Replacement tractor

I have the small Kubota 18hp 4x4 with the bucket and mower. Its perfect for a small wooded yard like mine. 4 acres.

Its light, and most importantly doesn't have enough power to bend or brake anything.
I've used New Hollands in the 35 to 80hp range and they were tough as well. Also a grey market Branson 35Hp. The Branson was a beast and without a doubt the best bang for the money.
