John Deere L120 over heating?

[sheetmetalbabe]

The design is to cool with outdoor ambient air rather than the flywheel air pump attempting to cool with hot air from the engine compartment. It needs the hood and the plenum.

Could it be a carb issue?

Can be as mentioned earlier running on the lean side. BUT, if yours drinks gas like mine that won't be the problem.

Tinner talk LOLOL!!!! You are right but I actually looked it up in the JD Parts Catalog so you all would know what I was talking about
I am also a commercial/industrial roofer, but that talk isn't allowed on here, aahahaha.
Yes, my John Deere looks like that, just no bumper and some peeling pain and a little rust on the deck. I bought it in 2005!
I always mow at full throttle, in case you were wondering.
I call the JD dealer so much they offered me a job :laughing: So is mowing without the hood on a really bad idea?
I don't mean to be such a girl but I thought it would stay cool that way. It has cooled off at least 10 degrees in the last hour, maybe 15. I am going to go see how many laps I can get.
I will be back......

I bought my JD LX277 at auction. It had no hood.
I use it without one. The 4 parts needed to replace would be $500-600 dollars

A hood is decoration and protection from the rain. I do not mow in the rain.
A push mower does not have a hood.

Well.....
Called the JD dealer and talked to a different guy, he said it is NOT the coil! He had no clue without seeing it. It's $45.00 just for them to come and get it
He mentioned a compression test but I am clueless on that one and sure I don't have the tool to do it. I might try a fuel pump??
I have a Dodge 1500 4x4. It was doing the same thing, would be going down the highway and it would lose all power. We didn't think it was the fuel pump because I replaced it once.
If I waited 5 minutes on the side of the road, it would be OK and I would make it home. Any thoughts??

Thanks again for everyone trying to help. It's hard when you can't see the actual mower.
I appreciate it!! :biggrin:

So you saying we don't need to operate the way they were designed to operate.

If it's that way the next time you need to change oil but all you have handy is automatic transmission fluid just put that in and it'll be ok.

So the guy on the phone is guessing the same as we are.

Even though I have no doubt you know what's hot and what's not, let's back up and do some temperature investigation of just how hot it is.

REALLY? The John Deere Tech, who is certified in John Deer repair, said "OIL IS OIL IT SHOULDN'T MATTER". And that was my thought.
That is a far cry from transmission fluid. If all you have are sarcastic comments, keep them to yourself.
Can your wife put new drag links, steering sector and a pinion gear on your mower?? Maybe rebuild the deck while she is at it? I think not. :confused2:

Yes, you are right about the guy on the phone. We are all guessing. I do appreciate all of your time though.
I now agree with you on the overheating thing also. I tried this morning and got one lap in and it died. And it wasn't hot because it didn't run for more than 3 minutes.
My pickup truck was doing the same thing and it ended up being the fuel pump. I went and bought one, just got back. I noticed the fuel filter was full and it usually only gets halfway full.
I am thinking the pump can't keep up. It looks like an easy fix to me. I know about the infra red temp gun because we use them on torch down roofs to check for
hot spots before we leave so we don't set a building on fire. I don't have one and don't know where the guys that do have one are working. BUT you were right! It's not overheating.
Chock one up for Motoman!!! I will let you know if it works.........

I would run it till it shuts off then check for spark. As soon as it shuts off.

How do I check for spark?
I did replace the fuel pump. Super easy. I mowed a half acre, but it still isn't quite right. It is better but it surges, if I turn the PTO off it will get back to running OK.
If I turn PTO back on it dies but starts right back up. Before it would just die and not start for half hour or so.
Maybe there were 2 problems?? I did put a voltage regulator on in the fall and that made a HUGH difference. :smile:
