The right way to do this is to use a reinforcement ring
Of course Deere had to think of that for the 318, near wrecked my 317 stomping on the brakes trying to park it and turns out they’re separate linkages unlike the 185...After reading the new operators manual that I just picked up for my 318 I saw that when you pushed on the brake it would move the hydro control to neutral. Genius! Those clever JD engineers.I have not yet tried it on mine.
I have a 318 with 44 loader. You are controlling speed, steering and hydraulic functions with two hands. That feature of the brake putting the hydro in neutral has been a very helpful feature.I have owned 2 hydro tractors, one a Cub Cadet and my JD300. I always stopped them using the hydro control, never the brake pedal. It never even dawned on me that the 318 brake would put the hydro in neutral. Crazy!
