Remote controlled lawn mower DIY 4WD

[@stanleycheng1375]

Awesome, fantastic! This DIY RC lawn mower is one of the best, even if not the best, I have seen. It effortlessly cuts tall grass, due to the 4-wheel-drive design, it manoeuvres well in difficult terrains such as slops, it weighs ideally for stability in mowing grass and moving in various directions while not over burdening the motor . Well done! I would humbly suggest you to refine, package and commercialize this fantastic mower. Thanks

[@marmasteris]

Thanks you for the high rating.

[@satishbvkumar9528]

Great work .Can i get the electronics details also?

[@quazars236]

very clean and organized... well man, you did an AWESOME MACHINE! really got me inspired of your work. thanks!

[@jeremycareystudios917]

best remote mower I've seen so far. I think I'd like to follow this and change to tracks

[@marmasteris]

Yes, tracks would be better.

[@dbc105]

Been looking at several of these mower builds and there arte things you've done here I like a lot, the tires will not chew up the lawn, the motor setup is not high dollar wheelchair/scooter parts, and it is wide. I would like to get a copy of the CAD files and anything else that applies. Good job and many thanks for sharing. DC

I appreciate your work! Well-done!

One of the best I've seen, well done!

Très très bon travail

전문가의 솜씨네요. 훌륭합니다.

[@DonnieCaves]

Love this build.

[@ModeratelyOtaku]

I like how your motors are centered rather than near the ends of the mower

[@animale8809]

Very good work, I want to build one too

[@duanejones5186]

Excellent build!

Very cool looking build 👍

Gostei muito do projeto Mas porque trocou as rodas?

[@danfreitas7905]

Best design/workmanship I've seen so far for a rotary mower. The cat likes it too. Additional footage of the build would be good to see. What horsepower motor did you use?

[@marmasteris]

Motor 15.6-18.5HP.The cat is a technical expert😀

[@eddiejimenez]

great

[@jcagnin1]

Muito bom mesmo.. Parabéns guerreiro

[@cottonwoodcreative]

is there a reason you got rid of the meaty tires? if its because of the skid steer the geometry might just be bad if you are too long and not wide enough it will result in alot of slipping around but i liked the knarley tires.

[@marmasteris]

The meaty tires tear up the lawn when turning, that's why I changed them.

[@SergeREYNIER]

Super projet ! est-ce qu'elle broie les herbes très haute? (Mulching) Si je pouvais avec les plans, merci.

[@pally15]

absolut great ! the beast...

[@ErChompy]

It's awesome, can you show the cutting parts? are blades?

[@VernLee-y9q]

Hello again , what is the wheel base center axle to axle , If you were to do it again would you make it shorter , or could it be longer and still turn ?Thanks

[@marmasteris]

Shorter would be better when making a turn. I wanted to make shorter ones, but the task was to make the cutting width 1 meter and this is determined by the length of the cutting blades. So the wheel base in this case is 930mm.If the wheelbase is extended, I think the turning will be,but not so good.

[@martinchyska1669]

Hello , Thank you for nice build , do you have any plans or material list ? How you build this wheels ? Thank you for Your answer M

[@marmasteris]

There are plans, but not complete. I redid some parts during the production process. For example, I made the frame without any plans.Motors MY1016Z3 350W 24V

[@martinchyska1669]

⁠@@marmasterisHello 😊, thank you for info about motors, but how you build this wheels , rims etc. I see you use supersprox with some adapter ? Hub ? This will help me thank you .

[@marmasteris]

@@martinchyska1669 I bought wheels, sprockets and made adapters based on them.There is a lot of turning work here. You can't do without a lathe.Most of the parts are laser cut from 5mm and 6mm steel.

[@martinchyska1669]

@@marmasterisohh that’s the little problem for me I have non of this devices :( but thank you very much for answering. I would really like to build this stuff but looks like I would need some help 😊. If you can send me some more details I will be very glad. Thank you !!!

[@rmfetter56]

Awesome content, doyou have the specs available & also the Cad drawings. What motors are you using for the 4x4 and also the 3 motors for the grass cutting blades. What is thesize and weight of your machine? Thanks for any help you can provide.

[@marmasteris]

4x4 motors DC 350W,24V.Lawnmower weight about 230kg.Grass cutting motor 18.5HP (max.power) internal-combustion engine.

[@Tinkerbell227]

I would like to get the cad plans or hire you to make me 2 of them. One as a mower. And the other with just a flat deck on top to move stuff around like car motors. A machine simular to the one at minute marker 9:42. But I want turf saver tires on the mower instead of wheel barrel tires and those bar tread tires on the mover.

hii congrats for your project, can you inform me which is the torq of your reductor for pushing the litle car ?

[@marmasteris]

DC brushed motors 4pcs AWD 24V 350W motor main technical parameters: No-load current: 2.0A Rated output power: 350W Rated speed: 3200rpm Rated torque: 1.11N.m Rated current: 12.5A Efficiency: 78% Reduction ratio: 9.78: 1 Actual speed: 330 rpm

[@nicolasakf1577]

I really appreciate your project. May I ask why have you chosen a transmission by chain instead of a direct connection of the motor to the wheel?

[@marmasteris]

I did not find such power geared motor.That's why I chose with a chain.

[@nicolasakf1577]

I understand you are using motors with a 330rpm output and reduce the speed with the chain (6/60 ? i can not count exactly the teeth...:-)) But I saw also on Aliexpress some wheelchair motors with a 75Rpm output. Do you think I could be a good idea to use this kind of motor with a direct connexion to the wheel?

[@marmasteris]

@@nicolasakf1577 Teeth 9/52,tire 4.00-8,max.speed 6km/h. I don't know the weight of your lawnmower, so I can't answer the question about wheelchairs motors. My lawnmower weighs about 250kg.

GOOD JOB

[@ayomidesalami9193]

i need access to the google drive please

[@digdilem]

I've done a few, so great to see someone else's vision. I see you're using an alternator off the shaft - when I did that with a 24v alt, I found it got extremely hot as it's constantly working at max capacity, and eventually its shaft would swell and bind against the bearings. Do you have any similar problems?

[@marmasteris]

No, there is no problem with the alternator.Alternator 24V,120A, max.consumption 70A at zero turn,so the alternator is not fully loaded.

[@digdilem]

@@marmasteris Interesting - that might be my issue - my alt is only 52a and I've got four wheelchair motors. The 5.5hp engine isn't quite powerful enough to run the alt and cut thick grass either, so I've just removed it and put a couple more batteries there for now, lasts an hour of heavy use which is a full tank of petrol too.

Good question. The batteries are under the front of the engine, a small box.LiPo 3S 5Ah 2pcs in parallel.Only for powering the starter and RC receiver.After starting, everything is powered by the alternator.
