Loading the rear tires simply doesn't allow you to get near rated maximum lift....because it can't. In this example Kioti says you have to put 1,047lbs on the 3pt to max the loader. Putting weight on the 3pt takes weight off the front axle, by using the rear axle as a fulcrum/pivot point. Making the pivot point heavier (loading the tires) does very little to take weight off the front axle. Think of a teeter-toter with the rear wheels being the pivot. If you have a fat kid on one seat, you need another fat kid on the other seat....no real way around it.
My loader is rated at 2,639lbs max lift at the pins, to full height. With pallet forks on, I was barely able to lift the 1,300lb (weighed) slab that became my counterweight. Add the slab, and forks, and it was probably 1,700lbs total load, give or take. The rear tires were extremely light, and came off the ground with sudden loader movements or sharp starts/stops of the tractor.
Everybody likes pics....1,300+ lbs after it was finished (added the legs, drawbar, top link etc).
I'll have to check it out for myself, I've got 1164bls of ballast in my rear tires and I have the hoe on it that I have not taken off yet, she's a hefty girl right now.
There are alot of folks out there that say they have loaded tires, but in reality there is hardly anything in them, I'm not saying that is your case.
Thats just been my experience the 30 years I spent in the field as a tire guy. Alot of folks just don't know that they got screwed when they paid to have their tires filled.
I won't know for sure until try it myself with the backhoe off, you may be right, but I'm a check it out for myself kind of guy.
This is off of Kiotis Brochure for the loader, It doesn't say the weight has to be on the three point.
It just says counter ballast 1048lbs.
