Grasshopper or Scag mower conversion?

[pletchervaq]

I have had full size road evs and had done a quick conversion of an old craftsman rider or two so I know maybe a little. All are sold or died so I'd like to get a bigger mower for my acre instead of the temperamental robot and push mower I have.

Probably a bit crazy but I'm thinking commercial but I wonder if their 20hp is the same as a craftsman rider 20hp is? The only conversion of a commercial mower I've seen is a dixie chopper and that used a really big motor but was used in commercial duty.

I'm hoping a quick replacing the motor so wonder if I need alot more than the etek or two (one deck one transmission) like the one I used in the 42" rider I had. I think most of it is just lifespan and reliability not raw power. The machines are heavier but a bit more rugged and perhaps more efficient. There are alot of used ones in the area that look good but I don't want to get one if it'll require 120 volt 600 150 lb motor. If that is the case there are some old jd mowers I could try my luck on.

I'm looking at 42" deck or less for about an acre and a half. Split sessions are fine. I tried the ones supposidly already electric for sale like the hustler zeon and even if I wanted them local dealers won't sell or service them.

Grasshopper. Could easily use separate motors and has lots of room to mount batteries and is built for heavy duty use.

Scag. The original thought was no power would be wasted dragging me or extra parts required for a riding mower. I do worry a bit about a transmission being able to take the weight of a few batteries.
