It looks like your trying to build a safe machine!   What you are building would be a GP under the USLMRA rules.  Single cylinder governed at 3650 RPM's.

You have a good start. 

But have a way to go yet. 

First you need  safety teather.   So when you fall off the mower shuts down.

You need a different front axle.  The stocker WILL brake at any speed over stock.  You WILL get hurt when it brakes.

You need better brakes.  The stock brakes won't stop the mower at speeds over stock for long.  When they fail you WILL get hurt.

You need to upgrade the steering and the linkage.  It WILL fall apart at speeds faster than stock.

Good start!   Keep going!!

Thanks for the tips and suggestions. I will certainly take all to heart. Its a v twin and i do plan on removing the governor. I still have an active original seat kill switch. In fact all safety switches are in tact. Except the deck engaged switch. Next will probably be front axle fabrication and frame brace.  The front axle on this machine does seem pretty beefy though. But cant turn down great advice. Then on to the steering that should be easy enough. I have no clue where to start on brakes. Ill take brake tips for days.

I thought you said it was a single in the vid.   What kind of twin?    Briggs intek I assume. 

Don't remove the governor until you get a billet flywheel.

The seat switch is junk.  Put a good kill switch teather on it.  They are cheap and will clean up your wiring in the long run. 

Better brakes on a transaxle take a bit more work but the parts are readily avalible.

Its a 24hp Intek.

Ill definitely add the teather kill.

After a good look at my axle. It is cast iron. Still not tough enough?

As for brakes. I was thinking of welding a disc to the current disc and add a mechanical caliper. But im not certain that is the best route.

Don't pull the governor until you get a billet flywheel and pull the parts out of the internals.  Bad things will happen if you do.

I'm guessing your transaxle is cast aluminum.    It will be fine until it explodes.  And it will behind that twin.

You need axle mounted mounted brakes.  The stock brake is junk.  It will never be an effective brake.

Get a brake hat and rotor.  A good hydraulic brake is cheap and can be found used for under $40.

I have bent and broken some very high quality 1/2" rod ends before. If I can do that, that front axle will not last.

This is the tether I always used. After issues with the "button" style, I went to this and never had a switch failure.https://www.summitracing.com/parts/poa-a040021?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-pro-armor&gclid=CjwKEAjwqZ7GBRC1srKSv9TV_iwSJADKTjaD33Lz1QoV1Gkkgt1HJ-Me1dsMc8KiqPAy_fGyL08g4hoCJTzw_wcB&ibanner=MobileSwitchNo

You will also want to upgrade the steering shaft and wheel, Those plastic ones wont last..

I like that switch, thanks! Thats definitely the one im going with.

Im thinking front axle and steering will be my next project. Maybe add front disc brakes since its all from scratch.

How did you break those 1/2 in rods? That couldn't have been easy.
