I have an X series on order. It's coming with the K46 Transmission. I've read some information in the forums that leave me concerned that it may not be the best option for me.

I'm a heavy man (ok, I'm fat but working it :bbq: ). I have a .41 acre yard that is essentially one 8 degree sloped hill. Mowing pattern would be up and down hill with each pass.
I will mow weekly. Probably about 38 weeks/yr.

I need the 42" deck for the openings I have to navigate.

For $200 over the price of an X354 (w/ all wheel steer and the K46) I could get an X370 w/ power steering and the K57). That's about my budget. I pre-ordered the X354 because 4 wheel steering seems more useful based on the back and forth mowing and associated turning but would I be better off with wider/easier turns and the K57 transmission from a longevity/durability standpoint. I want this tractor to last a LONG time and plan to take good care of it.

Thank you in advance for your advice.

I'd definitely recommend getting the X370 for all the reasons that you stated. I think that the 2 wheel steer tractor would be more stable on hills. The heavier duty transmission will definitely last longer. Especially when carrying a heavy load on hills. The power steering and deck lift is something that you didn't realize that you needed until you use it. lol Since I have used both on my X540 I'd never go back. The power lift is really helpful when using the 48" snow plow.
Plus it's only a small price difference over the X354.
Good luck

As mentioned, the K46 gets a bad rap, and it isn't that deserving of it. I have a 2002 LT150 that has the K46 in it, and it's still going strong. Main thing is to keep the cooling fins clean and the transmission cool. Heat and friction build up will kill any hydro transmission, and not just the K46.

I had a L108 for about 9 years. The only thing major was blown head gasket. It was used pretty hard for the last 7 years. Plowed a 60 unit trailer park many times with it. Also cut acres of overgrown grass.

That being said would I buy a tractor with a better transmission? Yes

Also can't say enough about having power steering and implement lift. With PS you won't miss all wheel steer.
