Overview
Product Description
L4 uses the 27×74.6 mm cross kit — the same 27 mm pin diameter as L3, but 4.6 mm longer journal. This journal extension increases the bearing load distribution and raises the continuous torque rating from 370 Nm (L3) to 460 Nm. For equipment builders replacing L3 units that are approaching their torque limit during peak seasonal loads, L4 provides the upgrade path without requiring a change in tube profile or implement housing modification.
The lemon tube profile on L4 maintains the same outer diameter family as L1 through L3, making L4 the highest-torque option available within this compact tube footprint. Beyond L4, the L5 steps up to the 30.2 mm cross-kit pin diameter and a wider lemon tube — if the implement housing cannot accommodate the L5 tube diameter, L4 is the maximum available torque in the compact lemon profile.
L4 is the most frequently specified series for implement OEMs requiring lemon tube profiles in the 35–45 hp tractor class — a market segment where T4 and T5 triangular tubes are excluded by implement design constraints.

Key Features
Lemon Tube Profile — Compact OD
The lemon (elliptical) tube profile reduces the outer diameter of the telescoping assembly relative to triangular-tube T Series at the same torque class. Fits European OEM implement input housings that exclude triangular tube geometry.
Sealed Cross-Kit Bearings — IP67
Double-lip sealed needle-roller bearing cups, factory-filled with EP2 lithium complex grease. Grease nipple accessible with shield fitted. Designed for 350+ hours between maintenance interventions in normal field conditions.
CE Safety Shield — Standard
CE-marked UV-stabilised HDPE bellows guard. Yellow for field visibility. Spring-clip anchors and chain points at both ends. OECD Code 4 compliant. Supplied as standard on every L Series unit.
Forged 20CrMnTi Steel Yokes
Drop-forged chromium-manganese-titanium alloy steel, normalised and induction-hardened at bearing seat journals. Designed for high peak-load applications without premature bearing seat wear.
All Spline Standards Available
1-3/8 inch 6-spline (ISO 500 Z6), 1-3/4 inch 20-spline (Z20), and 1-3/8 inch 21-spline (Z21). Clamp yoke and push-pin locking both available. Both ends specified independently at order.
CE + ISO Certification Package
CE Declaration of Conformity, ISO 9001:2015, TS/16949 process certificate, and LGPD compliance documentation standard with every shipment. SGS third-party inspection available on contract orders.
Typical Applications
Typical L4 application in 28–45 hp tractor class
Hay Rakes and Tedders
High-angle hay-making implements on 30–45 hp tractors. L4 handles the continuous 460 Nm load of 6–8 rotor tedders and the intermittent slug loads of large-finger rakes within the compact lemon tube footprint.
Mid-Range Round Balers
Round balers in the 30–45 hp class requiring up to 780 Nm peak. L4 absorbs bale eject peaks better than L3 while staying within lemon tube housing clearances that prevent T4 installation.
Slurry Agitators
Tank agitator drives on lagoon spreaders and slurry trailers. Continuous duty, moderate torque, high contamination environment. Sealed L4 cross kits are the correct specification for wet, abrasive operating conditions.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Confirm Torque Class
Match implement demand (Nm) against the table above. Add 20% margin. Select the lowest L Series that meets 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 tractor 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 tractor frame; implement-side chain to implement body. Verify taut with implement at working level.
Grease Before First Use
Apply EP2 lithium complex NLGI 2 grease (2–3 pumps) to both cross-kit nipples. Service every 8 hours. Reduce to 4 hours in wet or abrasive conditions.
Frequently Asked Questions
- —L4 and T4 share the 27 mm cross-kit pin diameter but differ in tube profile: L4 uses lemon, T4 uses triangular
- —L4 tube outer diameter is smaller than T4, allowing use in implement housings that exclude the T4 triangular tube
- —Torque ratings are identical: 460 Nm at 540 rpm, 780 Nm peak
- —Yes — sealed IP67 cross-kit bearings prevent water and slurry ingress during prolonged wet operation
- —Reduce the re-greasing interval from 8 hours to 4 hours in sustained wet conditions
- —The HDPE safety shield is impervious to slurry and manure exposure
- —Yes — overrunning clutches compatible with the L4 splined yoke are available
- —Specify the tractor-end or implement-end position and the required slip torque at order
- —Overrunning clutches are recommended for balers and mowers where implement inertia causes back-drive
- —L4 peak (MP) torque is 780 Nm — this is the maximum momentary torque the shaft can absorb without damage
- —Peak torque occurs during implement start-up, slug loading, and bale eject events
- —Continuous operating torque must not exceed 460 Nm at 540 rpm
- —Send the compressed and extended coupling centre distances, tractor model, and implement model
- —The Ever-Power Drive Line engineering team reviews the DWG and confirms feasibility before production
- —MOQ 50 pieces; lead time 25–30 days from DWG approval
