I picked up a Deere 390 Flail mower at auction for (60$) last fall. I had to do a little welding (1 hour) ,replace an oil seal (12$) and replace the fine cut blades (200$) on it. I love it, it cuts light brush (less than an inch in dia.) good and centipede grass good. On Pensacola Bahia I need to slow ground speed by half and probably sharpen blades. On Cogon grass it does well , but it bogs down if it is more than three feet tall. I love the fact that I can cut past the width of the tractor tires now. It is on a Kubota L4200 DT with about 37 Hp at the PTO. I do not know how much detail you might want but I will answer questions.

Thanks for the good pics. Some of the mowing job would be great addition too. :)

Is it 90" cut width?

Greetings,


I am glad to see you found a flail mower in good condition to own and use.

you have an excellent investment in a quality appliance that cuts efficiently

and will not throw objects and injure pedestrians or animals.



What you should do is buy a spring slip clutch PTO shaft the length of the

one that is on the mower now to avoid stalling issues and destroying belts

which are the normal B sized V belts because of that.


Please be sure to check the condition of the drive belts if it is not chain

driven as the belts will rot inside or outside because of age and ozone.

If you find that the belts are checked or cracked they need to be replaced.



The best belts in my opinion are the Gates green brand belts which are

heavier in construction and weaving the fabric most belts are made of is made

from man made thread used to make a conveyor conveyor belts inner

webbing.



Do not worry about the mowers age as you can buy parts from many sources,

There is a flail mower parts supply site here on the web that offers a huge

selection of parts.



The flaill mower will chop the living daylights out of the grass already cut

and it will degrade quickly and have very little dead brown brush on top.


Mowing wet grass with the little monster is no issue either:laughing:



If you have not done it already- be sure to buy fine thread nylock nuts and new fine thread bolts for

the knife hangers- or use blue Loc tite


If you have not replaced the bolts already; socket head cap screws-allen head bolts are

the easiest to work with when you are laying on your back trying to remove or install them

as the allen wrench will not slip as easily off the bolt head. cleaning the wrench hole is easy with a

scribe or very small thin flat blade screw driver.


Buying one or more ratchet wrenches for the size bolt head nut you have will help a lot if you do not want to change

the original bolts to the allen bolts.


You will save on scraped knuckles and filling the swear word jar with 10 dollar bills with the fine thread allen head bolts though as they should be a 3/8 bolt with allen head lock washers-2 per bolt, fine thread nuts with blue loc tite or nylock nuts-changed at every removal and if you can buy the spring lock knife hangers for the knives all the better



You should check the flail mower knife site or take one of the knife hangers to a farm

equipment dealer that handles Matthews Company flail shredders/mower/grain driers

as you can buy knife hangers that are spring anchored which simply slide over against

a spring and washer arm to change the knive blades-takes a few minutes to remove them all and

change to the other hangers but having theses knife hangers are a blessing to change knives or

flip the 2 sided grass knife edges or flip the overseeder thatcher knives.





One more flail mower convert, many more to go, in the creation of the flail

mower nation.:thumbsup:

A flail is absolutely on my list. I like the compact design as well as the other advantages mentioned already.:thumbsup:

The imported Berti flail mower can be ordered for front mounting on your Kubota beast of burden. Berti imports them for sale on this side of the pond I believe-its been too long since I looked for the main importer-The gentleman who imports the Ferrari tractors on the west coast. I am unsure if you can buy a front mount Caroni from agrisupply but you should order the anti scalp roller for the front side/open side of the mower-stops the mower from leaving beaver teeth marks in the edge of the asphault as you cross over it from side to side or beaver tooth marks in concrete curbing while working.


Another true believer/convert for the Flail Mower Nation-onward, forward ever foward as has been said by many.
