Series 6 Slip Clutch PTO Driveline — 40", 1-3/8" 6-Spline, 64 HP

The Braber 69.777.039 is a Series 6 slip clutch PTO driveline that transfers tractor power to an implement while protecting the driveline from overload and shock loads. Built on the BY-PY #6 Series for heavy-duty power transfer, it features a 6-spline 1-3/8" quick-disconnect tractor connection, a 2-disc slip clutch on the implement end, strong triangular-profile shafting, and a 64 HP at 540 RPM rating — in a compact 40" collapsed length. It's a direct replacement for parts 69.000.038 and 69.000.039.

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 2-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 6 driveline, it carries a heavy-duty 64 HP rating in a short 40" package.

Features

BY-PY #6 Series Driveline

A BY-PY #6 Series driveline delivers reliable, heavy-duty power transfer sized for demanding 540 RPM applications.

2-Disc Slip Clutch

A 2-disc slip clutch, rated at 560 RPM, on the 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 45 mm inner and 54 mm outer tube with a 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 6-spline 1-3/8" quick-disconnect tractor connection makes hookup fast and tool-free.

64 HP Rating

Rated for 64 HP at 540 RPM, the driveline handles demanding power transfer with confidence.

40" Collapsed Length

A 40" collapsed length suits closer tractor-to-implement spacing, extending and retracting through operation.

Built for 540 RPM Implements

With its heavy-duty rating and slip-clutch protection, the 69.777.039 is suited for:

• 540 RPM medium tillers
• Other 540 RPM PTO-driven implements within its power rating
• Applications where shock loads and overloads are a risk
• Replacing a worn or damaged 69.000.038 or 69.000.039 driveline
