Here are a few lessons I learned from the heat. First, I'm not as tough as I thought I was. I use a Gatorade cooler for my drinking liquids. I fill it with ice and whatever water will fit. I take a second gallon in case I run out, which has happened. I have a smaller cooler that I put frozen gallons of water to use as ice, then I put water and "bar mops" in to keep cold. Wal-Mart has packs of these "bar mops" (really large hand towels) for 5 bucks. I take more frequent breaks and take the Gatorade cooler and the bar mop cooler into a shady spot. I squeeze a bar mop until it won't drip and wrap it around my neck. My head and face are cooled off and stopped sweating in 5 minutes. This refreshes me more than anything I've ever tried. Equipment: Don't fill fuel in any equipment as far as usual because expansion will be greater when it's really hot. I realized this when my trimmer was acting starved and the fuel cap would pop off. Also, oil works harder in air cooled machines so change it before it gets really hot and consider an oil conditioner like Lucas. I know it's going to get hot like this again and again. I'm already thinking about a light kit that can be quick attached for times when I need to mow in the dark. Movement: Any movement is taxing when it's extremely hot. Think about your movements. For example, I took the Jungle Wheels off for a yard I like to stripe perfectly. I was doing great until then. I felt like I'd been whipped after that yard. Also, keep everything in place and try not to have to keep moving something for no reason on the trailer. I'm sure you guys have tons of stuff to add and I'm interested in hearing them.
