Hi, my BX2200 is 20+ years old. I bought it the first year they came out. A few years back I replaced all the flex lines. To the steering, the bucket and such. This year I was pushing snow with my grader blade on the back and I lost all my hydraulic fluid out the back. Due to the temperatures and such I have not got out to examine what blew but I was hoping for some insight from this group. I have had the filter go and am familiar with that mess. This is farther back by the 3 point hitch area. Any ideas? I would like to buy the o-rings and seals it takes to repair this, I'm just wondering what might be the "go to" seal kit to start with.
