I wish I had boulders like that! I sure wouldn't bury them. This is coming from someone that has as much rock as dirt but none bigger than cantaloupes.
I keep my mower blades sharp and I don't square the ends up. The tips wear off fairly quickly to a round profile and if I squared them up each time, pretty soon the blade would be too short to overlap the cut. I don't find a rounded end to be any less of a cut than a square end as long as it is sharp. I have lots of rocks, sticks and crawfish and ant beds to mow over so I have to sharpen about every 3rd mowing (about 18 acres total) to keep the tips(first 3") sharp.ok, let me understand this better please...you mean the very end of the blade you want to remain at 90 degrees and not smoothed over from sharpening?
Like a tooth on a chain saw...
Funny, I always pay extra attention to the end to make sure it's super sharp, figuring it's the first thing that hits.
maybe I should be spending more time trueing the end.
I know the blades are sharp when they make a sound like slicing crisp lettuce.
I also sharpen the reverse side of the edge lightly, like a knife.
All of this is a terrible idea if you mind sharpening blades. I don't...frankly find it very satisfying.
I find I am able to run my mowers and tractors at lower rpm and still maintain a nice cut with sharper blades.
My landscaper who helps me mow just runs his JD zturn flat out, letting tip speed beat it off. He has been mowing lawns for twenty years and has
never sharpened a blade. Many folks don't; replacement blades today aren't that expensive if you don't buy oem.
So neither way is right, I just grew up on the farm sharpening mower blades on a stand up grinder and I guess I've never stopped.
I would have went in the same direction of the hills on the first pass. The back lid on the tiller would have helped drag down the hump. If needing a second pass, a diagonal cut would have been the way to go. Alternately two diagonal pass in an X shape would have worked I think but maybe not as well as following the rows the first time.3L, looks good, can't imagine doing that in an open tractor. Must have been a bumpy ride that first pass.
When I did the same thing harrowing my neighbor farmer's field, helping him out when his tractor broke, he suggested I go "with the grain" the first pass and the opposite direction
or 45 degrees off the next. I hit a couple of "waves" out there that I thought would break something on the front axle but the tractor is much tougher than I am.
Is there a better way doing this? For those of you who do this for a living...
