I do mostly food plot work, tilling, brush hog, disc and working in the woods dragging logs etc.
You can till and bush hog with 60" implements on a 25-horsepower tractor working flat ground, but you will make slow progress.
A 35-horsepower tractor will handle these tasks with ease with 60" implements working over flat ground.
A 2,734 pound bare weight, 4-WD tractor can barely, barely pull a Disc Harrow with 18" diameter pans. Roto-tillers and Disc Harrows are both soil mixing and soil flattening implements. I would buy only the Roto-tiller, foregoing the duplicative Disc Harrow. If you have any budget remaining, purchase a Cultipacker to roll in your seed and prevent soil erosion.
To pull a Disc Harrow with 20" diameter pans, the first really effective weight Disc, you need a 4-WD tractor of 3,700 to 4,000 pounds bare tractor weight.
If your land is flat you can likely skid trees in HST/LOW at 2 mph with a <26-horsepower engine utilizing a Three Point Hitch cross-drawbar. (Too slow for me.)
CROSS-DRAWBAR ~~ PHOTO #1 A tractor cross-drawbar mounts through the "bullseyes" integral to the left and right Lower Links of the Three Point Hitch then secured with lynch pins. An inexpensive fitting, known as a drawbar lock, Photo #3, couples the cross-drawbar and one Lower Link to prevent...

If you have hills or slopes to contend with the HST on a 25-horsepower tractor will poop out.
If you have hills or slopes over which to drag trees, or want to drag trees faster than 2 mph utilizing HST/MED range, or do ground contact work option for 35-horsepower.
Few here would recommend a 2,734 pound bare weight tractor for use on more than 10 flat acres. Most will recommend a 3,700 pound to 4,000 pound bare weight tractor for five acres of land with hills or slopes and flat land over 8 acres.
Subcompact and compact tractors under 3,000 pounds bare weight operate in landscape, kitchen/commercial garden or hobby farm applications on one to ten
flat acres.
~~ BUY ENOUGH TRACTOR ~~
When considering a tractor purchase bare tractor weight first, tractor horsepower second, rear axle width third, rear wheel/tire ballast fourth.
