I had a
L3200, same loader & frame as the
L2501. I helped a friend move a small barn full of "1,200lbs" big square bales. I got the job done, but it was sketchy as ****. If I recall the loader is rated to 1,200lbs at the pins. Add in a couple hundred lbs for the forks & a decent bit for the load being well in front of the pins & I was well past the OEM rating.
I had a 5' rotary cutter on the back & a small pile of 50lbs bags of stuff on the back of that. Loaded R4 tires too. Lots of
ballast & it was located a lot further back than normal for better performance. It still really wasnt enough. The back end was really light & pretty much came off the ground at least once.
The lack if ballast is guaranteed to be the weak point on the economy L 2 & 3 thousands, possibly the "frame". My new
L4060 on the other hand is rock solid at max loader lift with just loaded tires (I keep ballast on the 3pt pther than that one time). So hydraulics & loader design are the weak spot there. Probably closely followed by the front axle, but that's just a guess. Everything has a weak spot, so that's not a complaint against either machine. Just s matter of where that weak spot is. Hopefully it's a power or ballast weak spot, not a structural issue.
I was lucky if I could lift a bale high enough to stack it on another bale. It depended on how lucky we were with the weight of a given bale.
In short, a
L2501 might be able to lift your bales. But it wont be able to do it safely. You can probably get away with an occasional bale, as I did. But plan on getting a bigger machine if you plan on moving big square or round bales.
