Same fit and function as the manufacturer's replacement part but with huge savings. Lots of rock where I must mow my acreage, but the blades have held up very well. Just sharpened them for the new mowing season and I am ready to go! Definitely a great buy.

I replaced the original blades and these cut the grass! Not sure if they are better or worse than the OEM but they were literally half the price!

Bought my second set after mowing through a forest floor last year with a John Deere zero turn. I know I hit roots, mud clumps, pine cones, small trees, small rocks, fallen limbs etc. I ordered a second set of blades believing the first had to be bent and worn away. When I took them off they were dulled but in tact without bending or chips and still relatively sharp. I'll put on the new set and sharpen the old ones and trade them when the new ones get dull. Very impressed.

Got these and installed on my x350 with no issues at all. Solid blades and like others mentioned they seemed dull but I sharpened them before I installed. To be fair, every blade I have ever purchased comes the same way.

I have a John Deere X350 with the 42 inch high lift deck. I got tired of replacing the OEM blades each year and ordered these blades last year. I used them the whole season last year and I am very satisfied with these blades. The cutting edges easily sharpened for starting the new cutting season this year. The mowing deck does have a problem with the blades hitting (on the trailing edges) and there was some wear from that issue, but it was minor compared to the OEM blades. I am ordering another set of blades to have as spares and I am tossing (recycle can) the OEM blades that I had kept just in case of emergency. These blades cost the same as OEM and are significantly better.

This review is for Pro Parts Place 2 USA Made XHT Blades. I purchased these as replacements on my John Deere Z345R. At first I tried to locate authentic John Deere blades, but they are practically impossible to find. I'm told it is a supply chain issue. These blades were easy to install and they fit perfectly. They're American made, which I really like. They also appear to be more durable than the OEM blades. Overall, I'm very pleased.
