Overview
Product Description
T4 uses the same 27 mm pin diameter as T3 but with a longer journal (74.6 mm vs 70 mm), raising peak torque to 780 Nm. T4 is the preferred choice where T3 is borderline — particularly for implements with significant inertia at start-up such as disc harrows, forage wagons, and centrifugal spreaders. For the full T Series PTO drive shaft range, see our category page.
T4 occupies the boundary between light and medium-duty agricultural PTO applications. In the Argentine market, T4 is the standard specification for replacement shafts on 25–40 hp tractors used in soybean and sunflower production, where operators run implements continuously during planting and harvest windows. The sealed cross-kit specification has been validated across two full seasons in Argentine field conditions without cross-kit failure at the standard 8-hour regrease interval.
T4 is the highest series where the shaft weight remains manageable for a single operator to attach and detach without mechanical assistance. Above T4, increasing cross-kit and tube dimensions make solo handling progressively more difficult. Implements with flywheel masses — drum mowers, forage conditioners, centrifugal spreaders — regularly generate start-up torque spikes at the T3–T4 boundary. Specifying T4 in these applications eliminates cross-kit failure risk on the first cold-start of the day. Full CE, ISO 9001, and TS/16949 documentation for Brazil INMETRO and LGPD compliance.

Key Features
Alloy Steel Construction Throughout
Yokes, tubes, and cross-kit cups all in alloy steel. No cast-iron components. Material certificates available per production lot.
Long-Life Lubrication System
EP2 lithium complex grease at factory fill. Re-grease nipple at each cross kit. IP67 seals rated for high-pressure wash-down.
Integrated Safety Shield System
Full-length HDPE bellows encloses all rotating components. Double-ended chain anchor system prevents shield rotation. CE compliant.
Standard and Wide-Angle Yoke Options
Standard cardan joint yoke plus wide-angle option for implements requiring articulation beyond 25 degrees at the hitch point.
MOQ-Friendly Stock and Custom
Single-piece orders on all stock series. OEM custom from 50 pieces. No tooling charge for standard length variations.
Complete Import Documentation
CE declaration, ISO certs, dimensional drawings, batch reports. Covers Brazil INMETRO, Argentine SENASA, and EU CE requirements.
Typical Applications
Rotary Mowers
25–40 hp mid-size rotary cutter drive. T4 provides peak torque margin over T3 for 1.5–1.8 m working width implements.
Rotavators
Deep tillage up to 200 mm working depth. High torque at low rpm sustained over multiple passes. T4 cross-kit handles this continuous load profile.
Centrifugal Pump Drive
Continuous 540 rpm pump operation for centrifugal and piston irrigation pumps in the 25–40 hp tractor class.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Match Series to Application
From the torque table, confirm the rated Nm at your operating RPM comfortably exceeds implement load. Add 20% safety factor.
Set Compressed and Extended Length
Raise and lower implement through full range. Inner tube must engage outer by 50 mm min at extension, 80 mm min at compression.
Connect Yoke to PTO Stub
Push splined yoke over PTO stub until push-pin snaps into groove. Withdraw slightly to confirm. Install implement-end yoke the same way.
Fix Safety Shield Chains
Fasten tractor-end chain to a rigid tractor component. Fasten implement-end chain to implement frame. Verify taut with implement level.
Grease Cross Kits Before Use
Apply 2–3 pumps EP2 per nipple. Reapply every 8 hours normal conditions. Wipe excess from shield exterior after greasing.
Frequently Asked Questions
- —T Series uses a triangular (trilobular) inner and outer tube profile
- —This profile transmits torque efficiently while allowing the tube to telescope for length adjustment
- —The same profile is used across T Series models for cross-compatibility of tubes
- —Yes — the shield uses a snap-clip plastic bearing at each end, releasable with a screwdriver
- —Removing the shield takes under 5 minutes without dismounting the shaft
- —Always refit and secure the safety chains after any maintenance on the shaft or shield
- —MP (maximum peak torque) is the shaft’s rated momentary overload capacity
- —It applies during start-up, slug loads, or sudden implement jams
- —Operating continuously at or above MP will shorten cross-kit life — fit a torque limiter if slug loads are frequent
- —Upper series T8, T9, and T10 are rated for tractors up to 200 hp at 540 rpm
- —For tractors above 200 hp, consider industrial SWC or SWP cardan shaft series
- —Always match series to rated PTO torque, not engine horsepower
- —Yes — T Series shafts are compatible with any tractor with a standard 540 or 1,000 rpm PTO output
- —CVT and IPTO tractors produce variable speed; confirm the torque rating covers the full output range
- —For electronically controlled PTO with torque sensing, contact us to confirm shaft selection
