Mahindra 5570 emission problems

[robbyr]

Maybe has been touched but just a thought have they pulled out the fuel shut off at the bottom of the tank to check for gummed up pitcok or something blocking fuel to leave the tank? I havnt seen a T4 tractor smoke yet at all this was common on T3s with fuel restriction and white smoke.. sorry to just jump in maybe its been spoken of

Our 4500 would run great a few minutes then just shut down. I was dissing a 10 acre patch when it happened. Wait a little while and it would start and run fine a minute or two then shut down. Changed filters. Same thing. I disconnected the shut off hose and nothing came out. Poked a wire up in there and felt some resistance. Finally fuel started coming out. Been fine since.
