Probably could, you would have to design a radio remote control interface that mimicked the input control of a joy stick. If you run across such a design, please post a link, I would be interested in such a design. The sabertooth motor controller that I used is the simplest way to implement RC control you can use.

I have approximately $2000 invested in this mower.

Hi jmoore, see the comment starting with “Hi GrapePie” in the “End of Mowing Season Review”. I used a 24V 40Amp alternator that I got on Amazon, here is the link www.amazon.com/Alternator-1101285-1102348-1102379-AT130930/dp/B01NCI3Z2S/ref=sr_1_1?crid=33V939IVZEYFN&dib=eyJ2IjoiMSJ9.oRMY4qghD6UaHHgHDKZhoMvQbVIyYxA-34DBxF-6hBGQSpndCkW3er5TPUbOnasVzKzf-ZN-FWTt1CU0bcmsUSPIeRN5r-wyQMcANXyNk9WnzmqRT4Qk91Q5bGPalc_cngjk6pkR2-e8fXWqKXDXgXPhQu_Q4ZDeHVgv6Yu9YKa3vrUiLN2X8ULxYAMU9BG00QnqkpzOr1yLsiIySpatUNE4dxPQMS1hxbXuLTAuGBXGNMNbtCa_I78SlD59RJ00IhEOYGAdOe41mVPWH7Pu8lZmoDQSmbO13I5AHnJSj5c.cKkO7nehYoGLxduCi4NiweCYTfgWECqLjSNPblZfUpo&dib_tag=se&keywords=Roll+over+image+to+zoom+in+New+24V+1-Wire+Heavy+Duty+Alternator+Compatible+With+Case+L59901%2C+1101285%2C+1102348%2C+1102379%2C+AT130930%2C+TY6752%2C+ADR0392%2C+40012228%2C+40012228R%2C+40012491&qid=1713570806&sprefix=roll+over+image+to+zoom+in+new+24v+1-wire+heavy+duty+alternator+compatible+with+case+l59901%2C+1101285%2C+1102348%2C+1102379%2C+at130930%2C+ty6752%2C+adr0392%2C+40012228%2C+40012228r%2C+40012491%2Caps%2C181&sr=8-1

Thank you Sir!

Hi what’s up, unfortunately I do not have the time to devote to an another build.

@@giterbilt5146 Thank you for coming back to me, would you be able to provide a list of part, only need to motor for the wheels, and the electrics, I downloaded your plans and working on a frame :) will show you my progress soon thank you love this project.

@@whatsup3358 I wish I did have a parts lists that would help people like you with their build. Gregor Kobetic has a video on motors that may be helpful, plus some great information on building a RC Mower. The biggest hurdle for most people is wheel hubs that attach directly to the motors. This was a big problem for me also. ​​⁠ Here is a link to motor wheel combination that could work. These are brushed motors that will connect directly to a sabertooth motor controller. The joystick is not needed. www.aliexpress.us/item/3256806084232655.html?src=google&src=google&albch=shopping&acnt=708-803-3821&slnk=&plac=&mtctp=&albbt=Google_7_shopping&albagn=888888&isSmbAutoCall=false&needSmbHouyi=false&albcp=19235666539&albag=&trgt=&crea=en3256806084232655&netw=x&device=c&albpg=&albpd=en3256806084232655&gad_source=1&aff_fcid=6dacd2df1f8c4fc4b066e92bfa034ba3-1714222836070-09136-UneMJZVf&aff_fsk=UneMJZVf&aff_platform=aaf&sk=UneMJZVf&aff_trace_key=6dacd2df1f8c4fc4b066e92bfa034ba3-1714222836070-09136-UneMJZVf&terminal_id=66749f54600d4b4c9fae0da09439ac79&afSmartRedirect=y&gatewayAdapt=glo2usa. I have schematics for the electronics on my google drive which indicate electronic components used. Good luck with your project, I look forward to seeing the finished project.

Hi David, you are absolutely correct! The line to the left of diode should not be there. Thanks for bringing this to my attention. I will update the schematic when I get a chance. The circle with an A in it is a symbol for an Alternator.

Schematic updated. Thanks again for your help.

@@giterbilt5146 oh thanks for the reply. Kind regards David

Sorry. I have another question before I turn the power on. I do not understand why each motor's positive and negative wires do not Return to the same Controller in all cases? For example left Motor front takes it's positive from positive on the left Hand sabretooth but it's negative returns to the negative on the right hand sabretooth. Why does it not simply return to the left sabretooth? The same question applies in all 4 cases. If I had not seen your Diagramm I would have driven the front left Motor from the Pos and neg on the left sabretooth and the left rear motor from the same pair of Pos and neg terminal on the right hand sabretooth. And ditto for the other side. If you find time to answer I would greatly appreciate it. Thank you Kind regards David

I don’t know what the Veterans Administration was putting in my medication when I made this drawing, but I sure screwed it up. New medications new wiring diagram. Simpler to read. God I hope it’s right this time. S1 on each controller drives the front motors, S2 drives the rear set. In this diagram I show the rear motors in reverse polarity because they are mounted in the opposite direction from the front on my chassis. Again, I apologize for the confusion and thank you greatly for pointing this out. The updated diagram is on my google shared drive. If you find any other mistakes, please let me know.

My criteria was a single belt pulley, single wire system, 24V and cheap. I have an explanation of the alternator performance in the comments for the “End of mowing season review video”.

@@giterbilt5146 thank you for the reply. I found that comment thread and asked a question there

Hi Dustin, I made the clamps out of 5/8 inch bolts welded to Harbor Freight clamps. There are multiple videos on how to cut the clamp and weld on the bolt. The 1-2-3 and 2-4-6 blocks I got on Amazon.

That’s a heck of a deal! The legs are free. I’m sure they corrected the problem that I had. All the other reviews of these table do not mention it. The tables @ $500 alone are worth it. Hard to find a 4’x6’ cast iron table setup for $2K.

Thanks for watching!

The information you seek is linked in the description.

Thanks for the compliment. After mowing about 1 .5 hours and 1/4 mile round trip to my shop, the batteries are 1.5 volts less than full capacity. I recharge after mowing with a 24V battery charger which I connect to the positive and negative terminals on the alternator. It takes about 15 minutes to fully recharge. The alternator only extends the run time, it will not charge more than the average discharge rate of the electric motors. I have stopped mowing and let the mower run to recharge the batteries, takes less time than the charger, it charges rather quickly.

@@giterbilt5146 Thanks for your info and super quick reply!

Hi delasjw, I helped dannythoms solve a similar problem. Read through his comments and my troubleshooting reply’s on my Four Wheel Drive Remote Controlled Control Mower Build video. I hope it puts you on the right track to solving your problem.

Thank for the comment! The mower I used is discontinued. The specs are similar to the 21442. Good luck with your project.

I show how it’s done in my build video, here’s the link th-cam.com/video/ZIBI8zOR1_M/w-d-xo.htmlsi=oxBltOtT3OXaUNJY

Wheel rims and original tires are from Harbor Freight (discontinued).

There are 4 counter sunk holes on the top for each leg. The Allen head bolts are flush with the table top. Two of the four counter sunk bolts are shown at 1:29 in the video.

The motors are connected parallel. Each Sabertooth channel controls two motors. The control signal from a receiver channel is assigned to controller channel. S1 and S2 each drive two motors. Watch “Mow Power” on my channel for an explanation on how this is wired. There is hyperlink in the description to the wiring diagram.

No

The mower has 4 wheel chair motors with attached wheels.

Gracias a ti

Wheel rims and original tires Harbor Freight (discontinued). Carlisle tire upgrade from Amazon.

I looked at SSR but was afraid of the heat they generated. The Sabertooth controller is heat sensitive. On 95 + degree days it will shut itself down due to heat inside the case. I did not think about externally mounting the SSR AND heat sink. I’m kind of old school and went with what I was comfortable working with. If you have a recommendation, please let me know, I might use it when I add another motor controller instead of a using a contactor. Thanks for the comment!

@@giterbilt5146 I have since learned that motor controller/motors are an inductive load and SSR are only rated at 20% of their rating for inductive loads. So if you get a 400A solid state relay, it is only truly rated for 400x20%=80A. In my application I'm using a Sabertooth 2x60 and using an 80A effective relay is not ideal. I did some tests anyway and in my application I was not going over 60A from battery but still the relay was extremely hot. I would caution anyone against using SSR with Sabertooth or any motors.

Hi Michael, unfortunately I did not video the modifications I made to the rims for the bolt pattern on the 5 bolt wheel chair motor hubs. The rims I used were split rims with four holes that bolted the halves together. I used a milling machine and a rotary table to drill the five holes to match bolt pattern of the wheel chair motor hubs. I have two videos from others that show what is required. For measuring the wheel chair motor hub pattern th-cam.com/users/shorts73c_wgt4vpM?si=G9qIVdy5Dxn8_kVs. And what is involved in drilling the new pattern on the rims th-cam.com/video/pPp61MqjOds/w-d-xo.htmlsi=gpH6QTfnx_RtGPbC. If you do not have the equipment to do this, a local machine shop can handle this for you.

Thank you

Thanks! Yes i did. The tire change only increased the deck height by 1”. The mower deck is fully height adjustable.

No they are parallel. Each Sabertooth controls two motors. The control signal from a receiver channel is sent simultaneously to both controllers via split signal wire. S1 and S2 on both controllers receive the same signal input from their respective transmitter/receiver channels.

Schottky Barrier Rectifier Diodes 5A 60V

@@giterbilt5146 ok thanks Can I get your opinion?I got these laying around. I have sf54 5a 200v do you think they will work fine ?

I have the same set up as you also inspired by you as well.

Your diode is probably a better choice for the coil circuit. Dimension Engineering specified 5A 60v diode for the motor controller help.dimensionengineering.com/knowledgebase.php?article=7. I picked the Schottky diode because I was taught (40 years ago) they provide the best reverse current protection. I used it for the coil energizer because I had 99 on hand. I would think your diodes would work for both.

I use two Weize 12V 35AH Battery Rechargeable SLA Deep Cycle AGM in Series for 24V. a.co/d/hDJ6Ei0

I had thought about it. Weight, run time, price and the ability to cut taller thicker grass was the consideration for my choice for using a gas engine.

I had the same problem. I searched online for hours and only found original wheel chair wheels. In the end I had to drill the bolt hole pattern myself using a rotary table on my milling machine. The wheels I used are no longer available at Harbor Freight. I was going to use go cart hubs before I found the wheels I used. Once you have acquired the wheels, take them and the motor to a machine shop and they can drill the correct hole pattern.

Thanks for the compliment.

Thanks for the tip!

Yes it is.

@@giterbilt5146 What was your thought process when deciding to purchase a dual motor driver vs single for the actuator? Was there a suitable single driver controller for a RC setup?

@@H_Learns I got the dual for future need for implements attached to the tool bar that might need 2 axis movement. Cytron makes a single motor controller for RC.

Oh yeah, as I mention in the video it is flat to +- 0.010. These are really good tables.
