. Like Jeff said, forks work well for hauling brush.
Well now... Forks WORK for hauling brush, they don't work WELL.
I recently upgrade to a 2019 35HP tractor and went all in on a 66 inch grapple, and there is a huge amount of goodness in a grapple...
1) When working alone, without getting off the tractor you can load the large amount of brush - on the fly, just scoop, clamp and go
2) Brush falls off the dang forks all the time - you will need to take an ATV out and pick up the trail of brush bits... Does not happen as much with the Grapple clamped down on the brush
3) Cleaning up in snake country - your in OK so you will have snakes, loading brush on the fly and not getting into the mess to clean up - simply avoids the little biters, as your safe on the tractor
4) Firewood - picking up logs - grapple is a HUGE helping hand to securely hold logs while you cut your rounds, with forks you have to add in chains and straps - just extra work
5) Firewood - while cutting rounds - you set the height of the log - saves you back - seeing how you retired from the Marines (Semper Fi) I am sure your back will thank you
6) Other trash pick up - the grapple can grab sheet metal from an old barn, or leftover construction scrap, regular forks simply can not, you have to get off tractor and load the forks
7) Don't forget it is a Root Grapple - you want to clear out some woody brush - the root grapple rips that like it was designed for it - maybe it was...
Anyway - I am still a rookie tractor guy - having had a 35HP now for about 4.5 years.
If I could do it over - I would have had a grapple form day ONE, this is my lesson learned.... let the equipment do the work, and you stay in the tractor seat as much as possible
