6" vs 8" chipper for 30hp

[eco88]

Just ordered a 6" chipper by woodland mills, the TF68 PRO. Has a dual flywheel and is rated for 20-50hp.
It would be going on a kioti DK4210SE, that has about 30hp at the pto.

Ever since, I've been thinking about whether I should have gone with the 8" one, the TF810 PRO, but it says it prefers 35-100hp.

I wouldn't be pushing anything over 5" through in either, I'm just thinking about the bigger opening on the 8", which is 8x10, vs the 6" that has 6x8 opening.

Also the flywheel is probably much heavier on the 8", makes chewing easier, but probably takes a lot out of the pto to spin it.

Just got hit with a massive ice storm, have probably several months if not all year to clean up this mess.
It's about 90% pine, and about 10% cherry and maple.

Anyone saying go with bigger?
Keep thinking about upgrading before they ship it out. Not sure.

I'd be guided by WM's recommendation. It'd be disappointing if you ordered the 8" model only to find the performance was lack-lustre.

^^^^
What he said.
Also, I have always found that they like a steady diet of half the rated size.

I have the WM 6 inch chipper. 200 hours or so on it. Use it mostly on my old Ford 641 with 48 hp rated WHEN NEW. Being a 1959 model probably less now. Occasionally use it on my Kubota 50 hp.
Anyway I suggest sticking to the 6 inch. Even a 5 inch solid stick to chip is asking a lot of mine. Although the bigger throat makes it easier to push through crooked branches and stuff.
Go with what the WM guys say. They are pretty good.

I can stop my 60HP tractor with an 8" chipper

In general I don't chip 8" logs due to the engine braking but I do find the larger capacity better for chipping branches.

Sounds good thank you. Sticking with the 6" then

Good choice.
An 18 volt top-handle chainsaw pares up good with a chipper.

That's exactly what I have. Sometimes a branch with a tight bend is enough to prevent the infeed roller grabbing it, so even though it might be quite small, it can stop in it's tracks this beast of a machine which can easily devour large logs!

Most of the time, the saw just sits there in the holder, but when you need it, it's right there.

The holder is great and convenient. I think I ordered it as an option. Recommend it.

I just looked into that. This one apparently comes with a holder.
