I'll been told not to use weights on the front of a 4 wheel drive tractor because it will wear out the axle. I have a Massey 1225 23 hp. My problem is that my front end will actually raise off the ground if I have a implement up while driving a hill or when I load it onto my trailer. My property has old farming terraces and when bushhogging uphill sometimes the front end bucks up. My buddy sometimes has to stand on the front end while I drive it on to the trailer. Do you think it would be ok to use weights on a limited basis for the situations that I have described, or would it be ok to keep a 100lb or so on the front end permanently?
