I don't know if this is relevant but it may help you estimate yours.
The book says my YM240 should weigh about 1800 lbs. With the big West Bend loader (which might be the same thing as your loader), the HD front axle for the loader, and oversize rear wheels/tires, but no ballast anywhere, and before I had the ROPS, its scale weight was over 3,000 lbs.
So I would guess minimum 900 lbs for your loader, maybe far more if it looks a lot heavier than mine.
Also I was told my small 3-point backhoe (6.5 ft dig, 7.5 ft reach) weighs 750 lbs. That feels about right, when I raise the 3-point. You might be able to estimate how much larger your hoe is compared to that.
Hope this helps!
