Just bought a 70's JD 510 backhoe. Just looking to determine age and get some parts. On the tag it says its a series E 9900? Any info will help. Thank you

Tractordata lists built from '71-'83. If you're not familiar with closed-center hyd's then you need to do some studying on how it functions.
A good friend sold it to me and another good friend is a diesel mechanic and is going to do the oil, and mechanical on it. They are helping me out. Thank you for your reply.
