To the person with the bad review based on the tractor being a danger to operate, learn how to properly equip and use a tractor. The manual states that there needs to be a rear ballast for safe loader operation. All tractors need rear ballasts for safe loader operation.
My tractor is identical to your tractor. I have rim guard loaded rears and never have had the issues you have. I often have a 7-foot back blade on it as well. I rarely even need 4x4 with this set up. My tractor is exclusively used for digging, pushing dirt, tree removal and snow removal. As far as the front axle leaking, that is an issue that your dealer should take care of. It’s not normal on a tractor that new. Mine does not leak. It has low hours but it is still nearly 5 years old. Find a different dealer or call corporate to get it resolved.
