I've read everything here and over on www.heavyequipmentforums.com on the ASV system on CAT's MTL machines, just how bad are they? From what I've read, 50% say bad, reasons; too much up keep and cost of replacing tracks, avoid rocks and sharp objects blah, blah blah. The other 50% say they are the best for smooth riding and low ground pressure and operator comfort. This is the way I see it, I have gone through a set of OEM tracks on my T190 at 970 hrs, one side was so worn out that it snapped, cost of replacement was $3800 CAD to replace, since I had already bought and paid off the tracks 1 month prior, it was easy to do. I charge $5 extra an hour due to the CTL's ability to take extra work not usually meant for and smaller machine, but when we're in a pinch, anything that has tracks will suffice. I never abused my tracks and any cuts in my second pair were from minor mishaps when a rock strayed into my path as it fell out of my bucket on one of my many long hauls over floors and driveways. I am by no means a weekend warrior on these machines and I don't have the mentality of "oh, it can take it, it's built like a f***ing tank....." and just go off into the unknown and do some serious damage. My line of work that I take has shifted from 75% demolition work to around 25% demo and the rest is clean up and general excavation. I always keep a garden hose nearby in the wet season to wash the junk and mud that builds up in my T190's undercarriage and I never run over coarse rock with out smoothing it out first and if I do excessive turning on pavement, I dribble some sand or dirt down to decrease the friction. Upon getting a demo CAT MTL this coming week (assuming they have one, and they trust me) the first place I'm taking it will be the pre-load we are doing now, 3" minus gravel, blasted and crushed in a quarry, sharp rock, but soft and brittle under pressure, I want to see what happens when it gets between the track and rollers, then the mud, where it builds up and how long it takes before it starts to slow the machine down. If I struck up a deal, I'd be buying a used 247 or 257, the few hours I rack up in a week doesn't justify buying new anymore. So is it worth it?
