I am in the market for a new 72" diesle zt. I own 2 Horse farms in Maryland. One farm has about 30 acres to cut and the other about 25, thick grass. Like all the added features and value of the Kubota over the JD, test drove the kubota at the dealer very nice machine awsome seat, like the hydro deck controls and foot parking brake and seems like it is put together better than the JD,the thing that concerns me is that one piece tranny. Both 31 HP Kubota(1261cc) vs. Yanmar(1331cc). Will be demo-ing the JD this week on my farm. Also might Demo the Dixie Chopper 35hp Yanmar. Does any one out their have any experiance with these machines.
