How old is your blower? What make/model? Also, what consistency is your snow? Light fluffy stuff is going to go further. The David Brown should be able to sling snow pretty well, paired with the right blower.
If you want a forward blower, cab, and enough power, well the Grand L6060 exists.
Fair warning, the Case I linked to is by far the cheaper option. Grand Ls are about the same size as your David Brown.
My blower is a Ford and is at least 20 years old. The model info is long gone. Our snow is mostly light and fluffy typically 10% moisture content. My walk behind 8hp blower can throw the snow higher than the David Brown. Both the front and rear blowers on this B2601 comparison video thrown the snow much farther than my current setup.
