My brother signed the papers for a DK35SE recently, it has the FEL, filled rear AG tires, and he ordered a 6ft. W.R. Long front mount snowblade which will be used on a 1/2 mile gravel road. He has operated a MF 35 for over 20 years, so this will be very new technology to him. I've cautioned him about FEL operation, and recommended rear ballast when using the FEL. What maintenace tips and operating tips would you suggest to smooth this transition? He will mostly be using the tractor for snow removal, very little "farming" in the traditional sense.
