Hi all,

Just too update....the owner of the 434 went AWOL.....so seeing I could not contact, I went and got a A414 made in Australia, or partly and assembled.

Anyway, wanted to thank you all, because your posts helped me to understand the machine I have, which shares a lot with the 434.....and it helps with general tractor knowledge too.

So now I am going to start some new threads on this one i have, which had no problem holding a huge blade off a JD that must be 200 or mor HP and needs a ladder to get into...I reckon blade may have been a tonne or few thousan lbs....
