For a removal based business a knuckle boom with a grapple saw aka Tree-Mec with an 18” chipper is the cats ass.
Lotta iron, lotta money. That’s why I focus on PHC
My buddy doesn’t play around. Monster Kboom, Mack dump for a chip truck, huge bandit with a conveyor infeed. He will do 200 yards of chips a day some times. The goofballs use a 200t as a chipper saw though.
