If it is anything like the groundsman at my local state school, then you have the easiest job in the world.
He mows the oval with a Kubota mid-mount, then spends the rest of the day raking up the clipings with a rake and throwing them in a trailer. Half of the time he is leaning on it chatting up the mother's who think he's a stud. I have half a mind to throw a quote into the headmaster to stir things up.
