Hi Bruce, It's a 3010T Victa - I think the deck is by Noma. I'll get it off the trailer tomorrow & take some photos. I've checked tyre pressures. The original deck had a broken leg on the spindle - I picked up another mower with a blown motor and swapped decks. The problem is still there, so it must be something other than the deck itself.
