So I picked up a used but like new Ferri FM155 flail recently for my 1025R. After some grease and gear box oil I tried it out on the highest cut setting. I found that it does not cut anywhere near as nice or clean in taller grass as my Alamo flail, no matter the speed. The knives look pretty decent and aren’t beat up.
Where can I find a manual for this mower and is this generally a good mower or is there a reason for the poor cut?
Hello showroomshine,
The Ferri Flail Mower like all flail mowers is best operated at
the lowest setting or 2 inch cutting height as this creates
the highest pressure gradient/suction pressure to cut and
lift the clippings up and over the flail mower rotor and back
down to the ground.
The Ferri Family has been making farm implements for
4 generations since 1844 and is a world leader in
mower technology.
You have an excellent mower for all conditions and it will
outlast your current mule and the next one as long as you
take care of it.
With your mower you can flip the side slicer knives to expose
a fresh sharp edge for mowing.
The best and easiest way to maintain a paper cut sharp edge
on your side slicer knives is to invest in a wet well grinder
from the folks at the Micromark Company.

The low speed water bath cooled grinding wheel is the best way to
safely cool grind your side slicer knives.
The wet well grinder sold by Micromark is currently $99.00 plus sales
tax and shipping.
The low speed wet well grinder can be used for grinding sharp edges
on chisels and pocket knives as well.
You can send the FERRI Company an e-mail with the 155 flail mowers
serial number and your physical address and I am sure they will supply
you with an owners manual either by mail or via a PDF file that you can
print out in landscape form which is easier to read.
Happy mowing.
