SEO Title (\u224864 chars): Slip Clutch PTO Driveline Shaft | Hesston 1340 & CaseIH Discbine Replacement<\/em><\/p>\n

<\/p>\n

Product Overview<\/h2>\n

This replacement PTO driveline shaft<\/strong> is purpose-built to restore full power transmission on Hesston 1340, 1345, select CaseIH 8312, Massey Ferguson PTD 12, and New Idea 5512 disc mowers. It directly replaces Weasler’s 55N configuration \u2014 80\u00b0 CV on the tractor end, 50\u00b0 CV on the implement end \u2014 with no modification required.<\/p>\n

The integrated slip clutch<\/strong> disengages the drivetrain the moment torque exceeds a safe threshold, then automatically re-engages once the obstruction clears. This single feature eliminates the most common cause of gearbox and PTO stub damage in high-speed disc mowing: sudden contact with rocks, stumps, or soil ridges.<\/p>\n

Both ends carry a 1-3\/8″ 6-spline<\/strong> interface \u2014 the industry-standard fit for tractor PTOs running at 540 RPM. Input shafts are 1.50″ round on the discbine side, matching OEM geometry. If you need a pto driveline shaft<\/em> that installs in under 20 minutes and performs like original equipment, this is the direct answer.<\/p>\n

As a dependable agricultural driveline<\/strong> component, this shaft is manufactured from high-strength steel throughout, with precision-machined yokes and a sealed slip-clutch pack that resists moisture and field contamination.<\/p>\n

Benefits of PTO Driveline Shafts in Heavy Machinery<\/h2>\n

A PTO driveline<\/strong> is the mechanical backbone of any tractor-implement pairing. Without a correctly rated shaft, every horsepower your engine produces is wasted \u2014 or worse, destructive. Here is what a properly specified agricultural driveline actually delivers on the job:<\/p>\n

    \n
  • Direct torque transfer at rated RPM:<\/strong> At 540 RPM, disc mowers and discbines require uninterrupted rotational force. A matched driveline shaft maintains consistent blade speed across uneven terrain, reducing cut-height variation by eliminating driveline windup.<\/li>\n
  • Shock-load absorption:<\/strong> CV joints \u2014 especially wide-angle 80\u00b0 designs \u2014 smooth out the angular velocity fluctuation that occurs when a tractor turns tight headland corners, reducing vibration that would otherwise fatigue gearbox bearings in under a season.<\/li>\n
  • Overload protection via slip clutch:<\/strong> When a disc strikes a hidden rock or soil mound, the clutch pack slips at a preset torque value instead of shearing the PTO stub or breaking an implement gearbox shaft \u2014 repairs that routinely exceed $800\u2013$2,000 in parts alone.<\/li>\n
  • Operator safety:<\/strong> A rotating driveline without a properly fitted shield is a documented entanglement hazard. Full-length plastic shielding and a retention chain are standard on this assembly, satisfying OSHA PTO guarding requirements.<\/li>\n
  • Extended component life:<\/strong> Correctly sized shafts running at their design torque rating show up to 3\u00d7 longer service life compared to undersized replacements subjected to constant over-loading.<\/li>\n<\/ul>\n

    Benefits of CE Certified PTO Driveline Shafts<\/h2>\n

    CE certification on a PTO driveline shaft<\/strong> is not a marketing badge \u2014 it is a documented confirmation that the assembly has been evaluated against EU Machinery Directive 2006\/42\/EC. For B2B buyers and equipment dealers sourcing replacement PTO drivelines, this matters for three concrete reasons:<\/p>\n
