Backhoe Kubota 4520A Backhoe

[jturpin]

I found a Kubota backhoe BL4520A this morning for $1200 and I am going to put it on my green tractor. When did they produce these and who made them for Kubota? I need to fab a seat onto it to have somewhere to sit. Also when you hook it up do you remove the lift arms and top links.
