Overview
Product Description
T7N carries identical torque ratings to T7 but uses a narrow-profile tube for specific European implement input shaft geometries. The cross kit is 35×94 mm — entirely different from T7’s 30.2×106.5 mm. T7N and T7 cross kits are completely non-interchangeable. Always confirm whether the implement manufacturer specifies T7 or T7N before ordering. For the full T Series PTO drive shaft range, see our category page.
T7N occupies a specific OEM-driven niche. The narrow tube profile was introduced by European implement manufacturers — most notably in certain Krone and Claas baler and mower-conditioner models — to accommodate input shaft housings with tighter radial clearances than the standard T7 tube allows. In Brazil, imported Krone and Claas machinery has been present for over two decades, and the T7N replacement requirement has grown as these machines age into the high-hours replacement cycle.
Ever-Power Drive Line stocks both T7 and T7N independently, with clearly differentiated part numbers, to prevent field substitution errors that are common when importers combine these two series in a single stock SKU. The T7N cross kit (7N.01, 35×94 mm) differs from the T7 cross kit in both pin diameter and journal length. Buyers ordering replacement cross kits must specify the exact series and confirm the existing shaft tube profile before ordering. Full CE, ISO 9001, and TS/16949 documentation for Brazil INMETRO and LGPD compliance. For technical enquiries, contact Ever-Power Drive Line.

Key Features
Precision Forged Yoke Bodies
20CrMnTi forged under 1,500-ton press, normalised, induction-hardened at journal seats. Rated for shock loads to peak torque without deformation.
Sealed Greaseable Cross Kits
Sealed needle rollers with grease nipple on each cross arm. Service interval extends to 50 hours in normal soil conditions.
UV-Stabilised HDPE Shield
Yellow HDPE bellows UV-stabilised for tropical and subtropical environments. Spring-clip anchors with integrated safety chain attachment points.
Multi-Profile Yoke Compatibility
1-3/8 inch Z6 (540 rpm), 1-3/4 inch Z20 (1,000 rpm), 1-3/8 inch Z21 all stocked and interchangeable within the same shaft series.
Drawing-Based OEM Production
Customer DXF or DWG reviewed before tooling. Engineering support available. Lead time 25–30 days from drawing approval.
CE + ISO Dual Certification
Manufactured under ISO 9001:2015 and TS/16949 QMS. CE marked per Machinery Directive. SGS third-party inspection on request.
Typical Applications
European-Spec Balers
T7N tube profile matches specific European baler input geometries where standard T7 tube OD creates mechanical interference at the housing.
Mower-Conditioners
High-cycle conditioning roller drive. T7N is required on specific Krone and Claas mower-conditioner models — torque rating identical to T7.
OEM Replacement
Direct replacement for Walterscheid and Bondioli series 7N driveshafts on compatible implements. Cross kit 7N.01 is non-interchangeable with T7.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Torque and Series Selection
Identify PTO rated torque from tractor manual. Select T Series where rated Nm exceeds PTO torque by 20% or more.
Shaft Length Adjustment
With implement at full height: verify 50 mm min tube overlap. At lowest position: verify 80 mm overlap. Cut to length once confirmed.
Yoke Attachment Procedure
Align spline and slide yoke to full engagement until push-pin locks. Test retention by pulling toward tractor. Bolt-clamp: torque to spec.
Safety Chain Connection
Route chain from each shield end bracket to a fixed, non-rotating point. Prevent shield rotation without loading chain during lift.
Lubrication Schedule
Pre-grease all cross-kit nipples with EP2 before operation. 8-hour regrease intervals normal use; halve in sandy or waterlogged soils.
Frequently Asked Questions
- —T Series uses a triangular (trilobular) tube profile — the most common EU agricultural standard
- —L Series uses the same cross kits but with a longer outer tube for extended hitch distances
- —S Series uses a sliding spline without a separate shield, for applications requiring smooth extension
- —Every 8 operating hours under normal field conditions is the standard interval
- —Reduce to 4 hours in wet, sandy, or abrasive soil conditions
- —Use EP2 lithium complex grease only — do not mix with other grease types
- —1-3/8 inch 6-spline (Z6) for 540 rpm PTO output — the most common agricultural configuration
- —1-3/4 inch 20-spline (Z20) for 1,000 rpm PTO output on larger tractors
- —1-3/8 inch 21-spline (Z21) available for specific implement input configurations
- —Yes — CE Declaration of Conformity is supplied with each batch
- —ISO 9001:2015 and TS/16949 quality certificates are available on request
- —SGS third-party inspection can be arranged for large orders
- —Without a torque limiter, the cross kit is the designed failure point — protecting the gearbox
- —Pair this shaft with a shear bolt torque limiter for implements prone to slug loads
- —An overrunning clutch prevents back-drive damage on balers and drum mowers
