The heat of summer

This hotter/muggier weather we have coming in is both a blessing and, well, maybe not so much of a blessing. However, one way or another, it's got me wondering; on our nice little air cooled Cub's, how much of a difference does the outside temps make in how much you use your machines? I've got 3 yards to mow and I try to kill them all in one day but it takes some time. I know our air-cooled engines aren't as efficient at cooling themselves as their water-cooled brothers but does that mean that we should shy away from using them as much/as hard during this upcoming weather with temps in the 90°'s reaching all the way up to 100°F+ and air full of humidity? I'm probably being paranoid but it never hurts to ask (you know what they say; the only stupid question is one you don't ask)! I know that air coming out the front of an M-18 powered machine can get quite warm after hours on end of heavy grass at WOT so just wanted to see what the others here have to contribute to this!

If the work needs done mine is working. Hot, cold, raining, whatever. About the only thing I'll do is take a full speed romp a few hundred yards down the street to get some air over the running gear from time to time. No clue if helps or hurts. Its as much to cool me off as it is the tractor... and it's fun.

If its super hot, I pull the side panels off of the QL. I've heard various arguments about that before and I'm not trying to start another. It's just what I do.

I also tend to change my engine oil right in the middle of super hot season (for the second time... once in the spring, once mid-season... About the time my oil is nice and black I change it (way early) and that's OK with me).

Otherwise its business as usual.

Your not going to hurt your motor. Run it with 30wt oil and forget about it. I usually try to blow out the engine with it running at idle from the front. Grass builds up from the back side. In combination with the engine running blowing forward, and compressed air blowing back, you'd be surprised how much grass is stuck in there that will come out. Keep it clean, it will be fine.

This is a good idea. I know I gotta hit the whole thing every late spring because of the neighborhood cottonwood. I'll try this method.

I use a leaf blower on my stuff after I'm done with it or if I see the temp gauge climbing on the water pumpers I'll stop, pull the screen and clean them out. Keep them clean and cool and they will run a long time.

Ditto.

It only take a few minutes at full load to bring the engine to full operating temperature. If everything is clean it will handle the heat. I usually run 10w-30 oil in mine no problem.
