Anyone with the new 425...

If you have a new PT-425, it would be great if you could post a few pictures of the engine compartment and pump arrangement. The picture below really caught my attention. In addition to the Kohler engine, it looks like they may have gone to a metal gas tank, added a water separator, and put the engine in "backwards." This would put the variable displacement pump on the front of the engine under the fuel tank. The engine would pull cooling air in from behind the seat? This could be a much better set up to deal with the heat issues.

Also, any pictures of the variable displacement pump (likely under the fuel tank) would be greatly appreciated as I hear they've recently gone to a different pump.

Interesting. That's about the same layout as my 2001 model year. What year is that photo and where did it come from?

- My PTO and Steering pumps are behind the engine like that.
- My tram pump is in front of the engine under my fuel tank like that.
- You can see the red positive battery terminal under the muffler, so the batterie is in the same place as mine, which means you'd have to remove the muffler to change the battery like mine.
- It has a factory Kohler muffler like mine, which exits straight out the rear. I've NEVER had heat issues with my machine.'
- It appears the hydraulic filter is in the same place as mine.
- My fuel tank is plastic, but in the same position as that metal one.
- That appears to be a vacuum fuel pump VS the mechanical one that was in my right valve cover.
- Mine didn't come with a water separator.

I think I like my layout best because of the factory exhaust. I think PT's home brew exhaust may have caused a lot of heat issues from what I've read here over the past 18 years, and I don't care for the ones that exit out the side.

It's a current picture from PT's website....

OK I see it. I'd definitely question the age of that photo. They aren't known for keeping them up-to-date. So, we'll wait for someone with a new PT425 to chime in.

Yeah, you may be right. I've never seen that specific 425 configuration before though. Hopefully, someone will chime in with a new one....

The image is dated April 21, 2017. It could have been taken before that date.

Hopefully Incline will see this thread because he has a 2018, 425 with a Kohler.

Ahhh... I went back and found his posts. He posted pictures of his new baby in this thread...

Well, if that is the new arrangement, it may eliminate the vapour-lock issue. The battery separates the engine from the gas tank, and it looks like there's a metal heat shield designed to protect the battery. The gas in the tank should stay cool, but I'll bet the battery gets pretty hot and the outside may tend to melt. There will be some heat to the battery in the winter, and that's good. I also like that the terminals are easy to access.

That's one odd-looking muffler, and located outside the engine compartment I'd be worried about it igniting stray bits of dry grass thrown up by the rear wheel.
