[2005~] I drove a dumper that look like the ones shown below in photos. It connected me to various works. Some are like, puddle filling, aggregate transportation, Moving 'river sands' and so on.
However since these dumpers were manufactured around 1986, it had severe problems that could have popped up like, Sudden Stop of the Engine Throttle, Defective Fuel Pump, Failure of Oil Pressure Gauge. etc
Especially, works like moving 'river sands', caused frequent malfunction of a retainer from the drive shaft.
Luckily It was not a serious problem for me; thanks to my experience as a mechanic.^^
I was not nervous even when such problems occurred. On the contrary, I was natural in keeping myself in peace.
