PowerTrim Pro Series Sprinkler System Heads Grass Cutter, Lawn Trimmer, 7" Diameter Round Cutting Blade, Garden Yard Tools, PTC-007

Works excellent. It doesn't come with mounting hardware so you will have to buy a blade mounting hardware kit for your specific trimmer. I have a Stihl so I got the blade mounting pieces for $25 and it works great. Makes a nice professional looking cut that you cant get with a string trimmer. Wish it came with basic hardware like a washer and nut but overall its all good. It does what I need it to do and considering buying another for a backup.

Works but a little unstable when lowering downward. Tends to catch the edges of the opening around the sprinkler donut hole so a clear perfect circular cut is difficult to obtain. Gas powered trimmer best - battery powered not quite enough to get it started again after trimmer head getting caught on hole edge and stopping

Works great, did not come with hardware so had to figure that out

When I received this item, the box came in a wrapped package no damage. I opened the box. The product was inside the box with one little metal ring, no explanation on how to install and no information regarding where to find information to install. Nothing highly disappointed in the lack of instructions.

The description says it comes with a 1” spacer for longer arbors, but it was not included. Haven’t tried it yet, but as other reviewer stated you need your own hardware to mount. Since the arbor is much smaller than the hole, you need to have a washer to be able to hold it on.
