They make the transmissions for most mowers. Buy the mower with the best engine/transmission combo you can afford.
I bought the X350 this time with a Kawasaki engine that’s smooth...my last mower was a 12 or 13 year old Hustler ZTR with a Honda engine. Hustler cannot no longer get the drive axles for the mower I had. It was a GREAT mower considering I paid a grand used. The new tractor has serviceable spindles. Buying one that was serviceable was important to me. In the Deere line you’ll have to step up to the X370 for a serviceable transmission.
