MIne too . Used to have 1 guy that always did it and when it backfired when shut off I would come unglued.

With modern lubricants and better manufactured engine components it is just not necassary too cool down the engine so too speak in general. There may be certain situations that may require it but 95% of the time it will not help amything.

Leaving the throttle wide open and shutting it off is a different story. Big no no.

Turbocharged machines have to be cooled down so that the oil doesn't bake in the turbo, give the oil a minute or two to drain.

yup what has been said before. Got to give the turbo a brake after running them hard.

if the turbo is stopped without cooling a bit the oil that is there burns from the high heat and "coaks" the bearing surface.

I try to let stuff warm up and cool down, I run machines at 1/4 throttle till the motor warms up some then turn it up to operating speed. Im bad about not letting the small machines cool down but they don't have turbos either. I always throttle stuff down to idle before cutting them off.

On all the big equipment I let it run for a few minutes to cool down. I pretty much park it and by the time I sweep the floor off and get all my stuff gathered up from the cab its cooled off and ready to cut off.

now my uncle likes to switch it right off and you can just hear the turbo still whistling

I think the engines actually gain heat if u don't let them cool off. My T800 dump will do that.....temp will rise if i don't let it cool down for a couple minutes .

I understand its not necessary, but I do it just for myself. I feel like it brings down oil temps and gets that cooler oil throughout the motor so the oil lasts longer? Maybe. Probably not, but im an old guy with old habits

Cool everything down here. I have a grasshopper with a gas Kohler that backfires extremely loud if you don't cool it down.

Anyone that forgets drives that for the day to "help" there memory.

Then of course, the rest of the crew heckles the he!! Out of them for the day for causing minor heart stoppages.
