Rated 5 out of 5 by from There are cheaper units but you get what you pay for. This thing is amazing. It does small and large jobs. The wheels make it very easy to control. The soil comes out great with the tines that came with it. Could not be happier with the performance!

Rated 5 out of 5 by from Great time saving tool I recently purchased this unit with the power sweep attachment. The job that took me 3-4 hours by hand was done in 45 minutes! It was not a cheap purchase but if you are looking at getting spring raking done in less time this is the tool for you.

Rated 5 out of 5 by from Yard boss 55 Good pricing, works the ground very well, however get the bolo tines they do the job better than the ones that come on it. Scott from straubs equipment very nice and knows his products.

Rated 4 out of 5 by from Useful tool Got this to prepare planting beds and use the power sweep attachment as well. Does the job as expected. Sometimes hard to start, as is my Stihl chainsaw. Once running it's fine. Useful machine once I got past the upfront cost to own.

Rated 4 out of 5 by from Small tiller for weeding and defining beds I've owned a MM55C for a few years and it's good for weeding beds, enlarging small beds, cutting curves and getting into tight spaces.Pro:LighweightRemovable tinesEasy to cleanDecent powerStarts easily IF you do the proper post season maintenanceVersatile - can be run with 2,3 or 4 tinesFolds up neatly and fits into most car trunks with easeCon:NEEDS A MUD FLAP! I added one because this unit throws dirt all over your feet at full power without a mud flap.Be SURE to run the fuel tank dry before storage and avoid gas/ethanol mixtures. Even 10% ethanol in gas will cause the carb on this unit to foul. I replaced the carb and it ran like new. Took the old one apart and it was totally green inside even with the use of Stabil ethanol stabilizer.
