In square baling operations, the tractor-baler articulation angle changes continuously \u2014 particularly during headland turns and when working across cambers or gateways. Conventional single Cardan joints produce a velocity fluctuation that increases sharply beyond about 15 degrees, generating torsional shock loads in the driveline at every revolution. The double-Cardan CV geometry used in this Size 6 assembly cancels the secondary velocity error internally, so the baler flywheel and gearbox input shaft receive smooth, pulse-free torque up to the rated maximum articulation angle of approximately 35 degrees. This protection is particularly valuable on the high-inertia flywheels fitted to large-format square balers like the Hesston 4690S.<\/p>\n<\/div>\n<div style=\"flex: 1 1 255px; background: linear-gradient(135deg,#fdf5e8,#f5e8d0); border-radius: 10px; padding: 18px; box-sizing: border-box; border-left: 4px solid #f5a623;\">\n<p>Materials &amp; Construction Quality<\/p>\n<p style=\"font-size: 0.86rem; line-height: 1.8; color: #2c3a4a; margin: 0;\">Drive tubes are cold-drawn from high-strength structural steel with a minimum yield strength of 430\u00a0N\/mm\u00b2, formed to the Series 6 star (or lemon) telescopic profile that provides the required torsional rigidity for heavy baling applications. Cross journals are forged from 20CrMnTi alloy steel, carburised and induction-quenched to a surface hardness of 58\u201362\u00a0HRC, delivering excellent fatigue resistance in the cyclic loading environment of square baler operation. Yoke forgings are manufactured from 45# medium carbon steel and treated with a zinc phosphate conversion coating followed by yellow chromate sealant \u2014 a corrosion protection specification well-suited to the wet and contaminated field conditions typical of UK harvest and autumn work seasons.<\/p>\n<\/div>\n<div style=\"flex: 1 1 255px; background: linear-gradient(135deg,#edf7f0,#d5f0de); border-radius: 10px; padding: 18px; box-sizing: border-box; border-left: 4px solid #27ae60;\">\n<p>Application Scenarios in the Field<\/p>\n<p style=\"font-size: 0.86rem; line-height: 1.8; color: #2c3a4a; margin: 0;\">The primary application is large-format square baling \u2014 cereal straw, hay, and haylage \u2014 using the Hesston 4690 and 4690S across the UK&#8217;s arable heartland. The cross-compatible Case-IH 8530 and 8545 fitment also makes this shaft a practical stock item for agricultural dealers serving mixed baler fleets. Beyond dedicated baling operations, the Size 6 CV driveline specification is appropriate for any high-throughput contracting application where the PTO shaft operates under near-continuous duty cycles over extended harvest windows. The robust safety guard and chrome-finish corrosion protection mean the shaft also performs reliably in livestock and mixed farming environments where equipment is exposed to slurry, moisture, and aggressive cleaning regimes.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 COMPATIBILITY TABLE \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: #eef2f7; padding: 14px 18px 26px; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(1.15rem,3.4vw,1.75rem); color: #06192e; border-left: 4px solid #f5a623; padding-left: 14px; margin: 0 0 14px; font-weight: bold;\">Compatible Machine Reference Guide<\/h2>\n<div style=\"overflow-x: auto; width: 100%; max-width: 100%; min-width: 100%; -webkit-overflow-scrolling: touch; box-sizing: border-box;\">\n<table style=\"width: 100%; max-width: 100%; min-width: 100%; border-collapse: collapse; font-size: 0.87rem; background: #ffffff; border-radius: 10px; overflow: hidden; box-shadow: 0 3px 14px rgba(6,25,46,0.09); box-sizing: border-box;\">\n<thead>\n<tr style=\"background: #06192e;\">\n<th style=\"padding: 12px 14px; text-align: left; color: #f5a623; font-weight: bold; white-space: nowrap;\">Brand<\/th>\n<th style=\"padding: 12px 14px; text-align: left; color: #f5a623; font-weight: bold; white-space: nowrap;\">Model<\/th>\n<th style=\"padding: 12px 14px; text-align: left; color: #f5a623; font-weight: bold; white-space: nowrap;\">OEM \/ Driveline Ref.<\/th>\n<th style=\"padding: 12px 14px; text-align: left; color: #f5a623; font-weight: bold;\">Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom: 1px solid #dce8f2;\">\n<td style=\"padding: 11px 14px; color: #06192e; font-weight: bold;\">Hesston<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">4690 \/ 4690S<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">BPCV612100101<\/td>\n<td style=\"padding: 11px 14px; color: #374a5c;\">Primary application \u2014 verify driveline version on machine label<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #dce8f2; background: #f6f9fc;\">\n<td style=\"padding: 11px 14px; color: #06192e; font-weight: bold;\">Hesston<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">4590<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">Bondioli series<\/td>\n<td style=\"padding: 11px 14px; color: #374a5c;\">Confirm compressed length before installation<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #dce8f2;\">\n<td style=\"padding: 11px 14px; color: #06192e; font-weight: bold;\">Hesston<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">4570<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">Bondioli Heavy Duty<\/td>\n<td style=\"padding: 11px 14px; color: #374a5c;\">Heavy-duty driveline variant<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #dce8f2; background: #f6f9fc;\">\n<td style=\"padding: 11px 14px; color: #06192e; font-weight: bold;\">Case-IH<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">8530<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">Bondioli Heavy Duty<\/td>\n<td style=\"padding: 11px 14px; color: #374a5c;\">Heavy-duty driveline specification<\/td>\n<\/tr>\n<tr style=\"background: #f6f9fc;\">\n<td style=\"padding: 11px 14px; color: #06192e; font-weight: bold;\">Case-IH<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">8545<\/td>\n<td style=\"padding: 11px 14px; color: #1a2535;\">Bondioli series<\/td>\n<td style=\"padding: 11px 14px; color: #374a5c;\">Serial number below CFH0045577 only<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<h3><\/h3>\n<h3>Engineering Drawings<\/h3>\n<h4><strong>Square Balers PTO Shaft\uff1a<\/strong><\/h4>\n<p><img decoding=\"async\" style=\"width: 100%; max-width: 100%; min-width: 100%; display: block; border-radius: 6px; border: 1px solid #1a4a7a; background: #ffffff;\" src=\"https:\/\/pto-gearboxes.top\/wp-content\/uploads\/2026\/05\/ep-PTO-Shaft-for-Hesston-Square-Balers-4690-4690S-9-1-1.webp\" alt=\"PTO shaft 4690 4690S engineering drawing overall dimensions\" title=\"\"><\/p>\n<p>New CV (Constant Velocity) PTO shaft without implementing yoke, size 6.

Over an eight-week summer harvest window, the two 4690S machines typically process in excess of 12,000 bales of wheat and barley straw running near-continuous daily shifts.<\/p>\n<p style=\"color: #c2d8f0; font-size: 0.87rem; line-height: 1.82; margin: 0 0 13px;\">In late July 2024, a catastrophic CV joint failure on one of the 4690S drivelines halted baling mid-harvest. The original shaft had reached the end of its service life, and the local dealership quoted a six-day wait at a price the operations manager described as &#8220;well above the odds.&#8221; An enquiry was placed with our team late that afternoon. A complete replacement PTO shaft for Hesston 4690S was despatched the following morning, arrived by 9\u00a0AM courier, and was fitted by the farm&#8217;s in-house mechanic in under two hours. The baler returned to the field the same day \u2014 preventing an estimated three days of operational downtime valued at over \u00a318,000 in lost contracting income.<\/p>\n<div style=\"background: rgba(245,166,35,0.09); border-left: 3px solid #f5a623; padding: 12px 16px; border-radius: 0 8px 8px 0;\">\n<p style=\"color: #f7dc8e; font-size: 0.89rem; font-style: italic; margin: 0; line-height: 1.7;\">&#8220;The quality was indistinguishable from the original Bondioli shaft, and the price came in nearly 40% below the dealer quote.

Square baling is one of the most time-critical operations on any arable farm: a broken PTO shaft during peak harvest can halt the entire operation, expose cut crops to weather risk, and result in financial losses that far exceed the cost of the failed part \u2014 particularly for contracting businesses operating under fixed-fee agreements with landowners and farm managers.<\/p>\n<p style=\"font-size: 0.96rem; line-height: 1.85; color: #2c3a4a; margin: 0 0 14px;\">Our supply chain is structured specifically to give UK farm merchants, agricultural dealerships, and direct farm buyers rapid access to correct-specification replacement PTO shafts at competitive B2B pricing. We hold stock of the Hesston 4690 and 4690S CV driveline and regularly supply customers across England, Scotland, and Wales \u2014 including farm machinery workshops in Yorkshire and Lincolnshire, dealers covering mixed Hesston and Case-IH fleets in the East Midlands, and individual farm buyers who prefer to manage their own parts inventory ahead of each baling season.

This matches the Bondioli &amp; Pavesi reference BPCV612100101. To verify tractor compatibility, count the splines on your tractor&#8217;s PTO stub and measure the stub diameter \u2014 if it reads six splines and 1\u20113\/8 inches, the shaft will engage directly. At least three driveline versions have been fitted to this model series over its production life, so physically measuring the existing shaft and noting any part numbers on the original driveline label is strongly recommended before ordering.<\/p>\n<\/div>\n<\/details>\n<details style=\"width: 100%; max-width: 100%; min-width: 100%; background: #f6f9fc; border-radius: 8px; margin: 0 0 10px; border: 1px solid #dce8f2; overflow: hidden; box-sizing: border-box;\" open=\"open\">\n<summary style=\"padding: 15px 18px; font-weight: bold; font-size: 0.91rem; color: #06192e; cursor: pointer; display: block;\">How much does a replacement PTO shaft for a Hesston 4690 baler typically cost in the UK, and how do I get a trade price quote from a manufacturer?<\/summary>\n<div style=\"padding: 2px 18px 16px; border-top: 1px solid #dce8f2;\">\n<p style=\"font-size: 0.86rem; line-height: 1.82; color: #2c3a4a; margin: 10px 0 0;\">Pricing for the Hesston 4690 PTO shaft depends on order volume, current logistics costs to your UK delivery address, and any applicable trade account status.

At the angles commonly reached when a large square baler swings on a field headland \u2014 potentially 25\u201335 degrees \u2014 these fluctuations create severe torsional shock loads that accumulate rapidly into fatigue damage in cross journals, bearings, and gearbox components. A double-Cardan CV assembly places two Cardan joints in series with a centring ball and socket that cancels the secondary velocity error, so the output rotates at exactly the same speed as the input regardless of operating angle up to the rated limit. For the high-inertia flywheel on a Hesston 4690S, this difference translates directly into extended component life and a smoother, more consistent baling output through every working hour.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<p><!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 CTA \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: linear-gradient(135deg,#06192e,#0b3361); padding: 14px 18px 36px; box-sizing: border-box; text-align: center;\">\n<p><img decoding=\"async\" style=\"width: 100%; max-width: 100%; min-width: 100%; display: block; border-radius: 10px; box-shadow: 0 12px 44px rgba(0,0,0,0.5); margin: 0 0 24px;\" src=\"https:\/\/pto-gearboxes.top\/wp-content\/uploads\/2026\/05\/ep-PTO-Shaft-for-Hesston-Square-Balers-4690-4690S-8-1-1.webp\" alt=\"PTO shaft Hesston 4690 4690S packaged and ready for UK despatch\" title=\"\"><\/p>\n<h2 style=\"color: #ffffff; font-size: clamp(1.3rem,4vw,2rem); font-weight: 800; margin: 0 0 12px; line-height: 1.28;\">Ready to Order or Need Technical Confirmation?<\/h2>\n<p style=\"color: #b6d4ef; font-size: clamp(0.86rem,2.4vw,0.98rem); margin: 0 0 22px; line-height: 1.75;\">Our PTO shaft application engineers are available to confirm part fitment, provide current pricing, and arrange fast UK delivery.
