Dixon ZTR 4518K (2003) Engine Identification

[dww1963]

Can anyone help me identify this Kohler Command Pro 18hp Engine on my Dixon ZTR 4518k Zero Turn. The ID tag is so old it's basically crumbled to nothing. I need to buy a few parts for it and want to make sure I get the right parts. A link to a parts diagram would be awesome too.
Also, would anyone have a line as to where I can get new deck spindle hub for the 50" deck part number
HUB W/ZERK KIT 539115416 ? Surely someplace has one of these.

Husqvarna kept one of the Dixon model lines in production and discontinued all of the others .
Dixon parts that are not a current Husqvarna are very hard to come by .
You may need to replace it with a spindle from some thing else .
If you do , be careful that what ever you replace it with has a blade that is the same length
I got caught out after spending ages replacing the spindle housings on a local mower only to find I now have to buy longer blades & cut 1/2 of each of then and rebalance .
