A Guide to Our Engine Replacement Kits

At Repower Pros, we provide high-quality, homeowner-friendly engine replacement kits for small engines. Our team has designed these kits to help Pennsylvania homeowners rebuild their lawn mowers at affordable prices with easy assembly. Our two main engine kits are the John Deere 425 Engine Replacement and the John Deere 445 Engine Replacement. Below is a guide to what’s included in each replacement kit, along with some assembly information. 

JD 425 Engine Replacement Kit 

Our JD 425 Engine Replacement Kit replaces the Kawasaki FD620D-S02 engine in John Deere 425 lawn tractors. They’re designed to easily drop right into your tractor, and also work great on 4-wheel steer models. If your engine has an auxiliary hydraulic pump between the engine and battery, it will require a different engine setup. Just inform our team of that before purchasing. 

What’s Included

We make our kit assemblies simple for homeowners. This kit includes new mounting brackets and hardware for the new engine, and a new muffler that’s designed to go out the side panel as the original muffler does. It also includes wiring that’s ready to plug into your mower’s original harness without needing to change anything. This engine features a mechanical governor, 4-stroke OGV, small engine, heavy-duty air cleaner, and a dipstick in the crankcase. The replacement kit comes with instructions, a 3-year consumer warranty, and a 2-year commercial warranty for your convenience.
