How to Use
Getting started with the Tool Tuff Model 400 is straightforward, but a little know-how goes a long way. Here’s how to make the most of it:

  1. Attach to Your Tractor: Hook up the 3-point hitch to your tractor’s lift arms and secure it with the included pins. Double-check everything’s tight.
  2. Connect the PTO: Attach the PTO driveline to your tractor’s PTO shaft, and don’t forget to ensure the safety shields are in place—you don’t want any surprises.
  3. Choose Your Auger: Select the right size for your job (6", 9", or 12") and bolt it onto the digger. Make sure it’s secure; you don’t want it slipping mid-dig.
  4. Position for Digging: Lower the digger to the ground and line it up where you want the hole. Take a moment to make sure it’s level and steady.
  5. Start Digging: Engage the PTO to get the auger spinning, then slowly lower the digger into the ground. Let the tool do the work—don’t force it.
  6. Safety Reminders: Always wear protective gear, keep bystanders clear, and follow the manufacturer’s safety guidelines. A little caution goes a long way.
Maintenance Tips
To keep your Tool Tuff Model 400 digging strong for years, a little TLC goes a long way. Here’s how to keep it in top shape:

  • Check Fasteners Regularly: Give all bolts and pins a good tighten after every use. Loose parts can lead to bigger problems down the line.
  • Inspect the PTO and Shields: Look for wear or damage on the driveline and safety shields. Replace anything that looks sketchy—safety first!
  • Maintain the Augers: Keep those edges sharp or swap them out when they’re worn. Dull augers make for slow, frustrating digs.
  • Lubricate Moving Parts: Follow the manufacturer’s recommendations for greasing gears and joints. A well-lubed machine is a happy machine.
  • Store It Right: Keep it dry and covered when not in use. Moisture is the enemy of metal, so don’t let it sit out in the rain.

With these simple steps, your digger will be ready for action whenever you need it.
Things to Consider
Before you pull the trigger on buying the Tool Tuff Model 400, here are a few things to keep in mind:

  • Tractor Compatibility: Double-check that your tractor is compact, sub-compact, or Cat 0. This digger won’t play nice with larger models.
  • Ground Conditions: Think about where you’ll be digging. Hard, rocky soil might need more power or a larger auger, while softer ground will be easier on both you and your tractor.
  • Hole Size Needs: Know how deep and wide your holes need to be. The auger sizes (6", 9", 12") give you options, but pick the right one for your project.
  • Comfort with Assembly: Be ready to spend some time putting it together and attaching it to your tractor. If you’re not handy, you might want a buddy to help out.

Also, don’t forget to read the manual—those safety guidelines aren’t just there for show. A little prep goes a long way toward avoiding headaches later.
