    Do you let your equipment warm up and cool down?

    I let it warm up a minute at idle before the first yard of the day. After every yard I load up and let it idle while I raise the gate and strap it down, lot of time they will backfire if you don't let them idle for a minute after running WOT.

    My 2 strokes: I try to go easy on them upon cold start up and let idle down after hard use. I use Opti-2 oil.

    On 4 strokes far less concerned about shut down hot spots. Upon initial start up yes I go easy on them when cold most of the time. For example Toro Timemaster goes right to.full throttle upon.start.up. I use synthetic oil multi grade. Castrol syntec 0w-30 on that unit since it's stout oil flows.quickly. And has a cult cars. Also use this exclusively in my 4 stroke snow.throwers.

    Oil will.always lube.up parts.better.when.warm and flowing.

    I let my equipment idle for a minute or two at the beginning of the day, and then after running they idle for another minute or two. Just like TNGrassCutter

    Usually, the first job of the day, I will crank up a mower and take it to the back of the yard at a moderate power setting without blades engaged. By the time I get to where I want to start mowing, it's warmed up enough to take a load properly. I also usually let my equipment idle for a minute prior to shutting down, which means driving it on the trailer and raising the gate while it idles, so no time wasted.

    I let my big mowers (Kawi engines) idle for a couple of minutes before the first cut of the day or if they've been sitting for a while and have cooled off. My Honda 21 incher needs to be warmed up a good while before I can engage the blades or it will stall out, but it has the double blade system on it. I only idle them down if I've been working them hard and/or it's really hot out. Otherwise I just shut them off at idle.

    For the 2 strokes I just fire them up and use them as soon as they will come to full speed and have good throttle response, which varies depending on the particular piece of Shindaiwa handhelds and my Husqvarna trimmers are pretty much ready to work as soon as I start them. I just turn them off when I'm done with them.

    The colder it gets, the longer I let my equipment warm up before use. Cold oil combined with a cold engine is a killer. I read a report on tractor trailers that use engine oil preheaters. They said they could get something like 40% more life out of an engine if the oil is preheated.

    What I really don't like doing is moving my ZTR with ice cold hydros. I may put a preheater pad on the tank to at least warm up the oil. It's a 1.5 gallon steel tank so a pad should work fine.
