New Holland Fiat — Blow engine at 275 hrs ????

Brought to dealer for emissions recall and now I have a 75k lawn ornament !!! Because the dealer says the motor is knocking bad but it ran fine when I brought it there over 4 months ago !!! It wasn’t even up for its first service The dealer sent off an oil analysis and came back good then they call back and now say the motor is full of metal !! I wish someone would get there lying story right so I’m still out of a tractor that I need and the dealer wants me to pay for a new engine. What a piece of junk !!!
