SW Ontario | I just bought a 6420 this summer, so I don't have many hours on it. The 6310 we traded had 2000 hours and never had anything go wrong. I suspect I will be keeping this one along time, they seem bullet proof. Both machines have a 640 loader and open station. The one reason for trading was to get the 25mph gear that was not available on the 10 series open station models.
One big thing I like about the new one is that is has ALOT more power above 1500 rpm. It dyno'd brand new at 110 hp, and believe me it has all that and more. However it does not seem to have as much off idle when doing loader work which PO's me a bit.
On a side note it has the SAME turning radius as my 7920 when set at 60" centers...hummpphh. | |
