1. Start with your hydraulic flow
Every Digga drive has a working flow range in litres per minute. Your machine's auxiliary flow needs to sit inside that range. You'll find it in your operator's manual, or your machine dealer can tell you.
2. Match the drive to your machine
Here's how four popular drives line up. Torque is Digga's theoretical figure at 240 Bar.
| Drive | Machine weight | Flow (L/min) | Torque @ 240 Bar | Largest auger, earth | From |
|---|---|---|---|---|---|
| PDX | 0.75 to 2t | 20 to 50 | 1,738 Nm | 600mm | $2,508 |
| PD3 | 2 to 5t | 45 to 75 | 3,577 Nm | 750mm | $2,563 |
| PD4 | 2 to 5t | 55 to 85 | 4,454 Nm | 900mm | $2,992 |
| PD6 | 5 to 10t | 70 to 115 | 5,649 Nm | 1,000mm | $3,850 |
Prices are RRP inc GST for the drive alone, without a hitch. Pick your hitch on the drive's page.
3. Check the auger size and ground
Bigger augers and harder ground need more torque. Each drive's page lists the largest auger it suits in earth, clay and rock, so check it against the holes you need to dig.
4. Choose your shaft
The drive's output shaft decides which augers fit: 65mm round on the PDX and PD3, 65mm round or 75mm square on the PD4, and 75mm square on the PD6. If you already own augers, tell us the hub and we'll match it.
