56V reel mower

  • Under Consideration
Somehow I doubt that there is going to be a whole lot of demand for this, but there are some times where grass requires slicing instead of chopping, particularly in instances involving centipede grass. I have st. augustine and bermuda, so it isn't a problem for me in particular, but I imagine that there are some people that will find an electric reel mower particularly appealing considering the better quality cutting of the grass.

I agree!  I would be a buyer!

I'm no engineer, but wouldn't that require a LOT of power, and finicky adjustments?  I once had a Scotts reel mower and it was impossible to get it to both push easily, AND cut properly.  The blades had to kiss each other just "so" in order to cut, without putting undo strain on the operator.  I ended up getting sick of messing with and bought a power mower.  So glad I did.

There are industrial mowers that can be fit with multiple reels. I believe the forward momentum and cutting power are completely independent, so it can be done. For less than 4 figures and using battery power though... might be quite an engineering feat!

A 21" reel mower can easily be driven by the trimmer motor. There are a few 24v ones on the market. My 5' 3 gang mower is completely ground driven.

Nope. Reel mowers take significantly less power to run than a rotary mower. You could never make a rotary mower that is ground driven. And yes, they are a pain to maintain.

I currently have a fiskars reel mower, and it requires very little maintenance as the blades barely touch. I think a powered version of this would do quite well. I live near Houston Texas and have St. Augustine grass.

Im building one right now. Ill post pictures when im done. The fiskars 18" is amazingly setup to be easily powered. Im going to run 5 of them because i spend waaaay too much time mowing.

Jacob, I demand a full write up of the procedure!!! 5 of them? How is that going to work? You and all the neighborhood kids ganged up like snow plows on a multi-lane highway???

Nope. All connected together, then a self propell driving unit. Eventually i want them to be robotic and mow for me. Easy to do with reel mowers

Well..... easy-ish. Just need super accurate gps so i can have beautiful lines

Yeah I was thinking you could center a power source on some angle iron between the handles then disconnect the chain from the wheels to the barrel and connect a belt with pulley to the reel (not sure a chain would work as it might spin to fast for the chain)

I plan on putting a motor with belt to step down the rpm to the shaft the wheels are on, and driving it that way. Ill take the paws out of the wheels.

I'm in the process of taking my fiskar reel mower and converting it over to electric and self propelled and using an ego mower for the parts.

With enough people documenting these builds, maybe this can become a common thing like swapping a v8 into a Miata! :-)

I am going to attempt to use the 12" trimmer motor first. Then if i have to, ill use the mower parts. I just dont have a controller. Im thinking about using a 60v hub motor for a bike because it has low rpm

Low RPM would be a huge plus. I was looking into using a 15" Ego trimmer as donor parts for an e-bike, but such high gear reduction becomes a challenge in a DIY application.

E-bike hub motors are a fairly mature tech at this point, and from what I understand some of the more common lower power units are fairly cheap as well.

I have found some for under 200. Brushless. 300 watt is what i may use. Or 500 watt. The hardest part is finding something compatable with 56v. So 60v should be ok.... or 48v. Advice please. 48v is much easier to find

I'm no expert, but I'd say look at the voltage "range" of the motor. The Ego packs peak at just about 58v, and average about 50.4v (3.6v/cell). A 48v motor might work if its operating range is wide enough. Personally, I'd be more worried about the controller voltage range than the motor.

Just use the reverse of a voltage multiplier or a step-down transformer or something.

Hey.. so... my propel motor is getting hot for my sweetness

https://youtu.be/XGkd7TBO2a4

Whats goin on with it. Its a motor from a donor 20"mower using a pwm controller (china made).

I need to gear it down more i know... but smells like burning motor. Plus amp draw is crazy high for the propel motor. Perhaps im throttling it too much.

I mowed most of my lawn today. Less than an hour.. this thing makes short work of a large lot.

So...no ideas huh. I ordered a 60v brushless motor today, planetary gearbox in the head. Hopefully it works and fixes the issue.

Where did you get the 60V motor?  I've been trying for a long time to find an 80V one, but have failed to find one.

What kind of cooling system do you have near the motor and what is the motor's RPM, torque, and how many amps are going through it?

I didnt put an ammeter on it yet. Cooling system hasnt been developed yet. Got the motor on ebay. Got all of them on ebay.

The current motor is from a 20" mower. It does like to run at low rpms, heats up pretty fast. It has plenty of power, i just think that the 0 ramp up inrush of amps is causing way too much heat. So the brushless one on the way, i hope, will solve this issue.

Reel Mower?

I've got a section of Bermuda in my lawn for sports.   I bought a Fiskars push reel mower and it did a good job but the area is too large.  I gave the reel mower away.   So I run my Ego mower at the lowest setting.   Much less labor but the cut isn't the same.   Thinking about the Gardenia electric reel mower but Ego-powered would be so much better.   Or, take it to the next level and electrify a California Trimmer.   Please!  There is a market here.

A reel mower with a leveling bar and half inch height adjustments. I keep scalping my Bermuda grass lawn. Self-sharpening blades, self-propelled, with bagger would be nice as well.

I want ego to make a battery powered reel mower which can cut grass lower than 1 in. And built in roller instead of wheels.
