RKO.... you have been around here awhile, and I know you are an intelligent guy, but that last post to be honest was not up to your usual standards. Your point of being in mud so soft I'm going to sink down to the belly pan is pointless. With material that soft.. what are you doing with it? Are you loading it out? Because at that point any truck is going to sink as well. Are you packing it? I think not. Your rifling it over right? Ahhh in that case, I can just push it up with the track loader into a pile. I have done it before....I have also buried a 973C to the belly pan. Why? Someone said it was too soft but there wasn't a hoe around so... I did my best.
Once again you missed the boat on what a track loader will do. Why do you insist on digging a trench with a track loader? Each machine has a purpose, bulldozers generally don't load trucks, excavators don't generally push dirt up, or spread.. yada yada. Wheel Loaders don't scrape up 32yds of dirt and carry it 1000ft to the fill and spread it. Grader's don't get loaded by an excavator and carry dirt to a fill. So why insist on comparing a track loader to an excavator for digging a trench?
Ok... Backfill now your in my ball park. So your saying using a track loader to backfill sewer and water ditch moves too much dirt and wastes money? Hmmm well thats exactly what I do. If you've watched the videos or seen the countless thousands of photo's I have posted here then you'd see that. Yes a track loader will move a lot of dirt to backfill a small trench, but it does it in a hurry. A track loader and vibratory compactor can do a lot of work in a day, what else are you going to do it with? a Hoe and a hoe pack? Well yeah one machine potentially costs less to run, but how uniform is your compaction? What happens when your running multiple lines in with services and you don't have uniform compaction? Your road settles.
I am not saying the track loader is the be all end all of heavy equipment. It has a purpose, as does an excavator, tractor backhoe, wheel loader, scraper, grader, scrader, rock truck and packer.
The CTL subject, CTL's have a time and place. Landscaping is one of their niche's. a CTL is a great machine, very useful. But the largest cat CTL would still be destroyed by a decent track loader when it comes to digging into a hard bank, pushing up a pile... or pushing in general. Ever loaded a truck with a CTL? Man those boards look awful high don't they?
It comes down to the operator. I like to think I am pretty good on a track loader. I was a hoe operator first, I was hesitant to ever jump in a TL but I did it and I am glad I did. They are a machine that is under appreciated as Scott said. They chew up undercarriages yes, but they can do some serious work if you let them.
Baz also made a great point... "If I only had one machine". Yeah the excavator would be your machine. Why? It's versatile. You can dig a trench, basement, cellar, you can grade, strip land, load trucks, knock down trees, pull out concrete. You can do all that. A track loader can do all those things as well... maybe not as efficiently at some of them. If you really wanted to do all that with more efficiency hell buy yourself a backhoe.
