I picked up a like new 52" mower deck model 78370 today for a very low price. I have a 518H tractor repowered with a P220G engine. I am hoping that there would be a way to mount the 52" deck on my 518H. My existing 48" deck works well but is rusting out. I do have all of the mounting hardware that I could transfer from the 48" deck. Previous owner tried to use the deck on a 312-8, but his AG tires were rubbing against the height adjuster rod in back, and 12 HP was not enough to drive the deck properly. Thanks for any help.
