Evguy 550 #1 Posted April 19, 2022 Something different, neighbor was trashing a jd mower with blown engine. During Covid downtime I put this together to move trailers etc. Other than pulley and belt, I had the parts in the shop. 3 8 Share this post Link to post Share on other sites
SylvanLakeWH 24,175 #2 Posted April 19, 2022 Very cool! How about some more details…? Motor type. Voltage. Battery type. Connecting motor to frame system… 1 Share this post Link to post Share on other sites

Connecting motor to frame system… The motor was salvaged from a powered pallet jack, had it for a decade, I machined the gear off the shaft and fitted a pulley. the voltage for motor was 12v but I increased it to 16 to get enough rpm. batteries are lithium 3.5 volt. I simply made a aluminum plate to widen surface area and fit motor and batteries to the frame. It is inefficient due to motor, but has a lot of torque with hydraulic drive, enough to roll a tire off rim while pulling a trailer. I probably get 1/2 hour running time. 1 1 Share this post Link to post Share on other sites

Not something I'd have a need to build right away but the technology and the work behind it is pretty fascinating. If you start a build thread please do feel free to give my name a mention so I get called into it... 2 Share this post Link to post Share on other sites

Biggest problem I forsee... is cost of replacing those batteries over their... relatively short lifespan. In 10 years... you may look back and wonder if it was worth it...

Might need a butt-load more AH for mowing though... depending on land size. Don I’ve done the math with estimated numbers and other unknowns probably won’t finish in one charge. But close. It takes 50 minutes with 60 inch ztr , but WH cut is smaller and it’s slower. Share this post Link to post Share on other sites

No, seriously, I would imagine, the more load (i.e. taller grass, thicker grass) it would not last as long. BUT... GOSH you would look cool out there for however long it lasted on a John Deere garden tractor... mowing... in SILENCE... HAHAHAHAHAHAHA Don Share this post Link to post Share on other sites
