Picked this up, looks to be fairly complete, know it's a mackissic, but I have no idea what model it is to look for a manual... Even shaft rotation.
It looks to be a mighty Mac, but most of those pictured seem to have a side chute.

Keep that hand out of the chute to avoid nicknames such as "Stumpy" :poke:

The models with the side chute have a flywheel where that driven pulley is and it contains a single knife for wood/limb chipping.

This one appears to have been set up to mount on the front of a tractor with the pulley facing the tractor and pto like a Gravey. 

If you add an engine to the front of this trailer adaption the drive belt and pulleys need to be on the other side for correct rotation. The pulley as it is now needs to turn clock-wise.

Same model with chipper

In a show of force, Alan vows never to miss out on another "too good to be true" deal on a Sears tractor by shredding the competition.  Oh, sorry, I was thinking caption pic.  Nice find Alan.

It would be interesting to find out the reason the why its mounted the way it is. I think it would pile up quickly on the cart. Maybe they channeled into something along side ?

This shredder is based on a model 9P Mackissic shredder.  ....The discharge is toward the rear of the trailer.

 

A MacKissic shredder/chipper with the side chute is based based on a model 12P.

 

Most parts are still available for these models.

Ok, now I know what's in the box (thanks Gary)
Two Q's
What are the parameters for what I can run thru this one (without the side chute)?
And can I move the pulley to the other side?

The discharge is hanging over the end of the cart.

Is the shaft sticking out on the other side? The first file Garry posted above is for a 9P with the pulley on that side.

MacKissic advertised those 9P units as having a 1-1/2" capacity for tree branches.  .....HOWEVER, you can not just toss them in, but have to slowly feed them into the hopper.  ...They will have a tendency to want to pull-in, so BE CAREFUL and keep your hands above the level of the hopper!   .....There is also a tendency for a lot of "blow-back" out of the hopper, so wear eye protection, and keep your face away!   .....Smaller branches and debris can be tossed or shoveled into the hopper.  ....Rocks are not good for the shredder, but clods of dirt will get pulverized.

 

Yours is an earlier model with a low (short) hopper.  ...Later models had a hopper approximately 12" taller, which was much safer.

 

There may not be enough shaft extending out the other side to mount the pulley, but the entire hammermill assy could be switched so that shaft sticks out the opposite side.  .....One of the side frames will need to be removed.  

 

It may be possible to reverse the rotation simply by running the belt with a twist, if there is enough distance.

 

The flails on the hammermill have holes on each end.  ...They can be mounted in 4 positions, so when they are too worn on one edge, they can be re-mounted with a fresh edge in the direction off rotation.  ....To rotate the flails, there are access covers on each sideframe to allow the flail shafts to be removed, without having to remove a side frame.

 

Dry branches will shred easier than fresh-cut branches.  ....Dry leaves will shred easier than wet leaves.

 

The 9P shredders were all made by MacKissic, but appeared in several different colors.  ....The MacKissic brand shredders were green, but some were painted red and had Snapper decals, some were painted yellow and had IH or Hahn decals on them.  ....I think there were some orange shredders sold under the Allis-Chalmers, brand as well.  .....Tractor-mounted units may be various colors.

 

Some free-standing units came with a centrifugal clutch mounted on the engine, while other 9P's had a spring-tensioned clutch using an idler pulley.  ....You will need some method to disengage the shredder from the engine.

I thought I had uploaded a MacKissic brochure previously, but I can't find it in the manuals forum, so maybe I didn't. :wallbanging:

 

I just found this at www.MacKissic.com:

 

http://www.mackissic... hammermill.pdf   Obviously, your shredder does not have the flywheel with chipper blade or side hopper, but everything else should be the same.

I have the wagon style model on 4 wheels with a chipper. I try to chip everything down to about 1/2" and then toss it into the shredder. There is a warning on the safety flap in the shredder that says maximum 1" but anything that big is abusing the machine and your ears.

 

I will say the chipper knife and flails are made of quality material and you know it when you purchase new ones. I have a 24" planer knife grinder so have no problem maintaining a keen edge.

 

I would think the lower hopper was necessary when the unit was tractor mounted.

Bruce, Garry, & all
It's nice to have friends that know what they're talking about. :thumbs:

I won't get to this for a couple of weeks, but now I have a direction.
