Abstract
Abstract A method for preparing a soil surface for grass growing wherein soil is continuously scraped from the surface in advance of a travelling reel carrying mesh sheet. The reel is continuously unwound during travel and the mesh sheet is laid on the scraped surface while the scraped soil is continuously conveyed to the rear of the reel and deposited on the laid mesh sheet. Apparatus for carrying out the method is also disclosed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
85 words
A method of embedding a reticulate mesh or net surface within a scraped soil surface for grass growing comprising continuously unwinding a reticulate mesh or net sheet onto the scraped surface from a travelling reel while continuously scraping soil from the surface in advance of the reel, conveying said scraped soil to the rear of the reel, mixing said scraped soil with seed, holding said sheet in contact with the scraped soil surface and continuously depositing said seeded scraped soil onto the already laid sheet.
Claim 2
Independent Claim
85 words
A method of embedding a reticulate mesh or net surface within a scraped soil surface for grass growing comprising continuously unwinding a reticulate mesh or net sheet onto the scraped surface from a travelling reel while continuously scraping soil from the surface in advance of the reel, conveying said scraped soil to the rear of the reel, mixing said scraped soil with seed, holding said sheet in contact with the scraped soil surface and continuously depositing said seeded scraped soil onto the already laid sheet.
Claim 3
Dependent Claim
28 words
A method as claimed in claim 1 including depositing grass seeds onto said surface before soil is scraped therefrom whereby said seeds become mixed with the scraped soil.
Claim 4
Dependent Claim
26 words
A method as claimed in claim 1 including depositing grass seeds into the scraped soil before the scraped soil is deposited onto the already laid sheet.
Claim 5
Dependent Claim
125 words
A machine for preparing a soil surface for grass growing comprising a structure mounted on wheels for travel along the soil surface, a reel mounted on the structure of reticulate mesh or net sheet whereby travel of the structure along the soil surface causes the sheet when underneath the wheels to be continuously withdrawn from the reel and laid on the surface, scraper means on the structure forwardly of the reel mounting means for continuously scraping soil from the surface in advance of the reel during travel of the structure, conveyor means on the structure for conveying soil from the scraper rearwardly to continuously deposit said soil on the already laid sheet to the rear of the reel and seeding means mounted on said structure.
