Answer: 
The tilling width is 13", the width of the tiller. It is not adjustable. Works kind of like a hand mixer in your garden.

Obviously to protect the engine, it has some sort of an "automatic transmission" design so a jam like this doesn't ruin the motor. So, this is what I'd think that "black goo" is from. A form of hydraulic grease. )
Since you say you've owned it for many years, and these cost just $89 brand new, I'd say it has given you a very good service life, and it's now time to simply replace it. It's old and worn out.

Answer: 
It's just grease. Something like SKU 153429 There is a small nut on the side that could be replaced by a grease fitting, but if it's leaking, I'd take it apart (T25 bolts), scrape the edge and run a bead of gasket maker over it SKU 1001218056 You'll have to take the shield off first (4 bolts) and the tines (hitch pins) to separate the two halves of the gear box, but then it's easy. just a worm drive.

Expand-It Universal Cultivator String Trimmer Attachment is rated 4.2 out of 5 by 231.
Rated 2 out of 5 by from I have a Ryobi Expand-it power unit and have used it for many years with my lawn trimmer and edge... I have a Ryobi Expand-it power unit and have used it for many years with my lawn trimmer and edger, so I thought when I decreased the size of my garden that this unit would be just the ticket. I was wrong, I used it for about an hour before it seized up and I had to take it back to the store. I'm sure it is fine for real light tilling but not so requiring it to work hard on clay soil. The store clerk showed me a unit that much better suited my needs and was less hard on me to move around. This unit is not that light weight when you are trying to use it for any length of time, my forearm began to get tired and sore.

Rated 5 out of 5 by from Perfect for Small Garden I bought this with Ryobi 40V powerhead along with the trimmer and edger attachments. I have a newly built house with VERY clay-heavy soil all over the property. My previous attempt to loosen a small patch of front landscape garden with a rake only ended with back pain and embarrassment among neighbors. Once I got the hang of using this cultivator attachment, loosening the dry clay soil was ridiculously easy. Even with the electric powerhead, the tiller didn't hesitate at all (well, except when I got a large rock bound between the tine and the guard...). I'm working on loosening the rest of the backyard soil so that the grass seeds will take for the spring. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Good for plants and gardens I bought this Ryobi cultivator to attach to my Cub Cadet power head. It has the universal connector that you find on many consumer models ( I have read that echo and sthil have their own connectors.) it is a solid unit. it was hard to get through dry Oregon clay. watering it down the day before helped and breaking it up with a shovel or pick gives you pieces that the tiller can chew up. your arms do get a good work out. This is definitely for gardens and bushes. If you are doing a lawn rent a good rear tine tiller.

Rated 1 out of 5 by from Bad transmission? The very first time I went to use it... It worked a few minutes, then as I sped up this tool into the ground, it locked up and it rattled very loudly bouncing upwards. I'm a mechanic with many years of experience and a tool guy. I didn't open the tool to fix it. I wasn't going to fix a brand new tool. I believe the transmission was either put together wrong or there is a design flaw on the transmission of rotational force. I don't tecomend this brand on this product.

Rated 4 out of 5 by from Cultivator attachment This thing is a workhorse! I bought it a few days ago to till the surface of my yard so I could re-seed it, and I was amazed how well it dug into the hard-cement GA clay that I have in my front yard. It even chewed through small (< 1-inch) roots! It was a bit difficult to maneuver and handle and at times couldn't dig too very deep without making several passes, but I was still very impressed with the quick work it made of the clay. The only drawback I can think of for now and the reason why I knocked off one star is the weight. Combined with the weight of the trimmer, it was a bit too heavy. However, I still think it was worth every penny.

This is a decent product if you are doing simple tilling and not in heavy clay as I was. I am hard on whatever tools I use and in digging a trench for a drain for my gutter it caused so much torque that it busted the top off my weedeater and that one is currently still dead. It was an old one so no real loss there, but it did snap the motor housing into 2 pieces, with no injury to me. But if you need to dig a trench I have started using my gas powered post hole digger to that, as well as dig the holes for my fence posts. I used it to run 100' of electrical line which had to be buried 18" deep. I drill hole after hole and just drill the sides out and empty the dirt out with a shovel, was 10 hr project from start to finish, but I own the post hole digger vs renting a trencher that would have cost $200 for a day. Its still alot of work.

Doubt it would work as effectively on hard soil but in my raised beds, where the soil is not as compacted, it worked great! Works the soil up very well to clear out unwanted growth and to prepare the soil for new plants or seeds. Works great with the Ryobi 4-cycle motor drive unit. Love the 4-cycle! At little more costly but well work it not having to mix oil and gas.

Rated 2 out of 5 by from Ryobi tilling cultivator It works very well in soft soil. But for anything hard or firm the machine is too light. Fix this review site also it is so screwed up I had to re write this review 3 times. It has a problem backing up and deleting letters. Good luck maybe that's what you want so people get frustrated and give up. Not leaving a review
