Bobcat with Kubota engine

[ironman1952]

So just purchased a 2026 Bobcat E35R2 and it has a 3 cylinder Kubota engine. I am trying to find some in depth info on the engine.
Does this engine not have a fuel rail sensor?
Is it a turbo?
Is there a source besides the Bobcat service manual?
Something specific to just the engine?
Help !!

There should be an engine model number on the valve cover. Google that for more info.

Your dealer should have, and could still, answer all of these questions for you.

Are you sure its a Kubota engine? My understanding was that Bobcat switched over to Doosan engines around 2014-15.

I just looked it up, and they are running the Kubota D1803-M-DI.

LOL, I just traded for an old Wide Area Mower that a friend did some work to get. He was told it had a rebuilt Perkins diesel in it. I was over there, saw it had been sitting a while and tried to buy it. Finally traded one of my projects for his project. What clinched the deal, was when I opened the hood, I told my friend that the previous owner had lied to him. I said "NO WAY THIS HAS A REBUILT PERKINS DIESEL IN IT! He asked how I knew that, and I pointed out the big letters across the valve cover that said KUBOTA!
A lot of people have equipment that they don't know what engine is in them!

It is a Kubota 3 cyl. I have the full service manual but wanting more specs and a better service manual for that specific engine from Kubota

The older E35 used the D1803, I'm pretty sure the newer models use the Doosan DMo1(D18) which is a 1.8L turbo.
When the switchover occurred I'm not sure, but I know they were switching to Doosan in a lot of their lineup in the 2014-15 timeframe.

Bobcat also list it as a "Bobcat" engine on their website rather than Kubota.
