We have 4 different stump grinding machines to take care of stumps of any size in any location.  One of them is small enough to physically carry through a house to get those hard to reach stumps in enclosed back yards. We also have two loader mounted units for larger jobs.  Our forth unit is a self propelled unit that weighs 800 pound it provides enough power to take care of most stumps but does not leave ruts in yard like the larger units.
