Nothing, but I'm happy of from the time I got it until the time I wrote my quote.
I can't say anything for the future, but I think I will be very satisfy of getting this tractor after having a GC2300 for three years.
I have had my mf1635 since June, no issues with it,lots of power but the larger R4's drag it down on the hills more than my 1532 did. Should be fun plowing with heat this winter and AC for now when the sun finally comes out.
