Here are the grabber specifications. 205 Compact Bale Grabber Picks up 5 bales on edge Ideal for compact loader tractors Compatible with the 10 bale edge and 15 bale edge arrangements 205 Working Dimensions: 36”L x 72”W 205 Shipping Dimensions: 42”L x 72”W x 22”H 205 Weight: 340 lbs Requires: Loader with at least 750 lb lift capacity* One set of remotes *Lift capacity is an estimate based on an average bale weight of 40-50 pounds. However, it is up to the individual to determine their specific loader requirements. I have an extra set of hooks so say 350 lbs for the unit and 4 bales at 75 each makes a total of 650 lbs. I can lift and move this weight without needing rear
ballast. Yes I do engage and disengage usually for each bale, but can sometimes swing into two or three before hooking up. Over several thousand bales moved, I have broken two strings - my fault though as you can set the hook spacing to miss the strings. If it happens I stay engaged and just retie with a bit of extra twine. You do not want one of those units that skid across the ground as you cant unload easily and cant pick up and load out of the stack. Also there are some grapples out there without the removable side bar - you do need this. As for a video visit
