Allow me to chime in with a few comments of my own. For all of you out there considering a tacked machine to do anything in business with, you need to do your homework as everyone else has correctly stated. Having done much of this already, I can easily help you narrow down your choices in tracked machines. This is my opinion of course but I do work in the field and have access to more info than many private individuals. If you are considering any machine with less than 5 years of experience in the tracked machine market, you are throwing your money away. The machines that have just hit the market are new, untested and unknown. New Holland, John Deere, etc. They've rushed a machine to market because the tracked machine market is hot right now. Gehl and Mustang didn't even bother to develop their own machine; they buy from Takeuchi and paint the machines yellow. The Cat machines use the ASV undercarriage and the ASV machines are ag machines. They don't survive in construction environments. Putting plastic and rubber components in an environment with rocks and abrasive materials simply doesn't make sense. In fact, Cat will not honor warranty issues if the machine has been run in gravel or sand. Don't believe me? Ask your salesman for a copy of the undercarriage warranty disclaimer. And then ask him what it will cost to rebuild that undercarriage in 1200 hours because the tracks keep coming off on hillsides. Or, just ask how much a new set of tracks will cost. You'll not like the response.
I'll admit right now that I am Bobcat-biased. That is a big reason I am typing this. I see a lot of inaccuracies in the comments and wanted to set them straight. If you have not tried a "K" series Bobcat, you're not comparing the best machine on the market to the other brands. Bobcat has been working on the tracked machine concept since the late 90's and has made numerous advances over the machines of old. There is only one other company with more time in the tracked machine market and that is Takeuchi. Ever try to get a Takeuchi serviced? Ever try to even find a Takeuchi dealer? They aren't on every street corner Gehl and Mustang suffer from the same issues. They're a Takeuchi once-removed! I used to rep Takeuchis and I in fact loved the machines but their after-the-sale support sucks. Take into account the status of their machines. No High-Flow? That's a little behind the times don't you think? You're going to spend $50,000 plus on a new machine and then spend even more money to send it to a third party for a High-Flow enhancement? At what cost and now who's going to service your machine? As for some of the other brands who offer big iron as well, who do you think gets the attention in the shop? You with your $75,000 combo or the guy with the $300,000 excavator next to you?
When I hear that Bobcats "aren't made like they used to be" it makes me wonder why the comment was made. Either they haven't been in a new machine or they are going off a bad experience they've had. Fact is, Bobcats AREN'T made like they used to be and that is a good thing. In fact, I'd find you hard-pressed to find a tracked machine out there right now that will work with a new T300 and a Fecon Bullhog mulcher. The machines are putting out more flow than ever before at 37 GPM and 3300 psi, (and the High Flow option is about $1,600, NOT $10,000 like someone said here...) and the cooling systems are vastly improved, due mainly to newer, higher demand attachments like the Fecon. Also, and I'll guarantee that NO ONE here knows this. Mulchers need to be calibrated to the machine they are being run on. That is, you may run a head on Unit X and have it perform great and then put it on a BIGGER machine and have it perform poorly. There is a process for adjusting the attachement to achieve the best performance on a specific machine. It's not possible to have a "fits all" unit. Keep in mind that even the small attachments are some $20,000 in many cases and the machines to run these are over $50,000. Most dealers out there won't have a clue how to set these machines up. Bobcat has now introduced the Forestry cutter attachment which, unlike all other manufacturers in the market, is an attachment designed around the Bobcat machine. Taking the Fecon unit and tweaking it to their own needs, they've produced a unit that will do all the clearing/mulching jobs and do it better. The skid loader itself gets numerous changes to run this piece, including shrouds, guards, cooling package upgrades and the like. And best of all, if you do have issues, you'll be able to speak to your dealer, not a third party supplier like every other brand.
By all means do your homework. Obviously you all have internet access so get online and research this stuff. The more you know the better off you'll be.
