I started with one of these...
..........and thought it might be easier to use if it had an electric motor.

First project, sharpen the blade..

...dont bother with the sound as the router motor on the grinder is a real screamer!

Purists will see that the grindstone is rotating in the wrong direction, too bad, the router motor does not like to be reversed.

Reel mowers rarely need sharpening and can usually be touched up with abrasive paste and spinning the reel backwards known as the back lapping method. There are kits for doing this but the easiest way is to take off one wheel and flip the dog over so that that wheel will drive when going backwards, then apply paste to the blades, flip the mower over and push it around the yard until you get tired, do that a couple of times and the job is done. But on this old mower the blades were a bit past that so I ground them, they will likely need the back lapping process to finish the job.

I have one of those ... I consider it yard art, and it's going to stay that way!

I had a lot of fun playing with one of those old reel mowers that has a 5 hp engine. It cuts grass great as long as I cut the grass twice a week. If the grass grows more than 2" the mover blade pushes the grass over instead of cutting it off. The blade works like a combine the blade has to pull the grass in to cut it but if the grass is above center of the blade it gets pushed forward and it does not cut. I had fun fixing the old mower up like brand new again but after I discovered I had to mow the lawn twice a week I sold it on ebay for $850. and some guy drove 280 miles to my house to pick it up.

That's why you have to pull it back and then push forward. Even if their gas powered they're still way too much work. Glad you found a good home for yours.
(why arn't robotics being applied where they're really needed?)

I have a battery powered reel mower and it is a pleasure to use. It just floats along with no effort and does a very nice job of clipping. The battery last a long time too, more than enough for the house lawns. We also have a battery powered rotary mower and it is just as nice plus it will cut the deeper grass and weeds. While batteries haven't improved all that much the motors sure have. The use of super magnets makes the batteries last 2 or 3 times as long for the same power output.

Sounds as though you have no idea what happens when a wheel is overspeeded. You are lucky that you are not killed or maimed.

I promise not to push the mower that fast.:confused:

The only nice thing about push mowers is that they can only take a toe or two.

A manual push mower does have its advantages...

I converted a Suffolk Colt mower
Though not a freshly repainted one!

I used a 750 Watt (S1 rating - continuous) 24v motor that had been rewound with wire of twice the cross sectional area (same number of turns, the slots were half empty). Running on 12 volt it moved at a pretty brisk walking pace and was pretty much unstoppable if it could find traction.

I would like a mower of that style Paul, I think that would be a nice conversion.

We have only a smallish lawn and I ensured there were plenty of power sockets around outside the house so I will be using mains for my electric mower. The motor I have on the bench is only 1/6 horsepower so I am fully prepared to accept that it might not be able to spin the reel in which case I might have to buy a motor, the next few days will tell.

Of course I should have cleaned and painted this old mower but I got a bit sidetracked and started taking it apart after nothing more that an bit of a scratch at the thick dirt with a stick. If it works well it will certainly be getting a classy paint job.:)

This is the lawn mower I want. The neighbor will be calling code on me again for sure expecially if I put straight pipes on the exhaust.

A reel mower sure does make a nice looking lawn. You don't get it any better.
