New project mower and backup engine

In the past 2 weeks I've picked up another build project I'm going to turn into a more tame trail machine for my daughter and I also was in the right place at the right time for a backup engine to fall my way. It's a long block but its perfect for my plans on my primary mud mower. Ultimately I'm going to modify this block and save the current mill as the backup block

Finished my second machine. Decided to make it a snow plow as well since it's very stout on traction. Currently has the dabbed up blade on it in the pic. Used it to push a bunch of landscape dirt a around the yard. No problems. It's currently my push busted riders around the yard or drag them vehicle but once I get my main machine going it's my kids follow Dad through the muck toy as well.

What kinda engine did you get? Is that like a 13hp?

Kohler 7000 series. More like a 20hp engine. I've got it disassembled at the moment so I can upgrade the valve train in it. Going to take a setting at making a longer ticket arm ratio for increasing the stock can lift and duration.
