SnowDogg Part # 16151200 - HT300, HV600 Motor is your SnowDogg plow motor if you have an HT300 or HV600 HPU hydraulic system. This motor is an OEM SnowDogg motor which was manufactured by SnowDogg. You'll probably find aftermarket motors out there that are cheaper, however they are not warrantied by SnowDogg and they will not last half as long as a genuine SnowDogg plow motor. You'll find the motor connected to your HPU unit and the hydraulic manifold assembly on the plow side of your SnowDogg setup.
