Splined Yoke 01\u2011Push Pin<\/h2>\n

Precision-engineered push-pin splined yokes for agricultural and industrial PTO drive shafts \u2014 built for British farming conditions and heavy-duty power transmission applications across the UK and Europe.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n

\"Yoke\"The Splined Yoke 01-Push Pin is a core connection component in PTO drive shaft assemblies, designed to deliver fast, tool-free coupling and reliable torque transfer in demanding field and workshop environments. Unlike conventional collar-locking yokes, the push-pin mechanism allows operators to engage and disengage the PTO shaft from a tractor or implement in seconds \u2014 without spanners, without struggle, and without interrupting the work cycle. This matters enormously on British farms, where time efficiency and mechanical reliability are non-negotiable across seasons. Whether you are running a rotary cultivator across Yorkshire clay soils, driving a slurry tanker pump in the Scottish Borders, or powering a baler in the Welsh valleys, the push-pin splined yoke delivers the connection security your operation depends upon. The component is manufactured from high-grade alloy steel, precision splined to exacting dimensional standards, and surface-treated for corrosion resistance \u2014 a quality standard that UK agricultural engineers and machinery distributors have come to rely on.<\/p>\n

Why Engineers Specify the Push-Pin Splined Yoke<\/h2>\n

The push-pin design addresses a longstanding frustration in PTO shaft management: the time and effort required to change implements during a working day. On mixed arable and livestock farms across England and Wales, a tractor may be coupled to three or four different implements within a single shift. Every second spent wrestling with a locked collar is productive time lost. The Splined Yoke 01-Push Pin eliminates that friction entirely, allowing a single-handed release and engagement cycle that keeps field operations moving. Beyond convenience, the design engineering behind this yoke ensures the push-pin locking mechanism does not compromise joint integrity under load \u2014 the pin seats positively within a machined recess in the tractor PTO stub, maintaining concentricity and preventing axial play under torque reversal conditions common in loader and baler applications.<\/p>\n

\n
\n
\u26a1<\/div>\n

Tool-Free Release<\/h3>\n

Single-action push-pin mechanism allows rapid coupling and decoupling without any tools \u2014 critical for high-frequency implement changes on UK mixed farms.<\/p>\n<\/div>\n

\n
\ud83d\udd28<\/div>\n

High-Grade Alloy Steel<\/h3>\n

Machined from forged alloy steel with precision spline profiles, delivering high fatigue resistance and consistent torque capacity across the full operating load range.<\/p>\n<\/div>\n

\n
\ud83d\udcc8<\/div>\n

Wide Series Range<\/h3>\n

Ten series variants (1.0501B through 38.0501B) cover a broad spectrum of PTO shaft sizes, matching the diversity of tractor and implement pairings found across British agricultural operations.<\/p>\n<\/div>\n

\n
\ud83d\udd12<\/div>\n

Positive Locking Under Load<\/h3>\n

The pin seating geometry prevents accidental disengagement during torque reversal or vibration \u2014 a safety-critical requirement for mower-conditioners, hedge cutters, and rotary cultivators.<\/p>\n<\/div>\n

\n
\ud83c\udf1e<\/div>\n

Corrosion-Resistant Finish<\/h3>\n

Surface treatment protects against the wet, muddy, and saline environments typical of UK coastal farming areas and winter field operations in northern England and Scotland.<\/p>\n<\/div>\n

\n
\u2699<\/div>\n

Universal 1 3\/8″ Z6 Interface<\/h3>\n

Standardised to the 1 3\/8″ 6-spline profile (1 3\/8″Z6) used by the majority of European and British tractor manufacturers, ensuring cross-brand compatibility straight from the box.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

Materials, Operating Principle & Application Scenarios<\/h2>\n

Every Splined Yoke 01-Push Pin begins as a hot-forged alloy steel billet \u2014 typically 20CrMnTi or equivalent grade \u2014 which provides the combination of surface hardness and core toughness needed to survive repeated shock loading without fatigue cracking. After forging, the yoke bore is precision-broached to produce a clean 6-spline internal profile dimensioned to 1 3\/8″ Z6 standard. The push-pin housing is machined as an integral part of the yoke body rather than added as a separate pressed insert, which eliminates a common failure point seen in lower-specification competitors. A spring-loaded stainless steel pin sits within a hardened cross-bore; when the yoke is pushed onto the PTO stub shaft, the pin snaps into a mating groove in the stub, creating a positive axial lock. To release, the operator simply depresses the pin button \u2014 typically requiring no more than 5\u00a0kg of finger force \u2014 and the yoke slides cleanly free. This mechanism remains reliable across a service temperature range of -20\u00a0\u00b0C to +80\u00a0\u00b0C, covering the full climate range encountered across all UK agricultural regions from Orkney to Cornwall. Application scenarios include rotary tillers, flail mowers, fertiliser spreaders, slurry pumps, round balers, straw choppers, and grain augers \u2014 wherever a reliable, repeatable PTO connection is required.<\/p>\n

Case Study \u2014 UK Agricultural Contracting<\/div>\n

Riverside Agri-Services Ltd, Morpeth, Northumberland<\/h3>\n

Riverside Agri-Services operates a fleet of twelve tractors providing contract cultivation, drilling, and baling services across 4,200 hectares of arable land in Northumberland and County Durham. Their previous PTO yoke supplier provided collar-type yokes that required a spanner for removal \u2014 a particular problem during autumn drilling campaigns when operators routinely switch between subsoilers, power harrows, and seed drills multiple times per day.<\/p>\n

Following a trial of the Splined Yoke 01-Push Pin (series 5.0501B and 6.0501B) across two tractors in spring 2024, the business converted its entire fleet. The engineering team at Riverside reported that implement changeover time per machine dropped from an average of 8 minutes to under 90 seconds. Over a 60-day autumn campaign with 12 tractors, this translated to roughly 63 hours of recovered productive time \u2014 a measurable improvement to their seasonal output without any additional capital investment.<\/p>\n

What is the difference between a push-pin splined yoke and a collar-lock yoke for PTO drive shafts used on UK farms?<\/div>\n
A push-pin splined yoke uses a spring-loaded pin that snaps into a machined groove on the tractor PTO stub, allowing tool-free coupling and decoupling in seconds. A collar-lock yoke requires sliding or rotating a locking collar \u2014 which often needs a spanner on older designs. For UK farms running mixed implement programmes, the push-pin mechanism saves significant time during busy seasonal operations such as autumn drilling or hay-making campaigns.<\/div>\n<\/div>\n
\n
Which series of Splined Yoke 01-Push Pin is the right fit for a New Holland T6 tractor used in East Anglia for arable cultivation?<\/div>\n
For a New Holland T6 series tractor running standard 1 3\/8 inch 6-spline PTO with cultivation implements, the 5.0501B or 6.0501B series are most commonly specified, covering the mid-range shaft diameters used with power harrows and rotary cultivators in the Fenland and Lincolnshire Wolds area. We recommend confirming your implement gearbox input shaft dimensions before ordering to ensure the correct series selection.<\/div>\n<\/div>\n
\n
How much do push-pin splined yokes cost and can I get a bulk price quote for a fleet of twelve tractors based in Scotland?<\/div>\n
Pricing depends on series selection, quantity, and any custom specification requirements. For fleet orders of twelve or more tractors \u2014 common among Scottish contracting businesses operating in Perthshire, Angus, or the Borders \u2014 volume pricing is available and typically offers a meaningful reduction on the unit cost. Email sales@pto-drive-shafts.com with your tractor model list, series numbers required, and your delivery postcode to receive a tailored quotation.<\/div>\n<\/div>\n
\n
Where can I find a reliable UK supplier of splined PTO yokes with push-pin release for agricultural machinery distributors in the Midlands?<\/div>\n
pto-drive-shafts.com supplies the full Splined Yoke 01-Push Pin range to agricultural machinery dealers and parts distributors throughout the UK Midlands \u2014 including Warwickshire, Shropshire, Nottinghamshire, and Derbyshire. We support trade accounts with consistent lead times, competitive pricing, and technical support for product selection. Contact us to discuss a distributor or trade account arrangement for your business.<\/div>\n<\/div>\n
\n
When should I replace my PTO drive shaft splined yoke and what are the warning signs of wear on British farm machinery?<\/div>\n
Replace a splined yoke when you notice axial play greater than 1 to 2 mm on the tractor PTO stub, visible fretting or corrosion pitting on the spline teeth, a push-pin that no longer clicks positively into engagement, or any cracking around the yoke bore or arm welds. On UK farms running in wet clay soils \u2014 particularly in Somerset, Cheshire, and lowland Scotland \u2014 more frequent inspection is advisable, at minimum at the start of each seasonal campaign.<\/div>\n<\/div>\n
\n
Can I order a custom-length splined yoke with a non-standard bore size for an OEM implement manufacturer based in the UK?<\/div>\n
Yes. We offer custom engineering for OEM implement manufacturers across the UK, covering non-standard bore diameters, modified overall lengths, custom surface treatments, and alternative push-pin spring preload specifications. Development quantities from 50 pieces are supported, with series production available beyond that. Contact sales@pto-drive-shafts.com with your technical drawing or sample component for an initial engineering assessment and quotation.<\/div>\n<\/div>\n<\/div>\n<\/div>\n
