Farmer Helper Hydraulic Boom with 4′ Sickle Brush Mower, 3 Point FH-BRM120 Requires a Tractor. Not a standalone Unit.

No assembly instructions, factory connected cutter head to wrong valve, boom up/down connected to maintained valve, which is supposed to be for the cutter head. Finally found manufacturer assembly instructions on YouTube, but not a very good video. You better be mechanically inclined, or be prepared to shell out big bucks for a dealer to assemble.After using it a while (about 15 minutes at a time) Found the plastic locking nuts do not stay on. Had to drill and install cotter pins. After about three hours use, hydraulic motor locks up after a few rounds. Will have to disassemble and locate that problem.
