I am looking a buying a new GR2120 but I am concerned about the transmission problems I am reading about. Are the new models a lot better now. I will be using it for mowing and blowing snow. When did they upgrade the transmission with bearing instead of bushing. I also read some people saying it does not cut very even. The tractor has everything I am looking for. Four wheel drive, tight turning radius, and shaft driven mower deck and snow blower. The other options are John Deere x500 series but mower and snow blower are belt driven and X700 series is getting a little big in size.
