JD 6630 fuel problems

[kevindb880]

Ploughing with 66 and 5 furrow KV, every day after a couple of hours work when you drop the plough in and pull off the engine almost dies, it then picks up slowly and is fine until you turn round and drop the plough in and go again.
All fuel lines, filters and seals have been replaced, once the engine has picked up it drives as normal and will happily plough at 9kph until you turn round and drop the plough in the ground!

Any fault codes in the ecu ??

Dirt in the fuel tank? Had similar problem with my MF 6475, ploughing a field it would come to a stop on the uphill pull the same place, probably a tough spot. Anyway blew back into the fuel tank, and the problem was solved. Be a tank off and clean in the winter.

If she is struggling for fuel pressure under load, you will get a fault code

Had a code and message to change filters which we did, have drained a bit out of tank and it seemed clean.
Will blow out fuel line next and try that.
Was doing a headland this afternoon and every time I tried to pull out of the corners it felt as if it was going to stall it never did, if you give it any revs before you drop the plough into the ground it still died to the the point of nearly stalling.

Tank sock, lift pump, filter o ring, braided lines. Check / replace all.

Tank sock?

Some have a sock on the pick up tube
