Moat of the machines out there today are much more comfortable than the ones of 15 or more years ago. I have a Cat 246 that I bought somewhere around 2005 with 70 hours on it ( basically new ) Cat makes strong, reliable work ready equipment. Easy to service and parts when needed are easy to access and not overly expensive. Mine has a no def no egr Perkins diesel.. it’s really strong for a machine of its size. I ended up putting a full set of Logering tracks on it and doing away with the tires.. it’s a night and day difference in capability.. I would never go back to tires.
Cat, Kubota, Bobcat, Deere , and others are all nice and as long as they are well maintained, should last thousands of hours. Currently mine has 750 or so hours on it.. only basic maintenance has been needed like oil changes and filters. I do it every 2 years because I don’t put many hours on it.
