3 Point Linkage Parts — Manufacturer & Exporter to the USA
What Are 3 Point Linkage Parts?
A tractor’s 3-point linkage system is the backbone of modern farming. It connects the tractor to implements like plows, harrows, mowers, tillers, and seeders — transferring power, controlling depth, and keeping equipment stable during operation. Without a reliable linkage system, even the most powerful tractor cannot do its job.
At Jrs Farm Parts, we manufacture a complete range of 3 point linkage parts engineered for durability, precision, and long service life. As an ISO-certified manufacturer based in Ludhiana, India, we export our linkage components directly to dealers, distributors, and equipment suppliers across the United States and 64+ countries worldwide.
Understanding Category 1, 2, and 3 Linkages
Before selecting linkage parts, it is important to understand the three standard hitch categories. These categories are defined by the diameter of the upper link pin and determine which tractors and implements the parts are compatible with.
| Category | Top Link Pin Diameter | Tractor HP Range | Typical Applications |
|---|---|---|---|
| Category 1 | 19 mm (3/4″) | Up to 45 HP | Compact and sub-compact tractors, lawn and garden equipment, small implements |
| Category 2 | 25.4 mm (1″) | 40–100 HP | Utility tractors, mid-size farm equipment, most general-agriculture implements |
| Category 3 | 31.75 mm (1-1/4″) | 80–225 HP | Row-crop and large-frame tractors, heavy tillage equipment, large mowers |
Jrs Farm Parts manufactures linkage components for all three categories. Our parts are interchangeable with major tractor brands and meet or exceed OEM specifications for fit and performance.
Our 3 Point Linkage Parts Range
Top Link Assemblies
The top link — also called the center link or upper link — is the adjustable arm that connects the top of the implement to the tractor. It controls the implement’s angle of attack and is essential for proper depth control and level operation.
We manufacture top link assemblies in multiple configurations:
- Heavy-duty telescopic top links with forged Cat 1, 2, or 3 ends
- UNC-thread top links for the North American market
- Metric-thread top links (M22, M24, M27, M30) with rolled threads for strength
- Ratchet-jack top links for quick, tool-free adjustment
- Rapid-hook top links for fast implement changes
- OEM-replacement top links compatible with John Deere, Massey Ferguson, New Holland, Case IH, and other major brands
All top link assemblies feature forged ball ends, heavy-wall center tubes, and precision-machined threads for smooth adjustment under load.
Lower Link Arms & Components
The lower link arms carry the primary weight of the implement and connect to the tractor via lift arms. Key components we supply include:
- Lower link balls — hardened ball inserts (58-62 HRC) that fit into lower link arm sockets, available in multiple bore diameters
- Lower link pins — category-specific pins that attach lift arms to the lower links
- Weld-on ball ends — forged ends with hardened ball inserts for custom implement fabrication
Pins & Retaining Hardware
Every 3-point connection relies on pins to stay secure. Our pin range covers every connection point in the linkage system:
- Top link pins — category-specific diameters with or without heads
- Hitch pins — bent handle, fixed handle, and temple handle styles in multiple diameters
- Linch pins — standard, spring-loaded, butterfly, and forged variants for quick retention
- Clevis pins — utility and screw-pin types for implement connections
- Lynch pins for tubes and pipes — specialty configurations for OEM applications
- Implement pins — single and double mounting styles across categories
- R-pins and hair-pin clips — secondary retention for critical connections
Stabilizers & Sway Control
Stabilizers prevent the implement from swinging side-to-side during transport and operation. Without proper stabilizers, implements can contact tractor tires or create uneven working depth. Our stabilizer range includes:
- Chain stabilizer assemblies — turnbuckle-adjusted chains with forged ends, available for Category 1 and 2 tractors
- Ratchet-jack stabilizers — mechanical ratchet adjustment for quick tensioning
- Standard stabilizer assemblies — rigid bar-type with forged rectangular or round head ends
- Stabilizer ends — individual replacement ends for field repairs
Leveling Assemblies
The leveling assembly — also called the adjustable levelling arm or lift arm leveling box — sits on the right-side lower link and allows the operator to adjust implement tilt. This is critical for plowing, grading, and any operation where the implement must sit level relative to the ground.
We manufacture leveling assemblies in multiple configurations:
- Heavy-duty with gearbox for smooth adjustment under load
- Standard without gearbox for lighter applications
- Brand-specific replacements for John Deere, Massey Ferguson, Ursus, and others
- Right-hand (adjustable) and left-hand (fixed) configurations
Balls & Ball Ends
Precision-ground balls and ball ends ensure smooth articulation at every pivot point in the linkage:
- Top link balls — replacement balls for top link ends
- Lower link balls — hardened inserts for lower link arm eyes
- Ball double bore — dual-diameter balls for multi-category compatibility
- Hitch balls — for trailer couplers and drawbar applications
- Guide cone balls — self-aligning designs for faster implement hookup
Drawbars
The drawbar provides a rear attachment point for trailed implements. Our swing drawbars are available in multiple cross-section profiles (from 63×25 mm to 80×40 mm) to match tractor horsepower requirements. Each drawbar is forged from high-grade steel and designed for the pulling forces encountered in heavy field work.
Weld-On Ends & Custom Fabrication Components
For equipment builders and those fabricating custom implements, we supply forged weld-on ends in multiple configurations: with base plates, with centering pin guides, with slotted mounting, and with ball inserts pre-installed. These allow fabricators to build implements that connect directly to standard 3-point linkage systems.
