I have a 1988 B2400 that I'm going to sell. The main problem is that it's overheating. It is most likely the head gasket or cracked block. Obviously a big difference in problems but I'm done diagnosing. The throttle linkage is also broke and it's stuck on full throttle. It starts, runs and all hydraulics work. It's 4wd with a FEL. Also has a 5' back blade and 60" belly mower. What's a good opening asking point?
