I mowed about 2 acres with it on - because I'd only put it on very lightly. Funny smell after a while.The REAL question is, who holds the record for the number of times attempting to drive with the PB set,........ in ONE day?
I very rarely put it on. When my better half drives the tractor she puts it on. Always stumps me why it won't go properly, takes a couple minutes to work out it's the brake.
