Benefits of Landforming

• Higher Yields, Quality and Profit through
• Minimised water logging
• Improve infiltration uniformity
• Sooner trafficability
• Improved crop establishment
• Improved uniformity of crop maturity
• Reduced weed problems

8
OptiSurface Landforming
provides all of the benefits of traditional
laser landforming only

• MUCH BETTER!!

• Much cheaper (up to 80)
• Much less topsoil removal
• Much faster
