Riding Lawn Mowers

I have a YT42DXLS tractor which comes with the fabricated deck.  I ordered a much kit # 587412301 from the dealer.  The kit does NOT fit the tractor.  The bolt/knob system on the right hand (forward) side of the deck does not have enough clearance between the mower and the anti-scalp wheel to fit.  I spoke with the dealer and he said you have to disassemble (take off) the anti-scalp wheel to install the mulch kit, but  that info is not listed in the mulch kit manual.

 This is just plain STUPID design.  Husqvarna should be ashamed for putting out a part which does not fit.  Very poor design.  If I had known this about the tractor I would never had purchased it.  It is too much of a PITA to take the deck apart every time I want to use the mulch kt.
