Gearbox
- Mechanical with straight toothed gears; can have 5 ratios of which (4 Forward + 1 Reverse) selected by
means of a single lever for the normal version.
-Or can have 10 ratios of which (4 Forward + 1 Reverse) for both running directions, selected by means of
a lever combined with the reversing lever.

PTO
The PTO is the 16 UNI 221 standardized type with a clockwise spinning direction (normal walking tractor
version) and anticlockwise spinning direction (reversing walking tractor version).
Operation is independent or synchronized with the gearbox speeds.
Independent operation obtains an hourly speed of 675 rpm (normal walking tractor model) and an
anticlockwise speed of 985 rpm (reversing walking tractor version with frontal implements). These
speeds are obtained with an engine rate of 3000 rpm.
Synchronized PTO operation with the gearbox has a 1:5.714 synchronizing ratio between the number of
wheel revolutions and the PTO rpm.
PTO quick coupling device
This is the device that allows the implements to be coupled and uncoupled from the PTO without
the use of rods or wrenches, just with the aid of a lever that assumes two positions: ENGAGED AND
DISENGAGED.
The device is mounted around the PTO and can only be used with implements designed for this type of
coupling.
