Repower old Equipment

John Deere 425 Category

Available replacement parts listed below, please click product number to view more information about each replacement part.

Original Model: Kawasaki FD620D

This tractor does not use the front shaft.

Most of these tractors were carbureted, if yours is carbureted you can use the 386447-JD425 kit. This is a 23hp Air Cooled Vanguard based kit

If yours is fuel injected, we do not currently have an option for you.

We have discontinued using Kawasai engines for repower kits on this unit, due to the John Deere and Kawasaki agreement which voids the warranty on any Kawasaki engine not produced exclusively for John Deere by Kawasaki.

If you have a 4-Wheel Steer tractor you may have to notch out a small area on the left side mounting bracket for it to clear the gearbox

General Disclaimer

While we may have sold many engines listed above to be used for a John Deere 425 Category, we are NOT claiming these are exact replacements unless the product notes explicitly say so. Many original equipment engines may no longer be in production because of obsolesence or EPA regulations, so in some cases there may not be an exact replacement available. Our intention here is to show that other customers have utilized these in the equipment shown, but may have had to make some modifications to do so. If we know of any required changes, we will list those, however, some adapting during installation should be expected.
