Flail Mower Let's talk flail mowers

[Dan in MN]

Can the mower be run higher? I'm looking at used ones from Alamo, Ford, and Deere.

You could just keep it lifted with the 3 pt, but that is going to bounce around badly and be very hard on the tractor. Also not going to cut that well. A 12' batwing like a Woods BW12 will go up to 8" I believe, but that's a much higher price category unless you maybe have more to mow with it or can pick up some side work..

I've got a question about flails and pasture mowing. I'd like to get a flail as a replacement for my old Woods 214 batwing, run by my IH 385 (36pto hp).

I mostly mow horse pastures on my property to keep them "clipped", when the grass seeds out I mow it back down to below hay height. Normally it's still 8-12" tall after mowing.

From what I understand a flail cutting height is controlled by the rear roller, and from what I've seen most only go to a max of 5-6" cut height to keep the roller in contact with the ground.

You are correct that most flails only adjust up to 5-6 inches. However, I don't see any reason that you couldn't bolt on an extension piece to allow the rear roller to be adjusted for a 8 inch cut. You'll give up mulching as that depends on recutting and I doubt that would happen much with such a high cut.

The only flails that will run that high or nearly so are the higher horsepower-100 HP+ flail crop shredders.

If you have a flail mower raised to its highest cutting height it loses efficiency(pressure gradient)
to cut and lift the clippings up and over the flail mower rotor.

You could purchase a Vrisimo flail mower with rear tires in addition to the rear roller to aid in maintaining a higher mowed height.

Not sure what happened to my first reply but here it is again....

You are correct that flails are generally limited to a max cut height of less than 5-6 inches. I think that is partly because you won't get good mulching if you try to set it higher. That said, when I want to cut higher (usually just first pass in very lush spring grasses taller than 12-18"), I just use the 3PT to raise the mower off the rear roller. Cut won't be quite as even if the land is bumpy but it does work. If you wanted, you could modify the flail rear roller attachment points by inserting a spacer. Bolt the spacer to the "normal" rear roller attachment points and then bolt the rear roller to the spacer. You'd have to figure out the geometry and drill some holes in a ?1/4" x 8" piece of flat stock but I don't see any reason it wouldn't work. If it were me I'd just try the 3PT raising first and see if that gives you a satisfactory cut.

============================================================================

Purchasing a TM model Caroni Flail Mower with 2 rows of slide slicer knives sized for your mules power would work well fro you and provide you with a good looking mowing job,

If you examine Island Tractors uploaded images from the reclaimed farmland he mows you will see how well his TM model flail mower mows his farm property.

Slight correction to Leonz's description. I'm not with my mower now but have spent enough time replacing knives and clevises lost due to rocky conditions in New England to say that there are four, not two, rows of knives. I believe there are seven stations on each row and each station holds one clevis and two knives. Total of 28 stations and 56 knives. The adjacent rows are offset slightly to provide full width coverage. I think the rows at 1 and 180 are identical except for offset as are the 90 and 270 but I don't have access to the mower right now to check. I've attached a few (bad) photos so you can see the basic set up. And, yet, that is a piece of firewood jammed in the rotor on the second photo (no harm done). The mower works well in "hay" and also in light to medium brush up to and inch or inch and a half. It will cut more than that but requires slowing down.

Why not either fabricate or have one fabricated a dolly to hold your current rotary cutter or the flail mower at the height you want to cut?

Maybe simpler would be to adapt the type of cantilevered rear wheels used on rakes or some finish mowers to maintain a given clearance. You could just weld a couple of hitch receivers on to the top of the mower and use 2x2 tubing to reach out to a wheel assembly.

Still in my deciding phase since agrisupply is sold out on the tm1900 atm.

While waiting I came across an alamo shd74 for about the same price I can get the tm1900.

Are there any benefits to getting a heavy duty flail over the medium duty tm1900?

 

[leonz]

If you can purchase a heavy duty flail that has only been used seasonally all the better as
it will have plenty of life in it as the steel used to build it is much heavier.
You also need to be able to raise it with the 3 point hitch on your mule.

I think mainly just the durability and toughness. I can tell you that my beat up SHD88 that I got has taken a severe licking before me and from me and it's still ticking. Just a very tough mower and lays the grass down very nicely! I haven't regretted that purchase for a second.

We had/have some areas that have lots of heavy brush and sumac as well as very rocky soil around my neck of the woods. As we've gotten things cleaned up I now have lots of areas where I could use a lighter duty flail but I have no reason to have to go get one because the 88 lays down a very nice cut already.
