Harvest Mass Management Scheme (HMMS)
This scheme was developed to assist the grain industry with the difficulties experienced loading grain from a paddock, and it is not a concessional loading scheme.
The Harvest Mass Management Scheme commences each year between the first day of October and finishes on the last day of February.
Participation in the HMMS is voluntary, however, non-participating grain receiver operations will not be able to offer the HMMS allowances to transport operators delivering grain to their receival depots.
Grain receivers wishing to offer HMMS must be registered and approved to join the scheme using the Grain Receiver Registration Form.
Grain Receivers and transport operators must comply with the HMMS Business Rules.
To comply with HMMS requirements the Harvest Mass Management Scheme Order 2019, must be carried in the heavy vehicle and produced to Main Roads or WA Police upon request.
