With the light tractors you are considering, you may be disappointed in grapple capacity.
Consider a Ratchet Rake bucket attachment for tearing out brush and consolidating debris into piles. Ratchet Rake is a force multiplier mounted on small tractor buckets. Easy to store when not attached to the bucket.
If you want to tear out roots 10" deep, consider a three shank Field Cultivator/All Purpose Plow. Field Cultivator will also pull debris to a burn pile. Heavy work should be accomplished from the Three Point Hitch. Tractors are designed to PULL.
You can tow tree trunks from the rear of the tractor using chains. Tractors are designed to PULL.

Holy cow...this is very helpful as I am ignorant of all the implement options. Pictures and videos truly tell a thousand words! Thank you. What you say makes sense wrt PULLING and makes needing the grapple much less of a need now. You also might have just saved me $6K because we really like the BX23S. Besides the FEL capacity the only other negative we are really seeing now is the tire size compared to the B's for our frequently muddy property.
