Hi, anyone know anything about them?

Are they any good or a bit Mickey Mouse?

My neighbour has one,he parks it in my shed when he's not using it,or repairing it!
Wheels have a habit of dropping off,especially when being tow through the village.
Sh*ts it self if it looks at long grass,strips belts,then its a pita to start when its hot.
The wheels stick out the side and run down too much grass,so we moved them so they run behind the mower which then makes it heavy to couple up,as it not balanced so we now have put a jockey wheel on it now which helps,but at least now it doesn't run the grass down.
Its ok if the grass is kept short tho

Like your wheel mod. I used a Wessex with a big V-twin motor that at least had enough power to cut grass. Needed a manual geabox with a proper low speed ratio on the quad, was my finding then.

The Mcormick reverse steer tractor and flail topper I bought, confined the Wessex to the shed until I flogged it.

I've never known anything from kellfri to be worth having.
IMO buy a better quality used one and spend some ££ on new flails, belts, bearings etc.

My mate swears by Port Agric ones with Kohler engines on the path contracting job. Don't think they make them any more but you see them advertised from time to time

That's a bit harsh. I've got a set of their pallet forks. They're fine, seem strong enough but (obviously) there are no moving parts to go wrong.

They are good, we have started making them from the original drawings. They beat all others hands down. We use a flywheel and a single 4ft rotor. Made from 4mm folded steel. Fleming started making them when Colin port stopped but they made them to a price and no where near as solid. Also use a nice Kawasaki or loncin engine on them now as Kohler don't meet regs.

I loved the sound of the V Twin motor on mine... Music to my ears.

Possibly why I have had 4 V-twin motorbikes over the years...

They did sound great the old Kohler engines. Powerful as well, the new 14hp loncin vtwin and 18hp Kawasaki vtwin sound throaty too. Also deliver a really good power. Down side is their cost. Compared to a single cylinder briggs they are expensive. But worth it as they are a premium product that'll last 25 years.

I have tried using these towed flails designed for ATV's and I class them as toys for regular trimming in large gardens or orchards, not for farm work. Show them any grass over 6 inches tall and they stall. If McConnell recommend 40 hp for their 1.5 metre wide flail, how can Kellfri possibly do the same job with 18 hp?

If you look at them, they are all running y flails and not hammers, they require half the amount of power a hammer requires, don't disagree about them not being suitable for really long grass though. The portagri one does have a 10kg fly wheel to give it innertia also it's a rotary. Plenty of power for the width of cut. Also, rotor speed, to double the speed you have to qube the power, hedge cutter heads require a lot of power as they are spinning really fast, small diameter rotor also requires more power per foot.

Sorry to correct you, but according to their promo website, Kellfri mowers are supplied as standard with hammer type flails. Y flails are available as an option at extra cost. Don't agree either with your statement that small rotors require more power per foot as larger rotors are heavier and have a higher tip speed so need more power to drive them. Typically hedge cutters run at 3000 rpm but reduce speed to 2400 rpm when cutting grass. I fully accept that Port Agri is decent kit, but the OP was asking about Kellfri.

Ping me your email, I’ll send you all our calculations for our machines. We manufacture flail rotors and toppers. [emoji106]

100% accurate

I'm on my fourth set of drive belts this season.
I'm asking too much of a light weight piece of equipment I know, but where I am in the fens on black peat, I get a few days rain when I can't cut and the stuff has grown 3 foot. I'm not joking.
Still I can't afford anything more powerful just now. So I'll keep on crawling along at a snail's pace and putting new belts on it every ten hours or so.

Your post made me cry/laugh but I'm glad it's not just me. I've got the wheels behind and I can't get it off the quad and the belts shred at the slightest bit of tough grass. The Kelfri flail is a fraction of the price of real kit but is it worth the aggravation?

 

[PostHarvest]

This morning I was cutting brambles, nettles and other rubbish with my second hand Bomford Bandit flail behind a 50 year old MF135. If I could drive through it, it cut it. Belts survived OK. Where can I get power steering and power shift for the 135?

If that's grown in 'a few days' then the ground is far too fertile to not be grazed!

Mixed agroforestry attempt, sheep, pigs, cattle would make chippings out the 2000 trees I planted by hand

Thought about ducks, geese or the Norfolk Bronze but so far trying to grow veg, fruit and herbs without spraying.

Yes I'm a newbie, drowning in weeds and all my neighbours are dying laughing .

Still my wild cherry has been pretty good this year.

(Oh gawd, feel like I'm stood naked in public, I'm usually pretty vague about what I'm up to so if it doesn't pan out I can duck for cover, why am I telling you the truth? Be nice ok).

Don't worry I've had plenty of people tell me the land is too fertile to 'waste' like I'm 'wasting' it. Even a random neighbour I'd never met before who collared me in the lane while I was out walking minding my own business.

I'm doing things differently, and I've been surprised how nervous/irritated that makes people. I don't take much notice, it's too good good watching the soil come back to life.

Now anyone wanna take this Kelfri flail of me?

How much you want for the MF135 and the Bomford Bandit, and can you deliver to Norfolk? If I could afford it I'd take it today!

Cutting through brambles?
