Flail Mower Let's talk flail mowers

[jab-law]

Any suggestions for a good heavy duty flail mower for a Ford 1920 tractor (32 HP, 29 PH at PTO)? Price is important, but durability is more important.

I really like the Bobcat Flail. I has robust hammers that throw the rocks forward with a counterclockwise rotation.

I need to mow several acres of very rough land -- bricks, logs, stones, weeds, wood, whatever, with lots of bumps (former industrial site, now reclaimed by mother nature).
Is a flail mower or a bush hog type mower the best for this situation -- lots of rocks, bricks, etc??????
thanks in advance.

Depends who is going to be standing how close (-:
I view rocks, bricks, etc as missiles for bush hog launching, or (minor) knife chipping annoyances for a flail.

I would ;
a) Go through it with a box blade, just the scarifiers down.
b) A LOT of hand picking.
c) Rake
d) Probably more hand picking.

Maybe - only MAYBE a very light cut first to get the weeds down from 4ft to less than a foot, but I would go very slow and careful if there is general trash.

BTW, it ain't MAGIC when a tarp disappears under a flail mower, but it comes out a lot slower than it went in.

Well I was all set to buy a ZTR to cut my 11 acres instead of the brush hog I had been using on my Kubota L3000. Now I am not so sure if a flail mower might be better suited. With the brush hog I tend to cut the back part twice a year but would cut more often if it was not such a chore. With the brush hog it is a full 7 hour job when high. Here on the gulf coast we get plenty of rain (most years but not now) so it can get 4 foot high in 3 months between cutting.

It took me all day to read the entire thread. Slow day at work. As the thread goes back to early last year what kind of feed back do the 2008 or2009 flair owners have on the ones they bought now that they have a cutting season or two behind them.

Did the ebay China special hold up well to heavy use? Any regreats?

Is the Caroni TM1900 a better choise for 10 acres or more. I am sure prices have gone up over those quoted early on in this thread. Any idea what the Caroni TM1900 is going for now?

I cut 7 acres of pasture every other week, when it rains.

I mow my lawn on 10 20 & 30 of the month.

I bought the Chinese flail mower from Betst last year. It was a nice unit while it lasted -- which wasn't long. As you can see from the above posts, I've been trying (or trying to mow) some pretty rough ground.
the Chinese mower is now on blocks, the drum is out and the bearings shot. I only used it for 10 to 15 hours; however, it is NOT a heavy duty machine. I am chalking it up as a learning experience. In the future, I would LOAD the bearing up with grease and keep them that way -- Thanks to IronHorse and IslandTractor and all you others who have shared on this post.

I think I will take the suggestion to go over this land with the box blade and try to collect and get rid of as much stuff as possible before keeping going with trying to mow. However, I also think I will look for a good used 5 or 6 foot Alamo Super Heavy Duty flail mower or something similar.

Tahks for all the comments/ warnings about the bush hog throwing rocks. I was going t get a bush hog, but am tending to think no. Also, the ground I am mowing is so uneven that the longer tail of a 3 point bush hog will defiinitiely get hung up more than the shorter flail mower.

BTW -- this is a great thread. Thanks to all.

I am into the third season with my Caroni TM1900. I've used it on about 15 acres of land that I sometimes cut regularly (once/month) and sometimes (like yesterday, cut only once per season). It has held up pretty well without any serious issues though I have knocked a couple of knives off (rocks), gotten a log stuck in it (removed with crowbar) and just a couple of weeks ago I burned up the original set of belts after being a bit too aggressive with brush clearing after a long day of field mowing(dramatic smoke and gooy mess but easy to replace with new Gates B43 belts). I've mangled the skids (rocks) but have just bent them back into shape (not sure they do anything anyway). The rear roller also has it's share of dents (rocks) but works fine. I grease at least every 8hrs of mowing usually more. Still on the first set of knives and I haven't flipped them yet. I'm very happy with it and would buy again but sometimes I do wish I had an old bush hog to use for the really nasty stuff so I didn't have to risk repairs on the flail.

Yesterday I mowed about 4 acres of knee to waist high mixed grasses and invasive bull briar down to 3 inches (first mowing this year and we have had a very wet year). There were places were the grass was thick enough that I stalled my 41hp tractor running at 2200rpm (2500 is PTO speed) in medium range at about 3-4MPH (est). The mower did a fine job though even with the mulching effect you get with a flail the field still looks like a newly mown hayfield there is so much cut material. The grass was so high that I hit a few well known rocks I generally avoid and I lost one shackle and pair of knives (replaced in the field in ten minutes). That 4 acres took me about three hours but I mowed about half of it twice in an attempt to remulch the "hay" to get it finer and I also stopped in a couple of places to dig out rocks and once to replace the shackle/knives.

I think the delivered cost of the TM1900 now is a tad over $2K from AgriSupply. I have had no issues at all getting parts from them (knives etc) but I bought my replacement belts from a local Gates distributor.

I don't know that the flail would necessarily be faster than a bush hog. I'd be surprised if it was because guys like FarmsWithJunk who mow professionally would probably only use flails if they were really faster and he (and many others) continue to use bush hogs. I do think from my own experience that the cut is much better with the flail compared to the bush hog however. And, compared to my old bush hog (on a different tractor), I really like the compact form of the flail. Those are both secondary benefits though as the main reason I went with a flail to begin with is the safety issue as I mow too near homes, roads and playing kids to be comfortable with a bush hog.

jab-law , An old heavy duty flail with cast hammers is what you need , you also need some horsepower to drive it . This sandstone boulder was poking out of the ground about 3 inches , i mowed it a couple of times before i put my new hammers on and now it just needs a bit of top soil raked over it for the grass to grow on . Stones and bricks just turn to dust with cast hammers . Tame your paddock with an old heavy unit first , then it's an easy job for the lighter flail later .

IronHorse, how many hours did you get from your old set of cast hammers? Is the cut noticably different with the new ones?

I get 600 hours if they are only mowing grass , but only 200 if the area is a mess . I charge $165 per hour in rough country mowing sapplings , rocks , pushbikes , fence posts , water troughs etc laying in the grass (famous words "no theres nothing laying in the grass"). $110 per hour if the area is clean .

Even with the hammers worn out , the grass is a bit straggly but still on par with a slasher/hog .
