Cutting blade:
Among the most critical elements of the Stump Machine is the cutting blade. It is also the most
subject to damage and wear. In the course of grinding stumps it not only makes contact with the
wood, but also encounters numerous assortments of abrasives and objects in the stump’s
environment, such as dirt, stones, and occasionally a large rock or buried scrap.
The loss of and wear of cutting teeth can significantly impair the efficiency and performance of the
Stump Machine. Therefore, it is important to make frequent observations of the condition of all
of the cutting teeth and replace or sharpen any damaged or worn blade sections.

Read all the following instructions before beginning to change cutting blade sections.
1. Clean all dirt from the cutting blade and mounting flanges.
2. Remove all bolts holding cutting blade, (Be
careful not to let a section drop when they
become loose).
3. Check each section for cracks. Replace blade
section if it is cracked.
4. When replacing cutting blade sections, make
sure blade section is placed in alignment with
blade rotation.
5. Refer to page of this Manual for proper blade
attachment.
Installing new blades:
Insert blade section between the blade mounting
flanges.
Slide bolt through one side of flange, and through
flange on other side. Attach lock washer and nut,
