I've said this several times and it's fitting here.
The most complex thing to understand here on TBN is the broad variation in uses of tractors. Necessity dictates operational methods. And dictates the steepness of the learning curve.
James uses his tractor on steep terrain a lot. So do I.
James' HST tractor has the brake pedals on the left. Easy for him to use the brake pedals while operating the HST. In my opinion, if you have an HST tractor, this is the best setup, regardless of paint color.
So in the end if an operator says they never use their brake pedals I contend their situation is much different than mine. I try to not be condescending about their lack of use. Just suggest they try using them a little and if they see no purpose, so be it.
And if an operator says they use their brakes all the time I contend their situation is different than the reference above. Again trying to not be condescending.
For the operators that never use their brakes, they probably don't need to.
For the operators that use their brakes all the time, they probably can't stop using them.
