Welcome to TBN. I'm not familiar with the exact model you have, but recently on TBN there was a thread discussing what size tractor is needed for FEL round bales. The general thoughts were:
bales vary from under 1000 to 2000 lbs
the 3ph with bale fork or spike will lift a heavier bale than FEL
rear
ballast is needed, loaded tires are where most people start, then add more
a 50 hp tractor is the beginning point for using a hay spike
a hay buggy is another choice for smaller tractors
You say "load" round bales...where are you trying to load them...how high a lift? how big bales?
If the specs for your FEL are actually 1100lb loader lift, then I see no way it would lift almost any bale, since the entire bale sticks out in front of the lift point.
You say you have just purchased the tractor and are new to TBN, thus I assume you are in learning mode...as we all are. Hopefully, you have a quick attach FEL. If so, best idea would be to borrow a quick attach hay spike, find a bale in your area, ask owner if you can experiment with your tractor and see how it works.
