- Hi, guys!
Welcome back to my small engine repair channel.
In today's video,
I'll be showing you why you may get a no start
or no crank issue on your yard machines,
ride-on mower, like this one.
Now, this is a common issue on this machine here.
That's why I want to show this to you guys, today.
So here's a closeup look at this machine here.
Engine's at the back.
It's only got one blade.
It's got a small deck.
And it's made by MTD, Yard Machines.
Again, as I mentioned in the intro here,
I often get these machines.
They come in the shop, the customer will say,
"I go to start it up," or "I was riding the machine.
All of a sudden it died.
I went to start it and there is absolutely
nothing going on.
And when I say there's nothing going on,
there's absolutely nothing going on.
It's not even clicking.
Not even a hissing noise or anything like that."
The customer was using this machine.
And he said it just basically abruptly died on him
and has not started since.
Now, before I get to the most common issue on this tractor,
I'm just going to show you what you should check, also.
You'd wanna make sure you have a good battery.
And you also wanna make sure that the fuse over here,
which is on this connector,
you wanna make sure it's good.
So it's really easy.
You just pull the fuse out and look at the tab inside.
Now, for those of you who aren't familiar with fuses
and what to look for,
you wanna make sure that the little metal tab inside
or the connector between the two tabs is not burnt.
So as expected, this fuse is still good.
And on this tractor here,
you wanna reach out underneath here,
and make sure that the plug on the switch here,
is connected properly.
So these are just additional things here to check.
Now, let's get right into the main problem
that's causing this.
What it is, is a safety switch on the lawn tractor.
And specifically, it's the safety switch
that is right back here,
right behind this plastic cover here.
So again, here's the safety switch right here.
Now, because of the plastic design of the chute,
sometimes the plastic moves up and sometimes
the plastic even warps.
There's a lot of vibration on this tractor.
It's a single cylinder engine.
And basically, it's this flap here,
that's keeping the switch pushed in.
So after a while, what happens is the plastic moves
and the switch pops back out.
So what I'll do here is take the cover off.
There's two knobs.
There's one here and one on the other side.
I'll just show you how it works
so you get an understanding of it.
Then I'll show you a quick fix.
So I'll get these two knobs out first.
Pull the whole cover off.
So here's the safety switch I'm talking about.
When the plastic's on properly,
it keeps it pushed in permanently,
so that the machine can run.
And like I mentioned earlier,
sometimes the plastic moves and it allows the switch
to just pop out like this and stay like that.
Once your switch is out like that,
the machine will not run.
It will not start or do anything.
So this is a really quick fix, guys.
I'm going to put the cover back on.
Again, when you put the cover on,
make sure this is pushed in.
You want this area of the cover to go here.
So I'll just tighten up the knobs here.
So this is a really easy fix, guys,
that will cure this problem permanently.
I'm just going to grab my drill with a 3/16ths drill bit.
And what I'm going to do is drill a hole right here.
It's gonna go through the plastic and the metal deck.

And now what you need is a quarter by 20, self-tapping bolt.
And now what I'm going to do is basically,
screw in this bolt with my impact.
It's going to hold this part of the cover down on the deck,
so that the switch can not be deactivated.
(drill engine roaring)
Now, if you want, you can go put a nut
on the other side of the bolt, if you want.
And there's basically, three to four inches between the tip
of this bolt that I just put in and the blade.
So you don't need to worry about that.
So here you can see just by putting that bolt,
it's keeping the part flush with the deck.
And it's always going to keep that switch depressed,
so you won't have those problems anymore.
So when you buy these machines brand new,
the plastic is not warped.
That's why you don't really get any issues at the beginning.
But after a few years, sometimes it warps
and it deactivates or the switch comes out
and then you can't start your machine anymore.
So it's that simple, guys,
all you need is a drill 3/16ths drill bit
and a quarter 20, self-tapping bolt.
Just do that and you will never have this problem again.
This machine will turn over and start up right away.
