I am new here. I need to plow/remove snow from my and my parent's mile long uphill gravel driveway. I am in Northcentral Pa. I inherited a Nissan Frontier (1998) with a plow from my father, who used to plow the driveway himself, but he has graciously allowed me to take it over now that he is 92...

My relatively new Boss ATV straight Blade turns side to side but won't go up and down. It has plenty fluid and you can hear the motor running when you try to raise or lower it. Any ideas anyone??
