Overview
Product Description
S42 introduces the 38 mm cross-kit pin diameter — the fourth and largest standard pin size in the S Series, between the 35 mm family (S8/S9/S38) and the 41 mm S10. The 38×102 mm cross kit delivers 1,440 Nm at 540 rpm and 2,650 Nm peak, placing S42 above S9 and below S10 in the torque hierarchy. S42 is specified by European OEM lines where the S9 capacity is marginal and the S10 tube is oversized for the implement housing design.
The 38 mm pin diameter is unique to S42 in the standard S Series — workshop tooling (pressing fixtures, snap-ring pliers, bearing cups) must be sized for the 38 mm pin and is not compatible with either the 35 mm or 41 mm tools. For workshops that service S42, S9, and S10, three separate tool sets are required. This is a practical consideration for service network planning in markets where the full S Series range is in use.
S42 is a higher-specification series with lower production volumes than S6–S9. Stock availability should be confirmed before committing to delivery timelines. For regular procurement — distributors, OEM contracts, or fleet maintenance programs — a blanket order arrangement provides priority allocation and fixed lead times.

Key Features
Star Tube Profile — Six-Lobe Bore
The star (six-lobe) tube cross-section provides the highest torsional rigidity per unit outer diameter of any standard agricultural PTO tube profile. Specified by European implement OEMs for input housings machined to star bore dimensions — incompatible with triangular or lemon tube profiles.
Sealed Cross-Kit Bearings — IP67
Double-lip sealed needle-roller bearing cups, factory-filled with EP2 lithium complex grease. Grease nipple accessible with shield in place. Rated for 350+ hours between maintenance interventions in standard field conditions.
CE Safety Shield — Standard
CE-marked UV-stabilised HDPE bellows guard matched to S Series tube outer diameter. Spring-clip anchors and chain points at both ends. OECD Code 4 compliant. Included as standard with every S Series unit.
Forged 20CrMnTi Steel Yokes
Drop-forged chromium-manganese-titanium alloy steel yokes, normalised and induction-hardened at bearing seat journals. Designed for sustained peak torque applications in large baler and forage harvester duty cycles.
All Spline Standards Available
1-3/8 inch Z6 (540 rpm), 1-3/4 inch Z20 (1,000 rpm), and 1-3/8 inch Z21 push-pin or bolt-clamp yokes. Both ends specified independently at order.
CE + ISO Certification Package
CE Declaration of Conformity, ISO 9001:2015, TS/16949 process certificate, LGPD compliance documentation. SGS third-party batch inspection available on contract orders.
Typical Applications
S Series star tube — 90–130 hp tractor class applications
Large Square Balers — 100–130 hp
High-density large square baler plunger and knotting drive in the 100–130 hp class. S42 fills the torque gap between S9 (1,240 Nm) and S10 (1,905 Nm), providing a more precisely sized shaft for implements demanding 1,200–1,440 Nm continuous.
Heavy-Duty Forage Harvesters — 100 hp+
Large pull-type forage harvester flywheel drive where S9 (35×106.5 mm) is approaching its rated limit and S10 (41×118 mm) is overspecified for the implement housing dimensions.
Industrial Mulchers and Chippers
Heavy-duty PTO-driven mulchers and wood chippers requiring sustained 1,200–1,440 Nm at 540 rpm. The 38 mm cross-kit pin diameter provides the bearing capacity for this duty class in the star tube profile.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Confirm Torque Class
Calculate implement demand (Nm). Add 20% safety margin. Select the lowest S Series where Nm@540 (or Nm@1000) exceeds the adjusted figure.
Adjust Working Length
Measure coupling centre distance with implement attached. Verify 50 mm min tube overlap at full extension, 80 mm at full compression.
Engage Yoke Connections
Push-pin yoke: engage at PTO stub and confirm audible click and positive retention. Clamp yoke: torque to manufacturer specification.
Anchor Safety Chains
Connect tractor-side chain to guard or frame; implement-side chain to implement body. Verify taut at working height.
Grease Before First Use
Apply EP2 lithium complex NLGI 2 grease (2–3 pumps) to both cross-kit nipples. Service every 8 hours; 4 hours in wet or abrasive conditions.
Frequently Asked Questions
