Product Description<\/h2>\n

Series 3 Quick Release Splined Yoke is the tractor-end connection for Series 3 PTO drive shafts (T3\/L3) in the 22\u201335 hp tractor class. At this series, the 27 mm cross-kit pin diameter introduces a new bearing family \u2014 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.<\/p>\n

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\u201335 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.<\/p>\n

For the complete yoke series compatibility reference and cross-kit part numbers, see the Quick Release Yoke category page<\/a>. Compatible T Series and L Series drive shafts are listed on the PTO Drive Shaft range page<\/a>.<\/p>\n

Quick Release Mechanism — How It Works<\/h2>\n
\"Quick<\/p>\n

The push-pin spring-loads into the PTO stub engagement groove. Press the collar to release.<\/p>\n<\/div>\n

\n
\n
1<\/div>\n

Push Collar Forward<\/p>\n

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.<\/p>\n<\/div>\n

\n
2<\/div>\n

Slide Yoke Onto Stub<\/p>\n

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.<\/p>\n<\/div>\n

\n
3<\/div>\n

Release \u2014 Click Confirms Lock<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n

Dimensional Drawing — A \/ B \/ C \/ D Reference<\/h2>\n

Key Features<\/h2>\n
\n
\n
<\/div>\n
\n

Push-Pin Quick Release<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

1-3\/8″ Z6 Spline Bore<\/p>\n

Standard 540 rpm agricultural interface \u2014 fits all Z6 PTO stubs worldwide. The bore is induction-hardened for resistance to spline wear during frequent engagement and release cycles.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

27\u00d770 mm Cross-Kit Seat<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

20CrMnTi Forged Steel Body<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Retention Spring and Collar<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

CE Certified \u2014 LGPD Ready<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Typical Applications<\/h2>\n
\"Series<\/p>\n

Series 3 Z6 yoke — tractor-end connection for 22\u201335 hp implements<\/p>\n<\/div>\n

\n
\n

Mid-Size Rotary Tillers<\/p>\n

1.4\u20131.6 m rotary tillers on 22\u201335 hp tractors. Series 3 Z6 is the most common yoke specification for mid-range compact tractor tilling applications in the Brazilian agricultural market.<\/p>\n<\/div>\n

\n

Compact Round Baler Connection<\/p>\n

Tractor-end yoke for small round balers on 25\u201335 hp tractors. The push-pin quick release allows the operator to disengage rapidly when clearing baler blockages without reaching for tools.<\/p>\n<\/div>\n

\n

Post Hole Digger Drive<\/p>\n

PTO post hole auger drives on 20\u201335 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.<\/p>\n<\/div>\n<\/div>\n

Installation Procedure<\/h2>\n
\n
\n
1<\/div>\n

Verify Series and Spline<\/p>\n

Confirm your PTO shaft is Series 3 (27\u00d770 mm cross kit) and your tractor PTO stub is Z6 (1-3\/8″ 6-spline). Count the splines if in doubt.<\/p>\n<\/div>\n

\n
2<\/div>\n

Clean the Stub<\/p>\n

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.<\/p>\n<\/div>\n

\n
3<\/div>\n

Press Collar and Engage<\/p>\n

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.<\/p>\n<\/div>\n

\n
4<\/div>\n

Release and Verify Click<\/p>\n

Release the collar. You should hear and feel the push-pin snap into the stub engagement groove. Tug the yoke firmly \u2014 it must not slide back without pressing the collar.<\/p>\n<\/div>\n

\n
5<\/div>\n

Anchor Safety Chain<\/p>\n

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.<\/p>\n<\/div>\n<\/div>\n
