I used my 6ft landscape rake with the tractor, to clean out my fence rows on newly purchased property. The rake pulled everything forward about 15ft, making a parallel row of brush to the fence row. Rake pulled out old limbs, weeds, leaves a foot deep. I could then scrape/drag brush into burn piles. It was a bit time consuming but lots faster than trying to clean all that mess by hand! After raking I could see the growth I needed to drive over with the brushog on a high setting to prevent breaking anything. We cut new growth scrub that was in the way. Raking worked out well for cleaning before mowing. Nothing had been done in fence rows for 30 years!
The tractor 3pt hitch allowed me to lift or drop the landscape rake on selected area, move forward to the collected brush row to drop the load. Spring teeth would come across small stumps, roots, without breaking or losing what they had collected. My rake has no wheels to catch on anything in the brushy fence rows. Not sure if you could do that with a UTV and rake. Maybe a rental tractor and rake? I was able to get quite a lot done pretty fast.
I don’t rake it clean anymore, just keeping the fence rows mowed keeps things clean and nice. Leaves fall, disappear into mulch as the seasons pass. Leaves left on are nutrition, helpful organic matter for the soil. I can see any big sticks/limbs now, pick them up when I mow to get them out of the way.
