john deere lx 255 hydro question...does it hurt the trans any if i move the mower by pushing it?..there is a lever in the back that is labeled (pull to move mower manually)..reason i ask is i've been reading that it's not a good idea to move a hyrostatic mower like that...maybe not a good idea to move it without pulling the lever? i'm new to a hydro so forgive if i ask some dumb questions
