If your Toro Groundmaster 4700D is having shutdown issues, this stop solenoid might be the fix you need. The part number 98-3817 is the exact replacement for the original equipment, and the 12V rating matches the machine's electrical system perfectly. Installation is straightforward if you're comfortable with basic mechanical work - just disconnect the battery, swap the old solenoid for this one, and reconnect everything. The quality feels solid, and it bolts right into place without any modification needed. I replaced mine after the mower wouldn't shut off properly, and the difference was immediate - clean, reliable shutdown every time I turned the key. The warranty is pretty good too - 6 months returnable and 1 year changeable, which gives you peace of mind. If you're dealing with a Groundmaster that won't stop running or is having intermittent shutdown problems, this solenoid is likely the culprit. For the price, it's much cheaper than taking it to a dealer, and it'll have your mower running properly again in no time.
