Flail Mower Let's talk flail mowers

[troverman]

...I have a Kubota L2501 and have 5 acres that are sloped, with trees, mostly grass/weeds, not overgrown, contain rocks of which some are loose and some are part of outcroppings that go down farther than I have been bothered to dig....What I think my options are-

Appreciate any advice.

Here's some advice: your tractor has 19 or 20.5 PTO horsepower depending upon if it is hydrostatic or gear transmission, respectively. It looks like you're considering a 60" flail mower. If you are going to encounter very tall grass, that tractor is going to be overwhelmed. Twice every year, I mow a landfill cap with nothing but field grass on it...using a 48" Vrisimo flail mower operated behind a 29HP Kubota with 21 PTO horsepower. Its about a 30 acre job on a 1/3 slope. It has always gotten the job done. This year we had heavy spring rains and then warmth. The grass was thick and approaching 3-4 feet in some areas. My tractor was overwhelmed despite only turning a 48" flail. I ended up putting this small flail mower behind my 45HP Kubota and even with that machine there were some areas I had to go pretty slow.

So, just be careful before laying out a lot of money. There's no doubt your 2501 can easily lift and pull a 60" flail, and I think it will mow just fine in shorter grasses. But if you are doing a slot of slope mowing like me, be aware some of that horsepower will be "stolen" just to move the tractor up the hill, and if you're in tall grass, it will struggle pretty hard.

First off this is the most impressive collection of flail mower advice written anywhere. Like most people in the US when I decided that mowing with my ride on mower was taking too long I started looking into getting a rotary cut mower. Now I am not so sure.

I have a Kubota L2501 and have 5 acres that are sloped, with trees, mostly grass/weeds, not overgrown, contain rocks of which some are loose and some are part of outcroppings that go down farther than I have been bothered to dig. Previously I was mowing this with a Snapper ride on which has great maneuverability and slow enough to allow me to dodge most rocks. Nice cut, slow as molasses, easy to steer. I won't cut the nice grass near the house with the tractor it is too small with how it is broken up and laid out to be worth not using the Snapper. I know a RC mower will easily roll over rocks and cut anything I throw at it while being near maintenance free. Concerned though that as oddly shaped as my land is and with the hills that don't always allow side slope mowing that it will not be able to efficiently mow as well as a flail.

Now I suspect a flail will be a lot easier to use as it is much smaller. What I don't know is how well it handles hitting rocks, especially those that are buried 20ft deep and don't move when they get hit, or how it will handle undulating terrain this isn't nice and flat. I do have top 'n tilt but not sure how much that will help.

What I think my options are-

Thanks!

*Not my video but this is about what type of land I have if you imagine the terrain in the video at 1:30-2:00 with the under growth cleared and smaller trees removed.

I got a new LP RCR1260 with my L3200. It mowed well & was nice gear. Then I got a $100 piece of junk Ford 917 7' flail. After I got it running ($400ish, new PTO shaft, new knives, torching out & patching bent hood getting hit by knives, etc.) the only time I used the rotary again was for some nasty yucca & when the rotor bearings blew. Much nicer cut on the flail, easier to manuver, safer, etc.

The nearly new rotary got sold with the L3200 when I upgraded to the cab on a L4060. Kept the beat to **** flail.

Your L2501 is identical to my old L3200, except for monkeying with some torque curves to get under 25hp for emissions reasons. The extra missing HP will hurt, but not to bad. You just have to go a hair slower. Trivial with a HST & easier on you & the machine in the long run.

I'd go as wide as you can. 5' minimum, maybe a 6' if it will be manuvervable enough for you.

I mow rocks with my flail all the time. A football sized one finally broke a couple clevises for the first time when it jamed. The rest of the time the knives just bounce & make a racket. The rocks barely move, unlike a rotary that can kill with a rock at 100'+. Mowing rocks definitely beats up the knives, but not that bad. I hear the Carconi clevises break easily, but there are better stronger replacement options noted on here.

I leave top in float when mowing with a rotary or flail. Helps with articulation a bit, but isn't required. The side link really is useless for mowing (handy for hitching though). A properly adjusted flail handles uneven ground better than a rotary as it's so much shorter.

Sometimes the mower is the limiting factor more than the tractor. If your mower is the type that is more enclosed and unable to eject the cuttings quick enough, it might be overwhelmed no matter how much HP is running it. Some mowers provide a nicer finish cut but can't handle the tall tough stuff, while others can digest anything but don't leave as nice of a finish cut. Something to consider when researching flail models.

You only have 5 acres and some of it is around the house ... take some pics, post 'em and lets see what kind of ground you really have. It will help us to help you:welcome: to the Flail Nation

This is what most of it looks like. Hard to see the hills in a photo.



This is my most open area as far as having no trees. Again the slope doesn't show well. I can side hill on this but farther down it gets tippy if I don't watch my turns especially if I have a load in the bucket.





In this part of California the grasses all die in summer and grow a ton in spring.

I didn't read through 400+ pages of this thread but here goes.

Flail mowers had never entered my mind before and the flail mower threads were just something that I passed over while looking at other things on TBN but...

The other day I noticed that my 30 year old Bush Hog TM5 finish mower is getting more and more rust through patches on it, same goes for my 5' Hardee brush hog which is also about 30 years old. I've patched both of them numerous times by welding on steel patches where they needed them just to get by another year. The problem is that I'm beginning to run out of places that the steel is thick enough to weld to.

That had got me to thinking about having to replace them and the cost associated with replacing both. Then I saw where a single flail mower might be able to take the place of both. The only thing that has me wondering is about the durability of the flail compared to a brush hog. I have very few rocks but have the usual small bushes and trees up to an inch or so in diameter that sprouts every year or so. Most mowing is pasture and along the edges of planted pine trees.

When it's time for me to do something do you think the Caroni flail mower would do what I need it to?

I don't dispute that tall lush grass will require more HP but I've never found that to be a problem. Yes, sometimes in the Spring I have to throttle up or even cut less than full width on a pass but I'd never get a smaller flail because of that. I'd size the flail for average cutting as it is easy to slow down or take smaller cuts. Not so easy to figure out how to make an undersized flail more efficient with lighter mowing.

I used to do landscaping work in high school and we always bought mowers that were the fastest to use on 90% of what we cut. If we got into thick spring grass for a bit we just cut less per swath and made it for it the rest of the year with the faster mower tenfold.

I had the same dilemma when we bought our flail, we've got a ~19HP PTO Ford 1500. One thing the dealer brought up is that there's a "fixed" amount of HP that goes to just keeping the flails spinning so when you go with a 6' flail you may hit patches that will actually be slower to mow than if you have a 5'.

Another big factor is how close you plan to trim. We're just upkeeping the pasture here so we trim at 4". I can run through thick brush and blackberries up to the hood about as fast as my butt can handle it but if you're cutting low + thick grass that might be a different consideration. We went with the Caroni 54" so we'd have the versatility of cutting thick stuff but really up to what you want to do with it.

Being in California my dealer was recommending a Vrisimo for about $4k. They look like a well built piece of equipment but they are 2x as much as a Caroni. I haven't seen the Caroni but am curious if a machine built in Italy and shipped to the US can be 1/2 the price and near the same quality. Obviously I would much rather spend 2k than 4k but not having the experience of using a Caroni vs a premium brand I am unsure of what my extra 2k is getting me.

I watched your video again. That's some breath taking ride down those trails. I see you're not taking my advice of getting some goats or sheep and still shopping for a mower. My Mott mower wouldn't have any trouble cutting anything on that video. but my old tractor couldn't carry it the top to get started. Laying all jokes aside I don't envy you having to make a choice on a new flail. 2k vs 4k would have to weigh a lot for me. Lots of folks here have the coroni and have good luck with them on the other hand I'm sure the Vrisimo owners are happy with theirs' also. I would suspect the higher dollar mowers would be for someone that does a lot of cutting say 10 or more acres a week. For someone like me cutting 5-8 acres every 2 weeks I couldn't justify the extra $$.
