Hi my name is Alistair Gill and I'm the Senior Quality Engineer at Allett Mowers. Today I'd like
to talk to you about our Liberty 43 product. This is our best-selling domestic homeowner product.
It's a 43 centimetre or 17-inch cylinder mower. We actually sell three models in the Liberty range;
a Liberty 30, Liberty 35 or this the Liberty 43. The Liberty 43 is good for lawn sizes of
up to about 280 square metres and it takes all of the cartridges in the Allett range.
The benefit of this product is that it's powered by Lithium-Ion so I'm not tethered
to an electrical cable or I'm not relying on using petrol in an engine. The Liberty 43
is a self-propelled cylinder mower that means I'm not having to expend energy to push it around the
battery and the mower do all the work for me. Some of the big benefits of using Lithium-Ion battery
in a cylinder mower are that there's no emissions at the point of use. I'm not breathing in those
small particulate matters that are particularly bad for health. I'm surrounded here by lots of
neighbours so if I'm mowing early in the morning on a Sunday I'm not disturbing them it's nice and
quiet. It's a nice and lightweight machine for getting in and out of the garage or the shed.
I'm not reliant on storing petrol, I'm not likely to damage the lawn if I spill petrol, I'm not
filling up an engine, I'm also not trailing cables round as it would be with a mains powered mower.
It's a push button start so I'm not having to pull cords to get a petrol engine going. I'm not having
to service an engine yearly the battery and the power head do all of the work for me. For more
information on the benefits of battery power please check out our other video on YouTube.
What are the benefits of a cylinder mower? As the machine moves forward across the turf
the cylinder gathers the grass blades together and then cleanly cuts them against the bottom blade so
in effect we get a clean scissor-like cut of the grass rather than the more sort of machete action
that you would get with a rotary mower. Now why is that important? It makes sure that the
cut is clean as I've said and that helps to ensure the grass is healthy,
you're less likely to get disease in the lawn and you lose less moisture through
the grass blade. Our cylinder mowers have a front and rear roller and that's great
because it means that we get no wheel marks on the lawn and it gives that better striped finish.
We also get a better stripe across the width of the mower because there are no wheels.
We can also use all of the six cartridges in the machine which reduces the amount of chemicals
we need to use on the lawn in fact we don't need to use any chemicals if we don't want to.
It's a nice and light machine; the Liberty 43 weighs 38.5 kilos so that is slightly lighter
than our Kensington petrol equivalent so if that's something that you're concerned about
the Liberty is the lighter model. So the Liberty 43 comes with a 62 litre grass box
these are made from polypropylene. They're nice and sturdy, impact resistant, they're
not going to get damaged, they're not going to rust, no corrosion problems with these.
This fits simply onto the grass box loop at the front of the machine like so,
nice and simple the one thing to be aware of with the grass box it is 62 liters
but you don't want to fill it too much because as the grass box fills
it actually pushes down on the front roller and that can alter the height of cut so you
just need to periodically empty that into your compost bin or green bin.
The Liberty 43 has a steel zinc plated front roller this runs on bearings at both ends which
makes it accurate and is it's long lasting. The front roller is what controls the height of cut on
this machine so if I turn it around for you to see I have a dial on the back of the chassis and as we
rotate this the front roller pivots and that's what changes the height of cut. We have a dial
on the side this ranges from 'S' a height of cut of 6.5 mil up to '4' which is a height of 32 mil.
If you look to the side we have the heights of cut of each number displayed for you.
The height of change mechanism on the Liberty 43 is stepless. The benefit of that is you can set
the height of cut anywhere between any of these positions so if you're scarifying and setting two
is too deep and setting three isn't quite enough then you can set that wherever you need to. On
the Liberty 30 or 35 it's a discrete height of cut change so you can only go to the specified levels.
Just behind the front roller we have a grass rake the purpose of that is to stand up any
lateral grass growth or any weeds so that they're delivered to the bottom blade nice
and vertical for a clean cu. The grass rake is adjustable and to find out how to do that check
out our other video link above. The Liberty 43 also comes with an auxiliary wheel kit this is
perfect for those times where you've been away and the grass has got a little bit too long.
Cylinder mowers are very good for cutting short grass even shorter but if it's too long what
we recommend is that you remove the front roller and attach the auxiliary wheel kit.
That just raises the height of cut to allow that longer grass to be cut cleanly. For information on
how to fit the auxiliary wheel kit check out our other video link above. The Liberty 43 comes with
a six bladed cylinder whereas the Liberty 30 and 35 come with a five blade cylinder.
The six blade cylinder in this machine delivers 79 cuts per metre however we do recommend that
if you're cutting at a height of cut below 20 mil that you consider the 10 blade cartridge.
A six blade cartridge can be prone to washboarding at shorter heights of cut the extra blades on the
10 blade will reduce that issue for you and you get a nice clean crisp fine cut.
To achieve the best quality of cut with our cylinder mower we recommend that before you use it
you do the paper test this ensures that the cylinder to bottom blade contact is consistent
all the way across. If it's cutting paper cleanly it will be cutting the grass cleanly
and that ensures that you get a clean cut and a nice healthy sward. The benefit of the Liberty 43
is that it takes the entire range of Allett cartridges. It's more than just a lawnmower
it's a complete turf cultivation machine so all six of the cartridges will fit the Liberty 43.
Just quickly we have the 10 bladed cylinder. the verticutter, the scarifier, the dethatcher, the
aerator and the lawn brush. So those tools can be used for various cultural practices on the lawn.
They're interchangeable into the machine it only takes a couple of minutes to take the
cylinder out and insert a cartridge. They take up much less room in the shed or the garage
if you're trying to store these if you had a verticut machine and a scarifier
machine and an aerator machine that becomes cumbersome to store. The nice thing with the
Allett cartridges and the Allett cartridge stands is that it takes up much less room.
We do have a further video on YouTube where you can learn more about the Allett range of lawn care
cartridges. All of the Liberty models in the range use a 40 volt, 4 amp hour greenworks battery.
Fully charged that'll give you about 30 to 40 minutes mowing time and it's really easy
to remove. There's a little clip on the top you press that down and pulls out like so.
There's also when you look at the power head a safety key that's important if you've got
children around that you don't leave that in the machine that's just a safety feature so
they don't get hurt. The benefits of battery as we've discussed are that it's nice and quiet so
I'm not disturbing my neighbours when I'm mowing, it's nice and light, I'm not having to go to the
petrol station to get fuel and I'm not managing cords around the garden. The greenworks battery
can also be used in other products around the garden so hedge trimmers, strimmers, chainsaws,
leaf blowers etc so that that one product helps us to keep the entire garden tidy.
The battery itself takes about one hour 30 to charge so it's nice to have a couple of these
so that if it does run out you can just get the other one put it in the machine and carry
on mowing and then you're not interrupted. When it comes to lithium-ion technology some people
are concerned about the life of a battery this battery can be discharged 1800 times and after
that it's lost only 15% of its capacity so you've still got 85% capacity after 1800 discharges.
The battery has four LED's to indicate the charge status. You just simply press this button here
and they will illuminate to show how charged the battery is. The Liberty 43 has a double section
steel rear roller with a differential inside. That really is the stripe maker. That's what
leaves the defined Allett stripe on the lawn that's so desirable. The double section helps
with the differential when you come to turn at the end of a run especially now in the autumn
the grass is a little bit wet or the soil is wet we don't want to scuff and damage the turf
and it also helps keep the stripes straight. So the stripes that you can see on the camera,
the darker stripes are running towards the camera, the light grass coming towards myself. We'll have
a look at the handlebars on the Liberty 43 now. They're slightly taller on this machine
and they come with this nice padded comfort grip. The operator controls are very simple
and nice to use. We have a simple speed control which we can rotate to adjust our forward speed.
There's a safety red button and red lever which operate the cylinder and then we have a bail
bar because this is a self-propelled machine so that engages the roller drive to move forwards.
The handlebars as I said are slightly taller but they're very simple to fold that makes it
nice and easy to lift the machine and store it in the garage. So in summary, the Liberty 43
is our best-selling homeowner product. It's a 17-inch or 43 centimetre cylinder mower.
It's clean, green and very quiet. It uses the Lithium Ion battery power that we talked about.
The advantages of that is it uses all of the six cartridges in the range so it's more than just a
machine it's a whole lawn cultivation system. So if you're after that beautiful striped lawn that
so many people find desirable I would highly recommend the Allett Liberty 43. Thank you
