RobJ, is there a PTO guard missing from your mower ? The safety police will be coming for you ! I know you wont get near it but you never know who might get tangled up . When I was a kid one of the workers on the nursery got his pants caught in a unshielded PTO shaft to a sprayer,wrapped him up and almost took his leg completley off,not a good day ! Years later had a woman get her hand crushed in a potting machine that had a guard removed,they may be a PITA but they are not just there for the lawyers.
