6" vs 8" chipper for 30hp

You will be glad you stayed with a 6" chipper at that PTO. I usually figure a 6" chipper should get a diet of almost all 4" and under material, occasionally larger. Just to keep everything running smoothly.

Ditto with an 8" chipper and maybe 6" material.

So did a lot of clean-up the last 7 days. Put the chipper through hell. 7 days of about 10hrs a day. 70% red and white pine, 30% maple and cherry.

Couple of weeks ago did a similar thing. So probably close to 140ish hours under its belt.

The 6" is good for the tractor I have. Maple and cherry 4" make it work extra hard. It struggles, but keeps going.
6" green pine, especially the white pine, it eats like nothing. You can definitely tell a difference when switching to red pine. It's much tougher.
Haven't choked the tractor yet. I keep it at a steady 2000 rpms as most of my pto implements.
On the last day the shear pin snapped.
I found some cheap chinesium nuts and bolts in my garage and used them as temporary measure. Snapped 3 more within few hours. Glad I didn't use those bolts on something more important.
Either way, shopping for shear pins now.

Blades are double sided. Had to flip them around after few days of maple and cherry and old hard pine. It chipped the edges a bit. With the green pine no issues at all. The other side is still razor sharp.

The only thing I wasn't a fan of, is the damn throat. Eventhough it's a 6x8, you don't realize how little that opening is until you start feeding it tree tops. Especially the pine, red even worse, with the crazy web of branches. Even the inch or 2 offshoots will make it get stuck and render the infeed roller useless. Then it's either keep pushing by force and hope it gets in, or yank out and clip off. Pia.

Either way. Great machine. Well worth the money. Wish I had a bigger tractor so I could have gotten the 8" one.

Too bad you don't have a wood stove for winter heat... or an outdoor fire pit on the deck for evening "ambiance".

I try not to chip anything over about three inch . burn the rest for heat.

Spent 6 hours feeding the chipper three days ago. Plum wore myself out.

That Makita electric chainsaw is an effort saver.
