Is this the belt that drives the front cutting deck and is fitted between the front twin pulley and the single pulley on the top of the cutting deck of a Husqvarna PR17 AWD?

I am afraid it does depend on the size of the cutting deck, please see below options for the belts: 94cm Cutting Deck - 589 53 85 01 - Belt - https://www.lsengineers.co.uk/belt-genuine-husqvarna-part-589-53-85-01.html 103cm Cutting Deck - 589 53 44 01 - Belt - https://www.lsengineers.co.uk/catalog/product/view/id/151495 112cm Cutting Deck - 593 80 64 01 - Belt - https://www.lsengineers.co.uk/catalog/product/view/id/337351
