As a side note, wheel weights are not easy to find for these tractors.

I run a YM2002D and 54 tiller, I have never felt the need for added ballast while tilling.

My substantially smaller YM186D runs the 54" Yanmar tiller (RS1400) with no ballast needed - although without the loader it might need 100 lbs on the front, to plant the front tires firmly in order to make sharp turns with the tiller lifted. Horsepower (18) is just barely adequate, occasionally a full-depth first pass can stall it.

I've read that Deere weights fit on Yanmars but they are real expensive. For rear weights on the YM186D I finally adapted two 70 lb weights off Unknown (I suspect Case front wheels), grinding out a cavity on each for the tire valve then bolting them on. I later bought four wheel weights off a 1980's 20 hp Kubota but I've never mounted them. They would need drilling new bolt holes right through them. The more practical use is hang them from the qhitch on the back, to counterbalance carrying gravel etc in the loader.

Along your repurpose idea. I picked up some old weights from a weight bench. My plan was to weld a piece of rebar onto the boxblade vertically or two, one on each corner and put those round weights on it with the bar running through the center to give more down pressure on the box.

You can get creative on how to add more weight in areas you want it.

Are you saying the tach is labelled for the various rpms needed to attain PTO 540 in the various pto gears?

Here's the YM2000/YM240 tach diagram. For US YM240 with two speed PTO, 2200 @ engine gives 540 or 1000 rpm at the PTO.

For your first question, the answer is YES.

And we had discussed this last year here: See page #2 and my post #15.

Now that makes a whole bunch of sense now. One the YM US models, there is only PTO on or PTO off. For my YM2610, this seems to equal the PTO selector #1. Nice find. :thumbsup:

A borrowed picture here may be worth more than words. I believe this was from a 2610 but could be wrong on the model

As I understood the explanation with this picture, regardless of what PTO range is selected, he could match his engine rpm’s to generate 540 PTO rom’s. [
This pucture is from my YM2002D and I do not have that extra info on it.

Mine has 3 PTO ranges I have looked it up in the past but forget exact numbers and am not where the manuals are so here are approximate speeds at operating engine rpm’s of around 2500 rpm

1=540
2=760
3=1000

Hope this helps clarify.

Yes, that is my borrowed pix from my tractor. lol Sorry it was wet after the wash and blurry. Here's a better one I took last week as the hour meter just rolled over.



Bummer there isn't a second inside PTO selector arc curve in your RPM tach gauge. You could pick PTO #2 and run the tractor to 2200rpm and probably hit 540rpm on the PTO output. Likewise applying the same principle to PTO #3 and maybe run the tractor at 1200rpm to probably arrive at 540rpm on the PTO output.

So, if you have an automotive timing light or an adjustable strobe light, you can tune what RPMs gets the other PTO selectors for 540 PTO speed rpms on the output. There Are a few good YT vids showing how to track and set a strobe at a constant speed, then keeping that setting on the strobe, change to the other PTO selections and adjust the engine RPMs till the strobe matches either in stillness or a pulse that you can count in a rhythm.

Your Yanmar has some hidden talent ready to be utilized. :thumbsup:

Sounds like your Yanmar is fully capable to do this, just that the indicator on the tach isn't there.

This thread is amazing. It's sort of let's talk about anything with our Yanmars. It's covered a bunch of ground already.

I've got the equipment I could actually make some if it came down to it. Ain't nothing you can't do with a bridgeport and a lathe

Same weight is available on Amazon as well. I was looking at them recently to add ballast to my skid steer and increase the tip load a bit....

That would be one way to go. It is possible you could build them in a way to keep the individual weight down yo make them manageable. One of the issues with wheel weight (at least on bigger tractors that I messed with) is managing the weight in a confined space. Thank God you stack them for increased weight, but even then managing the alignment with the holes inside the wheel could be a pain. Perhaps half a circle and interlocking somehow. Just food for consideration as you design if you design.
