We have a T9040 and a Seedhawk airdrill and we have trouble with the hydraulic hoses popping out when we hit a wet spot or when it pulls heavy. Sometimes a couple hoses would pop out, sometimes six would pop out. Talked to a Seedhawk rep and a mechanic and they both thought I needed to replace the hyd couplers on the tractor and new tips on the Seedhawk hoses. Tractor only has 1200 hrs, do not believe couplers are wore out, and why would six hoses all pop out at the same time? Anyone have any trouble like this or know how this can be fixed?
