Yea, I know its not a CC.....It's a Toro. I'm converting it to electric. I'll document the whole procedure and why I used what I used in an article when it's done. For now a tease....

I'm shocked at all I accomplished yesterday. I started at 10am with a complete Toro riding lawnmower.....Had all this done by 5PM!
Pulled the engine and anything else associated with it. Removed all the mower deck attachments. This tractor will have a front mounted mower with its own electric motor to make it easier to access areas of my property.
Found a piece of steel in my scrap pile to mount the motor. My DRO milling machine made locating the mounting holes a snap.
While the paint was drying on the mounting plate, I removed all the pulleys and wire brushed the surface rust, checked bearings and reinstalled
I realized that if I widened the existing, under-seat battery compartment by 1", and raised the seat 3/4 inch, I could mount two of the four batteries in the rear. Great weight distribution. A few pieces of angle iron and a welder....done!
Need to fabricate a front battery rack, do some wiring, install batteries and we are mobile!
This project started with a John Deere 214 that I bought without a motor. I purchased a Honda GX390 gas engine to power it but then decided on electric. As I was getting ready to fabricate a mount for the electric motor in the 214, my son-in-law offered this pristine condition Toro that had a non-running engine. The Toro seemed much easier to mount the motor and being a smaller, lighter tractor will suit my lawn mowing needs better.
I posted the Honda engine for sale on Facebook Marketplace and a fellow drove three hours to buy it. (Going to use it on a homebuilt bandsaw mill) While at my house he saw the none running 20hp Toro engine and bought that too! Nice!
Now I need to purchase 4, 12V Group 31 batteries for the 48v DC motor.......
Stay tuned!

Welded up a couple holders for the four batteries. Two in the front, two in the back.....I haven't bought batteries yet, but I just had to see if it works...Pulled the two 12V deep cycle batteries out of my RV and ran the motor on 24V.....IT'S ALIVE!
Ran great!.....Transmission controls speed perfectly. Brakes work....Good to go!
Tomorrow I'll source batteries, put the wheels and tires back on, and drive it around!

Is there enough space between the motor and the batteries that will be sitting on top of it so that the motor still can get airflow through it?

We shall see! I'm attaching a remote LCD thermometer to the motor so I can monitor heat. I have a 6" 12v computer fan that draws very little current that I'll install if things get dicy. It will get its 12v from a DC to DC converter (48v down to 12V/30a)
There is a 1" space between the batteries and the batteries are an inch above the motor.
If none of this works, there is room in front of the motor for the batteries. I mounted them where they are to move as much weight off the front axle as possible. My concern is this is a "Lawn Tractor" not a "Garden Tractor".....It's a lightweight. The batteries are 360#....The motor was 92#, full gas tank 16#, starting battery 35#, Everything else associated with motor that was removed 25#... = 168#....So I'm adding 192# to the tractor. I weight 185#.....That's a lot of weight for those little tires and axles.
The mower deck will be mounted off the front, so when raised, that a whole lot of weight on the front axle.....
I have a John Deere 214 sitting nearby that ultimately all of this might move to. But for my first attempt at an EV, this Toro was a MUCH easier conversion......I'm learning lots as I move along.

I drove two hours to NH to pick up four 12V, AGM, 100aH, Group 31, Deep Cycle batteries from Sams Club....At $179 each, easily the best deal on planet earth for quality deep cycle batteries......And no sales tax in New Hampshire!
I mounted the contactor on an aluminum bracket I fabricated
Cut a hole in the dask for the battery monitor
And mounted the "Oh Sh#T" deadman switch next to the old ignition switch which I intend to use as the main power switch.
Just waiting for some 2/0 welding cable and copper lugs to show up from AMAZON and I can wire this thing up and start using it around my propertty.

While waiting for wire, I changed the belts and gave the chassis a good grease and lube job. Plugged a small leak in one of the front tires......

While waiting for my 2/0 wire to show up , I figured I'd do most of the 12v/secondary wiring and fabricate a few battery tie down straps. I also had a bit of #2 wire that I used for the less than 6" runs to the various components. I was concerned that I wouldn't be able to bend the 2/0 wire as needed. I'll have to keep an eye on them to see if they get too hot.

It RUNS!...
First test of my Toro Lawn Tractor conversion to electric motor. Only running it on 24V to be safe. Will attach the other two batteries for 48V tomorrow.
Something is rubbing making that clicking sound. Will figure that out.
Has tons of power even on 24V. Put it up against a fence post and it just sat there spinning the tires on asphalt. With over 400# on the rear tires!
Too much fun!

That’s awesome! I’ve thought of converting a 582 with a bad engine my dad has to electric. Thanks for inspiration! Looking forward to see more of your electric conversion.
