PTO chipper WoodMaxx new MX-9900

[disney]

Wondering if the problem is they are simply too green?

This is the first year with the small chipper... typically rent a small commercial mid January for a final clean up.

The thought was to use the PTO chipper as needed during the season when things are slow.

The feed peels more than grabs if this makes sense.

Like you said maybe they are too green, Try leaving them 'dry out' for a few days. If it takes say 5 days to dry, just make a pile for each day, and then the crew can shred the 1st pile on the 6th day. I know with my bearcat, chipping palm fronds, it does help to feed some real wood every so often. (not that you have any palm fronds around...)

Sounds like it's just too much to go down the chute.
Try removing some of the large lower branches and feeding them separately from the tree.

Will do... I think my brother might have expected too much?

I will need to investigate, maybe the knives need to be adjusted???

What size PTO HP are you running it on? I use mine on my 2555 and run spruce tops along with some really thick green pine branches and I haven't has any problems clogging. If it starts to bog down I slow the feed to keep the RMPs up and it chews it right up.

He has a Kubota L3800... the unit does not bog so I have been told... he runs it right at PTO speed... I was wondering it he could go a little higher?

I had to google the specs, but it looks like the l3800 only has about 30hp at the pto, I know the larger flywheel of the wood max will help it through a tough section, but I wonder if the power is an issue. I dont know it the 110 is close by, but with only a few more ponies, I don't know if that would make a difference. Have you tried asking woodmaxx, I thought I had heard they have good customer service.

Looking at the Woodmaxx 9900 spec and the minimum recommended PTO HP says: (25 Minimum PTO horsepower), Your running close to the bottom end so it might have something to do with your clogging. The only time I have eve had an issue with clogging or RPM's dropping is on a 7 or 8 inch half punky poplar with feed rate set to max. all I do is stop the feed let the RPM's build back up and continue at a slower feed rate.

I've used my MX9900 for 2 years now and I've chipped over 100 tons. Other than a bad hydraulic pump pulley in the very beginning (Woodmaxx replaced overnight) I've had no problems with the machine.

IIRC, that chipper has hydraulic feed. I haven't been following this thread to closely, but I'm thinking the feed rate might have to be slowed a bit.

As suggested the clearance of the knives was many times wider than spec...

I was not there but that is what my brother found... he used the thickness of a credit card to adjust in the field and performance improved greatly... clogging just about disappeared.

Still not 100% on the feed... seems even smaller Christmas Trees are enough to overcome the feed... he was hoping the small stuff could be fed butt end first and would self feed while getting the next one... about 60 trees to chip from this season... about 1650 sold.

Looking at your addresses, i assume in Olympia area you are trying to chip cultured firs,dugs and nobles, maybe. The limbs are small in diameter but very strong and it takes a bigger machine to chow down on that stuff, at least from my experience, running my own pro chipper and also many years of aborist grade pull behind the truck machines.
