well i'll start at the beginning & hope i don't bore anyone.i wanted a j.d. tractor 6 yrs. ago & scince i couldn't afford new back then,i was in the used market.wow! was i paying for a name or what? rusted/beat junk was going for 1700 plus! i stumbled on to a 1998 cub 2155 with the kohler & hydro trans. with 240 hrs. it looked new for $1400 kept it for another 300 hrs. & 5 yrs.great machine! but needed a something that could take a ft. end loader (fel) so i sold it for a 1998 7205 w/314 hrs. for 7k with 60" deck.i've had it for about a year now & am really getting frustrated every time i go to get a part its $50 plus! air filter $49.99 plus tax ouch!! i found a fram CAK530 for $13.00 that works fine! just a piece of foam at the end to take up the gap,but just about the same filter.engine oil filter mitsu $21.00 not again! fram TG7317 fits perfect & works great.i will switch to a napa (wix) soon though,wix makes great filters! does anyone have any suggestions on hydrostatic & hydraulic filters,them 2 just cost me $100.21 w/tax!! that hurt.i had a cub dealer in ny. sell me 2 napa gold filters(1664) this summer that were ok' til i installed the fel 2 months ago (another 3k) but now with the fel the hydrolic filter doesn't feel right , it acts like a partially plugged filter.anyone have any other suggestions or should i just stick with the factory filters at 100 bucks every 200 hours?i do have a couple other questions but will wait til' a later date,i think i've probably said enough this time! thanks in advance!
