My cutter is not robust enough to just mow them down as it is rated for only 1" stems. Actually, that surprised me and when I first started, I was probably mowing over 2" stems or even a little larger but I stopped that! I read the manual!
NEW Rotary Cutters cut everything at first. As the light blades dull a light cutter undergoes increasing stress.
25 horsepower will power a Light Duty 5' Rotary Mower
35 horsepower will power a Heavy Duty 5' Rotary Mower
35 horsepower will power a Light Duty 6' Rotary Mower
45 horsepower will power a Heavy Duty 6' Rotary Mower
Using a HD Rotary Cutter of 1,000 - 1,100 pounds you will need an FEL to hold down the front of the tractor on moderate slopes.
I use a Land Pride RCR2660 (60") HD Rotary Cutter with a Class 4 driveline, weighing 1,002 pounds. My 2013 vintage
L3560 powers RCR2660 through Florida jungle mowing over flat land with no complaint and no damage/distortion to the implement. I "try" not to cut brush thicker than 1-1/2". $3,120.00 in May 2018.
I had a Land Pride RCF2060 (60") medium-duty Rotary Cuter with a Class 3 driveline, weighing 620 pounds, nominally rated for 2" brush. It required a ~~$600 repair each year when I would get into brush. It would have been reliable cutting grass. $1,600 in February 2014.
If you buy too light a Rotary Cutter, then cut saplings, it will soon visit the shop.
Regardless of what you buy, order chain guards for the front and rear, not rubber guards and not plain metal.
I tried to push them over with FEL but it didn't work so good.
A Ratchet Rake on your bucket will greatly improve bucket grip on saplings to 2" diameter. Chainsaw any more mature.
I had a snarled mass of wild grape vines and brush near a gate. Decided I should clear it today, before everything emerged from dormancy. Photo #1 Ratchet Rake on bucket. Downward oriented teeth make this attachment excellent for pulling brush and light grading, but you cannot dig a hole...
