Do what you wish, I would not call them asking about anything from osha they have became a joke and I would stay away from them like the plague if at all possible.
I can tell you this though if osha inspected half the mowing crews I have seen they would be shut down, if any piece of equipment is missing a safety feature that piece is tagged out of commission and you are fined, oh and if they tag a piece out of commission never say "you will use it when they are gone" then they will just tow it.
examples of tickets and fines in a minute:
No spindle cover
No weed-eater guard
Ground prong broken off on extension cord
Cut insulation in extension cord
Seat belt not working on mowers.
No discharge chute on mower
Oh and they will check your fluids as well and if your fluid level is low and not allowing the machine to work properly, "brakes, deck operation, etc" they will tag out that machine.
I am telling you they can make your life hell over nothing and they are not smart enough to realize what is the real world, most of the ones I have met where nice and very well college educated, but the common sense was removed from them in college.
