I installed this wheel motor on my Exmark Turf Tracer to replace the worn-out original, and it's been running great. Smooth operation, strong power, and no leaks. Mowing feels steady again, even on slopes. Good quality part and a perfect fit for the 1-603718 replacement.
I was worried about finding the right part, but the model number was a perfect fit. The installation was plug and play, just like the description says.
The tank feels solid and well-built. It holds a good amount of fuel (5 gallons), and I've noticed it works smoothly with my generator without any leaks or issues. The quality seems reliable for long-term use.
The parts in the kit feel solid and durable. After installing everything, my mower's transmission runs smoothly, with no leaks or issues. The quality of the components is top-notch, just like the original parts.
Even with basic tools, installation was smooth. Everything fit perfectly on my GX160 engine. The flywheel, starter, and fan cover lined up without any issues. Just follow a tutorial if you're unsure.
Clearly well-made and tested for accuracy-ignition is strong and consistent every time.
If your John Deere is shaking or making noise, this is an affordable and reliable fix.
