I don't dislike the left foot brake on my John Deere 2305, I HATE it. .........QUOTE]
Someday you will find a task where individual brakes are needed, and using them with the left foot is not a big feat to learn.

In the meantime, just ignore them as you don't need them.
Actually I will never have occasion to use split brakes. When I was farming, I used split brakes to turn with, but I quit farming a long time ago. I haven't used split brakes in the last twenty years and don't think I will make it twenty more.
I just think the benefit of split brakes are something most operators never need.
I don't have much use of my left leg, so I am used to using my right for clutching and such though I am at a severe disadvantage in a butt kicking contest:laughing:
