I am ready to purchase the next attachment for my 1025. I am looking at box blades and am not sure how big (wide) I can go without exceeding my traction with R-4s? I definitely want one that is compatible with my iMatch hitch, not sure if makes a difference between Frontier, Land Pride, King Kutter, etc. I am thinking 60" since this is just slightly wider than my bucket. But there are also 66" box blades on the market too. I don't anticipate any really heavy earthmoving with this unit, just driveway maintenance and some reworking of landscaping in my yard. What box blades make/model are others using on their 1025s?
