Adding to the posts by 2manyrocks, with a L2501 I think you're between saving some bucks with the MTL RG7 at $1700, it gives you 60" width but it weighs 530lbs.
Or the EA Wicked 55", which weighs only 240lbs yet can probably take the most abuse at $2500.
The 3rd option is the Landpride SGC0660 60" which is approved for the L tractors and price is hard to find online but should be approx $2200-2500 and I can only find one post listing weight at a surprisingly light 260lbs... that would need verification.
These grapples are different designs each with their own specialty. The MTL RG7 is the independent grabbers with the long lower teeth for carrying, the Wicked 55 is a toothed clamshell with the short reinforced root rake type lower teeth, the SGC0660 is a no-frills clamshell with no teeth and no extra gussets.
Most other options are either too light weight or too expensive for an L2501. For example the EA Wicked 60" is $3450 and the Land Pride SGC1060 is also around $3500...
