Overview
Product Description
Series 8 Quick Release Splined Yoke steps to the 35 mm cross-kit pin diameter — a significant increase from the 30.2 mm family of Series 5, 6, and 7. The 35×94 mm cross-kit seat provides the bearing capacity for 60–90 hp large square baler and heavy forage harvester applications. Workshop tooling at 35 mm is separate from 30.2 mm tools — pressing fixtures and snap-ring pliers must be matched to the 35 mm pin. Workshops already equipped for T8 or S8 cross-kit service have the correct tools for Series 8 yoke cross-kit replacement.
Series 8 Z6 is the standard tractor-end yoke for large square balers on 65–90 hp tractors in the European-specification implement market. The Italian reference AB8 (Bondioli & Pavesi catalog) and Weasler 102-0806 are the most commonly cited cross-references when sourcing Series 8 Z6 replacements for European OEM equipment operating in South America.
For confirming Series 8 compatibility with a specific implement, provide the implement make and model to Ever-Power Drive Line. Series 8 Z6 yokes are also compatible with Series 8 cross kits from the Cross Kit product page.
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.
35×94 mm Cross-Kit Seat
Precision-machined cross-kit bearing cup bores hardened to accept 35 mm pin diameter needle-roller cross-kit cups. Compatible with Series 8 cross kits used across T8 / S8 / G8 / S38 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 8 Z6 yoke — tractor-end connection for 60–90 hp implements
Large Square Balers
Series 8 Z6 is the tractor-end yoke for large square balers on 60–90 hp tractors. The 35×94 mm cross-kit seat handles the sustained plunger and knotter drive demands of high-output square baling at the 1-3/8″ Z6 spline interface.
Heavy Forage Harvesters
Pull-type forage harvester tractor-end connection on 70–90 hp tractors requiring the Series 8 cross-kit torque class. Quick release push-pin allows harvester disconnection for headland turns without tool access.
Heavy Rotary Cutters
Heavy-duty industrial rotary cutters and mulchers on 70–90 hp tractors. Series 8 Z6 provides the cross-kit capacity for sustained mulching duty with the push-pin quick release for operator convenience.
Installation Procedure
Verify Series and Spline
Confirm your PTO shaft is Series 8 (35×94 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.
