Yeomans (Bunyip) Slipper Imp with Shakaerator is a machine of great strength that successfully harnesses the amazing force of powered vibration to work the earth -r for grain crops, row crops, mulch forming, soil development and pasture improvement.

Conventionally shaped shanks and digging points compact the earth tighter immediately prior to contacting it.

The wombat slippers and shanks penetrate readily with a narrow point and flat angle, then splits and shatters the earth upwards. The vibrations from the Shakaerator greatly amplify this upwards split-and- shatter action. In shallow cultivation with the wide batswing slippers the vibrations flatten out horizontally and the fin dislodges the soil from the roots to greatly assist weed kill.

The draft reducing effect of the vibration from the Shakaerator is often clearly evidenced in deep cultivation when wheelslip occurs and the tractor stops if the Shakaerator is turned off.

The wombat slippers can be reversed (turned upside down). This feature overcomes the common problem of the undersurface of the digging point wearing to a convex shape and causing the point to ride up out of the ground. The thicker the leading tip the greater the problem. The inversion of the slipper produces a new cutting angle which readily penetrates the hardest of earths.

One of the primary objectives of the design of the wombats (digging points) had been to provide for a type of aeration of the soil and subsoil (the A and B horizon) that would most closely replicate the intimate capillary aeration that naturally occurs in deep fertile (living) soil.

It is not desirable to leave pockets of air in the soil. Plant roots will not readily cross an air gap. If it is more than 10mm the root will die back and send a branch root around the air space. Smaller air spaces can have a similar effect.

The Yeomans Slipper Imp has the right combination of shank and slipper designs, with the trembling shudder of powered vibration to produce mechanically a unique capillary type of aeration which is both intimate and complete. In many conditions there may be no apparent surface disturbance, yet the earth has been penetrated, split, fractured upwards, vibrated, aerated and returned almost to its original place.

Walking on the cultivated soil feels like a thick pile carpet.

The conversion of subsoil into deep fertile soil with the Slipper Imp is not a "once over" affair. It is a logical and progressive process, which continues for three consecutive years or more before the deep new soil assumes a strong degree of permanence. Correct management of the pasture plants and especially the control of the growth and declay cycle of the root systems is vital.

The Ryan Pasture Aerator

DESIGNED FOR PASTURE IMPROVEMENT ON
IRRIGATED OR HEAVY RAINFALL AREAS

Improve pasture growth by allowing roots and water to penetrate deeper into the subsoil.

THIS WILL:

• Give more available water in profile in times of severe heat stress and help lengthen the watering time pattern.
• Help prevent scald because less water lays on top.
• Slows down water rate and increases penetration on sloping banks.
• Gives a 4- to 6- inch profile for super phosphate to work on thus increasing its returns returns to the grasses.
• Allows more watar to be under the root system thus drawing the roots down.
• Tests show new roots deeper into the subsoil.
• deeper and longer roots means you have healthier grasses.
