older l775 I want to flush out the systems. Specs call for 90 wt in the gearcase and chaincase and Only Dextron II ATF in the hydraulic reservoir. It has been sitting and I would like to run it with "cheaper" oil/fluid for a week/month or 2, then change fluid again. I am wondering if I can use "303 tractor fluid" or equivalent ($40-50/ 5 gallon) in the hydraulic system instead of ATF? The bobcat dealer also says if I want to rent their auger attachment, I have to use hydraulic fluid not atf. Would it be detrimental to run the "tractor fluid" long term? How about the same tractor fluid in the chaincases? any possible damage to seals etc? Thanks in advance!
