This will be the official repower thread for my custom Commado 8 "Autism Horse".  Pictured below is the tractor as she is today with her Kohler K181, and a couple pictures from the eba

I just purchased this WH with plans to take the Lister-Petters out of a Hydro WH to put in here. I had it in a manual WH before and it made a much better combination. The hydro takes too much horse power to operate. And yes the Hood will have to be raised to accommodate it. The gentleman is suppose to hold it a couple months till I can get up there to get it.

This is the tractor during construction that it is in now.

Great looking rig!!!

I'm kinda confused on the hydro taking too much power post?? It would be a challenge to over work that Diesel!

Hydros do sap power compared to a gear drive tractor.  The story on the cub cadet line and the first hydrostatic drive garden tractor they did discusses this issue.   Also, at plow days, you have to "baby sit" a hydro with constant adjustments to maintain ground speed.  With a gear drive, pick your best gear and sit back and let the plow eat dirt!  My whole plan is to make the install look factory as possible with little to no hood modifications.   The Yanmar is 7hp with the torque of nearly a 10hp gas engine.  It will just fit under the hood with the hood fully closed as I had the seller give me a height measurement before I purchased the engine.    Mike

My Lister is only 5 hp. at the rpm's the governor is set for. It totally destroyed the transmission on the first WH. I'm hoping the 16 hp. WH has a heftier gearbox. We could put the tractor against a power pole in second gear high range and it would dig those over sized ATV tires down to the frame on hard ground. The next one will not be abused as it is such a pleasure to use in the garden. The sound of that low rpm diesel is pure music.

Here it is installed in the first WH with the stick transmission. I will try and make a Video of it today so you can hear it starting and running.

Might only be 5 hp, but the torque pulse is what killed the transmission.  Same issues with the transmissions in the early Dodge Ram's with the Cummins diesel, they didnt put up with the torque from the I6 for very long.  Beefing them up was the only solution, espically in a truck that was "turned" up.     The little Yanmars are very smooth, have internal counter balance shafts to smooth them out.    Mike

Here is the sound. I found this old video and after this I'm out of here as I've hijacked your thread for too long already.

When do you think you will have your engine in hand? Your going enjoy this project. Get your belt length and alignment right and the rest is a walk in the park. Hope you will post photos as you go.

Should have engine and shaft adapter before the end of the week.  I should be able to keep the same belts as the crank height is the same between the two engines.  If not, the local Rural King is 5 min from my house.  BTDT!  Might start on it Sunday or later next week, Have a tractor show to take her to this weekend.  So one more show as a gasser!    Mike

I would think most of wheelhorse trans are same??  Seems there is more idle gears in the differentials or such is the difference?  Putting these big Deisels in a tractor doesn't win any "looks" contest for sure. Maybe that Yanmar will be little nicer looking, looks neat just as it is in the pictures. Has one beefy starter on it for a little guy. Does one need to get bigger battery's to make these turn over?  There was a fella at the Wheelhorse gathering s that always had those in some racy looking chassis and he would go out on the road and race off!  He could even do Wheelies AND, get this.....shifted the manual trans, stock he said, into next gear w/out using clutch!  Was neat as heck. He had about three of them in diff sizes.

 

Found some pix from that show.  Seems I'm missing a couple, didn't see in my pictures that were one he raced up road. That little rig had tiny engine, not a diesel, but was kinda rat-rod cute.

What you want is the trans with 1 1/8" axles, 8 pinions and maybe posi if your pulling.

 

​Edit: This trans is capable of withstanding 35-40hp in pulling matches.

 

I'm curious to know if your autism horse has any savant abilities.

Not true with my Hogzilla.  I leave my hydro set at full speed, then use my throttle to set my ground speed.  But then it's 25hp diesel, and the heavy duty hydro/trans out of a Simplicity, same as what's in a John Deere 430.  I've had lots of smaller hydro's, but wasn't into the plowing with them back then.  I'm sure the smaller ones did have the issues you speak of.

Oh, and Mike, that little Yanmar looks to be perfect for the WH.  What is it's HP rating?

The Yanmar is 6.6hp at 3600 rpm.  And the Autism Horse has no more of any savant abilities than I do.  Common misconception that all autistics have some kind of savant ability.  I am gifted in the mechanical ablities area as long as it it not to complex.  I need to get a new tach a matic for the mower deck, mine is very worn and it lets the mower deck get cockeyed and then it binds against the bottom of the tractor's frame.   Yes, some of the diesel installs leave less to be desired in the cosmetics department.  I am trying to keep it factory looking as possible.  Mike

Thanks for the explanation. I didn't mean to imply that you did, but hey, It's a Wheel Horse. They're all high functioning!
