Back-Lapping Crank

Back lapping crank is a mechanical process of sharpening and cleaning the cutting blades of a reel lawn mower. This is done by rotating the crank backwards which drives the reel backwards while abrasive compound is applied to the blades. The process removes any dull or nicked edges and creates a smooth, sharp surface for a more precise and cleaner cut.

It works, like my mower is brand new. Some complaints for reviews saying it did nothing, follow a few steps and it should work for you. 1 read the direction that come with the sharpening compound. Really that’s all you have to do, and it’ll work, but if you’re too lazy to read the manual just watch a YouTube video on it. MAKE SURE you adjust the mower blades, as directed, and if needed, which I had to do, apply more compound to the blades as I found some more needed to be added while I was rotating the blades.

    I believe that this kit will work really well for those with newer movers that have not seen too much use.

    I decided to give it a try on my old mower, that is at least 50 years old and has never been sharpened. The blades were a wreck. And of course I had no illusion about hand cranking it to get a good result. So I didn't. I attached the appropriate sized six point socket to a powerful corded drill and away I went. It took a good half hour of reapplying grit and readjusting the mower blade cutting bar. In the end, though, it produced a good result--not factory perfect, but so that it cuts now far better than before.

    In general it sharpened the blades but the silver crank tool didn’t totally fit on my mower, so I had to really ram it on there and just make sure it would stay together while cranking it for ten minutes. Other than that as advertised. The brush isn’t that good, but it’s disposable so as expected.

    I use to use a drill and socket to turn the cutter but going too fast tends to fling the compound around too much. The hand crank to easy to use and much simpler.

    The kit provides good value for what it is. I didn't love the price when I saw it but when it arrived and I got a sense for how much of the sharpening compound comes with it, I feel now that the value is not too bad. And when I run out of the compound I'll still have the crank and brush to use, and can always purchase more compound from a local shop.

    My reel mower needed to be sharpened. I had noticed the grass was cutting unevenly. There would be stretches where it was not cut and figured I needed the blades sharpened.

    The kit comes with a set of instructions, a brush, handle to crank the reel, and a small tub of sharpening compound. People have complained about the poor quality of the brush. It is a non-issue for me. Brush is of a lower quality but keep in mind what you are applying (sharpening compound).

    The instructions were well laid out and the process was straight forward. After sharpening the blades, I took it for a quick test and my mover was back to like new again. Smooth cuts!

    Definitely recommend this if you find your reel mower is not cutting as well as it used to.

    The lapping compound was great, but the crank didn't fit my Husqvarna mower. We reversed the wheels, using a technique found on You Tube, so that the cylinder ran backwards with the lapping compound on the blades. A bit fiddly, but worked like a charm!

    My earth wise mower needed sharpening. I tried buying everything to do this like valve lapping compound and a giant deep well socket and of course I forgot to get an adapter so I could chuck it to the drill. Even without the adapter and with a cheap socket set I'm in for 2 to 3 times the price of the kit. So I just ordered the kit and it seems to work relatively well. I guess the most annoying part is the cleanup and bed knife adjustment. Neither of those things are going to be better with the other system.

    5.0 out of 5 stars Expertly Sharpens Blades...A Couple Of Tips
    Reviewed in the United States on May 30, 2010
    Verified Purchase
    I bought an old time hand push mower about 3 years ago. Though I have definitely found it to be inferior to a power mower in its ability to pass over many a tall blade of grass or weed, its superiority in its ease of use and dependability has sold me on them for life. I would never use a power mower again. (Not with my size lawn anyway).

    The rotary blades on the hand mower do not sharpen, nor do they cut the same way as the single blade design of a power mower. While power mowers can be easily sharpened at an angle with just a file if necessary, the rotary blades of the hand mower are sharpened flat across the face of the blade. Something very difficult to do by hand even if you had the mower completely disassembled. This very simple three piece system consists of a brush, a crank handle, and a small container of grinding compound. The instructions that come with the kit are pretty simple without a lot of detail, but describe it well enough for you to get the job done. Personally, I found the hardest part of the whole job at the very beginning. Removing the small "C" clamp that holds the wheel on. Though the instructions simply stated that one should pry off the C ring by merely "sticking a regular slotted screw driver into the opening" of it, for me there was nothing at all "merely" about it. No amount of prying, twisting, pushing or swearing allowed me to get a grip on the C clamp with just a screwdriver, or even two of them. All I ended up doing for 15 minutes was chase it around the axle. I finally got it off by concluding that I would sacrifice it by ruining it with needle nose pliers, and then putting on a new one. (As it turned out, I easily reshaped the original clamp and reinstalled it). After removing the clamp the wheel slips right off and you have to remove the gear wheel that assures the forward action of the blades when it motion. It is not attached in any way and just lifts off. But one word of warning here. Neither the directions or any other reviewer at the time of this writing mentions that the gear wheel directs its forward motion by the wheel slipping over a little "key" or steel sliver that slides into a slot on the gear shaft. The key is loose after removal of the gear wheel and can easily fall out and be lost while moving the mower around during the sharpening process. Make sure you either keep an eye on it in the shaft, or remove it to a safe place. The actual sharpening process is quite easy, just time consuming. You spread the compound onto the blades with the little brush supplied and then turn the mower back wards with the crank provided. You will get tired, but you can rest and restart. Give it a good ten minutes. The more you crank the better the sharpening job. Oh and the crank does not slip over the entire shaft, it is snug and has to be wiggled on. You may want to tap it with a light hammer or screwdriver so you don't have to keep stopping and pushing it back on during the spinning process. When you're done, the reassembly is very easy, (don't forget the little key if you removed it), and after cleaning up the excess compound, your mower will cut like its a brand new model. It really did make quite a difference for me and I highly recommend this simple kit that will perform the job easily. Push mower blades stay sharp a lot longer than power blades so a sharpening job every other season, or even every three should be enough. Under that schedule, this kit should last you through many years of your mowers use. Highly recommended....
