I grew up on a small dairy farm, driving old tractors, primarily, a Farmall H, a Farmall A, and a W-6. Like some of the others here, I learned to use steering brakes back then.
My JD 4600 HST has 3 brake pedals. On the left are the two individual brakes. On the right, up a little higher than the HST pedals, is a brake pedal that is linked to both rear wheels. This is also the pedal that you use when you set or release the parking brake. This is a great setup!:thumbsup: I think John Deere has that part figured out very well.
I've nothing really against Kubotas, but I'm glad I don't have to do the "Kubota shuffle" to use my wheel brakes. I also don't have to mess with latching and unlatching a connector between two brake pedals
My current tractor is a dream to drive compared to the old iron that I used as a kid. I go on some wet, rough ground on my property, so I do use wheel brakes at times. I also use them in my snow removal. They really help to bring the tractor around when you need to.
With HST, I almost never need to use brakes for stopping. I almost always set the parking brake when using the backhoe, and I set it when I am parking on any amount of slope.
