Price was right so I bought it.. Now trying to figure out some things--#1 dual hyd lift levers..Per book the inner one(closest to seat) is suppose to lift and lower the implement---Inner one seems to do nothing --the outer one lifts and lowers the implement--reckon something is plumbed backwards???If I understand it right, the outer one is suppose to work external cylinder such as the one on the heavy box blade I got with the tractor.....Going down the road to bring it home, it would constantly lower itself about 10" then raise back up...any enlightenment on the two levers and the lowering and raiosing on its own?????? Also, what is the deal with the D, M, P lever down by the hyd lift levers? It is currently set on "P". and will not move.I simply want to use a bush hog behind it right now...Any enlightenment on this?? Thanks
