I'm glad you posted that link.. which are the blades that fit the Caroni? Or are there options? Mine will be a light use unit most of the time.
No those are not the blades that fit the Caroni. I'm pretty sure that if you search this thread you'll find exact Flailmaster part numbers that I posted a couple/few years ago for knives and clevises for the Caroni TM1900. I'm on my cell phone now so cannot easily search until I get home. Let me know if you have trouble.

33 I further investigated. I can spend another $100 and try the inverted V side slice blades. If there's improvement I'll report it. If I get the same results I'll report it and sell the mower.

Good luck. Hope it works out. Are you getting both blades and attachment hardware? I'm just guessing but I think you'll need a clevis or strap of some sort to attach the Y/l blades. Not sure if your current setup already includes that.

Yeah, I'm calling "forward-down" as same-direction-as-tires... I'm calling "forward-up" as opposite-direction-as-tires.
"forward-up" is not possible, the shaft either rotates forward or reverse. I would call it "reverse-up", since the shaft is rotating opposite of the tires when moving forward and the cuttings go up and over the shaft. :2cents:

TomAto TomAHto ... In my opinion, "forward-up" makes more sense. :D I'm sure we're both wrong anyhow, there's probably a technical term.

Here is the text of a post I made in 2010. I doubt the prices are accurate but the part numbers should be.

""I know this is a general flail thread but as there are a lot of Caroni users and potential buyers reading it I thought I'd give some info on replacement parts that might be of use. All parts are available from AgriSupply and they are pretty good about shipping quickly. However, the cost of their flail knives and associated hardware is pretty high compared with what Flailmaster sells. Unfortunately, Flailmaster doesn't carry Caroni specific parts and they don't sell metric parts. Still, through trial and error I have found a few things that might be of help.

First, the Flailmaster M-108381 heavy duty forged knife is exactly the same dimension and weight as the Caroni flail. They cost $1.45 each or less than half of what the Caroni flail costs from AgriSupply. Over time you'll definitely need some to replace losses (especially if you are in rocky areas like New England).

The other parts that need replacing with the flails are the clevis and nut/bolt. AgriSupply charges dearly for the clevis at $6.49 each. The grade 8 10mm x 80mm nut and bolt costs $1.39 which isn't too bad.

I have found that nearly all my replacements have come as a result of clevis failure. Of course if the clevis fails you lose both knives too. The nut and bolt need to be replaced too so each loss mounts up to over $13 in parts if you buy from Caroni.

Unfortunately, I have not yet found an alternative source of the metric sized clevis. Basic dimensions are 55mm tall and 45mm wide outside with a 10mm bolt hole. Flailmaster does not have anything that matches. Closest thing flailmaster has is their beefier M100761 which is just a 1/8 inch too wide and one ounce heavier. I could live with one ounce heavier especially if you replace all of them but the clevis is too wide for the Caroni mount. I tried grinding one to size but it leaves the ears being narrower than the original Caroni clevis ears so figured that was not a good idea. Too bad as the bigger gauge Flailmaster clevis costs less than half of what Caroni charges for a smaller gauge and the larger one would be more durable.""

Note that since that post I and others have found that the Flailmaster clevis can indeed be made to fit the Caroni. It just takes grinding/flap sanding about 1/8 inch off the shoulders of the clevis and pinching the clevis together with a good vise. It only takes about three minutes work each if you do them in batches.

And, I don't worry about the slight extra weight of the flailmaster clevis either. I have about half flailmaster and half Caroni clevises at the moment. Every time a Caroni clevis fails it gets replaced with flailmaster knives and clevis. Haven't had any failures of flailmaster clevises since I started using them a couple of years ago.

This is what Alamo calls Foward Rotation, leonz calls it ccw, would this be "forward down"? My front mount rotates the other way, opposite of tire rotation moving forward.

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

AS my power wigged out before I was able to finish this today GGGGGRRRRRR!!!!!!
I will start once more.

The way Alamo Industrial has configured these flailmowers allows them to be used
with hydraulic drive using PTO shaft mounted pumps and hydraulic motors for the
rotor drives for the wing mowers and or simply rear mounts and in some cases
allowing three flailmowers to be operated at one time with one or more flail mowers
in the raised position.

They advertise the same mowers for sale in Europe. I am unsure if they are built here
or in Europe but with MFN status "Most Favored Nation Status" between England and
the United States; they may be built here with metric parts anf then shipped simply using England for an finished inventory and parts depot.

NOW as you look at the sie view of the flail mower look closely at the mower shroud where
the pressure gradient is created by the high speed rotation of the flail mower rotor and the
free swinging flail knife pairs.

Follow the arc of the shroud to its end where it meets the rear apron where a portion of the
clippings hit the lower shroud and the balance of the clippings bounce out after hitting the rear roller.

NOW the mower will clog in Heavy and tall brush unless the mule is crawling on its first pass.
The Maschio flail mowers sold with the Land Pride brand get around this by having a trash door like some of the original Mott flail mowers This allows the end user to have the ability to mow real deep crap with a smaller mule and avoid plugging the flail mower and or burning a set of belts.

One of our members purchased an alamo flail mower his contract mowing work and as far as I am concerned they took advantage of him and have felt this way from the beginning of how it started for him as the Alamo salesman praised theier mowers to the heavens.

He ran into problems with clogging and damaged knives the time needed
to repair broken knife sets in difficult highway mowing conditions with garbage
and debris hidden in the grass tracts he is or was mowing.
I think i remember stating that he contract mowed 18,000 plus acres of highway shoulders and verges with a brood herd of rotaries and medium horsepower mules in the State of Kentucky.

I am unsure nor do I remember what mowing speed he used or if he mentioned
it when using the Alamo flail mower he purchased. Time was-or is money for him
in a mowing season.

If he had been sold a wide high horsepower flail mower/flail shredder like a
15 foot cut model 1700 Hiniker flail shredder he would have had a much
different experience as he would have been able to have a flail mower that
could be equiped with a running light light kit, end towing kit, skid plate and
hydraulic lift cylinders to speed both the haulage of the flail mowers and the
set up of the flail mower prior to mowing and with a fifteen foot cut operating
at 2 miles per hour he would have been able to mow
at 176 feet per minute
times the mower width 15 feet wide = 2,640 sqaure feet every two minutes times thirty minutes would allow him to mow 1.8 acres per hour at 2 miles per hour in a straight line
BUT the width of the mower saves return trips and reduces overlaps and mowing can be
faster with different mowing conditions.

In saying that it is hampered by its width in narrowed mowing areas where space is limited
for maneuvering.This can be overcome with a narrower cut flailmower of course with a high knife count to maintain a 2 inch cut.

Saying that a flail shredder is a much stronger mower than a standard duty flail mower
and Farms with junk was not treated as I would have wanted to see him treated as the
Alamo industrial salesman should have not sold him a flailmower in my opinion and told him he needed a medium width flail shredder for the work due to the conditions and the acreage
he was mowing. He probably would have recieved more rotary cutter sales if he had been
honest about it as he most likely knew about heavy crop shredders in my opinion.


This is where a front mounted flail mower on a bidirectional tractor would shine in
performance as a standard flailmower could be mounted on the front or rear of the
bi-directional tractor in the example allowing for faster mowing without the need
to turn around saving time, fuel, braking, and tires by simply dropping the wider
flail shredder near where it can no longer be maneuvered safely and finish the mowing
job with the smaller width flail mower shredder. when that section was done the
operator would simply travel to to next location by end towing the wider flail mower
to the job and then re-attaching it to the bi-directional tractor to begin mowing again.

I will tell you that the ditches along the roads on the secondary highways in
New York State look like crap from the lack of mowing- I am still waiting to see if
they mow my ditch.


I am not trying to make a mountain out of a mole hill here, honest but I quite often
expand on the subject of flailmowers as quite often happens and I try not to be boring about it.

No you are not wrong TSO it all depends on the design of the mower
shrouds discharge point as I mentioned in my last post.

Having a rear door on a flail takes away one of the main reasons for using a flail, safety. Mott's have never had a trash door. There are so many variables with mowing it's impossible to know exactly why certain problems occur without knowing the exact details. Too wet, too fast, PTO too slow, not enough HP for the job, wrong knives, etc. Interstators hyd's don't run off the PTO. How could you use the rear 3pt. mower? The hydraulics are run off the crankshaft at the front. Alamo flails are designed for tall grass and weeds up to 1" diameter. If a sales rep recommended them for brush cutting he should be fired. Alamo does have front mount Versa-Pro set ups for bi-directional tractors with Interstator style side wings. These set ups as well as Interstators are not cheap but the widest models cut over 21' wide. You would get a little better cut with a front mount because the tires wouldn't have pushed the grass down. I would like to see a brochure for a flail mower that mentions pressure gradient? Flails create a lot of wind but that's because the knives have to spin fast enough to do an effective cutting job. If you look at a flail spinning, it looks like it is moving from one side to other because of the way the blades are staggered on the rotor.

Thanks for the info ArcWeld - I really like the Motts/Alamo mowers so it is interesting to read about them and the design.
