Should I be looking at an L3560 too?
Tractor weight is where to start. Horsepower and amenities follow.
L4701 3,300 pounds, bare tractor weight. (intermediate amenities) Cat 1 - 3-pt.
L3560 3,500 pounds bare tractor weight. (de luxe amenities) Cat 1 - 3-pt.
MX -----3,700 pounds bare tractor weight. (economy tractor) Cat 1//2 - 3-pt.
All considerably wider and considerably heavier than an L3901 (2,700 pounds bare tractor weight), which is not that robust a platform for 20 acres.
Rear axles on above tractors are all 10" or more wider than L3901 rear axle, making these candidates much more stable.
L4701 and MX are close in cost. L3560 is more money ~~ and worth it.

The fundamental importance of TRACTOR WEIGHT eludes many tractor shoppers. Neophyte tractor operators are often intimidated by instability of tractors with small front wheels and large rear wheels, therefore frequently purchase tractors too light, too small for long term satisfaction. ((Tractors seem to shrink after about twenty hours of operating experience.))
The most efficient way to shop for tractors is to first identify potential tractor applications, then, through consulataton, establish bare tractor weight necessary to safely accomplish your applications. Tractor dealers, experienced tractor owners and TractorByNet.com are sources for weight recommendations.
Sufficient tractor weight is more important for most tractor applications than increased tractor horsepower. Bare tractor weight is a tractor specification easily found in sales brochures and web sites, readily comparable across tractor brands and tractor models, new and used.
Shop your weight range within tractor brands. Budget will eliminate some choices. Collect a dealer brochure for each tractor model in your weight range. I spreadsheet tractor and implement specs, often a revealing exercise. I have a column for cost per pound.
Most tractors under 3,000 pounds bare weight operate in residential or hobby farm applications on one to ten
flat acres.
Selling a used tractor is easy. Selling multiple light implements in order to buy heavier, wider implements for a new, heavier tractor requires a lot of time. Depreciation on implements is worse than depreciation on a tractor.
A quality dealer, reasonably close, available for coaching, is important for tractor neophytes. Most new tractors are delivered with a glitch or two requiring correction. My kubota dealer is six miles away. I feel my local dealer continues to add value to my equipment after seven years. Dealer proximity is less important for those experienced with tractors and qualified to perform their own maintenance.
