RBT repower with Fuel Injected Kohler ???

Recommended Posts


My winter project is the repower of an Allis 918 (Sovereign 18) - and I am sticking with Kohler.

I could go with the old-standard Kohler CH-18 spec 62638 (now PACH621-3013) at approximately $1650.

However, I see that an EFI Kohler - like the ECH630-spec 3007 can be had for $150 less.  

Has anyone tried putting an EFI Kohler into a large frame RBT?

Some of the feedback received on zero turns sold at work with Kohler EFI's was that they seemed lower on HP than carbureted equivalents. 

Fuel milage was reported to be much improved.  I was a teck in a L&G shop when the FI was introduced.  The Kohler rep said the engines ran much leaner that the carb version yet had the "same power".  The FI was doing a good job of fuel management.   I had no personal experience with the FI engines so can't really comment on "power".

We had carb Kohlers in our mowers and when replaced they gave us EFI engines.

First off they seem easier on fuel, definitely start much better especially in cold weather, I'ld say much easier maintanence. Just my $.02

Should say to a lot easier on plugs, I was replacing plugs in carb engines quite freqeuntly and have yet to in the EFI engines.

You will have to find a place to mount the ECM.

So ... there is an Engine Control Module separate from the engine?  And this ECM is probably sold separate from the Kohler ECH630 replacement engine?

I was told by a guy I purchased my 2nd Sovereign from, he put a FI Command in a Sovereign and had to mount the ECU to side ( I think the LH side under the lift lever). He also told me the ECU was made by Fiat.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
