Hey there, well heres my opinion,,, ive worked at cat for few yrs an ive seen the good the bad an the ugggglyyy, I guess the best thing to say bout the cat is that it looks good,,,, but the kicker is they have been known for there motor issues here an there,, really no matter what the make of the cat skid steer, there all power by the caterpirkins,, witch basicly is a small perkins motor with a cat logo on it,,, but there known to be expensive when dealing with motor repairs, plus hard to find used replacement motors laying around, but it is possible to fix tho,, but with the case 1845 s them thing are built like tanks,,, hyds an motors can take a heck of a beating,, the motors are 4bt Cummings an are actually lil bigger hp wise over the lil 236 fella, no to mention ya can find the 4bt cummins parts any an everywere, an they are easily found any an everywere, ya just don't wanta runnem hot too many times due to theres no liners in the block , but theres room for boreing the block tho, but over all the 1845 is a pretty tuff machine weather its 10 or 20 yrs old,,,they hold there reliability.
