-Neil from Messick's here.
We're out today with two track loaders
at Kubota SVL75 and a Bobcat T320.
We're going to do a short demonstration today
on some of the differences between electronic pilot controls
and hydraulic over hydraulic pilot controls.
When you're sitting in the seats of these machines
the joysticks look very similar to each other
but you can see that there is some real mechanical differences
in the way that they work.
Take a quick walk around here with me today
and we'll show you some of the differences between
how these machines operate.
Now let me be very, very clear that this is not intended to be
a competitive comparison between these two machines.
When you're in our situation and you have the opportunity
to go to manufacture training events and that kind of stuff
where we can have half a dozen competitive machines
lined up side by side and you can jump
from the seat of one machine to the other.
You'll start to notice some differences
between how machines operate.
We're going to go through we're going to do a demonstration
of how the electronic controls and this Bobcat respond
but be very, very clear I'm not saying
that all electronic controls are this way.
There can be some dramatic differences
between manufacturers and the way that their sensitivities are done
or that controls might be built they're going to cause
in the behave that very differently than what this machine does.
I'm not trying to go through and badmouth Bobcat
that's not the point.
What we're trying to show is a reason why you should take the time
to sit in the seat of a machine that you might be considering
and actually operate it because there can be
some very clear differences in the way that they work.
The demonstration that we're going to try to do here today
is the difference between
a hydraulic over hydraulic pilot control like Kubota uses
and electronic or hydraulic control like Bobcat
and many other competitive machines use.
What the difference that you'll notice is
in a mechanically controlled machine you don't have that computer
sitting between the stick and the machine and often times
you'll feel the hydraulic over hydraulic
being a little bit more predictable particularly
when you come to doing fast motion.
The real demonstration that we're going to do here is
what we take this stick and we make quick movements
with the stick typically done to say shake dirt out of a bucket.
If you get your bucket packed full of mud
and you need to get the mud to fall out
you're typically going to jostle your bucket really hard
in order to shake the dirt out.
When you do this with this electronic stick
you'll find that whatever it's doing in its computer
is going to average out and take out that shaking motion
making it more difficult to get a shutter out of the bucket
to knock the dirt loose.
I'm going to start the machine here run into our test pilot dirt
and talk you through some of the things that I'm doing
and sensing the way that the machine is responding.
I'm going to take this guy over here start her up and come around here
in our pile of dirt.
This is just our test pile down here going to the very end of this thing
and try to break this out and get this thing packed good and full.
Now generally what you're going to do in one of these machines
if you're going to be doing your dirty work all day
transporting to another location is going to dump.
If your dirt is really wet and you particularly
if you have a curved back bucket you could find
that you could get that dirt stuck into the back of the bucket.
You're going to come out here lift the machine up
and shake that dirt out and look what I'm doing here.
See how I'm shaking my stick back and forth
and my buckets it's hardly moving.
Now my dirt's not stuck in here you've got to give me that
but there is a rate in here that the stick
is just not responding to my motion.
I'm going to go really quick here and you see
I'm getting basically no movement at all.
Now as I slow down I'll start to gets
a little bit more shake
but just in that much shakeout of it.
You'll notice a whole lot of the motion
that I'm getting here that you're probably seeing
from the bucket might be a little hard to see it
from my perspective but it's actually
a slop in the quick coupler between the coupler and the bucket.
I have a hard time getting quick motions
out of the machine.
When these electronics are always interpreting
what they think I want to be doing and this happens
at high RPM times well here too.
Even with the thing wound out the whole way.
I have a hard time making that aggressive shaking motion.
That's not to say that there's no benefits
to an electronic stick.
One of the things that this machine is able to do
is to switch between different patterns selections.
I have a switch up here my headliner to switch between the ISO controls
or each pattern if you're somebody who likes
the old age pattern control style.
An electronics stick like this is able to do that
and very few operators tend to prefer that anymore
but that is something that this machine will be able to do
that a hydraulic over hydraulic cannot.
I had that same amount of delay in my drive stick as well
if I sit here from a set stand still,
take my RPM's up I go take my left-hand drive stick
and when I go to full right.
See how long it takes between me moving the stick
and the machine responding to my inputs.
This one is not too bad in terms of that area
when I've been on some other machines in the past
you can find that you have to move the stick
a pretty fair distance before it starts to respond.
In the case of the Bobcat, it's actually not that bad.
Again more reason in why you want to actually sit and operate a machine
before you purchased one because that portion of it,
the response at this of the stick and the size of the dead areas
is very different between different manufacturers.
That lag time is awfully odd so here we go, full-throttle
throw it to the side.
It's a solid second and a half before I get heady motion
out of the machine at all and that also happens
when I'm moving.
If I'm going left, and I want to go right
I end up over rotating before the machine responds.
That this one you will notice that some of the newer machines
that are coming out now have adjustments
for how responsive those controls are.
In this case, this one does not have any of those options on it.
You don't have a way in here to say dial-up or down these
and make adjustments to these sticks which is something
that you're starting to see coming out now.
We're going to the same kind of demonstration now on the Kubota.
The Kubota also uses the same pilot control layout
that the Bobcat does but mechanically these sticks are different.
Rather than being electronic sensors in the sticks,
there's actually wet hydraulic lines that go down from them
down to the valve stack.
This would be much the same way that excavator controls are done.
When Kubota design this machine obviously they took all their experience
from the excavator space and use that in the control pattern
on the track loaders.
The one thing that we typically hear from our customers
that are choosing these systems whether an electronic or hydraulic system
is that these are just a little bit more responsive.
You don't have that lag time or computerized
averaging in those things that are happening
in electronics stick and mechanical systems.
The first thing we'll do here is the drive stick.
You remember we were just in the Bobcat
when I move the stick to the side I sit and I wait for it to respond.
When I go into Kubota here, I move almost instantly
and when I come to the side and I go back the other direction
I move much more quickly and I'm not overshooting
as much as I was in the Bobcat.
There's a little bit of a difference in the way these controls work
in terms of how responsive they are.
I'm going to get the same thing in my loader stick here as well.
When I come back and I take my bucket and I want to shake my bucket
you can see how much more violently I'm able to shake.
No matter how fast I shake this stick
that probably shook the living daylights out of the GoPro there.
No matter how fast I do that I get a really hard shake
out of the bucket.
If I'm trying to get that stuck debris out
I could shake much more forcefully than I can with the other machine.
Was talking about dead spots for a little bit too
in the electronic stick and again that's another place
where these hydraulic sticks are just a little bit different.
Once I'd move this handle about half an inch
I can start to hear the valves work.
I get that much more predictable smooth motion
out of this than what I typically would get
in the electronic Bobcat.
Again I'm not trying to make this a competitive comparison
to a Bobcat machines necessarily.
Every generation that comes out they change how these things work
and different machines receive software updates
at different times and really what we're just trying
to demonstrate here is that there's value
when you're taking the time to go out and operate a machine
if you're considering one.
You might hop on one of these and be a [?] pandering guy
and not be able to run a Kubota or you might go and you'll find
that there's an application where you really appreciate
the electronic stick or the adjustability of one.
We are starting to see some applications now
where implements are giving you electronic feedback to the machine
and it can vary its speed based on that implement.
They're niche cases but there's value in coming out
to one of our dealerships and sitting on different machines
and seeing how they work.
Now we're sitting here at a Kubota today
to show the hydraulic over hydraulic capabilities.
We also are a new haul and case dealer as well
who does use an electronic stick and I could say from my experience
it's much more responsive than the one in the Bobcat
that I was just operating.
Again, you know, take the time to hop on a machine to operate it
and really see how you like the feel of it
because there are some significant differences
in the way that these things operate.
That's how some of the mechanical differences
between a hydraulic over hydraulic pilot controlled machine
and electric over hydraulic pilot controlled machine
can seem to an operator.
Again, today not trying to do a competitive comparison
between a Kubota and a Bobcat, that's not really our goal.
More to sit here and say there's good value
in sitting in one of these pieces of equipment
and operating it yourself so you can feel out
some of these differences.
We have the ability to go in our dealership
we're at training events and hop from one machine to the next.
There are definite characteristics that you'll find
between different companies equipment.
If we can show you today one of the tractors
and equipment that we sell.
Come on stop down at one of our lots, we have five locations
in South-central Pennsylvania.
Glad to help you with any parts and service needs
that you might have as well.
