slightly forward this tends to put pressure on the rubber scraper 36 and it is believed that the plow blade 30 will not rise up on the mounting uprights 20 quite as easily as it will when the mounting uprights are perfectly upright in certain embodiments however it may be desirable to tilt the uprights forward about two and one half degrees from vertical this will allow the rubber scraper to flex to a higher degree and appears to have a shock dampening effect during snow removal also because the mounting uprights are tilted forward it has an added effect of keeping the blade down when it is in use in certain situations this is most desirable as a user may be able to obtain superior results when the blade rises somewhat less readily or when the scraper comes under a lower degree of force in this regard it is also noted that the rubber scraper needs to extend outward in front of the mold board it is believed that if the rubber scraper were straight up and down the blade would lift up too easily and the snow would squirt under the blade 30 and result in poor snow removal it is also noted that the rubber end caps will tend to bow outwardly even as great as 90 degrees to the direction of the movement of the plow this is desirable as it.
