evening: just thinking quickly, if oil was coming out of the dipstick...on the 400's this is a screwed in type of unit on the tank top...if oil was coming out there, it sounds like the threads could be stripped? to strip them it would take pressure inside the tank and the dipstick being the weakest link..the oil comes out, better than having the tank expanded/burst. It sounds to me that to keep the load up[ homeward bound] the raise lever was held up continually when it was trying to auto kick out as the cylinder limit was reached. that would of put pressure on the system components[ dead headed], and possibly/has damaged the auto kick off/spool valve operation internals of the valve body/internals in general? That comes back to removing the valve body and checked for a stuck bypass safety/spool damage/kick out operation, bent or stuck spool, broken spool spring. retainer clips, etc. a long shot is maybe a piece of plastic that was a temp fitting covering/filler was not removed when the cylinder or lines were being worked on? Also assuming that any lines remover earlier are back in their correct locations Try contacting " Belarus.ca" for a hyd piping schematic, if you don't have a dealer you can contact? i can check my 400 book and trace the lines, being they are very close machine, but may differ for sure. hope it helps

Well, when our family moved to our 20 acre site near New Prague, Minnesota, I had one thought in mind. You guessed it, farm it somehow. A little history is in order. In my younger days, mom, dad and my brother made frequent visits to dad's youngest brother Pete, who took over the home farm from grandpa MIke. It was the typical set-up, milk cows, pigs & chickens. In the winter, we'd play
