摘要:
An asphalt rake includes a handle, a rake head, and a valve. The handle includes a cavity to hold a fluid, such as a release agent. The rake head has a passage in fluid communication with the outlet of the handle. The passage is in fluid connection with a support member outlet that is configured to be positioned apart from the crossbar by a gap. The valve controls fluid flowing from the cavity in the handle to the rake head. Fluid applied to tines of the rake head can prevent asphalt buildup on the rake head, which provides convenience and improves efficiency when smoothing or otherwise working with asphalt.
