There is no such thing as a heavy
compact tractor. Utility class tractors begin at 6,000 pounds bare tractor weight and they are not considered heavy. Heavy tractors begin at 10,000 pounds bare tractor weight.
As you likely know, the
L2501 and
L3901 are twins except for engine horsepower. You cannot pull a minimally effective Disc Harrow with 18" pans at speed with an
L2501. An
L3901 will just manage secondary tillage, which is NOT what you are intending. A PTO powered roto-tiller is the more effective implement on 2,700 pound bare weight tractors.
You are expecting too much from a light tractor Backhoe. Stumps over 6" are impractical.
The fundamental importance of TRACTOR WEIGHT eludes many tractor shoppers.
An MX without a Backhoe is cheaper than an
L3901 with a Backhoe.
With an MX you should be able to pull 3" diameter trees, including roots, from MOIST soil with chains attached to tractor's rear/center drawbar. This is how a tractor is meant to function. Heavy work at the rear, not the front.

Very generally, a tractor's FEL will lift twice the weight of same tractor's Backhoe.
A Bucket Spade is a reasonable proposition on an MX, especially an MX equipped with Kubota's optional heavy duty, round-back bucket.

You have not related the total acreage of your property, how many acres you will work with the tractor, and little about property topography.
If you put brush or dirt into any creek you are begging for trouble from law enforcement. Your downstream neighbors will rat you out for sure.
