O.K.,
I'll add my 2 cents to this discussion-I am a Dealer (a top five Dealer in the Country for Skid Steers for my Brand), and I rent a lot of Equipment (both the Brands that I represent and others)-
I think Cat has done a great job with the Controls (Joystick, low effort), and they were on the front end of entering the Tracked Market (compared to say, Case New Holland or Deere).
I have had both a 257 and a 257B in my Rental Fleet, and, in my parts of the Country where we have a LOT of Rocks, we went through more Tracks than we should have-the rubber Bogie Wheels get eaten in minus Rock, and we have torn the drive lugs out of 3 sets of Tracks-the problem is, according to the Track Suppliers we have dealt with, that they are an OEM product only-the best price I could find was $1750 per side.
My Manufacturer was quick to point out that the Cat Rental Stores have for the most part gone away from renting the Track Machines, instead they are putting the Loegering Track Systems on their wheeled machines and renting them in that configuration.
We have sold some Loegering Systems and as far as I'm concerned, the jury is still out-Loegering is offering Dealers and extended Warranty on the Drive System of the Machine, which makes me wonder why? If you think about the Chain Drive system on most wheeled machines, and the forces applied by the Loegering System, there may be a root reason.
My Manufacturer says to advise Customers' that (as a rule of Thumb) Tires will cost you about a $1 per Hour to run, Tracks will cost you about $3 Dollars and hour to run, so if you are buying this for a business, you had better be able to recover your investment.
We have a lot of Mountains here, and the Track Machines do well in those conditions, and in Snow they are a treat, but get it on Ice and it's a wounded Duck.
My take on the best Tracked Machine out there? I would say as far as the Track design (which is manufactured by Burco for all three units) would be the Case, Deere or New Holland (that is in alphabetical order)-lots of reasons why (and I think the ASV IDEA is good,it just has a History of continual problems). The Case and the New Holland design are identical, the Deere's is different-
