Tractor with gas?

Nice setup Tone. How do you match up the pto speed to the trailer axle? Seems to turn slow.

I was wondering the same thing Don, I guess it must be synced good with the size tires on the wagon with the ’wheel ratio pto’ or what it could be called.
There is also a good flowing hydraulic pump in the excavator, you can do smooth and fast digging with it. Thanks for the movie :blush:

surprising coincidence you beat me to it.
Hi Tone
Is there a speed differential between the tractor’s PTO and the trailer’s drive axle? I’m talking about the speed synchronization of the drive axles.

I’ve already answered this question… :grinning:

It is still hard for me to understand how that can work in all gears. I had an old 4 wheel drive truck once that if the front and rear tires were mismatched they would squawk on a paved road. How does the tractor know what gear ratio the trailer axle is and what size tires it has? Or am I just dumb?

It doesent. You got to match them up yourself when building the trailor by installing the right gear ratio differential, tire size, or by adding a aditional reductor before the diff.

beside 540 RPM, many tractors have PTO mode that is synced with wheels.
people make forest trailers with axles from old three axle trucks.

one reductor box is necessary to match tire sizes though.

I found this INTERESTING FACTS on the internet, I just copied it here

On this day, 99 years ago, Irish engineer Harry Ferguson received a patent for a three-point hitch with a top link, or popularly known here as a “toplinger”. At that time, many other companies tried to solve the problem of accepting tractor attachments in their own ways. After Ferguson’s invention, which was called the Ferguson system, soon all manufacturers of agricultural machinery, including Case and John Deere, adopted Ferguson’s solution as the best.
Here, for all of us who are mowing these days and “unhooking” and “hooking” all day long, let’s remember the Irish engineer and at the end of the day let’s toast with a beer in his honor. Although we prefer wine here in Slovenia, as an Irishman, he certainly preferred beer. It will be expensive for him. Thanks Harry🍺.

That is what threw me off. None of my tractors had anything but straight 540 rpm pto’s.

My Agria turns the axle the other way if I drive backwards :grinning: Maybe I touched something, not ok in my opinion unless you want to drive a trailer like Tone.

Probably most people are on vacation, so there are few posts on this forum,… joke … :smiley:

The classic procedure for starting a tractor on 100% wood gas, … here is this “dance” around the tractor, right JO.:smile:

I installed a vacuum gauge in the intake manifold, it is interesting to monitor the movement of the pointer, full load is -0.1Bar, normal driving -0.2 to -0.4 bar, idle -0.5 to -0.6 bar,
driving downhill -0.8 bar

Yeah, proper waltz steps :smile:

That’s 40 inches of water. It would be interesting to know what’s what - air supply, charbed, filter, throttle. But I know - I still have no idea on my own rigs, except what I’m pulling on the rails.

JO, this measurement tells me how much combustible mixture the engine captures, when it is idling, 40% is enough, it is necessary to take into account that about 10% of the burnt gases remain in the engine (this is the volume of the compression chamber), so, these 40% of the volume are needed for the engine to rotate at all, and the other 50% do the work.
At full power, the vacuum is -0.1 bar, here I lose 10% of the mixture, a lot of this is due to the resistance on the gas mixer (I think 0.05 bar), and the rest is the resistance of the wood gasification system. I think there is no need to reduce the resistance here, it will not bring a big difference in power, especially it does not make sense if the engine has a high CR.

Today that’s funny. Yesterday evening we loaded the last of about 450 “old man bales” into the loft. I feel like it’s vacation time, even if there’s still plenty to do. I have lots of quality help, but some loads I do alone when no one’s available. The electric hoist is a blessing. It’s a lot nicer than filling the front end loader bucket from the trailer, and unloading it in the loft. We also have a beat up bale elevator, but without help, putting a bale on at ground level, climbing the ladder to the loft and picking it up and stacking it, gets old fast. It also tends to blow up some of our less-than-perfect bales.

It’s raining this morning. We’re grateful for God’s kindness in irrigating things for us just when we’ve gotten the hay under cover.

edit:
I forgot to add a Happy Independence Day! We are grateful for the freedom we enjoy, and thankful to God for His goodness and mercy regardless of which direction governments may be going at any particular moment. It is indeed a vacation day, and we will enjoy feasting later, including sweet cherries from the four gallon (15 litre) harvest from the little cherry tree that ripened first.
