO Link® System includes both a Tractor (Female) Coupler and an Implement (Male) Coupler. For best results, every tractor should be equipped with a Tractor Coupler, and every implement should be equipped with an Implement Coupler.

What To Know About PTO Link

The Compact System fits Category 1 compact and subcompact tractors up to 70 HP with a rear 6-spline 540 RPM PTO — including Kubota BX, B & LX Series, John Deere 2520 (2005–2011), Yanmar SA Series, New Holland Workmaster 25S, Cub Cadet 6284D, Bad Boy 3026, LS MT122/MT125/MT225, Mahindra 1526/1626/2126, and Massey Ferguson 25, 1010, 1020, 1030 & 1035. The HD System covers tractors from 35 to 130 HP with Category 1 or 2 or pull-behind implements. Not sure which you need? Call 1-888-249-7412 with your tractor model.
No. The Compact and HD systems are not compatible with each other — couplers only pair within their own system. Pick the system that matches your tractor's horsepower and implement category, and stay with it across your implements.
Yes — every PTO Link system adds 5 inches to your driveline. Most implements have enough shaft travel to absorb it, but measure before you order if your setup is tight. And note: PTO Link is not an adapter, and to comply with ASABE standards it should never be combined with PTO adapters.
PTO Link® is a universal PTO quick-connect system made up of two couplers — a Tractor (Female) Coupler and an Implement (Male) Coupler — that let you attach and detach implements without wrestling the driveline by hand. There are two main options: the HD System Bundle, built for tractors rated 35–130 HP with Category 1 or 2 or pull-behind implements, ideal for rough conditions or high-torque, heavy-duty equipment; and the Compact Bundle, designed for smaller Category 1 tractors up to 70 HP paired with Category 1 implements only. Both bundles are available now on Agzaga.com.
For reliable PTO shaft extensions and couplers, look toward suppliers specializing in ag equipment parts, offering spline adapters, over-running clutches, and extension couplers built from durable steel for various tractor sizes. If you're after a quick-connect coupler rather than a traditional adapter, PTO Link on Agzaga.com offers a patented Open-Plate coupler system that replaces the traditional spline-to-driveline connection, letting you connect and disconnect implements at the PTO in seconds, with options covering compact tractors up to 130 HP models. Whichever route you choose, prioritize hardened steel construction and proper fit for your tractor's HP and spline configuration to ensure safe, long-lasting operation.
Choosing the right PTO adapter means matching splines, diameter, and power ratings between your tractor and implement: measure both shafts' spline count and diameter (e.g., 1-3/8" 6-spline vs. 1-1/8" 6-spline) and pick an adapter that converts one to the other, making sure its horsepower rating exceeds your tractor's PTO output—opting for heavy-duty, bolt-on designs over quick-attach pins for high-horsepower or heavy-load work. If you swap implements often, a product like PTO Link uses a patented quick-connect system that lets you attach an implement in seconds without tools, available for tractors up to 130 HP (though it's a connect system rather than a true adapter, so it shouldn't be combined with standard PTO adapters). For older tractors paired with modern rotary cutters, use an Over-Running Coupler to prevent implement inertia from pushing the tractor forward, and favor hardened steel construction and proper lubrication for durability. Let me know your tractor model and implement, and I can help pinpoint the exact size or system you need.
