I should have stayed home today. While mowing a large property and about 700 meters from my trailer I ran out of gas. I neglected to check it before I started (I always had before). After walking back to my trailer, glad I wouldn't have to carry the five-gallon can, because I have another two gallon one there as well. Gee, where is it? Oh sh**, I left it at home when I fueled up my power washer. Damn, this 5 gallon one weighs about forty- no!! It's empty too! I'm an idiot. I then recalled thinking I was going for fuel for the truck and equipment AFTER this property, 'cause it wasn't going to be a problem. Oh well, this only adds another forty minutes to a two-hour job (nearest station is fifteen minutes away). Start grinding teeth. I usually ensure I start the day with all tanks full. Note to self: this is where laziness gets you. I get gas and finish the job, and a few more. My schedule is light today, and with rain in the forecast, I decide to knock out some of tomorrow's schedule. I have a condo/housing complex that I do just the common areas. It takes me about two hours to get in and out. While mowing with my nearly new 52" Lazer HP, I start hearing a noise. Gee, that sounds like a belt delaminating. Maybe if I ignore it, it will go away... It continues. Motion control responsiveness starts to fade. "Gee, is there some correlation to the belt noise and the control?? I only have fifteen more minutes to mow here..." Well, guess what? My hydro drive belt breaks, and on a slope, thirty feet from a reservoir, facing it. Sh**! Now ask me if I have a spare. I'm an idiot. This thing only has eighty-five hours on it. Why would I expect to need a spare this early? Well, it's after 6 pm and there isn't a place open to get one now. I may as well finish the job with my walk behind. Well, while mowing along the retaining wall I notice goose droppings along the wall, but in the grass. I only mention this because I thought of it again while trimming along said wall. Did I mention that I was an idiot, and that I was shooting for the hat trick? I chose to walk on the wall, to avoid the droppings, and because I took a stupid pill this morning. Yes, even though this wall is flat, concrete, and at least twelve inches wide, I fell in the water. It was only crotch-deep and remarkably flat (considering the rest of the area was lined with rock, which would have twisted my ankle, causing me to fall completely in and drowning my FS85 Stihl), so the trimmer stayed dry. I got right out and looked for witnesses. I didn't see any and then start laughing. Lastly, I can't leave the Lazer HP where it is. If someone wants to be funny, or touches the parking break, it will roll down the slope and probably into the lake (over the same retaining wall I fell off). I have to move this thin by myself. All I had to do was turn it and move ten feet, where the slope went the other direction and towards a flat area. While grabbing the front strut with one hand to turn it, and rolling the tire with the other, I was able to get it where I wanted. However, it was during this procedure that I found out why I seemed to keep smelling dog poop. It seems I ran some over and it was smooshed in the tire tread that I had just pushed my hand on. Yes, there was now a waffle-like pattern of dog droppings on my hand. Great. I'm done. It's time to go home. Tomorrow will be a better day. By the way, I haven't changed belts on this type before. What is the easiest way to do it, at a mobile location? Has anyone else had a belt fail this early?
