Great info Mr Pavel.
The H/L T90 I have and the T72 both have the on/off switch on the rear plate, really constricted with log and fuel drums fitted!
I use a screwdriver to operate it.
Next time I will relocate the switch
Just also be careful driving up a steep incline as the barrels and log can get caught on the ground. Better to take inclines at an angle. Just from my own experience of ripping the barrels off going up hill.
