Dorset firm Evans and Pearce has redesigned its Logic slug-pelleter to improve spreading accuracy out to 24m. The redesign follows on from our multi-test two years ago that revealed the wildly inconsistent throws of most machines.

The company (which makes Logic’s broadcaster) has switched to a double-disc arrangement that sandwiches the three spreading vanes to reduce air turbulence and minimise disruption to the spread of material. Using aluminium rather than stainless steel also trims weight and torque loading on the motor drive, which should help in maintaining a steady disc speed.

During our test we found that granules worked their way between the hopper shutters, which sometimes caused leakage. To try to prevent this, the main aperture slider has been sandwiched between two plates so that it generates a shearing action as it closes, making for clean cut-offs at the headland.

The actuator that performs this task has also been changed. Previously an adapted car aerial motor that could generate 10Nm of torque was used, but that has now been swapped for a much beefier unit that will deliver 120Nm. The broadcaster is also now wired direct to the battery of the mounting machine, so there is much less likelihood of voltage drops and motor speed is unaffected by lead length.
