Rated 5.0 out of 5.0 by Nice little tiller When I was researching small gas tillers, I soon realized that the Ryobi engine (power head) had the same displacement as many other tillers in my budget range - about 26cc - and I already had the engine and some other attachments. So I picked up this unit, and haven't regretted it. It's a little heavy, but the included adjustable shoulder strap helps distribute the weight. It doesn't cut through sod - but I understand that most residential tillers don't either. It has jammed a couple of times when fist-sized rocks got wedged between the tines, but usually these can be removed fairly easily, although once I had to get a hammer. It does a great job of mixing compost from our compost bins into the garden soil. We use it for our flower gardens and several small vegetable plots, including some box gardens. May 26, 2013
Rated 4.0 out of 5.0 by great for small jobs It's great for small beds where the soil has already been agitated but not so great for larger jobs. The weight is a little light so it requires quite a bit of downward force, and is somewhat unwieldy. October 14, 2011
Rated 5.0 out of 5.0 by Roto tiller I bought this last night. I tilled my garden of about 30' x 8' in about 30 minutes with NO back ache. The only thing I can say about this tiller is " I LOVE IT, I LOVE IT, I LOVE IT" May 27, 2011
Rated 3.0 out of 5.0 by Minimal Efficiency This product attaches easily to universal brand fit attachments for line trimmers (Ryobi, Craftsmen etc). It is cheaper than a regular tiller-cultivator, but takes a lot more time and effort to till deep enough. Functions okay for small areas. I used it to till a small vegetable garden bed (10' x 15'), but I had to use a pick and shovel in conjunction with the cultivator tool to get the job done adequately. Overall it was faster and easier than digging it up with just hand tools. It would be cheaper and more efficient to rent a regular tiller-cultivator for larger areas. I will be using this for my small vegetable garden every year though. June 16, 2015
Rated 5.0 out of 5.0 by Very happy with this product I purchased the trimmer over a month ago and I've been very happy with my decision. I love the fact that it's rechargable and doesn't require a fuel mixture. I've always had trouble with gas powered trimmers in the past. Always difficult to start and I didn't know whether the gas/oil mixture was wrong, the mixture was too old, was I pulling the cord enough times or quickly enough........ Now? I squeeze the handles and it starts. I can shut it off and restart with no problem. Awesome! It's easy to assemble. I also purchased a cultivator attatchment for the trimmer. The trimmer and the cultivator attatchment are easily assembled and disassembled. The cultivator attatchment works very well, also happy with that. It's pretty powerful and stops itself immediately if it gets tangled in something. It IS a bit heavy. And, although the handles are adjustable, the ergonomics are not ideal for me but I'll live with it. I find that the battery lasts for about an hour. Takes an hour and a half to two hours to recharge. I'm thinking about getting another battery to allow me to run it almost continuously. It was money well spent, in my opinion. August 4, 2015
Rated 5.0 out of 5.0 by Tool does the job We have a3 acres of lawns, flowerbeds, garden, etc. and needed a tool for cultivating. We use a 27cc Husqvarna 2 cycle trimmer which accepts attachments. Worried initially that the powerhead may be underpowered and few of the reviews we read stated the size of the power head being used. Could not find any recommendations as to minimum power for this piece online either. With Home Depot's return policy read, we pulled the trigger and purchased the unit. The cultivator works as stated in the descriptions. There is no question it is a heavy piece yet that is an advantage when running it. The 27cc power head handled it more than adequately. The garden had been tilled 2 mos previous to using the cultivator and it went right through everything in the predominantly clay soil without a problem. If you want to simply remove surface weeds/growth moving forward works fine. If you want to till to any depth and really get a good finely ground soil you will be better off moving backwards with the unit allowing the weight to hold it in the ground and grind away.The recommended time arrangements are useful and they do work as described. This unit chewed through 1" soft pine tree roots without straining the power head. We also tackled a larger flowerbed 32'L x 6'W which has never been tilled and it was work but the tool handled it. Not really made for initial tilling although if you can stay with it; it is work have no doubt, it will do the job. You will know you worked when you are done with it and the results are impressive. Recommended for any cultivating job you might have. It will jam up if a rock is caught just right in the times between the shield...what till doesn't? Pry it out and keep working. Do not keep trying to use the throttle when a jam occurs as you are burning your power head's clutch if you do. Cleaning is easy. Any tiller will get grass/weeds/roots wound around the tine shaft sooner or later and have to be cleaned. Pull the pin on the shaft end and slide off the tines and the grass/weeds slide right off the end of the shaft. We feel this was a great purchase and the gardens have never looked better. We will also be using it to amend the soil in the beds and garden at years end adding compost in the fall. Small unit does work around the plants well and with a little use after an hour or so you can be very good with it getting great results. Recommended. May 23, 2015
Rated 1.0 out of 5.0 by Good idea, but poor product. First, the tiller is way too heavy, which resulted in the bending of the shaft of the ryobi motor. I used it to mostly mix my compost (leaves, grass clippings). Small root tend to get stuck on the tiller, which force me to do frequents stop to remove them. After just two sessions, the tiller stops working. I made the corresponding claim to the store where I bought it (Home Depot), who not only did not replaced it, but wanted to charged me a $20 diagnostic fee in order to send it to a facility that will take care of the warranty. After speaking with the supervisor and then the manager, the fee was finally waived. It is been almost three month, and no tiller yet. They inform me they are still working on it. This is insane! What kind of warranty is it? July 27, 2015
Rated 5.0 out of 5.0 by Used to till my hard, rocky front yard for new planting I have nothing but good things to say about this cultivator. I used with my Husqvarna 128LD with no problems at all. The thing is heavy, so if you're not a strong person, you should maybe take frequent breaks if you use it as I did. The soil that I used this on was hard and rocky, but the thing kept going with no problems, other than getting roots swirled up in it. The blades still look new in spite of all I put it through, and I used it for a good 16 hours overall. I wouldn't suggest using it to till up your 3600+ square foot yard, but if you don't know anyone with a tiller, then this should be your cheaper go-to. It'll take longer, but hey! It's only time, right? And one can always buy more time, no? What? Dang! Shoulda bought a tiller then...oh well. April 30, 2014
