Chipper Woodmax three point chipper

[oldafretired]

Was a nice day and found a good size branch that fell from one of the douglas firs so decided to finally test the wood chipper. Still waiting for all the snow to clear from around my big pile of branches you can see in the background.

Seems like it works pretty well.

One thing I have read...and, IIRC, it's in my Woods 5000 manual, is to not run the chipper directly on a hard surface. This, per the manual, results in excessive vibration which can loosen fasterners and crack welds.
No offense or criticism directed toward oldafretired, of course. His pictures (which are very cool!) just show a chipper on concrete

good point Roy. I'm sure he was just testing it. One of the nice features of this style chipper is that you really can go to the source. Which hopefully for the proud owner of his 9900 will never need to be that close to his house.
It is interesting to see the differences between the 8800 and the 9900; bigger unit, different bottom stand, otherwise they look very similar.

Instead of dumping my brush in my burn pit now, it is happily piling up for next time I hook up the chipper.

I'm patiently waiting on mine.... Supposed to ship tomorrow or Wednesday.

Mine is on a trailer somewhere between Chicago and California. Supposed to arrive friday but there's a good chance that when it gets to my local area the shipping company will look up the address and balk at actually driving up here. Woodmaxx had to search to find a shipping company that would do it and I bet this one just said "sure" without checking. I've had a lot of delivery guys call me from the bottom of the road and demand that I meet them there. That's not going to work with a 1000lb chipper. I'll ask them to send their oldest driver. The old guys aren't scared of mountain roads.

I paid the extra $50 to have it delivered with 'tail gate lift service'. We have a 1/2 mile curving stone road which the driver managed well !! Since it came packed in its own steel frame crate it slid off pretty easy to the ground. Good Luck !!

I have the WM8H...like you said...just take it to the pile and start chipping ! We have alot of trails in the forest so i use the chips on the walking trails. Just rotate the discharge chute to where i want to blow them on the trails or blow them into a trailer and take them elsewhere.

Thanks for the good tip.

Yup, it's definitely a big advantage to be able to move the chipper to the area you're working. I have a bunch of saplings all over the place I've been waiting to cut down since my brush pile was getting too big. Now I won't have to worry about brush piles.

The building is just my shop/garage:

Nice setup.

I got my WM-8H yesterday, and spent most of today putting it together. Woodmaxx says 2 hours, it took me 8. I took my time and checked all the bolts including torquing the knife bolts and did almost all of it myself. Getting the panels aligned takes two people. I was working in front of the barn which has no power; power tools would have made it easier. Having all my tools in the barn would have helped too; I walked from the garage/shop to the barn about 40 times.

I ran some brush through it, mostly old stuff. It seemed to work well. I'll give it a more thorough test tomorrow.

I got some time on the chipper this afternoon. It pretty much lives up to my expectations. A fir limb 6" at the butt and 25 feet long went down without noticeable slowing of the engine, on the fastest feed setting. It'll take small stuff too- if you can get it to the rollers it'll go down. However won't eat absolutely everything. A few things jammed in the feed roller, for example a thick limb with a stiff stub on the side. A couple times the vibration caused the feed to shut off. I think the emergency stop bar's weight does it.

The feed on mine seems a bit slower than I thought it'd be. It's probably fine and I'm just used to chuck and duck type chippers. It's fast enough to keep up with me feeding it, unless I'm giving it large diameter long limbs that I can't double up, I'm working from a pile, and I'm moving reasonably fast. I may find a contact tach and measure the roller speed.

boy I sure would feel uncomfortable stuffing a thicker piece into mine at full input speed. That speed is pretty fast on mine cranked all the way out.
Particularly if the piece is hardwood and over four inches perhaps. I would happily trade off performance for less/no damage...

Need to make sure the adjusting nut does not come loose. If it did, the push bar, speed controller, emergency reverse might become useless and that might just be the
time you really, really need to go backwards, like when you shirttail is stuck on the branch...
Good safety check item before starting out.
once upon a time I was an insurance underwriter, trained to think of these things...
None of us want to get sucked into one of these things for sure.
Mine is actually really easy to operate and I felt very safe using it.

But you do have to cut your debris a little differently than before, a different haircut.

 

[RoyJackson]

...like when you shirttail is stuck on the branch...

You really need to dress properly when operating a chipper....that means no gauntlet glove and snug fitting clothing...in my case, at least, no suspenders.
Plus the helmet, face shield and hearing protection, of course.

 

[ericm979]

I'm not sure my full speed feed is the rated full speed. I can move the speed control lever from 10 to 5 and the roller appears to be rotating the same speed. As I move the lever to 4 the roller slows suddenly to a crawl then stops moving entirely. I ordered a cheap contact tachometer to measure before I complain to Woodmaxx. The speed control lever is really stiff and does not need the stop screw to stay in place.

I chipped some more large fir yesterday and did have to slow the feed down as it was slowing the chipper too much with my Branson's 32 pto hp. It's still acceptable; I won't be doing lots of that. I got a piece wedged in the feed opening- a stub on a 6" limb jammed in the travel slot for the feed roller. Had to jam the roller all the way open and use a sawzall on the stub from the side to get it out.

:thumbsup:

Eric, I had to fuss with mine to get it to operate smoothly, so it should not be stiff. I had a certain bolt too tight; at both sides of the bar it's just touching, not tight.

The feed speed control lever I'm talking about is this one:

It doesn't look like there's something I can loosen to affect how hard it is to move the lever (besides the obvious knob) but maybe I'm wrong...

 

[vsteel]

The knob on the lever is the locking knob so you are correct that is the only one. My control is also not linear though the range, it is simply a hydraulic diverter valve. Do make sure when you first run it to run it full speed for a while so it gets all of the air bubbles out of the system. They have the procedure in your directions (just in case you didn't do it).

Mine is stiff as well but I think it is because it has not been used a ton. After the initial remove the bubbles at full speed I set it most of the time and forget it. I don't do a lot of speed adjustments when I am chipping unless I have something large and I really need to slow it down. Most of the time it just stays at the set speed and I don't touch it.

 

[ericm979]

I did do the run in procedure. On mine the roller turned almost immediately. I've got 4.8 hours on it. I hope all the bubbles are out now.
I'll eventually make an extension for the feed speed lever to make it easier to reach in the maze of hoses, and easier to operate. I like controls that work smoothly.

I got a gizmo for touching up the blades from Bailey's. Found out after that it's cheaper here: Amazon.com: AccuSharp 1 Knife Sharpener: Home Improvement

For those with one, how often are you using it? Do you unbolt the knives or are you doing it with the knives in place?

Finally got to start working on my huge pile of branches for about an hour today. There's still snow on part of the pile and a lot of the branches were still stuck together with snow but was able to get about 1/4 of the pile chipped. The Woodmaxx chipper worked great. No jams and it took in even gnarly bent lodgepole branches without a hitch. I thought I would have to trim them but the chipper handled them no problem.

 

[ericm979]

I measured the feed roller RPM- at max speed it's 45, which corresponds to the advertised 75 fpm.
But it's 45 rpm for all settings of the speed control from "10" to below "4". Around "3" there is very narrow range that's 17 rpm, about 28 fpm.
And below that it's 0 rpm. It's difficult to hit the 17 rpm speed.

I sent mail to amanda @ woodmaxx and it was returned saying she no longer works there. I can't find a support email address. Guess I'll have to call them Monday.
