‘Enviro DD35’ Safety SAFETY - Machine Specific (Continued) Hazard Points on the Enviro DD35 (Continued) For guard locations on machine, refer Page 13. Transport The two wheels located at the sides of the machine are for the purpose of controlling sowing depth. These are also used to support the machine weight during transport (while linked to the tractor).
‘Enviro DD35’ Transport Transport Fig 1 Raise the drill into the transport position and hold at the full extent of the rams for a few seconds to allow cylinders to rephase/equalise. Important - To avoid machine damage due to drill lowering during transport, always close the hydraulic valve on the drawbar.
‘Enviro DD35’ Read Before Operation Components Referred to in the Pre-Calibration Setup and Calibration Process The following pages describe how to set the machine up for calibration, the calibration process and subsequent adjustments to obtain the desired seed and/or fertilizer output.
‘Enviro DD35’ Pre-Calibration Setup normal/fine toggle Start Empty boxes and clear old seed and fertilizer from high (idler in) metering unit. low (idler out) Is seed size between 4 and 10mm? Locate product in 'Normal' Locate product in 'Fine' seed seed table.
‘Enviro DD35’ Calibration Seed Calibration The calibration test should be done to confirm the settings of the required seed rate and is done with the drill stationary and level with the fan off. The metering units must be set prior to filling with seed.
‘Enviro DD35’ Calibration Hand Crank Turns for Seed Rate Calibration Turns Turns Machine Sowing for 1/40 for 1/10 Size Spacing(mm) Width (m) Hectare Hectare 27 Run 3.375 Weigh the seed collected during the test in kilograms. Caution: Scales must be accurate to 2 grams, as any error will be multiplied by either 10 or 40, giving inaccurate calibration results.
‘Enviro DD35’ Calibration Wheel Slip Deviations It is always possible with rubber tyred drills in extreme ground conditions to get wheel slip. Not normally a problem with cleated type tyres in good condition, but more so in the arable situation with the less agressive tread patterns.

‘Enviro DD35’ Phasing Cylinders Commisioning Phasing Cylinders 1. General (a) The cylinders will re-phase in both directions. Each piston is fitted with 2 poppet valves which open at the end of the stroke to allow oil to bypass the piston. The bypass of oil at the end of the stroke allows for initial bleeding of the system and re-phasing in operation.

Raise and lower the machine; all cylinders should move at the same time, any lag indicates that there is air in the system. Re-bleed the system if necessary.
