Flail Mower rotary mower vs flail

[rhuffie]

I have a several acre hilly property that has lots of grasses and brush. I am attempting to make look "park like". At first I bought a rotary mower. However because of the uneven profile of the land and the fact that I want to be able to remove short saplings and withstand the occasional run in with a foreign object, the 60" rotary mower does not do a very good job.
It seems like I need more of a muncher rather than a mower. Would a flail attachment work better?
I am running a L3902 Kubota with 30hp to the PTO.

I use my medium duty rotary for rough areas, heavy brush, and the occasional sapling. It can take more of a beating. Just be sure to use the proper grade shear bolt or that the slip clutch is working properly.

I use the 6 foot Caroni flail with Y knives in semi-tamed areas, old pastures, roadsides, and in similar cleaner areas. I replaced all the blades, clevis’s and bolts last year so I still baby it a bit. Belt driven so they will slip if needed.

The really thick stuff with small trees (6”) I hire a CTL forestry mulcher by the day. It can grind stumps even with or slightly below grade. Awesome machines. Just a bit costly. Then spray herbicide, rotary cut, and hopefully one day the area will be tamed enough for the flail.

Seems if a rotary cutter is not handling saplings or debris well enough, a flail would be worse.

Renting a FECON self propelled forestry mulcher for a day or two will be easier to do as you will be able
to remove everything and also dig below the surface to shred the stumps.

It's the size (unwieldy) and the unevenness of my land that's the problem with the rotary cutter. This is about both fire protection and aesthetics....we live in the Sierra Nevada foothills. No farming to be done. The big land clearing has been done already. Now it's just light brush and short/small oak saplings

A flail with hammer blades will handle the small saplings and bushes just fine. But from your description I would use a rotary mower until it was clean and grass takes over. The occasional foreign object will not be good for a flail.

What does "not do a very good job" mean? What's it doing or not doing that is a problem? Without knowing what problem you are trying to solve it's very difficult to suggest an alternative.

The 60" rotary mower is huge and because of it's shape and the fact that the ground is very uneven it leaves parts cut very short whole leaving others at 6"...not good for wildfire mitigation. It's large boxy shape also makes it is very difficult to impossible maneuver around the trees. it seems that if my property was cleared of more trees and had been tilled and then graded to be smooth and flat in big open spaces the rotary would be fine.

A flail will cut uneven ground better IF the dips are parallel to the direction you're mowing. If you mow across the dips then the roller will keep it up on the rises. So it's likely that it won't do much better than the rotary.

Can you use a box blade to level out the land for easier mowing?

Hello rhuffie,

A flail shredder with cast hammer knives like the Del Morino or Maschio flail shredders will
work much better for you as it is shorter in total length and leaving it in the float position
with the top link adjusted so the gearbox is level will allow you to have a good 2 inch cut
for brush management.
