Motor Grader Roadeo Course Details

1. Ditching (350 points)
   The objective is to knock balls off the bases while leaving the bricks on either side of the ball and base still standing. The operator lowers blade into ditching position to hit balls off of stand. Deductions will result if metal collars are touched.
2. Ice Curb Pull (350 points)
   The objective of this obstacle is to test the operator’s ability to negotiate a tight left turn. The operator will be required to come to a complete stop before the stop line. After stopping, the operator must negotiate a tight left turn while striking only the red grade block on the radius turn. This task must be accomplished in a continuous motion operation. Operator must knock off the red block and any block above the red target block. Blocks knocked off below the red block will not receive a score.
3. Offset Alley (350 points)
   The objective of this obstacle is to simulate maneuvering a Motor Grader through multiple objects while removing snow. The operator will be required to maneuver the Motor Grader through the three alleys and will be required to hit the softballs off the t-stands placed between each alley by utilizing mold board, wheel lean and the articulation portion of the grader. Points will not be scored if blade touches t-stand. Points will be deducted for hitting any other portion of the alleys.
4. Cul-de-Sac (350 points)
   The operator uses all steering functions to strike the cow bell cones in a left hand turn. Deductions will result if the blade touches any part of the stand.
5. Serpentine Course (450 points):
   The objective of this obstacle is to test the operator’s ability to maneuver the Motor Grader through an offset serpentine in forward. The obstacle simulates objects in the roadway. The operator will be required to maneuver the grader through the offset cones without touching any cones.
6. Ball in Chute (350 points)
   The objective is to pick up the bowling ball with the tow of the moldboard, carry it a short distance, and place it into a chute with the heel on the opposite side of the motor grader.
7. Alley Dock (250 points)
   The alley dock tests the operator’s ability to back the grader into a confined space. The operator must back into the space without hitting the sides and must stop as close to the back of the barricade as possible without hitting it. In addition to not hitting any of the barricades in the alley dock, it is the operator’s responsibility to sound the horn. When the horn sounds, the judge will measure the distance from the rear hitch to the back of the barricade. This will also signal the time keeper that the operator has completed the course. If the operator forgets to sound the horn, the judge will not be able to accurately measure the distance in the alley dock and the course time will continue. After the judge completes his/her measurement, the operator must drive forward to the start time.
