<p>A tractor attachment to allow building surfaces to be treated with liquid and/or gas materials has a vertical framework wall (11) attached to a horizontal frame base (10) linked to the lift and pivot device (16) of the tractor (12). One of the differential drive shafts of the tractor is connected to the main drive unit (19) by a releasable link shaft (17). A pump (38) connected by a coupling to the drive system is mounted on the framework with a pipe (37) leading to a container at one end and to a bore with a hollow hand spray grip for wall washing at the other end.</p> |
