A device for removing an object on a road surface includes a brush section which is provided at a vehicle body of a guide rail type vehicle traveling on the road surface extends obliquely downward toward the front side in an advancing direction of the vehicle body, and a lower end of the brush section being capable of coming into contact with the road surface; a brush support section that fixes the brush section; a fixing section fixed to the vehicle body; and a connecting section that is interposed between the brush support section and the fixing section to connect the brush support section to the fixing section.

A cantilevered debris plow comprising: a) A housing having a first end and a second end, wherein said first end is open for discharge of debris and said second end is closed for input of debris: b) A mounting plate configurable for attachment to a prime mover is attached to said housing, wherein said mounting plate is positioned between said first end and said second end of said housing and wherein the distance from said first end to said mounting plate is less than the distance from said second end to said mounting plate; and; c) A debris engager positioned in said housing to engage and convey debris from said first end to said second end of said housing for discharge.

A self-propelled snowthrower wherein, in one embodiment, drive members on each side of the snowthrower provide variable speed propulsion. A transmission that delivers power to the drive members may be adapted to de-clutch one of the two drive wheels when the ground speed of that wheel exceeds the driving speed of the transmission. In other embodiments, the snowthrower includes a rotor having a snow ejection surface forming a negative rake angle. Yet other embodiments include a chute rotation control mechanism that permits manual discharge chute rotation via one-handed input.
