Wouldn’t my electric gt1800 be a repower? 😁

An exemplary one, I believe!

Gt1800 workhorse to Electric power

 

No horses were harmed in this conversation, original mounting holes were used, no cutting.

While not for everyone, this is a conversion to battery electric power, using recycled batteries and electric parts.

I used a permanent magnet motor sourced online, 11.5 continuous 14 peak. 3900rpm

 I took measurements and positioned the motor to match the broken engine I removed.

 I found a thrust bearing for PTO for using the original PTO.

 Control of motor is a contactor that provides power with no speed control.

That is sweet! Those extra RPMs should perk the mower deck up. 

 

Be sure to give us some details on the motor and batteries. I'm curious what kind of run time you get from that setup.

Here’s a link to the complete build.

So, a little more information for any who may be considering this swap. I got the engine and have begun to mock it up and see where any problem areas may be. To my great surprise this thing is about as close to a plug and play as one might ask for lol. I had to remove the original "riser plate" my name for it. I replaced it with three 1/4" x 1 1/4 " x the width of the rails and the stack gives me exactly 3/4" lift for the engine. This got the height right on the money.  The bracket to mount the clutch assembly to the engine is almost dead on and bolts to the new engine in the same location with the slightest bit of grinding on the bracket in the bottom center of the bolt locations. This clears a little bit of raised casting on the engine. I have the belt in line and on the pully and it just sits in almost perfect alignment with its own weight and one bolt on the bracket holding it all. I have to finish locating and drilling the mounting holes and I may be up and running. The only thing that needs to be addressed to shut the hood is the air box needs to be replaced with something else. I see some options on the web. Some pictures to show the fitment for any interested parties.

I've been actively resisting the whole "electrification" trend. E-series notwithstanding, because they are awesome.

 

That being said, your repower looks great, and well thought out. Very nice!

I’m not a believer that it will fix the planet, I just like building them, mowers are a new chapter. 
It is nice not running to get fuel for the yard though….

Man, ain't that the truth.  I have had a battery powered push mower now for maybe 5 years.  I mow my front yard with it and the trim around the back before breaking out the Horse to finish the rest of the yard.  You couldn't pay me enough to go back to a gas push mower.

I have every intention of building an electrified Horse one of these days as well.  I've been on the lookout for a proper donor chassis with a hydro, but haven't come up with the right one yet.  Seems like all the ones I find are either "too nice" to tear apart, or so far gone that they aren't worth the effort.  I love seeing all the repowers

Here is my 1960 Suburban 400 repowered with a Predator 212 non-hemi version. After removing the factory tank and exhaust from the engine and modifying the stock air filter lid, the engine went right in without issue. The mounting bolt holes are spot on. The hole spacing for the stock belt guard was perfect.  

For the exhaust I used a stainless steel flange to 3/4" NPT adapter purchased from eBay to convert the exhaust from the stock two bolt flange type to NPT, the adapter also came with the muffler I used...was around $45. From there I just used standard black steel 3/4" NPT fittings and I believe a 12" section of pipe to get the exhaust to the front. I did have to use a 1" spacer between the exhaust pipe and clamping surface because the was a larger gap than with the original K91 engine exhaust. 

The exhaust shield I used is actually a reproduction unit purchased again from eBay for roughly $40.

The stock airbox was modified by cutting off the top leaving the section that actually holds the filter in, and the using sheet metal sealed with black RTV then pop riveted to the stock filter top. This particular air filter draws its air from the bottom. I wanted a more factory looking filter box than using an exposed pod filter that would be affected by the elements. 

In place of the stock fuel tank I used sheet metal to cover the governor of the engine and to give a more factory appearance. 

Other than that I hooked up the fuel system and throttle cable. Nothing special or specific needed other than longer fuel line.

This engine setup is smoother, more powerful and easier to start.

What an absolutely beautiful machine you have there @benjiboo! Just absolutely beautiful. Well done, you should be very proud.

This reminds me that at some point I need to replace the PT wood 2x4's that some PO used to mount the Honda GX610 on my GT-1848 with something more... reliable and solid.   I don't know how old these are but they're looking a bit tired. I had thought about using square tube steel stock but stacking plates to get the right height seems like a much better idea.   Or maybe a combination of the 2.

That is a rather big engine to be mounted on wood. I've seen people use plates with washers in between to get the correct height.

 

Having said that... I do have a spare engine mounting plate laying around that came off the 800 Special. Not sure if that would help you or not... but I think I have some pictures of it somewhere.

 

Also, maybe start a thread on it, maybe some of the other guys on here have some ideas

I'll take a look and take some measurements when it gets a bit warmer... like, maybe Monday when it will be above 20*   The offer is appreciated, but I can probably get a piece of 1" square tube and some plates at Rural King next time I pop in there, which is usually once or twice a week.  I was just thinking, I should at least do this before I repair and paint my hood though. I'd hate to have that engine shake loose and bang up a freshly re-done hood, among whatever other damage could result from that. 

 

Oh, and when I finish the stack on this one, I'll post some pictures either here or in another related thread. That also will happen soon after it warms up a bit.
