Kubota D1105 replacement?

[MultiMow]

I have a turf tractor that's currently powered by an aging Mitsubishi K3D rated at 25hp. I've been told the Kubota D1105 (28hp) is a direct swap, as it was offered in the same chassis.

My hydro trans and PTO boxes are rated for 50hp. The axle is rated for 80hp.

I was just wondering if any other 3cyl diesels offer more horsepower with the same mounts. If I'm going to bother with the swap, I might as well go for all the power I can bolt in without modifications.

Mitsubishi is a much better engine.

Care to elaborate?

Wish he would have answered. I wonder if it is better, why did TORO go to the Kubota engine in the 328D.

I'm not sure... but you, along with everyone I've spoken with, say the Kubota 1105 (28hp 3cyl) was a vast improvement.

By the way, Xfax... I've since sourced a killer deal on some air cooled 2cyl diesels. They're parallel twins, rated @ 20.5hp.

I know it would be a louder and weaker (although, I doubt my K3D retains more than 18hp) engine... but my thoughts are this:

#1- it would be lighter

#2- I could replace the OEM radiator with a high capacity dedicated hydraulic cooler and electric fan

#3- the higher operating RPM might let the hydraulics perform a bit more responsive, AND carry a higher blade speed and travel speed.

What do you think?

The price of the new engine is $600... about $500 less than a complete used Kubota 1105 with with all the ancillaries.

Sounds interesting.

How about some pictures?

Will get a couple tomorrow.

Sorry it took so long, Xfax... but my source lost the bid on those engines. He's always coming across deals. I'll keep you posted.

No problem, I don't need one.

Was just curious.
