Unless you plan on collecting & picking large volumes of brush - keep the grapple narrow. I have a 60" rock & root grapple. No problem handling long lengths of pine trees, very large rocks. Mine is great for chomping up great chunks of earth and transporting.
I took my OEM grill guard to a local welding shop and had this done. I did it BEFORE the grapple. Several posts on TBN regarding damage to grill, radiator and battery. Due to sticks, stobs & limbs.
