John, were you letting the flap drag on the ground or held up near the frame I LET IT DRAG THE GROUND. JUST HAVE IT SCREWED INTO THE BACK OF THE DECK JUST ABOVE THE CHUTE AREA. IT'S PROBABLY 24" WIDE (ACROSS CHUTE AREA) AND 12 INCHES BACK WHICH LETS IT RIDE JUST BARELY ABOVE THE GRASS OR ON THE GRASS
I have wondered about a bellypan on mine (both) to reduce the grass caught above the frame. Both decks do it even though I blow the units off with an air hose or hand held blower.
I KEEP A 24" OR 36" AIR WAND ON MY COMPRESSORS TO BLOW BOTH OF MINE OFF, SHOULD DO IT AFTER EVERY MOPWING BUT DON'T
Tracing the hydro delivery hose (wire wrapped) looks like I need to drop the deck and pull the drive wheels to get all the caught grass out of the way. TALL GRASS CAN WRAP AROUND THE DRIVE WHEEL AND DESTROY THE SEAL WHICH COST ME $200 TO HAVE FIXED, THE SEAL WAS A COUPLE OF DOLLARS AND IT HAPPENED AGAIN TO THE SAME f3080 TO THE NEW OWNER WHO HAD BEEN CUTTING SUPER HIGH GRASS
I had to lift the seat and engine cover to clean out the ZD331 I had with a 60 in side discharge deck. It caught a lot of grass under there and in crosswinds covered the operator WHY I HATE THE SIDE DISCHARGE DECK OR ONE OF THE MAIN REASONS. I ALSO LIKE CUTTING CLOSE ON BOTH SIDE WITH REAR DISCHARGE DECK. HAVE ONE OF EACH NOW.to boot.
