Our comapny owns two skid steer loaders 1 is a Cat 226 which has done 1900 hours and the other is a mustang 2054 which has onlydone 720 hours. we are encountering hydraulic issues with the mustang first the raise and hall would stick and go all the way to the top on its own, then the aux started sticking the the crowd control was next to go. The dealer cleaned out the control bank and now we have no Auxillary when you put into floating, which is real hand especially when trying to use a landscape rake or sweeper! so the dealer swaped the control bank for a new one! now we still have no Auxillary when in float mode and the float detent is not there any more! The Cat has not missed a beat since they day it was bought! Has any one else encountered these problems?
