Flail Mower Let's talk flail mowers

   / Let's talk flail mowers #5,061  
I first posted on the “Buying Advice” forum since I am looking for both a tractor and flail. Most of the responses there dealt with the tractor aspect, with only generalities about flail mowers. So I want to come here for more specific recommendations on flail mowers. Apologies to anyone who is rereading my background.

I am a complete newbie, never even owned a riding mower. My wife and I bought a 9 acre spread with house and pole barn 20 years ago as a retirement home. We rented out the house and paid someone to bush-hog the half of the fields twice a year for $500 a pop. Two other fields were being hayed by a neighbor, and another neighbor fenced in another pasture for their cow. Sometimes I would cut the sections of lawn with my push mower (4+ hours), sometimes hire someone. But now the cow is gone, the first neighbor is talking about moving further south, and we are in the house. I figure it is time for me to do the mowing.

The lawn is by no means pristine, so I'm hoping that I can get by doing most of it with the flail instead of using a regular mower, and don't want to spend the close-to-$2K for a belly mower. The fields are pretty clear, both rolling and flat, nowhere that I would term steep. Most of the fields have some trees, but not many. We've always had a bunch of honey locust saplings sprouting up which we then have to deal with by hand, so I figure more frequent mowing will help stop that. I'm not going to making new trails, pretty much maintaining the fields, so I shouldn't need anything heavy duty.

The grass is pretty high right now – was last bush-hogged 2 months ago.

My wife was the one who first heard about flail mowers and they really appeal to us. I've been doing some research, found this forum, and have learned a lot. At this point I am thinking about either a Kubota B2601 or B2650 (PTO = 19.5 for either) with a FEL. Now I am leaning toward the smaller, less expensive tractor. For flails, I had been thinking about a WoodMaxx, but they are backed up on delivery. Some people in the forum like the Caroni flail a lot, plus it is in stock. The question is what width to go for, whether the 4’ version or the 5’ one (can anyone tell me why the smaller one is more expensive at Agri Supply?!?). Also given my PTO, I’d be going for the TL version. Leonz said to another poster to go with the 4’.

Given my application, I'm still unsure of which flail blades would be best. WoodMaxx says to use the duckfoot blades for clearing saplings (1" diameter or less), and the Y-blades for grasses, but I thought I read here that the duckfoot blades give a nice appearance to lawns. Does it make sense to spring for both set of knifes, based on the application?

Any comments, advice, and/or suggestions would all be appreciated. Now I need to convince my wife that spending $20K+- on the pair is money well spent.
If you can lift it, you can spin it. You might have to go slow if you are short on power, but you'll get there. Just make sure the flail is light enough for your 3pt. It's best to stay in the ballpark on powe. But personnsly I like a wide mower. Going slow is a much smoother ride & easier on me & the machine.

My old Ford 917 with side slicers did ok enough on brush. If you are only going to mow them once then stay up on things so they dont get bad again you are probably fine with side slicers. Side slicers give a great cut quality & finish.

... I ordered it on Monday, April 23rd and it arrived on Friday May the 8th. That is four full business weeks which falls into what I was told when I ordered it , but it just seems a tad long, especially when they said it takes 7-10 days just to process the order.

I work in technology for a finance company. We have to do all sorts of calculations based on weekdays, working days w/ holidays included, days that the markets are open, etc..., etc..., and I'm trying to figure out how 15 straight calendar days (incl. weekends) can in any way be 4 'business' weeks. Seems to me that 7 business days processing time would've been Wed., May 2nd. Assuming it shipped that day, that was 4 business days 'in transit' if you received it the following Tuesday (2 weeks and a day after ordering)?

Maybe it just seemed like 4 weeks? ;D

No it seemed like six months. :laughing:

I'm sorry , that was a typo. It arrived Friday May the 18th. Good catch.

I know what 6 months feels like. Ordered mine in November. It arrived last Wednesday. 5/16/2018.

Today I went back to the dealer and put a deposit on a Kubota B2650, then came home and ordered a 5 Caroni from Agri Supply. Tractor is supposed to arrive on Tuesday, and the Caroni is scheduled to ship the same day, so I should see it either Wednesday or Thursday. The Caroni could have come earlier, but I need the tractor to move it down the driveway. (WoodMaxx is quoting mid-Sept for delivery of their 5')

So I need both gear oil and grease gun + grease before I can use the Caroni. Anyone have suggestions on brands? Some grease guns have a rigid tube, others a flexible one. I assume flexible is preferred. Is it better to get synthetic grease?
 
   / Let's talk flail mowers #5,066  
Dealer should sort out the gear oil. I prefer the flexible grease guns, swear by lock-n-lube attachment, makes the whole process a lot less messy.

You'll enjoy the 5' Caroni, have the same one on our Ford and works great.

Gear oil you can get a Walmart. Wait until you get manual to buy it. Unless someone can tell what is recommended.
Check out pistol grip grease gun. I have a Lincoln and the cheaper model. Both work well.
 
   / Let's talk flail mowers #5,068  
If you're already invested in a cordless tool system (Dewalt, Milwaukee, etc...), see if they make a grease gun. Most of them get pretty good reviews. I recently grabbed the Dewalt 18v (tool only) for $139 off Amazon, $60 less than the 20v model. Get the Lock n Lube, too.
 
   / Let's talk flail mowers #5,069  
Lock 'n Lube is worth it- it's a real improvement over the standard tip that's either too loose or needs to be loosened by unscrewing it before it'll come off the nipple. Power grease gun for home use? Not needed. A good manual Lincoln is fine. I have both lever action and pistol grip type guns and prefer the pistol grip with hose for most things as it's more versatile. Synthetic grease and gear oil is not needed for tractors and equipment.

I also have the LockNLube coupler:

My favorite grease gun is a 10,000 psi lever with the the rigid tube replaced by a hose:

I recently added a two foot long extension to the hose. :thumbsup:

Hello Jerik,

Welcome to the forum, If you can find an Alemite grease gun they are of a very high quality manufacture.

Greases and oils must meet the American Petroleum Institute specifications to be sold so you have no worries there.

The red high temperature grease is a very good grease to use so you will not go wrong there.

I you can find the Kendall squirt bottles of 90 weight gear oil it will be fine to use that in your gear box.

Did you order the dipstick extension kit for the flail mower gearbox?

Having a grease gun with the flexible hose and the loc-in-lube will help you as the spiders/crosses/universal joints you will be much better off with the grease hose as you need to the flexibility to reach them if the PTO shaft is left connected all the time.

Just remember that you do not have to grease the universal joints at every use, the flail mower rotor bearings should greased every 6-8 hours depending on how heavy the brush is and the grease rear roller at every mowing and be sure to check the mounting bolts for the rear roller mounting side plates at every use. if they are lose please use some blue loctite to hold the bolts in place. When using the blue loctite you can pour a line of loctite on the length of the bolt to secure it. Just be sure not to over tighten the bolts.

If you are clearing tall brush you need to check the interior of the flail mower(under the flail mower shroud) to be sure that there is nothing wrapped around the flail mower rotor bearing hubs as any brush will hold the heat in and heat up the grease and ruin the flail mower rotor bearings.

Do not hesitate to ask questions as we can and will help you.

Thanks for your info. Dipstick extension kit? I don't recall hearing about it, so no. I don't see anything like that on the Agri Supply website. What does it do and where do I find it?

I also just ordered the Lincoln 1134 grease gun recommended by ronjhall and the LockNLube recommended by ericm and others, and a tube of Lucas Oil 10301 Heavy Duty Grease. Is that grease OK? And it sounds like I should pick up some loctite too.

Frequent greasing with the "wrong" grease is orders of magnitude better than infrequent greasing with the right grease. Dont over grease so you blow out the seals (a couple pumps is generally all you need, or refer to the owners manual).

Some grease types aren't compatible, but if you pick one & stick with it, that a moot problem.

First I have a question for those of you with side shift flails. Do you put any grease on the shift rails? I feel like I should be putting some type of lubricant on them, but there was nothing in the (terrible) caroni instructions.

Second I just completed my first full mow of the year with my TM1900. I don't know the acreage but it ended up being right at five hours on the tractor. Based on it I have a couple thoughts for people looking at a similar setup.
-The side shift is NICE, but because of Caroni's design you can't fully lift the mower with the PTO connected. If you lift too much the side shift rails will snap the PTO. This isn't a problem unless you constantly need to raise the mower a lot. I can raise the flail high enough for road transportation, so it's fine for me. I do need to unhook the PTO to load the tractor onto my trailer.
-I was worried that my Kubota L3901 wasn't powerful/big enough for the TM1900. It has more than enough power for my knee-high grass (not once did I bog down the tractor, and I was going as fast as I wanted to). If I was plowing through really tall weeds I'm sure I'd need to slow down. The flail is a lot of weight on the back, but not too much. I did need to put my wheels out as far as they'd go to keep things from feeling 'tippy,' and as soon as my buddy has some spare time I'm getting the rear tires filled.

I just ran into issues with my Peruzzo not wanting to side shift. Some lube got it sliding properly.

I tend to use a dry lube for this type of stuff. Either a teflon spray or motorcycle chain wax. Oil or grease will be covered in dust & grit in seconds. I have to scrape piles of dust & grass off those rails every day just due to how things settle ontop of the mower. So far the chain wax doesnt make things stick.

Peruzzo appears to use stainless or chromed rod for the side shift rails. Hydraulic cylinder shaft that they weld on the bottom it looks like.

The bushing on my Woodmaxx are nylon. If Caroni's are similar I would say no lube. Keep shafts clean if that is possible.
 
   / Let's talk flail mowers #5,079  
If the shafts getting dirty is a concern, why don't they cover them with something like a shock boot to keep any crud off of them?

At least on my Peruzzo, the bushings only cover 3/4 of the guide rod, so sealing anything up all the way isnt really possible. It would make cleaning things way harder. Given how grass & dirt gets packed everywhere already I know it would end up packed inside any boots unless you could seal both ends & the bottom well.
