The 4-speed LT95 transmission has two PTO units fitted.
The trailer-drive PTO replaces the gearbox mainshaft
output bearing and its carrier.
An additional PTO for a hydraulic winch can be seen below the trailer drive.
The standard military winch for a Land Rover 101 is the
Nokken
mechanical winch, but this
prototype 101
has been fitted with an alternative at some time
in its long career.
Although it shares the same axis as the main gearbox output shaft,
the trailer PTO is instead driven by the (constant mesh) low-speed cog
on the transfer case intermediate shaft.
In this way it revolves at same speed as the 4x4's propeller
shafts in both low-ratio and high-ratio.
Note the safety hoop fitted around each rear propeller shaft.
Its purpose is to catch the propeller shaft
if its front universal joint fails.
Without a safety hoop, the shaft could then dig into the ground
and "pole vault" the rear of the vehicle into the air
or sideways - possibly fatal in either case.
At any rate the shaft would be badly damaged without them.
Does your truck have similar fittings?
