The upper one of these two indicators placed on the tractor
indicator shows the engine operating hours. And the lower
one shows the PTO speed. PTO speed is 540 and 750 rpm
as standard.
Warning: Warning symbols on the instrument panel indicate
the warnings and operating conditions of the systems
operating on your tractor. PTO speed cannot be read in digital
screen in some of our models. Ratio of PTO speed to engine
speed is indicated in green and red on the indicator scale.
Moving of the indicators when the ignition is switched off is
caused by step engine feature and this is normal.
