Mower decks interchangeable

I have a pualan pro pxt16542 tractor. Prices for bearings are $16 apiece didnt bother asking about spindle. My question is can i buy a husquvania( same company) deck or are they all the same what brands fit pualan pro. Found asnow thrawer model#9607450 will it fit. Dont know alot about them

Yes,
If it is from the same year they should fit however there are a few different decks that were common across the entire factory output.
The bottom end did not have a cross stabilizer bar at the rear.
Then there are several spindles , long & short 3 bolt and long & short 4 bolt.
