have 1650 w/ allied 595 loader which is quite heavy so i have 16 inch tires on front. use unit for daily chore tractor for baleage and dry hay. last year i broke steering shaft in steering cylinder under radiator. just broke steering arm. i have previously shortenened turning radius with stops on axle. i noticed there was stress by steering arm from before i owned it. in winter, sometimes i drive slowly with a bale in rutts. this is hard on tires, tie rods and steering arm. i am evaluating putting after market (a & i) hex shaft and steering arm. has anyone done this and did it solve breaking problems ? is it more reliable.
