currently having an issue with a 329 b serial #t00328b123484 they sent to dealer after it died, dealer said no issues after blowing out fuel lines. came back to site died. back to Deere, couldn't find issues but could not get running. customer loaded up machine and brought back to there shop after months of no progress. new fuel lines filter and inline filter installed. no start persisted. we arrived raised machine, found adequate fuel to block as its integrated fuel system. after fully charged battery lots of black smoke but battery drops down to under 9v as it seems there is a load. bought new battery just to confirm issue was not battery, and it dropped it down to same voltage, now the units left tires spin through brake, while trying to turn over unit. am I thinking to far ahead to remove hydraulic pump? i believe issue of no start is load from pump. my first process would be to decouple pump from drive and start engine to confirm. cant seem to find much in service advisor for tests
! Like Paul said, a serial number is a must. Definitely sounds like we are heading to the lockout system.
