Flail Mower Let's talk flail mowers

[Fallon]

You have 2 pumps on your L4060HST. One for your Power steering and one for your Implements.The manufacturer adds them together to give you give you "Total Hydraulic Flow" of 14.1 GPM. Considerably less than the 21 GPM you mentioned. In addition, you are only going to get the flow from the Implements pump of 9.4 GPM. See attached from the Kabota site:

I definitely know that. Never bothered to look to see if it's a 2 chamber pump or a 1 chamber with a flow divider, but the effect is the same.

I was just pointing out what HP would be transferred to that flail based on common pressures & the stated GPM range.

I run a hydraulic SSQA on the L4060 & it has about half the HP (seat of the pants, a bit more calculated) that the PTO PHD on my old L3200. Other factors make it better over all (downpressure & ease of hookup), but it has way less power. Most CUTs can put out under 15hp at best via hydraulics.

Power is rate of doing work, right ?
Dimensions of force x distance / time
Without deriving this I'll state that in hydraulic systems Flow x pressure is also "rate of doing work".
For THIS application flow rate is probably required to get the required rotor speed, PRESSURE may only be needed if/when the mower meets a heavy load.

It seems to me that if PRESSURE isn't critical it could be sacrificed for flow, i.e. double the flow while halving the pressure (not quite, there would be losses).


Kwiz kwestion;
How could you do that ? <smirk>

I can say that with proof; until I fixed the wheels and bearings on my fathers Lawn Genie Pic Up mower we had that type of wheel and so called bearing and they do not last very long and the wheel becomes damaged and the only thing salvageable is the tire.

The 13.8 horsepower engine is not enough for a 48 inch flail mower either. My Lawn Genie Pick Up Mower has an original 16 horse power Industrial/Commercial Briggs & Stratton engine from 1980.

You can purchase motorized flail mowers with rear mounted wheels but they will have no rear roller as they have a worm screw adjustment for height control and they have to be imported.

I never recommended the product. It was posted as an "IDEA" for those w/o tractors.

I'll learn from this though.

........................................13.5 HP seem a bit much for only 48" too, given that it isn't self propelled - garden tractors cut wider than that with similar HP.

You are comparing power requirement of regular lawnmower to a flail mower!

:laughing:

I wonder if anyone has any experience or thoughts about this flail mower. It would be perfect for getting into all the hard to clean up areas of our property.

If you want to do "down" banks of greater than 15 degrees and not have one tire over the bank, you really need one that has the gearbox on the outboard of the belts rather than the inboard AND when swung completely to the right it should clear your tires. Otherwise you won't be able to get the full downward motion.

The videos show them doing banks but notice that right tires are always on the down slope.

Similar to this one:



(Edit) - otherwise the one you linked to will work great for level ground.

Have one similar to the one linking. It does swing out far enough to do the steep banks. Mine is around six ft

Anyone figure out the "BEST" replacement belts for the Caroni 1900 ?
It seems I bought a set of 3 spares when I bought the mower a dozen or so years ago, now that I need them I have discovered that they are 48 inch ones and WAY too long.

Is it worth buying the fancy (kevlar) ones ?

I use a similar model with my L6060. It's a 72" Maschio Girafetta offset flail



It cuts banks with the right tire on the level as shown:



The trade off is the cutting path on the level with the head fully retracted is not centered with the tire track and the left tire rolls over an uncut surface. This forces you to mow in only one direction when on level ground. There is a model which does center but the slope cutting width is reduced.
