Tractor Supply sells this adapter. I had a X485 and went with the rear suit case weights. Didn't think the rear tires held that much but I forget the amount. Also, mounted rubber strap type tire chains when snow blower was attached to avoid damaging the driveway. Worked very well.With one of these adapter and a garden hose. I filled several rear tires before I was reincarnated as an old cogger
How do I put liquid in my back tires on my x475 for traction.
