I'm investigating skid loader tree saw and shear options. I have narrowed my search to Turbo-Saw, Dymax-Qwik Saw, and Robo-cut. However, I'm open to other brand suggestions. I own a "standard flow" 763 Bobcat skid loader. Hydraulic flow (psi) seems to be an issue. Most saws perform best or only with high flow skid loaders. I have trees consisting of elm and cedar ranging from 3" to 20" diameter. Any input on saw performance and or challenges is welcomed. What options and issues should I be privy of (ie: saw teeth replacement, blade thickness, etc.)? Any thoughts in support of a shear vs. a saw...I'm leaning towards a saw. Can a shear be matched to my skid loader tree cutting capacity and accomadate a larger diameter tree? Any and all Title comments are appreciated.
