Looking to buy an RZT S 54 and I have a hill in my yard that I mow sideways.  It is only about 8' of drop but 50' long so I mow it sideways on my current tractor.  The angle is probably 30 degrees.  Anyone use this mower to mow sideways on a hill that can comment on performance and safety?  Because I mow every week I'm looking at this model because of the 4 wheel steering versus caster wheels up front who I'm told make the rear transmissions work harder.  ??  Thanks!
