I have the R4's on my 230 and I just stuck it in the mud yesterday. I did not want ruts on the yard and I had no problem in the snow. I had a neighbor with New Holland and AG tires help get me unstuck and he ripped up my yard but good. Who cares it is only grass and now I have a good idea of what it takes to get it stuck.
The work light and sign are great ideas. I had no problem with cold starting in N.E. Ohio but my is in a pole barn, I went without the block heater.
I am in the process of building a ballast box. WIth a heavy load it gets light in the rear end easily and I don't want to fill the tires because you can't take that on or off and you cant adjust the weight like you can in a ballast box. I have heard that depending on what you fill the tires with you may get rust on the bead and if you get a flat or puncture you can get tipsey quick.
It sounds like a good deal and it appears that the promotions are not as good as they once were. Once again, if you get it I am sure you will enjoy it.
