Is the horsepower rated differently because of gross or Net???
Either way, when I was selling the "Orange version" the CK 20 Hydro was the worst one. The little boxy, and now very unfortunatley discontinued LB1914,, was a superior tractor in every aspect, except in the ease of getting off & on ( it was a little tight and a very utility in design).
I found the CK 20 H was a complete disappointment in over all value simply because it was a complete gutless wonder and performed inadequately for most of my clients. Generally pulling a 42 inch light duty brush mower up various grades and hills. The CK 20 gear was a little better. They are great in concept, but in my opinion even producing a brochure to present to prospective buyers is just a celebration of something somewhat what less then tractor mediocrity.
On the Up side,,, Maybe Bobcat (Ingersol Rand) will teach big orange brother how to adequately stock parts, treat their customers with the consideration that they might have an IQ some what higher then a house plant, and invoice the tractors in a way that doesn't leave a dealer baffled at the complete lack of organization,P-O'd at stupid and pointless redundancies and total lack of co-operation in problem resolution for customers and dealers alike.
For myself I would not buy a CK 20,with either name on it... But the 25's & 30's really are a super good product for the average home owner (WAY better then MANY other bigger names on the market, especially for the money) The gear models are darn near bullet proof... But, I'd actually consider paying more for the BobCat name simply because odds are,, I'd get parts when and where I need them with no excuses or mistakes. And someone at thier parts counter could probably explain how to install a techincal part. Very few of the Orange dealers live long enough to learn how to install and repair things on the tractors. I've been with them since the sister days of the other orange tractor,,, But still, having that time experience and history counts and makes a owners life more pleasant because us oldies can diagnose problems so much faster, often based simply on having listen to, seen, or fixed one like it before.
But if you can find a "orange" dealer that has survived 5 years, odds are they'll stay around. It seems much of their survival is location oriented.??? (much having to do with their regional Rep)
