The Agrimax Triangular Profile Tube Multi-Size Universal Joint PTO Drive Shaft is a cost-effective, stable power take-off transmission component built for general agricultural tractors and PTO-driven implements. It transfers rotary power from the tractor PTO output to farm implements. The assembly features a triangular telescoping tube, cross-type universal joints on both ends, safety protective guards and retaining chains.
This series covers multiple models and cross sizes. Buyers can select the proper configuration according to required horsepower, torque, closed length and connection dimensions. Compatibility with tractor brands, implement models and OEM equivalence needs to be verified against your equipment and connection requirements before ordering. Custom cut-to-length service is available.
The central telescoping tube adopts a triangular profile, different from star, lemon and hexagonal tubing. The table below lists inner and outer tube dimensions and corresponding codes for tube pairing.
Compared with round tubes, the triangular profile provides stable multi-point contact between sliding inner and outer tubes, evenly distributing transmitted torque and resisting regular farm shock loads. Compared with star profile tubes, triangular tubing delivers balanced performance at a competitive cost; compared with lemon profile tubes, it prioritizes steady torque transmission for routine farm work instead of quiet high-frequency telescoping.
Triangular tube: Core telescoping section with triangular profile, matched by inner and outer tube codes. Universal joints: Heavy-duty cross-type universal joint assemblies fitted on both ends to accommodate angular offset between tractor and implement. Exact joint series and bearing material to be confirmed upon inquiry. Protective guards: Guard housings cover rotating tube and joint zones for operator safety. Exact guard material and relevant standards to be confirmed. Retaining chains: Attached to guards to restrain the guard during operation; chain specification available on request. Material: Tube, yoke and cross are constructed from carbon steel for agricultural transmission service. Optional heat treatment is available to improve wear resistance. Exact material grade can be confirmed during quotation. Surface finish: Uniform yellow-gold coating for corrosion protection; product and warning labels are fitted on the shaft body. Drawings & Photos: Technical drawings mark Closed Overall Length (Lmin) and Closed Cross-to-Cross length (C-C). Model-specific Lmin and C-C values are not preset in the specification table, as the closed length is custom-cut according to your equipment requirement. Dimension units are assumed to be millimeters; please verify before final use.

Stop the engine, disengage the PTO and lock out and tag out to prevent unexpected startup before any installation, inspection or maintenance. Confirm the model, D × L cross size, triangular tube code, spline specification, closed overall length Lmin and cross-to-cross C–C dimension to ensure proper fit. Make sure both ends are fully engaged and locking components are secured. Keep protective guards and retaining chains correctly installed and fastened before operation.Never alter or remove the protective guard. Guards are not optional accessories.This guard is designed for operator protection. Do not operate without the guard fully assembled and secured. Inspect universal joints, guards, chains and connecting parts before each use. Do not operate the shaft with damaged or missing safety guards. Follow regular lubrication and maintenance schedules for universal joints to extend service life. Stop operation and inspect the shaft if abnormal vibration, noise or visible damage occurs.
Packing: Standard export carton or woven bag. Each shaft is individually packed to avoid transit damage. Minimum order quantity is negotiable.
To get an accurate quotation, please provide the following information: ✅ Required: model, D × L cross size, spline specification, working horsepower & torque requirement, Lmin / C-C dimension ⭕ Optional: application type, target market, order quantity, drawing or photos of your existing shaft We will verify the suitable configuration and confirm tube code, material and finish for you.
A: Triangular profile tubes deliver stable torque transmission with balanced cost performance for general farm work. Star profile tubes are built for heavy-duty scenarios with excellent anti-slip performance under frequent torque impact. Lemon profile tubes have smooth curved transition surfaces, run quieter and perform well for high-frequency telescoping work under normal operating load. Hexagonal tubes offer balanced performance with cost advantages for standard farm tasks.
A: Lmin is the overall closed length of the whole shaft assembly; C–C is the distance between the centers of the two crosses when the shaft is fully retracted. Supply both values for precise matching. These data are not included in the specification table and need separate confirmation.
A: Yes. Custom spline specifications are available upon request. We also offer a full range of standard ASAE spline options.
A: It fits most common PTO-driven implements including rotary cutters, mowers and balers. Interface, spline and load must be matched before purchase.
