im still not trying to be mean (i think the new setup looks nice) but when a zero turn starts sliding its the rear wheels that give. i know and understand riding front brake down a hill would help this but to try to build and sell this item i just think not ever gonna work.
i have a secernao that happened to me, i slid down a about 10 foot very steep slope and at the bottom was a high curb now if i had brakes on it and hit the brakes the rear of my mower would have maybe flipped from getting cought on the high curb making the mower flip on me. this did not happen to me i slid down sideways and slammed into the curb... your building something that needs the perfect secernao to work. and like another post, you are giving ideas that well i got brakes so you can do something that you should not try
