This thing has some odd designed deck height adjuster that uses the deck wheels as the height adjustment at the rear. This then has the wheels in full contact with the ground and then when turning these wheels are forced sideways as in a bogey wheel setup. I'm not sure if this was the original design as the rear of the deck has been re-constructed (possibly because of the deck wheels being dragged across the ground ?). I'm going to see if I can do away with this idea and set it up so that the height adjuster lifts the whole deck up nice and square without the wheels being part of the adjusting system. Anybody have any thoughts?
