Descriptions didn’t give compression ratio says high compression flat top pistons no Pin height given tried contacting vendor to ask questions waiting for a callback.

The reason I asked was I have heard some of the guys saying that they were getting compression ratios of 12:1 with flat top pistons and some had to run aviation fuel.

It's not because they are flat top pistons. It's because they are so tall they have 12 to 1 compression ratio. A flat top piston in an AC of a specific pin height is higher compression than a Power crater piston of the same exact height because there is no bowl.

You probably already know the pin height needed don’t you dr to get 8.2 to 1

For 4.125" bore pistons with flat tops, I calculate a piston pin height of 2.300" to 2.305" to come out at 8.2 to 1.

If I were wanting to run a round baler, the best modification I'd do to my D17's engine, is to get a Two-Twenty with a cab and AC. Why? The D17 is a fantastic tractor for raking hay, and making square bales. In my Grandfather's words, it was the 'finest hay-making tractor ever built'... and I agree, for the probably millions of square bales we put up... and that was the mainstay production system, until the Hesston square-baler showed up. Grandpa ran some round bales with the D17, but it wasn't the tractor's engine that was the greatest need, it was environmental comfort and safety. Running the big roundie was absolutely impossible if the breeze came at you from any direction other than directly in your face. I would not recommend an engine build investment on a D17 simply to run a round baler... I'd get a higher-power tractor with cab and AC... because there's a whole lot more to being effective and comfortable making round bales, than just compression ratio and fuel octane and PTO horsepower. IF you have to build an engine's output up to make enough power for an agricultural load application, there's more significant problems waiting in the field that will stop your production when you're in the most operational peril.

Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest.

Yeah, I understand it’s not big enough for today’s standards, but I only got one horse to feed not going in the business of making hay Mostly fun and don’t want to deal with a little square bales

The more economically sensible option, then, is to buy round bales... and either pay a little to have them delivered, or borrow a bale mover. I'm neither an equestrian enthusiast nor a cattleman, but I've been just-entwined-enough in both to get the picture... For just one horse, you'd get much better quality, and lower waste with hand fed squares. The other option, if you REALLY want to bale, and particularly if you're looking for an outlet for historical enthusiasm, is to look for an Allis Roto-Baler. It'll run nicely behind a WD-and-up. They made a cool loader to pick 'em up, too. Putting cubic money into an engine may bring up PTO horsepower, it doesn't address any other issues that a large round baler's operation includes.

Buying them is not as fun probably have to break down and get a bigger one after I’m done dealing with this one

dont know a bout a round baler but i grew up with a freind that baled round bales with a 3020 john deere but the d17 running the new holland small square baler is the best hay baling combo ever made, we custom baled in all conditions with a d17d when i was young

That's exactly what my Grandfather used... I spent three long weeks each summer on the rack with my uncle, loading them from stern to stem, hitching 10 racks up in a train, to the 6x6, with four more in the field, he sent me to drive that train through the field, up the apron, across the road, and up the gravel hill, into the big field north of the dairy barn, then into a big circle, set the brakes, shut it down, leave it in low, and walk the two miles back down to help fill the last four. My hands hurt just thinkin' about throwin' all those bales. The 6x6 went mebbie a whole 4mph in 4th gear throttled to 1200rpm, and while it was a really uncomfortable noisy drive, it sure felt nice to spend 20 minutes off my feet while that beast growled up that grade.

Even with a cab tractor while round baling I would turn out of the windrow to face the wind. Takes more time, yep, could not stand all that dust and debris getting in every nook and cranny.
