The main reason for leaving rakes either in the bunker or just the very tip of the handle just outside of the edge of the bunker (our preferred method) is because it saves the greenstaff having to get off the mower to move the rake when mowing round the edge of the bunker.
When you add up the time it adds about half hour to an hour to a greenkeepers work load if they have to move every single rake before mowing.
Same problem though isn't it, just a different person has to move it (the green staff still have to get off the raker if its left in the bunker so no time saved or any less inconvenient)
