I've left mine on, but it was so noticeable that I doubt I was able to move three feet. I have to admit, I stomp on that brake pretty hard before I set the lock. Maybe that is why it is so obvious that it is on.True with mine - aint gonna move at all, and she groans too! The little red light goes off in the head...... "hey, dumbass, tap the brake!"....
And yes, I have heard that voice more than once, ok 14 times?
Another thing for me is pure habit. I never jump off the tractor without setting it and always release it, first thing, when I hop on.
