Overview
Product Description
Series 3 Quick Release Splined Yoke is the tractor-end connection for Series 3 PTO drive shafts (T3/L3) in the 22–35 hp tractor class. At this series, the 27 mm cross-kit pin diameter introduces a new bearing family — one shared with Series 4, simplifying the cross-kit inventory for workshops stocking both. The Z6 6-spline interface is unchanged from Series 1 and 2, maintaining full compatibility with all standard 540 rpm PTO stubs.
Series 3 is the highest-volume yoke in the compact-to-mid transition range. It covers the majority of mid-size rotary tillers, post hole diggers, and compact round baler tractor connections on 25–35 hp tractors in the South American market. The push-pin quick release is particularly valued in post hole digger applications where the operator moves the tractor frequently and needs to disconnect the PTO shaft rapidly before repositioning.
For the complete yoke series compatibility reference and cross-kit part numbers, see the Quick Release Yoke category page. Compatible T Series and L Series drive shafts are listed on the PTO Drive Shaft range 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.
27×70 mm Cross-Kit Seat
Precision-machined cross-kit bearing cup bores hardened to accept 27 mm pin diameter needle-roller cross-kit cups. Compatible with Series 3 cross kits used across T3 / L3 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 3 Z6 yoke — tractor-end connection for 22–35 hp implements
Mid-Size Rotary Tillers
1.4–1.6 m rotary tillers on 22–35 hp tractors. Series 3 Z6 is the most common yoke specification for mid-range compact tractor tilling applications in the Brazilian agricultural market.
Compact Round Baler Connection
Tractor-end yoke for small round balers on 25–35 hp tractors. The push-pin quick release allows the operator to disengage rapidly when clearing baler blockages without reaching for tools.
Post Hole Digger Drive
PTO post hole auger drives on 20–35 hp tractors. Series 3 Z6 handles the high start-up torque of auger engagement in compact soils while allowing fast yoke disconnection when repositioning the auger.
Installation Procedure
Verify Series and Spline
Confirm your PTO shaft is Series 3 (27×70 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.
