Flat-Bed Trailers When loading a flat-bed trailer, remove the self-storing ramp and place it securely in the groove or channel on the side for which you will load the snowmobile. If the trailer has fold down ramps, remove the security pin and fold the ramp down so it is in place for loading. Double check the ramp to be sure it is secure, drive the snowmobile at a moderate speed up the ramp, letting off the throttle as the skis reach the trailer bed at the top of the ramp. Slowly drive the snowmobile forward until it is over the location where it will be secured and set the brake. The flat-bed trailer will either come equipped with a rod or a bar to secure the snowmobile to the trailer. A rod will go across the skis and is held in place at the outside end by a snap pin. A bar will go across the skis and be screwed into the trailer’s deck at a preset receptacle at the center of the snowmobile trailer bed. Also secure the rear of the snowmobile with a ratchet-type tie-down strap. Move the self-storing ramp to the other side of the trailer and repeat the loading process if there is more than one snowmobile. When you have finished loading the snowmobiles, replace the self-storing or fold up ramps and secure with the safety pin(s). When unloading a flat-bed trailer, be certain the tow vehicle is turned at an angle away from the ramp to allow room for the ramp and snowmobile to exit safely. Place the self-storing ramp at the front of the trailer, or fold down the folding ramp. Remove the tie-downs, release the snowmobile’s brake, and drive the machine slowly off the trailer and down the ramp, using caution to stay clear of the tow vehicle. Replace the ramp, secure it, and store all tie-downs in a safe place.
