Overview
Product Description
Series 5 Quick Release Splined Yoke covers the 35–55 hp tractor class where PTO loads increase beyond the Series 4 range — round balers, large rotary mowers, and irrigation pump drives. The 30.2×80 mm cross-kit seat introduces the 30.2 mm pin diameter family, which is shared across Series 5, 6, and 7 yokes, simplifying cross-kit stocking for workshops servicing multiple series. The Z6 6-spline bore maintains full compatibility with standard 540 rpm PTO stubs.
The Series 5 yoke body is larger than Series 4 — the yoke ears are wider to accommodate the 30.2 mm cross-kit cups, and the overall yoke mass is correspondingly higher. This increase in physical size is visible and provides a simple field identification check: if a Series 5 yoke feels heavier and has wider ears than a Series 4, the identification is correct. The push-pin mechanism is identical in principle to lower series but uses a heavier spring for positive retention under higher torque loads.
Series 5 Z6 is stocked alongside compatible T5, L5, and G5 drive shafts. For the complete drive shaft and yoke combination for a 35–55 hp application, see the T Series PTO Drive Shaft range and order the yoke as a separate replacement component.
Quick Release Mechanism — How It Works
The push-pin spring-loads into the PTO stub engagement groove. Press the collar to release.
Push Collar Forward
Press the spring-loaded collar toward the yoke body. This retracts the push-pin from its engagement position, freeing the bore to slide onto the PTO stub.
Slide Yoke Onto Stub
With collar held forward, push the splined bore fully onto the PTO stub until the yoke is fully seated. The splines must be fully engaged before releasing the collar.
Release — Click Confirms Lock
Release the collar. The spring drives the push-pin into the stub engagement groove. An audible click and positive resistance to withdrawal confirms correct locking.

Key Features
Push-Pin Quick Release
Spring-loaded push-pin mechanism allows tool-free connection and disconnection from the PTO stub. Press the collar to retract the pin; release to engage. An audible click confirms positive locking. One-handed operation in field conditions.
1-3/8″ Z6 Spline Bore
Standard 540 rpm agricultural interface — fits all Z6 PTO stubs worldwide. The bore is induction-hardened for resistance to spline wear during frequent engagement and release cycles.
30.2×80 mm Cross-Kit Seat
Precision-machined cross-kit bearing cup bores hardened to accept 30 mm pin diameter needle-roller cross-kit cups. Compatible with Series 5 cross kits used across T5 / L5 / G5 drive shaft assemblies.
20CrMnTi Forged Steel Body
Drop-forged chromium-manganese-titanium alloy steel yoke body, normalised and induction-hardened at the bearing seat bores. Phosphate surface coating provides corrosion resistance in outdoor agricultural conditions. Designed for long-term field service life.
Retention Spring and Collar
Heavy-duty retention spring loaded in the push-pin bore maintains positive engagement under PTO operating vibration. The collar provides a reliable surface for one-handed release in field gloves. Spring tension is calibrated for the series torque class.
CE Certified — LGPD Ready
CE Declaration of Conformity and ISO 9001:2015 documentation included with every shipment. LGPD data handling compliance for Brazil import submissions. SGS third-party inspection available for contract orders.
Typical Applications
Series 5 Z6 yoke — tractor-end connection for 35–55 hp implements
Round Balers — 35–55 hp
Series 5 Z6 is the tractor-end yoke for round balers and large square balers on 35–55 hp tractors. The 30.2×80 mm cross-kit seat transmits the higher continuous and peak torque of baling applications reliably through the push-pin connection.
Rotary Mowers — 1.8–2.4 m
Large rotary mowers on 40–55 hp tractors. Series 5 Z6 handles the higher blade disc inertia of wider mowers and allows quick disconnection when the mower is in transport or for blade maintenance.
Irrigation Pump Drives
Tractor-end connection for PTO-driven centrifugal irrigation pumps on 35–55 hp tractors. Continuous duty application — Series 5 Z6 provides the cross-kit capacity for extended pumping seasons without yoke fatigue.
Installation Procedure
Verify Series and Spline
Confirm your PTO shaft is Series 5 (30.2×80 mm cross kit) and your tractor PTO stub is Z6 (1-3/8″ 6-spline). Count the splines if in doubt.
Clean the Stub
Remove any rust, debris, or old lubricant from the tractor PTO stub and the yoke spline bore before installation. A clean, dry spline surface ensures maximum contact area and positive push-pin engagement.
Press Collar and Engage
Press the collar toward the yoke body to retract the push-pin. Align the yoke spline bore with the stub splines and push firmly until the yoke is fully seated on the stub.
Release and Verify Click
Release the collar. You should hear and feel the push-pin snap into the stub engagement groove. Tug the yoke firmly — it must not slide back without pressing the collar.
Anchor Safety Chain
After the shaft is fully connected (both ends), anchor the safety shield chains to fixed, non-rotating points on the tractor and implement. Never operate without safety chains secured.
Frequently Asked Questions
- —Cross-kit seat bore: 30.2 mm pin diameter, journal 80 mm long
- —Weasler reference 102-0506 or Italian code 1.05.05 confirm Series 5
- —Physically larger and heavier than Series 4 — yoke ears are noticeably wider
- —Yes — both T5 and L5 use the same 30.2×80 mm cross-kit dimensions
- —The yoke cross-kit seat is identical — the tube profile (triangular vs lemon) is in the tube yoke, not the tractor-end yoke
- —Series 5 Z6 is also compatible with G5 (wide-angle CV joint shaft) at the tractor end
- —Every 8 hours with EP2 lithium complex NLGI 2 grease
- —Reduce to 4 hours in wet, sandy, or continuous-duty pump applications
- —Apply 2–3 pump strokes per cross-kit nipple — the yoke nipple is on the cross-kit arm, accessible with the shaft installed
- —Quick release push pin is the standard tractor-end yoke configuration
- —Clamp bolt Series 5 is available for applications where the yoke is permanently mounted
- —Both use the same 30.2×80 mm cross-kit seat — the difference is only in the locking mechanism
- —Series 5 cross kit: 30.2×80 mm, code 5.01
- —Shared with T5, L5, and G5 drive shaft assemblies — one part number covers all three
- —Available individually from the Cross Kit product page
