Flail Mower Let's talk flail mowers

[jthibodeau89]

Finally got the anti-wrap modification on my JD 25A complete. Rotor spins great. Welded the original bolts to the washer plate to make a stud plate with collar. Rotor has about 1/8" axial and radial clearance. The design is similar to what is on my JD390. Just need to add some paint to the drive end plate and covers and it will be ready to mow.

I included a pic of the jack stands on casters that I made to allow me to support and move the rotor when replacing the bearings or pulling the rotor. The stands work great and can extend from 12" to about 21" tall. They will be put to use again when i add the grease zerks to the rotor bearings on my JD 390 Flail.

I love it when a plan comes together, happy mowing Jthibodeau89.

Thanks for sharing the mod for the JD 25A. I have collected 3 of these.....everyone says I have a problem.. 2 I have actually used and one I haven't gotten around to trying out. Just put in a order for 3 belts, 150 FM 7 blades and a batch of nuts, bolts, and hangers. I put new scoop style blades on the 1st one I bought back in 2013.

I saw this on the palletforks site this morning. Might be a solution for those with no PTO on their tractors or ...... no tractor period.

ATV UTV Tow Behind Flail Mower For Grass Mowing In Fields, 48" Mowing Width

 

[Reg]

Overall width of 79" for a cutting width of 48"
Somehow it doesn't seem like a good "fit", i.e. a lot of folk who would be content with 48" cutting width probably have tight quarters where 79" won't fit too well, or if you have that width to get through you would want more cutting width.

Simple solution would be to put the wheels behind.
13.5 HP seem a bit much for only 48" too, given that it isn't self propelled - garden tractors cut wider than that with similar HP.

Anyone have one of their skid steer mounted flails? 69” Hydraulic Skid Steer Flail Mower For Maintaining Fields With Tractor Loaders

 

[PRCWI]

Curious on what their quality/durability is. Price seems very reasonable

 

[whirly]

On their site .... Recommended Hydraulic Flow: 13-21 GPM

That leaves out most of the "tractors" they say it will work with including my MX5100 which only has 9.5 GPM.

It'll work with a skid steer just fine.

13gpm @ 2,500psi (tractor standard) = under 19hp
21gpm @ 3,000psi (common on skid steers) = 37hp

Seems a little underpowered to me. Especially when you factor in hydraulic being less efficient than PTO. Of course this is coming from somebody who ran a 7' flail on a 25 hp PTO (L3200) machine ok.

A tractor of appropriate size for that will not have enough hydraulics to run it. Doable for a skid though.

You have 2 pumps on your L4060HST. One for your Power steering and one for your Implements.The manufacturer adds them together to give you give you "Total Hydraulic Flow" of 14.1 GPM. Considerably less than the 21 GPM you mentioned. In addition, you are only going to get the flow from the Implements pump of 9.4 GPM. See attached from the Kabota site:
