Series 4 PTO Shaft 1-3/8" 6 Spline

This Series 4 PTO driveline shaft connects tractors to implements using a 1-3/8 inch 6-spline tractor end and a matching round implement end. It is built from 20CrMnTi carburised steel universal joints and a Q345 steel tube inside a protective shield. The assembly carries CE certification for agricultural use. It suits operators needing a standard Series 4 connection for rotary cutters or finish mowers.

Telescoping Length 39 to 55 Inches

The shaft compresses to 39 inches (1000 mm) and extends to 55 inches (1400 mm) via a telescoping steel tube. This range covers many tractor-to-implement distances but cannot span setups requiring a shorter collapsed length or a longer extended reach. The fixed yoke geometry also limits angular misalignment during operation. Users must verify their specific machine spacing before fitting.

Power Ratings at 540 and 1000 RPM

At 540 rpm the driveline handles 35 hp (26 kW) with 460 Nm torque; at 1000 rpm it delivers 53 hp (39 kW) with 360 Nm torque. These figures suit typical brush hogs and light tillage tools within the Series 4 class. Heavier implements demanding higher continuous torque or power will exceed the shaft's rated capacity. The spline and round-end interface also restricts use to compatible implements only.

Questions about this item

Should I choose the 39-inch compressed or 55-inch extended length for my tractor setup?

The shaft telescopes from 39 inches compressed to 55 inches extended, so measure your tractor-to-implement distance and select a length that stays within that range during operation.

What do the 35 hp at 540 rpm and 53 hp at 1000 rpm ratings mean for my mower?

At 540 rpm the shaft handles 35 hp and 460 Nm torque; at 1000 rpm it handles 53 hp and 360 Nm torque, so match your tractor PTO speed to the implement's power requirement.

How does the 1-3/8-inch 6-spline tractor end and round implement end connect to my equipment?

The tractor end uses a standard 1-3/8-inch 6-spline yoke with a locking pin, while the implement end is a 1-3/8-inch round bore that fits matching round-shaft implements.
