About the Husqvarna YTH 20F42T

The Husqvarna YTH 20F42T is a 20HP, 42-inch hydrostatic riding mower built on Husqvarna's proven mid-range platform. It uses the Tuff Torq K46 series transaxle — one of the most widely used hydrostatic transmissions in residential lawn tractors — which means parts from this machine cross over to a broad range of brands and models.

The standout listing from this machine is the complete Tuff Torq K46BT hydrostatic transaxle (part number 7A646084180 / 404047). This is a high-demand part that commonly fails on hydrostatic mowers and is expensive new — finding a good used unit at a fraction of new cost is a significant savings for many mower owners.

All purchases go through eBay's secure checkout with full Money Back Guarantee. Parts are honestly described and photographed before listing.
