    2005, 4720 345hrs, vibration/ high pitch grinding from front while in road gear on pavement 15mph. Seems to get worse when going down a grade and starts to coast.

    I recently bought a 2008 4720 cab with 900 hours. I am having a recurring problem with the pto. It came with a mid mount mower. Every time I mow with either the mid mount 6' mower or my 7' brush hog, after about 20 mins of mowing and I disengage the mower (pushing the yellow switch), the pto...

    Hey guys, I'm new here and only just qualified to be a bonafide member. I am the proud new owner of a shiny new"ish" 4720. I got it from a dealership that had used it for demos and rented it out a bit. I got it with a brand new loader and box blade, and they detailed it up to look as good as...
