I bought a massey ferguson 1529 it has a iseki motor in it .The motor is very powerfull and is very good on fuel .My problem is it smokes like hell when i start it when its cold .It always starts it just smokes for a minute or two i am running off road deisel in it i dont know if that makes a differance or not .it's a 30 hp motor and it runs great with all kinds of power.i am thinking of adding a block heater to see if that helps the tractor only has 35 hours on it so i dont know if that makes a differance or not.any input would be great .
