Cannot seem to find the manual for this model of ride-on mower. Being as how I am in the UK maybe the model numbers are different so if I describe the mower perhaps someone will recognise it. It's 16.5HP twin brigs+stratten engine, hydrostatic transmission, 42 inch cut, ride-on mower. The steering is virtually gone, its "clicking" like mad when you try and turn, so obviously needs some parts. Any help greatly appreciated. Thanks Derrick.
