Cutter Blades-To Sharpen Or...

Recommended Posts

andy gartner
...Not to Sharpen, That Is The Question... Around the farm, we don't have many spots of nice grass. Mostly, lots of field grass, punctuated by potholes, tree roots, dips, doodles, fallen tree branches, (not always picked up) and the occasional stone popping up. We always cut as high as possible. While a balanced blade is important, people seem to have differing opinions about sharping blades. Any thoughts on this? :) Thanks for your time, A

The sharper the knife, the better the cut. I do not sharpen without balancing. Bought one of those cheap little cone balancers and now I don't know how I put up with those vibrations for all those years, that I don't have now.

If you look at a blade of grass cut with a sharp mower blade, the end of the grass blade will look like it was cut by scissors, nice and straight and will stay green. If you look at a blade of grass cut with a dull mower blade, the grass blade will look like it was wacked by a machete, ragged and will turn brown in color. This is not healthy for the grass plant. Also, for a healthy lawn, mow high, 2-1/2 to 3" or higher spring thru summer. Taller lawns weather the summer drought better and shade the soil to prevent weeds from starting to grow. Start lowering the mower in the fall (September) to end up at 2" before winter. The short lawn during winter will prevent snow mold and moles.

Thanks, Will get blades sharpened, and balanced, as deck is apart to replace a bad spindle. Had to get a small puller and grind off ends slightly to pull cast iron pulleys. Earlier pulleys? had an allen screw in the pulley V, driven into the key, didn't see this and broke a beautiful pulley. Later ones, no allen screw. A

Got my information from an old Allis Chalmers dealer, "If you keep your blades sharp you will have a lot less problems with belts, less pull on the mower and will cut the grass rather than tear it". I saw him almost get in a fight with a customer one time when the guy was complaining about his tractor not cutting good and that sharpening blades was just a way for the dealer to sell more blades! He also was big on having the deck set up right, with the front a little higher than the back, he said that it cut the clippings up finer. He's gone now but I used to spend a lot of time talking to him, he knew his AC's.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
