Opinions on Kubota GF1800(4WD)

[Fromjim]

I am thinking of replacing a John Deere 345 lawn tractor with a Kubota GF1800(4WD), this tractor is a diesel with front mounted mower, the JD had a 54" mower, the Kubota has 48,54 or 60" mowers, I would probably go with the 54" again, because of the tree spacing and the uneven terrain. Please feel free to give your opinions and suggestions, price in Canada is $16,700.00 with a 60" side discharge mower, we have about 10 acres with hundreds of trees. Thanks for any help with this purchase.

God bless
Jim
