Pinwheel hay rake

I have just been given an old pinwheel hay rake of Dutch manufacture. It has four rake wheels, each about a yard and a half in diameter. It's quite a heavy thing, and has a cat 2 hitch.

My questions are, how high should I set the implement above the ground, and how fast approximately should I be driving with it?

Many thanks,

Start off moving with the rake just barely off the ground, with the wheels at 90 degrees to the ground, now lower it til it is doing the best raking with the least ground resistance. The best setting will produce the least amount of dirt and dust, and remember if you try to run it too low the needles will be bent or broken.

If the rake is clogging with grass check to be sure there is no rust on the needles, and that the wheels are at 90 degrees to the ground.

Don't back up with the rake lowered that will break teeth too.

You set your tractor ground speed by the amount of grass the rake is leaving and how your hemmoroids feel. If it's picking all the grass up and not hurting your body then go for it.
