You will not lift and carry 2000# on the forks with a 763. I have one and to move a work table (about 2300#) we had to turn it on it's side (the table) so that the weight was concentrated in the tables 3" thickness and then chain it to the cross bar on the lift arms. We were able to move the table this way but there is no way you are going to lift a 2000# pallet on forks and carry it. The table we moved was a solid slab of steel 3' x 5' x 3" (give or take a little bit) and when we tried to pick it up with the forks, all it did was lift the back of the loader off the ground, the table did not move.
The Bobcat Operation and Maintenance Manual for the 763 rates the lift capacity with forks on page 27.
15.75 inches forward of the backplate is rated at 1115 lbs.
24 inches forward of the backplate is rated at 960 lbs.
With the ROC rated at 50% of tip, you will tip over at 1920 lbs 24 inches out.
One other possible solution is to ask your supplier if they will provide block stacked in half pallet loads. I know we can get them that way from some of our suppliers. The sod suppliers will also do it.
