Hi, I have a early 90's Bobcat 642B Skidsteer and I am looking into putting a sweeper attachment on it I see they make a 60" and a 54" obviously in most cases bigger is better but in my case is a 60" setup too heavy for the machine, I got a yes and no answer from 2 different Bobcat dealers so I would like to know if any of you guys owned or operated a 642B with either the 54" or 60" sweeper attachment and which you prefer. I do only small to medium size lots and only 6 or 7 for spring cleanups, Thanks in advance for any advice.
