    Why did you stop selling the Caroni flail? Is there another lightweight/value flail you carry instead?

    We had about a 25% failure rate on rotor bearings (on the drive side) in the first year, and then the race would weld itself to the shaft. It was a 2 hour or more job, plus a special order bearing to fix it. Now we stock the bearings and fix them for people that buy them at TSC, or people that bought them from us in the past. On the ones we sold, we did not charge anyone for a repair, but since the failure was due to inadequate greasing, or at least appeared to be, we would not ask Caroni to warranty it. So we ended up not making any money on them. That being said, if a customer is really diligent and greases the bearings often, they do hold up.

    I have used Vrisimo flails for years. I sold one recently that probably had 3000 hours on it. Yes we replaced some bearings and even the rear roller over the years, but they are standard flange bearings and cheap and easy to change. So with the problems we were having on some of the Caroni's and the great luck we had with Vrisimo, we just decided to drop the Caroni and sell a commercial grade unit. Plus at about the same time TSC opened in our town and they sell Caroni. They buy in much higher volume, so our profit margin would have had to shrink. Combine all the factors, and it was time to drop Caroni.

    As far as use, the Caroni has a rather small and noisy gearbox and if used for a couple of hours it will vent a fair bit of gear lube out of the gearbox. The Rears, Dandle, Alamo, and Vrisimo mowers just make a humming sound and generally don't vent much gear lube.

    Just to be clear though, with good care, it's hard to beat a Caroni in a non-commercial application. They certainly are NOT poor qualtiy, they just aren't made for guys that mow all day every day like in orchards.

    I was in China last year and stopped by a manufacturer making flails. I can tell you they were not dynamic balancing them, or balancing them at all. They were small units with a real small diameter rotor, so that would minimize imbalance. I am curious how they will hold up, they are certainly cheap.

    With my 12' flail and a 75HP tractor, I can mow my 7 acres Pistachio orchard in about an hour. I mow about 1 inch off the ground and it looks like a park when I am done. The grass clippings are so small and chewed up, you basically can't see them, unless I get into some really tall and thick bermuda.

    Thanks for the heads up on the lubrication issue. I guess as bush hogs don't generally need any lube except for keeping the gearbox filled and the PTO greased people are not paying attention to the zerks on the flail. I have been doing it periodically but will remind myself to make it a routine each use type of greasing schedule from now on.

    I've never heard one of the higher priced flails in action but the Caroni gearbox is certainly not as loud as my BushHog SQ was. It sure does "burp" oil though.

    Any chance of making up an overflow tank for this ?
    Maybe a barb fitting to replace the filler plug (or breather, if that is where it burps), a couple of feet of plastic hose dipped into a quart or gallon oil jug.
    Clear plastic jug might be better, but that would be rev 1.1

    A couple of guys have just taken a 3 inch piece of threaded pipe and put it in between the breather cap and the gear box. Looks a little funky but apparently works fine. In my case I just let the thing bubble over and did not replace the oil (checked it but did not top off). If you leave the oil at the bottom of the allowable range it doesn't seem to "burp".

    Found this for sale. Anyone recognize it? The guy selling it had no idea what brand it is, nor how old it was......... only that it was a five footer.

    Looks a lot like an old Mott (now Alamo) design, or a brand that copied a lot from Mott. Hard to tell from the thumbnails, but it looks like a fine cut cuttershaft with a light duty rear roller. The drive pulleys are on the opposite side from my Mott super heavy duty versions. The a-frame design, body of the mower, and the pipe reinforcement on the leading edge and the back of the mower scream Mott though.

    The problem with breathers venting oil is that they are located in the wrong place , the boxes have a threaded hole available so that's where they are put . My flail mowers all have the breathers drilled into the axle tube away from the gear box . As the oil in the gearbox is constantly being thrown around by the gears it is only natural it will be thrown at the vent . With the breather in the tube it does not have that trouble as the only thing turning is the axle and that does not throw the oil around much . It would be an easy matter to fit a plug to the original vent hole and redrill and tap the tube to 1/4 NPT and refit the breather vent . It will still vent through the inner axle bearing and through the new vent location in the tube . Also a tip with greasing bearings is as i do , get off the tractor and put the back of your hand against the bearing support plate every hour . It should be luke warm but not hot , if you can't leave your hand there you must grease more frequently . Do'nt put more than 5-10 pumps into the bearings at any time as you can dislodge the grease seals with the pressure and the bearings will fail in short order as the grease will be thrown out . Tune yourself when greasing , if the slightest resistance is suddenly felt when greasing , STOP or you will blow the seal out . BPW Transpect has just come up with a heavy duty wheel bearing grease for semi trailer applications where extremely long service life is needed . It's called ECOL1 , It' a light blue colour and is designed to cope with 500,000 kilometre + change intervals . It's not available in OZ yet but maybe in the US , i will start using it in my flails as soon as it hits the shelves here . Grease is everything to a flail , as stated if they run short they will weld the bearings to the shaft in no time flat .

    Yep, after thinking about it, i decided to try them out, as the cost was not too stiff at all. I just fgotta learn how to keep it oiled properly.

    I wonder how well their chippers and backhoes work?

    Their backhoes do not have a good reputation.
