Series 4 Slip Clutch PTO Driveline — 46", 1-3/8" 6-Spline, Triangular Shafting

The Braber 69.885.446 is a Series 4 slip clutch PTO driveline that transfers tractor power to an implement while protecting the driveline from overload and shock loads. It pairs a 540 RPM, 6-spline 1-3/8" quick-disconnect tractor connection with a 4-disc slip clutch on the implement end, runs on strong triangular-profile telescoping shafting, and measures 46" collapsed — with a protective safety shield for safe operation.

Power Transfer With Built-In Protection

A PTO driveline is the telescoping, universal-jointed shaft that carries power from the tractor's PTO to the implement's gearbox — and this one is engineered to protect what's behind it. Its 4-disc slip clutch gives way under excess torque when an implement overloads or hits a shock load, then re-engages automatically once the load clears. Unlike a shear bolt that breaks and must be replaced, the slip clutch delivers reusable overload protection for the driveline, gearbox, and tractor PTO. As a Series 4 driveline, it's sized for lighter-duty 540 RPM applications.

Features

4-Disc Slip Clutch

A 4-disc slip clutch on the 540 RPM, 6-spline 1-3/8" implement connection provides overload protection that slips and re-engages — no parts to replace after each event.

Triangular-Profile Shafting

Triangular-profile shafting — a 36 mm inner tube (4.5 mm wall) and 43.5 mm outer tube (3.4 mm wall) — telescopes smoothly through the implement's travel while transmitting torque securely, stronger than a plain round shaft.

Quick-Disconnect Tractor Connection

A 540 RPM, 6-spline 1-3/8" quick-disconnect tractor connection makes hookup fast and tool-free.

Safety Shield

A protective safety shield covers the rotating driveline for dependable, safe operation.

46" Collapsed Length

A 46" collapsed length suits a range of tractor-to-implement spacing, extending and retracting through operation.

Built for 540 RPM Implements

With its slip-clutch protection and Series 4 shafting, the 69.885.446 is suited for:

• 540 RPM PTO-driven tillers
• Rotary cutters and brush cutters
• Finish and rotary mowers
• Other lighter-duty 540 RPM implements where shock loads are a risk
