Deere site reviews indicate the X754 has overheating issues. Why not X750 or X758?

Humm, interesting, no numbers, just green and red.

I finally remembered to do this.
Here is where my X750 temp gauge sits, doesn't move for anything,
not once in five years has it gotten any higher than this, mowing hours on end in 90+ weather.

Is this what the rest of you are seeing?

Yep, that is the same place on the gauge as ours runs too.

On the 2019 dash for the 700 Signature Series, this is what they look like.
3 notches showing is the hottest it has ever been, I know, not many hours.

new dash, have to admit not all that easy to read, kind of like the old style better for viewing, but I'm sure this
shows more data points, alarming, idiot lights. Oh to have six nice round gauges in front of us...

please note the little hole above your steering wheel. After five years enough dirt and crud fell in that hole and that steering wheel tilt mechanism
to totally lock mine up. Had to get dealer to take it apart, clean it, worked fine.

I bought a spare mower belt just to have, not cheap, but oem at 600+ hours still going fine.
Going to wait to see how long it lasts or until it starts to come apart.
I am going to replace the rollers on the deck this weekend, left side ones have flattened a little.
They were 8 bucks apiece or something reasonable, in a nice green box too.

It is the fine dry debris that most quickly clogs the radiator and extra cooler. I've applied extra sealing around any minor openings, but in the end it is simple clogging. The temp gauge climbs and then the PTO cuts off (thermo switch I am told) and then if not immediately cooled down, the engine will shut down. This is again is our 754. And yes, we think it is terrific other than shutting down regularly while mowing dry grasses.

Really frustrated.

Don't know the history of your X754, and wonder if water has been used to try to clean the radiator fins. If so, I'd suspect there is mud caked in there and restricting air flow.

 

[Haasman]

beentere- I was thinking that a good project for today. I have some mowing to do so I'll do that first. Good suggestion. I'll report back whether it makes any difference.

Sorry to report that with dry, light grass(es) swirling around the tractor still ends up on the radiator. First PTO thermal cut-off comes on (no mower) and then at even high temps the motor will stop.

I have no idea what to do at this point. Has done this since the first day. I have had John Deere dealer reps out multiple times. Had the John Deere District Service Rep come out and he replaced the engine fan. Still the same.

We really like this tractor and mower. One of Deere's best, except for the overheating problem.

can only guess you have a coolant blockage somewhere or clogged radiator. All of which JD techs should have picked up on.
Possibly a bad waterpump? Bad radiator cap?

Mine continues to operate flawlessly at 730 hours; wish yours did

I think you have a legitimate reason to ask JD Corporate to give you a replacement mower
