Flail Mower Thanks Leonz - Flail Mower DANDL

[Lnk]

First off, this being my first thread I started, I just want to say this place is great. After reading through 384 pages and 3839 posts, I purchased a DANDL 9 foot flail mower on ebay. Could not find any bad reviews, or good reviews, so will do that once I get it. I have to arrange shipping yet.

Here is the mower I purchased...

9' Dandl Flail Mower

That being said, a little background. My wife and I have a 21 acre homestead in Eastern TN that we are planning to move full time to next June. We have about 15 of those acres in pasture and brush hog 3-4 times a year now. I am hesitant to rotary mow near the house as we have dogs and rotary mowers throw things sometimes. :laughing: I have been looking for a solution to this, which brings me to this recent purchase. I have used a 5', a 7' and a 10' rotary, but don't care for the (winrows?) left behind from mowing. Also with the blackberries that sprout up, I would like to chop them finer than the pieces left behind by the rotary.

I know I should not have purchased the flail without testing it first. I have been assured by the seller that all works as it should, and am mechanically inclined and can repair anything that is broken within reason.

Does anyone have any information on DANDL flail mowers or links as there is just not much out there?

Thanks for any information in advance.

Hello Ink,

I want to welcome you as the newest resident member of the flail mower nations.

You can purchase many Dandl parts from Flail Master and other suppliers.
If I remember correctly Flail Master is in Tennessee as well.

New Belts-buy the green Kevlar V belts, new gear oil, remove the V belt cover and scrape out all the grass
and rubber dust use hot water and Dawn Dish soap if possible to clean it to
expose any grease fittings hidden by the dirt.

Be sure the inner bear housings do not have anything wrapped around them as the brush/junk/garbage/barbed wire will help hold in heat and cook your bearings.

Be sure to use either Dawn and hot water or good hand cleaner to clean the gearbox faces where the shaft stubs exit and check for any seepage of fresh oil.

If the gear box has a pressure vent be sure to remove it and soak it in either peroxide or alcohol after you wipe and wash it off to make sure the vent is free of debris.




NO MORE than 7 pumps of grease to start and if you see fresh grease stop no matter what and do the same with the rear roller bearing.

The open bearing from the output shaft side of the gearbox comes next and be sure to check that the shaft cannot wobble. 5 pumps of grease or until you see fresh greas and wipe up any excess grease from all the bearings as it will trap both dirt and heat.

If the snubber pulley has any wobble get a new one from flail master.
If you have a PTO shaft to use great, if not be sure to purchase one rated for your mule and you can find directions on youtube or links from the TBN attachments page showing how to do it correctly to avoid expensive damage.


Please stop and ask questions and then ask more questions to avoid problems and please post some images when you have the time.

Welcome to the Flail Mower Nations.

--------------------------------------------------------------------------------------------------------------------------------
Pronovost or not at all!!!!!!!!!!!!!!!!
Once you go flail you never go back.
I think I have lost count on how many flailmowers have to replace rotary cutters 18,400+- to go before flail mowers do it all.

Still looking for a three point hitch integral mounted Mott Interstater with the Wisconsin V-4 air cooled engine.

Thanks for the welcome. Doesn't seem like anyone has any information on these flails. I can not even find out about the company. Seems they never existed. Found reference tin a thread on another forum that says Alamo bought the company, but just speculation on someones part. At least the parts are available from Flailmaster....

Update - First thing I noticed about the mower is that it can be converted to either rotation rather easily. The PO had the flail running in tire rotation direction, and while it cut, it did not have the air flow sucking in dry leaves as I mowed. This mower has 80 stations with duckfoot blades, though the PO did also provide a bucket of spares and side cutters. I flipped the gearbox to reverse the rotation, input on front and rear of gearbox, (blades cutting opposite tire rotation) and am currently in the middle of reversing the duckfoot blades. Should be done in a couple of hours, after I finish my coffee ;-) .

Couple of observations, the deck is really heavy, approximately 3/16" thickness. Also, it has better eyesight than I, as it found some fence wire I could not even see. Also, barbed wire is more of a pain to remove than steel 2-wire barbless (whatever that really is called). Learned to be even more careful as I can not get those three hours back.

All in all very happy with the mower. Will post pictures later after mowing the new configuration...

Hello to everyone and the group... didn't need to join in to this thread other
than to reply to the Dandl questions.

Dandl was an equipment manufacturing company located at Chico, CA. Out
near the Airport if you're familiar with that area. There is no information about
what happened to Dandl, they could have been purchased or just plain went
out of business because of economic reasons.

The DANDL Flail Mower is a well constructed unit, all the generic parts are
standard sizes. I buy the triple fan belt from the Bearing Belt and Chain dealer
near my home, there are BBC stores in Chico, Woodland and Yuba City, CA.

The bearings are generic, I bought most all of them from a local supplier,
they are not cheap.

One of our units lost or sustained damage to the triple wide idle wheel, I
had to hunt around, but did find the replacement in 2016.

Getting the gearbox fixed or replaced, might be an exercise, but I've not had
to do that on any of the units we have here now. The underside where the
cutters are... the D-rings and what someone describes as the "duck-foot cutters"
are available at Tractor Supply Stores.

Grease the bearings and U-joints well, it should last you a long time and most
everything is serviceable. Sorry to see Dandl or Dandle no longer in business, but
their high quality flail mowers do live on in regular service.

cheers,

I believe they were purchased by Alamo, might have on their way out of business when that happened.

Does yours have the wierd -u- shaped "d-rings"? I have to get a few from flail master as some are bent inward and seem too loose for my liking

Thanks Skipp for the information. My deck has a few cracks that are in need of welding. The gearbox is tight, though I did have to scrape the paint off the rear PTO input in order to flip the gearbox. The PO had the flail spinning in tire travel direction. Will get more use in the months to come as we are retiring to our place in TN in early June. Any advice you can give on this flail is appreciated. Mine is a 9 foot with 80 stations and currently running scoop knives. Might switch over to y blades if I don't like the way it cuts tall green grass....

First off, the D rings come in two sizes that I know about... the 7/16" (inch) is one of the two sized
sold at Tractor Supply. I buy the larger/thicker of the two sized, but sometimes it's near impossible to
use the large size without pulling the entire O-ring down, which means pulling the rod(s) out through
the side, and that's certainly no fun. So I buy a mix of both size(s) D-rings and try to use the larger of
the two when i can fit them in/on to the O-ring. Don't let the D-rings wear down or you'll start to
hear the cutters hitting the inside of the mower itself. You'll find the steel of the D-rings is not super
strong or hard and they will wear out fairly fast, you will see a grove where the actual cutter swings.

I buy the D-rings from tractor supply, they run about $1.49 to $1.89 each depending on the size. You
can buy them on line and you can tell them you're a farm/ag and they discount the state tax if your
specific state has a high sales tax rate.

If you have decent scoop or duck foot cutters installed, the thing is a marvel to use and will clear
quite a nice and low path. All flail mowers bog down in high grass, the Dandl handles it better than
most any other. Buy the cutters with the teflon or ceramic cutting tip coating... they will actually
last more than 15 minute when you're chewing a lot of debris in a field.

Other comments, all the bearings are generic, just expensive... the main roller bearing are/were about
near $200 to $300 each last time I had to buy one. Applied Technology in Sacramento is one store
of a very large company (probably one in your part of the country) also I'm sure selling on line. They
can supply all the bearings. So grease well the bearings and u-joint knuckles...

I'm sure the unit will sustain cracks and damage after this many decades of use... just weld them up
properly and get on with things. I have three of the same model Dandl... the are often found second
hand and as in my case, missing the rods, O-rings, D-rings and cutters... But those are parts that are
normally replaced so that's not really rocket science once you get things under control. OK, again I
hope this helps a little.

Just saw a Dandl with the same gear box as yours. While I have an 8ft Vrisimo, the gear box (this would be about a 1975 construction) looks identical, absent the rear take-off. I need to get a new gear box, but Vrisimo says "obsolete" and that I have to get a different gear box that requires a shaft offset and u-joint, and about $2000 in re-fabrication.

Any information on this Dandl gear box would be helpful. The box on the mower I saw says "Dandl" on the casting.

Hi John,

If you have the old gear box, any decent machine shop should be able to repair or even make you a new
one. Might not be cheap... you could try finding a gear box made for some other piece of equipment, it's
not that uncommon of a gear box that you couldn't find similar units made for other brands. We have
two or three really high quality and great service machine and fabrication shops in the Sacramento
CA area where I live. If you're down in Fresno, you probably have similar services available. I serviced my
Dandl today and noticed the only thing I couldn't easily find without a lot of work are the large rubber
shock/vibration units. Even if I couldn't find the originals, I could make something fit and work well.

Hope some of the above helps you...

cheers,

thanks for the reply, and the good wishes. A bolt in would be first choice. Yes, plenty of machine shops but trying to avoid that route. Not so easy moving a 2000lb mower around.

Am somewhat thinking that I should have Vrisimo take it in and remount the side pulleys and belts, along with a new gear box, and turn it into a low-profile for almonds. It's such a beast, 1/2" rolled steel all around. They aren't made like this anymore.

Hello, I just went through the exact same situation with my old bush Hog FM188/ ford 917. The rotor was spinning the same direction as the tires and the blades where on backwards and all I did was reverse the blades because you want the rotor spinning the same direction of your tires so the blades create a suction and lift the grass up that you flattened with your tractor tires. Why did you flip your gearbox over instead of flipping the blades?


Blades installed backwards


Blades installed the correct direction.

If I'm wrong about your brand of flail or missing something others please chime in.

Generally speaking, for flail mowing in agriculture, the blades should be pointing forward, and the drum spinning forward (opposite of the tire direction). This helps suck debris up and cut things multiple times, as well as smooth out the ground after the pass. When dealing with growing plant material, that's the only way to do it. Shredders go the opposite--but they have heavy teeth or shanks that drag along the ground behind the drum and lift the material up so it gets into the path of the hammer (different cutters as this is typically heavy or woody material). The shanks help lift the woody material up far enough so when it gets hammered, it kicks the material up and around again, and may blast it a second time if it is still big enough. Most units are single purpose. FM's can be wider for the same horsepower. There are limits on blades, spinning mass, construction of the housing, etc. Big Shredders are extra massive as they have to deal with wood up to a couple inches thick. They also have a taller opening up front so the woody material can pass under without dragging.

Yours may be a dual unit for either light-duty shredding or mowing. Does it have the shanks, or a bar to allow shanks to be installed?

Best,

John

My blades were on correctly for the tire rotation direction but wanted to try to see the difference with the opposite rotation. Here is a picture of the blades while in the process of reversing them.


Changing rotor direction on this flail is a 10 minuted job. Remove 4 mounting bolt from under the gearbox mounting plate, slide the gearbox off the drive shaft, flip and reinstall. Just have to swap the gearbox breather with the plug on the bottom.

The mower cuts great but am switching to the Y blades from Flail Master as I would like to cut more than grass. Also reversing direction would not require flipping blades. The mower is 9' and has 60 stations.

Jwedd and Ink, thanks for the info, funny thing is that I'm doing just the opposite, switching back to the scoop blades because my field is not that thick, just ordered the standard scoop knives from flail-master should be here next week. The y-knives left a lot of fox tails so I need a closer cut.
