5-1 Preventative Maintenance Schedule
The mechanical design of the GH Hopper is very simple and very little maintenance is

mixer agitator. The checklist below contains a list of items which should be inspected and/or
replaced to keep your GH Hopper operating at peak efficiency. Perform each inspection at
the regular intervals listed below.
