Do you "cool down" your equipment?

    Hey guys, i have a 25 year old guy working for me this year, running my Kobelco sr35, Taki TL130 and a 650J.....he NEVER lets stuff cool down just stops and turns of the key with no cool down time at all....sometimes I start a piece, and the throttle is still wide open. He has been operating for about 6 years, and is amazing in the TL 130 and the dozer, but this bugs the he** out of me. I have always been taught to let the equipment cool down for a few minutes before shutting it off. Especially with turbo charged equipment.
    I always give my iron time to warm up and cool down....

    Indont so the cool down but at a minimum you need to drop the throttle

    Shutting it off with it throttled up is a big pet peeve of mine... I've never thought about the cooling down part tho..

    I do the same as you even in the summer months I try to let them warm up . I even let my gas stuff cool a little before a shut it down.

    I let everything cool down and expect anyone using my equipment to do the same.

    I shut the throttle down for a few seconds and shut it off....My thought on cool down, idling it, the fan is not running as fast, so its not going to cool it down anyways

    I was taught that diesel engines need to run at idle, or just above idle for a couple bugs me when stuf doesn't get warmed up and cooled down properly. But, I have heard that the new tier 4 iron doesn't require much cool down, something to do with the new emisions and DPF.

    I don't think gas engines matter that much, it can't hurt, but Diesel engines really do benefit from some cool down time.

    naturally aspirated engines can be shut off at higher rpm without much negative consequences. It's the turbo that needs proper cool down for longevity sake.

    In short yes... especially on turbo or if I've been working the machine real hard. A few minutes to equalize the temps will help engine life..
