According to Tractor Data your loader can lift that weight "At the pins".
I always look at the load path to the ground to find the weakest link. You have 2K hanging out front of the pins so let's adjust that to say 2400 pounds for leverage. We can then add the weight of the loader itself of about 750 pounds, we are now at around 3150 pounds. Then add the tractor weight of maybe 1500 pounds to get to about 4650.
Now the weakest link, start with your tires, are they rated for 2325 pounds each (that will be on the tire)? Then the front axle (2335 on each axle end)? Then the single center pivot pin that supports the tractor on the axle for 4650 pounds? Etc. If you can answer yes at each point then just be careful and use a counter balance.

Also bear in mind unless you are in 4wd you will have nearly NO braking ability with the rear axle "unloaded".
