I have now found out that this machine is a 4016TRX so that is some progress and you are able to remove the spindle housing without removing the deck. Next issue is the front wheels apparently only have nylon bushes. I can't believe this should be the case as this machine has a 16.5 hp motor sitting up front. Anybody have an thoughts on this? I have looked around and haven't found much info on them and not having see it makes it harder
