IMG_0894.JPG IMG_0895.JPG IMG_0950.JPG IMG_0951.JPG Hi folks,

With the price of gas going through the roof and the fact I cut about 3 acres of lawn I have wanted to convert a large frame to a diesel for some time. A few years ago I picked up a HT 20 that after blowing the kohler the last owner tore the whole tractor apart. Since then I have been looking for a cheap 2 cylinder liquid cooled motor, last weekend I got lucky at an auction and found what I wanted for a price I was quite happy to pay.

I have started fitting it together and while the height and width are a good fit I will have to stretch the tractor...

Gas is just over $2.20 a gal here but diesel is over $3.  Don't follow your reasoning.  If buying new a diesel will last a lot longer then gas but you pay a bunch more for it also.  Should be a fun project just the same.  Have a diesel in a Cub with 50" deck and I love it.  If I could just get a pivot wheel under the center - - -.

Sorry if the gas vs diesel is not making sense to some, here in Eastern Ontario they are often about the same price per liter, today gas is 1.10 and diesel is 1.13 (about 4.10 a us gallon).. the economy is the diesel engine consumes half compared to the big Kohler twin.

To be honest it is probably more likely as chief fan said; it should be a fun project

Good luck with your project. I've done several conversions and have no regrets.

You might want to take a page out of Bolen's book when they made the HDT1000.

 

Instead of stretching the frame to accommodate the longer 3-cyl Mitsubishi, they added a plate to support the fuel tank and battery.

Then you'll have to stretch the hood to match!

Thanks for all the words of encouragement! The engine is a Petter marine diesel, don't know much about them but the engine is rated to run at 3600 rpm which I thought was pretty high for a diesel, I am anxious to here it run.

I think to make it fit I will both stretch the frame 5 inches, this line the front engine pulley with the PTO, and overhang the front by 4 inches as tractorholic suggests... don't wont to ruin the turning any more than I have to. That of course will mean a 9 inch longer hood. I have the hulk of a 1250 that will be donating frame and hood I think.

Looks like a great start to a very robust project;)

Im curious, any way you could take some shots looking down between the engine, and dash. Maybe some side shots back there too?

I'd just like too see more of your project; )

Either way, you would have to stretch the hood.
