Wow I am seriously impressed. Surprised it could get traction without wheel weights. I finally scored myself an old 730 similar to yours with a seized motor and hope to follow in your footsteps (have read your forum posts and walkthrough, quite good info). Just need to figure out a source for motor and controller
@@reidallaway The old 730 sits still and awaits its transplant. Not made it to the priority list sadly and still no motor or controller. Someday, someday. Your work still inspires though! Thanks for checking in
@@fouroakfarm glad to hear you've still kept the dream alive. Sometimes it can be a couple years before the stars align for a given project. Get in touch by e-mail via our farm (www.fermetournesol.qc.ca) if you ever need help figuring stuff out or locating affordable parts for the conversion.
Greetings. I can’t sing the praises of the BCS tractor enough, but adding the electric drive takes it to a whole other level. Wondering if you’re considering offering the plans to convert?
I got your message and sent you an e-mail today Peter. I do hope to make and sell conversion tools/kits eventually but I'm short that 8th day in the week for the time being.
That's exciting that they're saying 2024. They've been saying that something is "coming soon" for several years and I'm excited to see what their engineers can do with all the resources at their disposal.
That soil appears to have very little hardpan or compaction. In conventional farming tillage the HP requirement is around 70 hp per shank on a disc ripper. That little gem is just too cool. Cheers
I would agree with that. A 7 shank ripper behind 490 hp is a sure thing, until the wheels or tracks slip. My LML Duramax is purportedly 490 hp. Seems a bit nonsensical to me. you can put all the hp you want in a lawn mower, but if it can't apply that power to traction, it equates to urinating toward a headwind.
With rototiller, and also with our recently acquired 65cm flail mower, it is possible to get up to 5000W or even a bit more instantaneous power output. However, typical power demand for rototiller or power harrow is normally much lower (1500-3000W) as we're usually doing final bed preparation in greenhouses where the soil is relatively loose.
Need some help. So I have a similar tractor to BCS and not too long ago its engine died (most likely something with valves, cus no compression and so on) and now I have an opportunity to convert it to electric but I don't know how powerful should the motor be. Wana make 24V system so that I could use batteries somewhere else. Currently have two options 72V 100A or 24V 119A brushed DC motors. I could buy a pallet lift thingy but the cheapest I could find was 450€ and for something I will be dissembling that's a bit much. Any suggestions about the motor? What are the specs I should be looking for? Any help is appreciated
Hi Audrius. If you have a motor rated for 119A at 24V as a continous power rating that's probably not a bad candidate for a small to medium-sized BCS. Maybe too small for an 853 or one of the other big ones if you have power-hungry attachments. If the motor can handle 120A continuous it can probably handle 300A for a few seconds and 200A intermittent. This is about the kind of peak power demand I see with mine though most of the time it's only 40 to 60A at 24V. I've only managed to go over 200A very briefly on a couple occasions so I think an average of 80-100A at 24V is pretty good. Tell me more about the motor if you're unsure.
@@reidallaway Just found "Still EGV-S14" 2006 parts for sale, but after looking at the datasheet (traction motor 1.2kW and hoist motor 3kW) motors seem a little bit too weak and it's a bit odd that main drive motor is 2.5 times weaker than the pumps motor. So if I were to use the pumps motor I wouldn't be able to use original speed controller, so it's the same as buying the motor seperatly. Hmm... Got stuck again :)
@@audriusradziunas5451 yes the traction motor on small pallet trucks is often only about 1.5kW. You may need to look at small forklifts to find a suitable used traction motor. Pump motors are often impossible to use because the output shaft is frequently coupled very closely to the pump with tang or female splined coupler that makes these motors pretty near impossible to reuse cheaply.
I think the current eGX is a replacement for the 150cc motor whereas the BCS tractors this size and up use the 340 and 390cc models. Still a ways to go but there aren't any technical hurdles to making a conversion kit for BCS or a stock electric model. It's probably economics and dealer support that prevent it to date
The video kinda exaggerates the noise. It's all gears in oil and a little bit of brush noise from the DC motor. Really it's not even mildly annoying but it's definitely not silent.
Look at the 4 year old videos where he's building it... IIRC it's 10 kW motor running at only 24 volts so not using it's capability. He's pulling rarely more than 200 amps max, so ~8 hp peak as he says above in response to Audrius.
I know a bit about engines. the Honda GX340 that was on here originally was a really great engine but I took it off shelved it. After a year or two I sold it and I'll never use one again. Using an electric motor for traction applications is just that much better. Yes batteries are heavier and bulkier than fuel but you can accommodate that with good design and end up with a machine that simply works better in every regard. Our farm is almost 20 people and maybe 10 of them use this tractor from time to time. NOBODY would want me convert it back to a gas engine after operating it under electric power. That's enough real-world confirmation for me.

This is such a great project! I remember seeing a ton of these style devices in Cambodia that were gas powered.
Super super impessed, I foresee much drooling! An important contribution for all users, totally rocks
Inspiring! Have pointed our local wildlife trust to your excellent work. Let’s see if we can’t replicate this over the pond in the UK…

any progress on your conversion dreams for BCS? It's almost that time of year

A commercial from BCS told me they will sale an electric one for 2024. Waiting to see

That soil appears to have very little hardpan or compaction. In conventional farming tillage the HP requirement is around 70 hp per shank on a disc ripper. That little gem is just too cool. Cheers
I would have expected torque/shank, HP/shank seems highly dependent on gear ratio, etc?

ça décape, c'est classe comme machinerie ^^
This is incredible! I'd love a BCS but don't want to work with a Gas instrument. Do you have plans for this?
No plans per se but lots of info about the conversion in other videos on this same account.
Hello. I wonder how many watts is rototiller or power harrow requires since you mentioned ripper is lower than those. Thanks for good work and video!

How you did that?
I wonder if BCS will offer this as a factory option with the new honda eGX motors

Noisier in operation than i thought it would be.

Very ridículous...they make motors to go on them...don't weigh.half as much as those dam battery...
