If the garden machine will be geared for a top speed of around walking speed and used only on flat ground then two 350 Watt gear motors would have plenty of power to do the job, and if it needs to climb hills or grades then two 650 Watt motors would be more suitable.
Please let us know if you have any questions.
We carry an 11 tooth motor sprocket for 1/2"x1/8" chain for our 36 Volt 600 Watt gear motor and we have freewheels that work with our larger 1/2"x1/8" 5-hole sprockets so that may be the direction to look towards instead of the 650 Watt gear motor.
What are your thoughts on throttles? Two thumb throttles, or???
Hi Walker - The motor could be 24, 36, or 48 Volt. The Watts rating of the motor determines its power so that is the determining factor in deciding what motor to use. For a cart with 4.5 MPH top speed hauling 250 pounds a 350 Watt motor would work well for terrain that is flat to gently sloped, and a 600 or 650 Watt motor would work well for flat to steeply sloped and for going through sand and mud. For extreme duty, we also have a 48 Volt 1000 Watt motor which would work well for very steep slopes and deep sand.
A 45-minute runtime is no problem at all and once the motors Voltage and Watt rating have been selected then we can help with determining what size battery pack would provide that amount of runtime.
If you are interested we could also make a kit which has labeled matching connectors on all of the parts for easy plug-and-play electrical installation.
Please let us know your thoughts on which size motor would be best for the project and let us know if you have any questions and we can take it from there.
The names were not the reason for the late reply, I have just been away from the forum for a while. It takes us an hour or longer to make a link for a kit so that is not something we could do over the phone. We can make a kit here though and then post a link to it.
I am going to start a parts list to help build the kit:
Could you please review the questions above that are marked in red and let me know which parts to include with the kit?
Also if there are any parts in the list that you would like changed then please let me know.
Please let me know if you have any questions. Thank you.
