I have purchased from 2 MF dealers from new, I was charged for service parts & oils but not labour for the 1st service then parts & labour after the 1st. A dealer will charge dependant on how the retail sale has been done & what you have agreed upon at point of sale.
Best way I have found now to fix my costs is buying a service & repair contract for my intended life of the tractor. I know where I stand for my service & repair costs for 3 years 4000 hours use & as my tractors are dealer serviced I am backed up by my dealer & MF if I have an issue. I hear MF now offer 5 years 2400 hous extended warranty on tractors over 165 Hp & you can add hours for a small additional cost. This is the way for me!!
