    I recently bought a case 850 dozer with 6 way blade will raise and lower and angle fine will not tilt I think someone has the lines routed wrong from the 3 that come out of the front of the dozer . If you push the handle left or right it try's but acks like it's dead head thanks 20191006_101634.jpg 20191006_101641.jpg
