I picked up a used Bush Hog FH188 flail. Upon getting it greased and oil changed I started it up and noticed some “clanging” in the mower. I ran it for a few passes and then looked under it, I noticed that it looks like the blades are hitting the deck right at the front edge in an even pattern all the way across. The rotor looks straight but I have not tried your string trick.
I’m guessing it could be the wrong blades were installed at some point? They are scoop type, but don’t look exactly like the ones for this model. When I pull one of the blades outward from the rotor to the deck housing it may have enough clearance to slide a business card between the blade and housing.
Any ideas?
You can see the rear of my $100 Ford 917. I was getting knife strikes on the back & torched out the bent bits. Welded some patches over the holes.
Previous owner removed knives, presumably due to hitting the hood. At first I thought it was some previous patches welded inside, but it turned out to be a tweaked hood. Lasted for a few years then got retired. Under $500 in it total with repairs for 4ish years of light commercial usage. Was a decent deal. Still ran fine last time I parked it.
