Tomorrow I'm going to pick up a Murray "chain drive" 5hp tiller that has a sleeve hitch. I've never seen one of these - only have one picture of it, it looks something like a Sears. Supposed to run but need a spring on the carburetor. It's powered by a Briggs and is supposed to be 36" wide.

Click for a big view:



Does anybody have a manual or any info on this?

(getting the tractor, too!)
 
I wonder if it was made by Agri-Fab for Murray. Maybe check the manuals on their website. There's several manuals for pull behind tillers. I've never looked through them all, but you might take a look.

Good call - it looks pretty close to the Agri-Fab, other than the hitch.

I'll be able to find out more when I get a model number, I guess.
 
I don't know anything about them and I have only seen 1 other. Defenetly post more pics and info. I will post a link in the Murray forum so more of the "Murray Nuts" will se it. I will also post a link to a thread that has some info on Murray tillers

Yep, those sure look like the same thing. Neat!

Thanks for looking. I searched some but must have missed both of those threads.

My guess would be that it's an older model Agri-Fab, and possibly that Agri-Fab made some modifications to its standard design to suit Murray's wishes. Again, though, that's just a guess. It's neat, though.

You don't want to know.

It was a package deal with the tractor.

Seller said it was missing a spring from the carburetor. I'm not sure where, because it runs and governs just fine. The choke rod is missing a nut, I think, and the choke mechanism may be where the spring was because I had to hold the choke open while it was running. Honestly, I think I'll just put a spring on to hold the choke open and just manually actuate the choke when I need it. It originally was linked to the throttle so when it was beyond the fast position it actuated the choke.

As typical for Briggs, the one-way clutch on the recoil needs a spot of oil because it shrieks at random times. Easy fix.

Engine runs, tines turn - if I had a tractor set up with a sleeve hitch I could be turning ground over in a half an hour, I'm sure. The previous previous owner had fabbed up a place to hook the tiller to the back of the tractor but it was nothing like a proper sleeve hitch and didn't allow for any lifting or lowering.

I got some pictures, will add them later. Working on the tractor, now. The solenoid for the starter isn't engaging.

Tractor runs, too...

Pictures! Click for a big version.



A little hard to read, but this is the model number stamped into the blower housing. Looks like it is an '86?













The threaded rod sticking straight up is supposed to have a nut on the top, I think. The linkage it is through goes to the choke.



The tines are kind of odd... only two per position and they are welded on to the shaft as an assembly.

Other than running it with the tines in the air, I haven't actually used it. I don't have a tractor with a sleeve hitch right now. I'll have to build an adapter for the 3-point on my MTD 990.

I haven't been able to find an owner's manual for it yet, but an Agri-Fab manual is probably close enough. I'll have to look for one of those to see what the chaincase is supposed to have for lube. It's a little wet where the shafts for the tines come out. Being chain drive, it's probably not fussy. I'm thinking chainsaw bar and chain oil might not be a bad idea. It would stick to the chains.

I've never seen an air filter like that on a Briggs Pulsa-jet carburetor. I haven't had the top off yet, but it looks like it is probably a pleated paper cylinder where they usually use a flatter oiled foam element. A modification for tiller duty to cope with the heavy dust, perhaps?
 
For a manual maybe try matching it up to it's Craftsman counterpart, I would imagine that there is one.
 
If the chain is internal and in a oil bath you wont want to go to heavy on the oil if it's a fast moving chain. I don't think it will be a 90wt oil like a car diff..

I can't really tell from the drawing... It looks like it's an open chain in a sealed chain guard but I can't be sure.
 
Here's a little better image:

87-13450.pdf

It looks like the chain case (Transmission) will take sae30 non-detergent oil.

Looks like the engine will take the typical sae30 also when operating above 32°F.

Till at 2MPH or at full throttle on the tiller and low gear on the tractor and med throttle. Adjustments may be necessary for ground conditions and preferred depth.

Max depth seams to be 6".

The more I look at it the more I like it. :)
