OT: Lawnmower operator presence control
Hi folks,
I'm hoping someone here can answer a legal question for me, as I can't
find the answer online. A friend told me recently that if you have a
lawnmower, and pay someone to use it, it must be fitted with an operator
presence control. That is, one of those levers you have to hold onto,
and if you let go of it the engine stops. Personally I find them an
annoyance. Does anyone know if this is true?
Many thanks,
Chris

I know that all new electric mowers are now required to have such
devices, but I haven't heard anything similar pertaining to petrol
mowers.
BS EN 836:1997 states that "For pedestrian controlled machines the
control handle should automatically stop blade rotation when the
operator's hands are removed. " - but that's currently just a
standard.
I suspect if you're paying someone to mow your lawn then you're
employing them - and in the event of an accident you might find
yourself liable for allsorts.

I guess you might get some pertinent advice from a mower specialist,
such as the one below ( who mention Hand-Arm & Body Vibration Risk
Assesment (sic), of all things ).
http://www.psmlawnmowers.co.uk/
Personally I tend to 'semi-deactivate' the "dead man's handle" with a
strip of aluminium bent over the handle in a figure of 9 fashion. It
can be flicked off quickly and easily yet still enables the mower to
be left running while I empty the grassbox.

I think electric mowers have always been designed this way, as you can
stop and start them with a switch. But with a petrol mower it's much
more of a nuisance because of the extra effort required to start the
engine again.

Indeed. So machine built since 1997 must have this feature. But that
alone doesn't mean that older machines are illegal to use.

For the time being, it is just a matter of curiousity, as we cut the
grass ourselves. But I'm interested to know if it's true, as I was told
that it was the reason for many older machines being retired from local
authorities and cricket clubs, etc.
In some ways, it would seem odd if it was a legal requirement. After
all, there's no such device on a tractor, which could potentially cause
much more damage if it went astray.
Personally I find it annoying having to hold onto that lever.
Best wishes,
Chris

Is it a 'must' or a 'should'? I thought it was only applicable if you
wanted to conform to the standard - I'm not sure it's a requirement?

I'm inclined to think it's more about which bored bureaucrat could be

The better ones have a bar that sits above the handle - at least you
then have the weight of your hands in play.
Where I see models fitted with a dead man's handle at the local tip,
there's nearly always a plant tie attached to the handle - so I think
it's a fairly common annoyance.

It would all depend on whether the relevant standards/regulations are being
applied retrospectively (ie. to machines built prior to the introduction of
whatever the latest deskmonkey has thought up).
The best place to get an answer would be your local H&S office. As much as
people hate them, they can be quite handy for finding out such things.

I'll see if I can find a contact number and give them a call. If I find
out the answer, I'll post it here.

They makers of mine thoughtfully included a couple of tie wrap like
things that could be fitted around the push handle and hold the
cut-out bar in. No way do I stop one of those things until the job
is done. Can't understand why the pull start on the moped sized
engine takes more effort than on my 18hp Briggs and Stratton powered
hydraulic concrete breaker. When the cord snaps the assembly will be
removed and a battery electric drill & socket used on the flywheel
nut.
Don't tell them about spring ejected chuck keys for the lathe.

Whether it is obligatory to have such a cut-out I don't know. What is fairly
certain is that should you employ somebody to use that mower with the
cut-out deliberately disabled, then you would be guilty of wilful neglect of
that person's safety and therefore liable to pay compensation in the event
of injury.
Like most people I regard it as a damn nuisance and tie it up with a plant
tie. The one on my hedge trimmer is even worse because it incorporates a
brake with a powerful spring, making it ridiulously heavy to hold up, and
tiring on the fingers to clench both triggers.

What I was talking about is a mower which never had one in the first
place. Anyway, it's just a matter of curiousity for the moment. It's
hypothetical.

While I have yet to contact the local H. & S. office (I do intend to), I
came across something interesting today. I was looking at a brochure for
the latest Dennis lawnmowers. None of their most expensive machines have
an operator presence control, but the cheaper ones do.
Presumably this means that it is not a legal requirement. It also
suggests that professional groundsmen know that the feature is annoying!

I'm guessing the more expensive ones require you to pull a lever to engage
the blade though...
It's not a requirement for the operator presence control to stop the engine.
It just has to stop any cutting blades. You can buy Honda mowers that work
by disengaging drive to the blade, but they are more expensive, as they
obviously require a good few more components.

On cheaper mowers, releasing the device
stops the engine.
On better mowers, releasing the device
disengages the engine from the blade.

Thanks for suggesting that I contact the HSE. I have now had a response
from them, and I thought I would share it here for the benefit of others.
There is no specific legal requirement in the UK that a lawnmower be
fitted with an operator presence control. However they also referred me
to the Provision and Use of Work Equipment Regulations 1998. The gist of
these regulations is that the employer must select equipment with care
in order to reduce or eliminate risks to the health and safety of their
employees.
Based on these regulations, a good lawyer could probably construct an
argument either for or against an operator presence control. It could be
argued that it has few negative effects, and therefore is a worthwhile
added safety feature. But it could alternatively be argued (in my view
more convincingly) that the feature is a nuisance, increases operator
fatigue, provides a false sense of security, is very rarely used to stop
the engine for safety reasons, and is a feature commonly omitted from
larger, more dangerous machines.
In the end I am left with the gut feeling that it is much more important
for the employer to choose his operator carefully than to ensure his
machine is fitted with an operator presence control. While the following
quote is a bit frivolous, I believe it's appropriate here:
"You can't idiot proof anything; every time you try, they just make
better idiots."
I forget who the quote comes from.
Thanks for the advice.

Chris

I'm still waiting for MY lawnmower to come back after the gearbox associated
with the 'operator presence control' failed after 2 months ( 5 or 6 uses ).
It's taken 10 weeks so far and no sign of it coming back soon so I've asked
the Credit Card company to refund us.
I think I've said before about 90% of equipment failures being due to the
built in test equipment that is supposed to make things more reliable. Strip
all the crap, keep it simple and you will be much better of :)
And if anybody is thinking about a new lawnmower - don't bother with Mowerland :(

Just out of interest, what is the make and model of your mower?
Some pieces of electronics have made machines more reliable during their
intended lifetimes. Modern car engines start more reliably in cold
weather than most old engines, for example. But all added complexity,
especially electronics, compromises the long term maintainability of a
product.
In 50 years time, are people going to be collecting the lawnmowers and
engines made today? I think few people will be interested, because they
aren't the exemplary pieces of workmanship that they used to be.

In this case I think the continual stopping and starting of the motor has
stressed the 90deg gearbox that takes power from the engine to drive the rear
wheel. It had just seized solid, and one would have to dismantle the 'operator
presence control' to get the belt off to make it a simple push along.
On the aspect of 'ealth and safety' - I think I will probably do more damage
to my back having to restart the engine every time a empty the basket. Which
can be 30 or 40 times each session :(

Examples of how not to do things in future :)

Looks typical of so many modern mowers.

Well, I certainly hope that will be the case. But it'll require buyers
who demand better quality and manufacturers who have the skill to
provide it.

For the record, I'm going to note here that I was mistaken. The most
expensive machines do have an operator presence control.
Sad, really, as it'll make them a pain to use.
