Abstract

A towable, residential sealcoating apparatus and related methods for applying sealcoat to a residential, asphalt driveway. The towable, residential sealcoating apparatus can include a towable implement having a mounting frame, a sealcoat reservoir, a distribution manifold and an applicator member. The sealcoat reservoir can supply sealcoat to the distribution manifold and applicator member at the direction of a supply valve accessible to an operator on a tow vehicle. The applicator member can be vertically adjustable from an upward transport disposition to a downward application disposition. The distribution manifold is operably removable so as to allow for cleaning of the distribution manifold following completion of the sealcoating process.

Claims

1. A residential sealcoat application system comprising:

a towing implement including a towing member; and

a tow-behind sealcoat apparatus having a towing receiver, a sealcoat reservoir, a repositionable wheel assembly, a distribution manifold, an applicator member and a driver-accessible delivery control;

wherein the towing member is operably interconnected with the towing receiver such that the towing implement can operably position the tow-behind sealcoat apparatus for application of sealcoat to an asphalt surface;

wherein the repositionable wheel assembly includes a driver accessible delivery lever for pivoting the repositionable wheel assembly so as to simultaneously position the sealcoat reservoir for gravity dispensing of seal coat while the applicator member is positioned against the asphalt surface; and

wherein operation of the driver accessible delivery control releases sealcoat from the sealcoat reservoir through the distribution manifold and onto the asphalt surface, wherein the applicator member spreads the sealcoat across the asphalt surface.

2. The residential sealcoat application system of claim 1, wherein the towing member and towing receiver define a ball hitch towing connection, a three-point hitch connection or a drawbar hitch connection.

3. The residential sealcoat application system of claim 1, wherein the applicator member comprises a squeegee or a brush.

4. The residential sealcoat application system of claim 1, wherein the repositionable wheel assembly comprises a pair of wheels operably joined to a mounting member with a pair of extension members such that rotation of the driver accessible delivery lever to an application position causes said extension members to reside in a generally parallel orientation to the towable frame wherein the applicator member is positioned against the asphalt surface and the sealcoat reservoir is tilted so as gravity feed any sealcoat to a reservoir outlet port.

5. The residential sealcoat application system of claim 4, wherein rotation of the driver accessible delivery lever to a non-application position causes said extension members to reside in a generally perpendicular orientation to the towable frame such that the applicator member is positioned above the asphalt surface.

6. The residential sealcoat application system of claim 1, wherein the towing implement is selected from a group comprising:

a lawn tractor and all-terrain vehicle.

7. The residential sealcoat application system of claim 1, wherein the distribution manifold is removably attached to the tow-behind sealcoat apparatus such that the distribution manifold is individually cleanable upon application of sealcoat to the asphalt surface.
