Park your truck on a flat, level surface, or preferably against a grade, where the ground slopes upward, away from the rear of the truck to the area where the snow blower is located. For instance, if you have a driveway that slopes down from your house to a flat street, park the truck on the street with the back end facing the driveway.
Lower the truck's tailgate. Place the top end of the ramps on the truck's tailgate, with the other end of the ramps on the ground. Make sure the ramps are spaced apart the exact width of the snow blower's tread path.
Start the snow blower. Disable the snow blowing portion of the blower, if your snow blower offers that ability.
Align the snow blower with the ramps, so that the front of the snow blower is facing the ramps. Title the snow blower backward, so that the front of the machine can clear the ramps.
Engage the snow blower's forward drive and guide it up the ramps and into the truck. Shut the snow blower off once you're in the truck bed.
Pull the ramps up into the truck, so that you can remove the machine from the truck when you arrive at your destination.
