Im not connecting. Sharpening an edge on a full-size blade that just has rounded over is far different than running something (perhaps literally) into the ground.

I have at agree with JHZ2. I ran a lawn care business for a number of years and sharpened blades for all my mowers and they never looked like the ones in the picture. Those were abused and should have been replaced.

I'd have never run those blades to that point. Too out of balance, one rock or stick and that could come apart. How many seasons did you run those?

Are you mowing really close in sandy soil?

I don't understand. What does two totally ignored blades have to do with sharpening blades as part of a regular maintenance?

I have two blades for my mower. The one that is on it, and a spare which I sharpen when it comes off the mower, so I can put a sharp blade on whenever I need. The original is 10 years old, and the spare is 9 years old. Neither look anything like the pictures posted by the OP. Both still have factory black paint on them in most areas, and where metal shows, it is shiny. Even after 9-10 years of use and sharpening, they still have plenty of material left. In fact, a visual inspection would reveal only to the most experienced of us that the blades are as old as they are. And they still balance well.

I suspect these two blades came from a mower that has not only always been left outdoors, but parked over something that has constantly been moist.

I got new blades because I couldn't have sharpened these if I wanted to. These came on a 2015 TB Pony. I used them for two seasons and they were actually not cutting that bad considering how they look. It had gotten to where there was a streak of uncut grass in thicker parts of the yard. I was surprised when saw them. They were thin compared to the Copperhead replacement blades I bought. I didn't change anything about the way I mow so these were not the best blades.

The main reason I haven't sharpened my blades in the past was the lack of a grinder, vice, etc. I'll probably start now that I have those items. I think it's odd that the blades deteriorated almost identically. Most of the rusting occured after I removed the blades from the mower. They have been behind my shed for a while and there was about rained almost every day for a few weeks.

How do you still have a deck if that is how blades look after three years? Your not supposed to mow sand.

The deck is in great shape. While I have some thinner spots in the yard, it's mostly covered grass and no sand. I think the blades were the cheapest that could be put on to get the mower shipped to the store. I only paid $999 for the mower. It was the best I could afford at the time. It's been great with the exception of the blades.

Note to self: pick up the mower and have a look the next time I'm shopping for one.

What is a TB Pony? Is it a rider..... a push?... what?


She's the only sister-in-law I have. But she's not my favorite.
