There is a *lot* of load on front axle and tires, by the time the rear tires on my tractor leave the ground! Maybe yours has less rear ballast, but this is definitely something I try to avoid.
I think if I build one for the front, I would do it with the frame for the fork attachment. Seems easier to connect, and less weight from the fork frame than the bucket would increase lifting capacity.
I have seen a couple built as 3pt hitch attachments. The 3pt multitool I am building will be able to do this, but I probably won't get around to finishing this aspect until I need it for something.
I will watch the vids when I get a chance somewhere with wifi, probably the questions I have are obvious from the vids. I am guessing the motive was mostly about extra reach..
Did anyone operate both the double and single boom versions, and if so, any observations?
I always try and put the heaviest implement I can on my tractor when doing work off the front end like this. I noticed Paul and his team did as well. For me, my heaviest 3 point hitch implement is my 7 foot snowblower, but a person could also build a concrete counterweight, or use a 55 gallon drum filled with sand. I have a fertilizer spreader that I can fill with sand as well, and that makes for a nice counterweight off the rear of the tractor.
