On the New Zealand Tractor stand at Waimumu was the Sumo Grassland Subsoiler (GLS) ideal for local conditions with the larger model needing at least 135hp to operate efficiently.
Grant Reith, managing director of New Zealand Tractors which imports Sumo cultivation products, is the first to admit that while well known in the UK and synonymous with size and quality the brand is only now getting recognised in New Zealand for the same reasons.
"They make a range of products generally suited to the larger farmer and contractor."
He reports the contracting scene here is changing as operators see the economy of scale with larger tractors and machines.
"As an indication last season I had 10 customers with 500hp tractors and within 12 months I will have 20 customers with these large machines."
In one pass the GLS will alleviate structural compaction in the root zone, consolidate and aerate the surface, removing and scattering any dead vegetation and surface debris. It leaves a soil environment conducive to plant and grass growth, better able to stand the rigours of wet or dry weather.
The method is firstly a row of serrated edged discs on individually suspended arms cut through the surface. The depth they work is altered by a one bolt system. They are followed directly behind by the legs which can easily enter the pre-cut soil. The legs have auto re-set as standard and have a two piece point on the shoe which lifts and fractures the soil. There working depth can be adjusted between 100-350 mm.
Then the full width packer with a diameter of 508mm rolls the land back down again. It has shark finned attachments which ensure surface soil aeration and act as a positive drive to the packer. Finally at the rear is a scarifying harrow which disturbs and removes any dead vegetation and scatters any surface debris as well as covering any seeds broadcast in the process.
The depth the harrow works can be adjusted or lifted completely out of work when not needed.
A seeder can be attached to the machine which will broadcast seeds in bands behind each leg.
