RC Lawn Mower - RCTESTFLIGHT

[MrHichammohsen]

I love how occasionally we see the solar rover running in the background.

As a landscaper of a few years now, I'd like to point out that it might be way easier to have one large motor spin two blades instead of all the smaller blades. This will disperse the grass farther out and will have a much higher speed at the cutting edge, meaning that it would cut more effectively even when dull. It would probably save battery power too. Hope you read this.

There are 2 ways to create RC lawnmower:
1. add grass cutter to RC car
2. add RC car to grass cutter

As a farmer I can inform you that cutting thick brush in your case with such small scale you don’t use speed you use momentum with a heavy blade but if you mow your yard regularly your little rig will work good and if you look a a lawn mower the blades are angled to throw the grass away

If there ever was a YT video perfect for being sponsored by Manscaped, it would have been this one....

Super cool! I have 2 questions:
Do you have the 2 blades on the left running counter-clockwise and the 2 blades on the right running clockwise? This would help clear the cut grass out of the way better.
Do you have plans for an autonomous mower??? That would be super cool!

The concept is sound. But take it from someone who has been in lawncare for 30+ years. This would be great for a maintained lawn but you're trying to use it as a brushcutter. A few design changes I would make are as follows:
- Pitch the trailing edge of the blades to about 15 degrees. This will provide airflow to help lift un-cut blades of grass, and to blow away the cut ones.
-Take a look at most lawn tractor mower-decks which use multi-blade setups. The front of the deck is flat, while the rear is curved to hug the blades. Additionally, notice how the front of the deck increases in height toward the discharge chute. as the first blade cuts grass in its path, it will throw the grass toward the discharge chute and over the second blade down the line. The second blade also cutting ad discharging grass over the third, and so on. with each pass toward the chute, more clippings are being transported, thus needing more room to transport them. Hence the raise in the top-front edge leading to the chute. The top-rear of the deck can remain flat.
Basically, build a mower-deck using the design from a typical lawn tractor deck, while adapting it to use your 4-blade configuration.

Side note, The swing-away blades are a nice touch though. You'll see those on brush-hogs to allow the blade to deflect off of a hard object rather than breaking or bending due to being rigid.

Another idea, one that I have wanted to try for a while is a rear-discharge deck. That rise toward the cute would begin on each outer side of the front of the deck and peak in the middle.then carry rearward to a rear-facing opening. however, the leading area two sets of blades would each need to rotate toward the center so the clippings can all be transported toward the chute, and thrown rearward. However it would be good to add a wedge at the front to the deck, between the the two centermost sets of blades to prevent the right side from trying to throw it's clipping into the left side & vice-versa. Helps to think of mower decks as centrifugal fans. think of airflow or fluid dynamics, and where you want it to go.

Hope all that made sense.

One thing that holds this back is the blade geometry. Normal lawnmower blades have a angled part at the rear of the blade which causes the chopped grass pieces to fly up into the mower deck where they are bounced around until they make their way to the outsides of the mower and ejected. With completely flat blades, the mowed grass chunks fall back into the mower blades where they are rechopped and gum up the mower

A snow blower would be REALLY cool, maybe even a single stage. I made one for my 1/24 crawler and it seemed to work good on powder snow.

I'm not able to mow my lawn due to a stroke and ever since I wanted to build a robot lawn mower. Hence the reason I'm trying to learn how via DIY videos. I'm glad I came across your video. I'm going to order the Hobbywing QuicRun Fusion Brushless System Motor & ESC 2-in-1 1200Kv / 1800Kv 540 Waterproof For RC Crawler you suggested. I was quite impressed on how well your mower performed. Thanks for the video.

[devanallesside]

you should make an autonomous rover that charges a lipo with its solar panels to activate the cutters once a week, with that you should be able to make some cool sattelite art in your field after a few months

Couple things i noticed, (long time landscaper) I would suggest taking a look at commercial lawn mower decks. Look at the grass "pathway" tothe exit shoot on the right. They purposely have it all going to the same exit point and use the front edge of the deck as a channel. The smoother the spot that the grass travels at, the better it will expel. Also would suggest angling the deck upward in the front. Sounds odd, but I think if you had say 15% angle(?) on it it would help. So you would essentially set the rear at the desired cut height. This allows the front side to start cutting at a slight higher cut height and finish lower in the back. May help, and really just a thought.

One really big thing i can say is, even with a $25k commercial mower, they dont easily go through grass above 5-6" let alone if wet. Starting at like a 4" cut height would help a lot.

Also what if instead of exacto blades, try it more like a weed wacker?

[usa_dobson]

Hear me out.... Autonomous weed-eater that circles your properties border keeping the weeds in check ;)

Greetings from Finland!

I think it would make a ton of difference if the blades weren't heading straight into the direction of movement, but to position them in a V-configuration like an old-fashioned snow plow. Then also implementing clockwise and counter-clockwise movement to reduce the amount of built up grass.

Really cool project!

[IAmFromTheTop]

I wonder if reversing the rotation on half the cutting heads would help feed the grass out and prevent clogging.

[Fswiergul]

This is a super cool idea. It'd be good for disabled people who can't use a push mower or transfer easy into a riding mower. Heck, I'm in a power wheelchair and I'd totally use something like this to help elderly or other disabled people by mowing their lawns people's yards. You can have fun using an RC car AND be productive!

I know they make grass cutting but those are at least $1000 and for small yards, it might be more beneficial to have a human that can navigate weird obstacles anyhow.

You're channel is both entertaining but also very eye opening to what's possible

[imchris]

you need to add a auger on top of the blades in front and one behind the blades in the shroud. look at hay mowers for examples. the augers clear all the buildups

[ukandrew]

Yes revisit this project please. Great idea. Whilst watching it seems the biggest problem is with grass cuttings building up around the cutters. I was wondering if something like a hoovering system could suck the cuttings away and blast them out evenly behind the machine? Once this machine has been perfected your next task will be to automate it. Then you can relax with your tea and a scone whilst watching the show.
