Sigma Power
In models T144, T154 and T174, the Sigma Power control system is optional.
The Sigma Power control system gives extra power for PTO work. When required
for PTO work, the engine will automatically provide up to 30 hp more power.
The Sigma Power activates automatically when the power transferred through the
PTO rises high enough. As a sign of this, the Sigma Power symbol is lit on the
instrument panel.

Both power take-off (PTO) nominal speeds can be used regardless of the type of
shaft installed on the tractor.
Implements for 540 rpm (at engine speed of approximately 1890 rpm)
Normally a 6-spline shaft (optional) with a diameter of 35 mm is recommended.
The ISO norm does not limit the power of a 540-rpm 6-spline PTO shaft with a
diameter of 35 mm.
IMPORTANT: For power over 67 hp (50 kW), use a 1000-rpm output to ensure
the durability of the PTO shafts.

Normally a 21-spline shaft (optional) with a diameter of 35 mm is recommended.
Heavy use
Normally a 20-spline shaft with a diameter of 45 mm is recommended. If
necessary, a torque-limiting clutch with the maximum torque of 1000 Nm should
be used.
