Not too many brands around anymore.
Look at the Wallenstien, Woodland Mills WC46, Titan has 2 models, WoodMax WM-8H, ...
Northern Tool use to have a good model for SCUT tractors. They no longer carry it. It's the only small PTO chipper I've seen in action that works rather well.

They now carry another brand, MerryMac. Less powerful for a higher price.

Not sure where you are located to provide any more help.

I don't have a YM-155D, so feel free to ignore this.
I have the WoodMax WM-8H, and have 30HP at the PTO, and I find the Woodmax underpowered. It is good with green material, but dry, four to six inch diameter material often jams it when the last 8" are going into the chipping blades. I have seen it used with 80HP at the PTO and it never stalled. One small point is that the WM-8H has a hydraulic feed that takes some HP.
I think that you might be ok with a leaf shredder, but I think that the lack of HP would be a frustration with a wood chipper on a YM-155D.
All the best,
Peter

I can tell you what doesn't work! 
I bought HF's shredder with the 5.5hp gas engine when I had a major landscape pruning project, and more than a trailerload of material to convert to mulch. I found it would only take soft green material up to about 3/4", a size you could break over your knee or cut with loppers. Larger material had to be fed very very slowly. Maybe several seconds per inch. The thing was more a frustration maker than a useful tool. I spent most of an afternoon mulching the heavily loaded trailer in the photo below.
I also learned it was suitable only for the long straight green material I bought it for. This is an orchard, with lots of pruning debris that is larger and generally has a crooked shape that won't go in the mouth. So its useless for orchard work.
Finally this particular HF design had a low-oil shutoff that made it impossible to keep running. That was so sensitive that as engine vibration made it settle slightly into the ground it would shut down. It needed a sheet of plywood beneath it, carefully shimmed to perfectly level, to run at all.
Hopefully HF's more recent model works better!

There are some recommendations for PTO chippers in that thread.

I'm new here so I'm gonna christen this topic with another 3 point chipper that is actually rated at a minimum 15 HP at the pto. Either way the hp is on the lite side for a power hungry attachment.

How does it perform with 2" and less green stuff.

The YM 155D at 1146 # is a bit light to carry the WM WC46 chipper unless you only run it on level ground. It's very noticeable back there on the 1600ish # 2025R.
A lighter chipper/shredder would be the MacKissic TPH-123. I had a TPH-122 for 16 years. It's one of the lighter weigh ones. A guy bought it and is using it now on his 3 series JD.
That "Merry Mac" that others posted a picture of looks like the Mac TPH-122.

Knowing there are single stage and two stage PTO driven snow blowers out there, is there such a thing for these woodchippers. It would explain why some of these machines can much on larger diameter branches at lower Hp.
So are there 2-stage PTO woodchippers then?

I don't believe so (on the 2stage). Of course the ratio of the pulleys mean a lot.
The bigger the chipper the bigger and heavier the flywheel. Rotating mass I believe is the secret. Plus bigger and more knives.
That's where all the hp is needed.
All my own opinion...

I sold my 8Hp machine that had 2 cutters when I got it. Opened it up and the 3rd one was missing. Order another cutter and it indeed was a huge difference. So huge the machine was scary at first. Dropped in a 3 inch branch and it disappear in under a second. Totally vanished. The Techumseh engine was impressive.
