Stump planers work  on your auger drive and slice out the stump from the top down. 

Stump grinders chew up the stumps. 

Stump Buckets:

The smooth edge Utility Bucket is good for moving small trees, ditching / contouring, etc. 

The toothed HD Utility Bucket is good for smaller stumps and trees, ditching / contouring, etc. 

The Extreme Duty Stump Bucket is great for removing large stumps from the ground. Use the serrated edges like a saw on those long roots.
