Genuine Tuff Torq Part # 7A646084181 Fits Specific Tuff Torq Models That Require This Part # Genuine OEM Tuff Torq Part Review: Good fit for my Husqvarna - Works great, fit my mower (Husqvarna YTH24V48) without any issues. Review: Appears to be fully functional OEM unit. - Purchased this to replace Tuff Torq transmission/axle on my 14 year old Husqvarna riding mower. Was packed in Tuff Torq marked box, and padded very, very well. Arrived in good condition, but the box was oil stained on one end. There was oil - not a lot - inside the box and on the transmission. I'm naively assuming the oil was a result of the box being stood upright during shipping/handling and it leaked out from along the shaft as it didn't appear the sealed filling port or vent port leaked. Hopefully that is not a bad assumption. We'll see. Outwardly, was exact match for old one and fit/aligned perfect. installed in about 1 hour. Had wrongly assumed it would have the feather/shaft keys for the rims, but it did not and nothing in seller's information suggested it should. Just my bad assumption. I've mowed with it 3 times now, about 2 hours each time and work as the Tuff Torq transaxle it replaced. A section of ground I mow is on a 30 degree incline, steeper than the transmission is likely designed to properly handle. When combined with a tight turn or thick grass, it causes the mower to stop moving with pedal fully depressed. A quick 'pump' of the pedal reengages and restores forward movement. That happened with previous Tuff Torq transmission though I recall it not happening until 8-10 into owning/mowing with it. Makes me question my assumption on the oil I observed in the packaging. ## Features - Brand New Genuine Tuff Torq 7A646084181 Hydrostatic Transaxle K46BT OEM... - Genuine Tuff Torq Part # 7A646084181 - Fits Specific Tuff Torq Models That Require This Part # - Genuine OEM Tuff Torq Part ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #475,248 in Automotive ( See Top 100 in Automotive ) #704 in Automotive Replacement Transmission Hard Parts | | Customer Reviews | 4.2 out of 5 stars 19 Reviews | ## Images ![Tuff Torq Genuine 7A646084181 Hydrostatic Transaxle K46BT OEM - Image 1](https://m.media-amazon.com/images/I/5191j3VhDQL.jpg) ![Tuff Torq Genuine 7A646084181 Hydrostatic Transaxle K46BT OEM - Image 2](https://m.media-amazon.com/images/I/41c6DqnhLbL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good fit for my Husqvarna *by D***J on January 10, 2026* Works great, fit my mower (Husqvarna YTH24V48) without any issues. ### ⭐⭐⭐⭐ Appears to be fully functional OEM unit. *by L***R on August 14, 2024* Purchased this to replace Tuff Torq transmission/axle on my 14 year old Husqvarna riding mower.
