Harvest Mass Management Scheme

The HMMS has been developed to assist the grain industry with the difficulties loading grain from a paddock.

The HMMS is not a concessional loading scheme. A Transport Operator is expected to aim for statutory mass limits when loading their vehicles off a paddock. However, given there are no weighing facilities on paddocks and there are known variations in grain densities, the HMMS allows for a margin of error during the loading process. 

With the assistance of the Grain Receiver, the loads can be adjusted accordingly for the next delivery, which eliminates serious overloads and works toward achieving fully compliant loading practices for the remainder of the harvest season.

The scheme commences each year between the first day of October and finishes on the last day of February. To join HMMS, operators are reminded to register with the relevant grain receiver.

HMMS Access Arrangements 2018-19

Changes have been made to continue allowing 'first and last' mile access on roads between the paddock and the nearest road approved for Restricted Access Vehicle (RAV) Network access. The changes ensure there are no adverse effects on road safety and Main Roads legal obligations are met.

For more information about the changes, please see the documents below:

The changes mean you must now apply to Main Roads if RAV access is required on roads between the paddock and the nearest road approved for RAV Network access under HMMS. To apply, a farmer or transport operator may submit a HMMS Road List form to advise us of the RAV combination and roads being used. The HMMS Road List must be endorsed by Main Roads before starting HMMS operations on these roads and be carried in the vehicle and produced to Main Roads, WA Police or the Grain Receiver upon request.

Main Roads will conduct a preliminary assessment of the nominated roads and provided the access is considered safe, endorse the HMMS Road List and return the list to the applicant. This endorsed HMMS Road List may be shared with other transport operators.

To ensure you receive your endorsed HMMS Road List in time for harvest, get your application in now. You need only apply for roads not on the RAV network.

HMMS Order and Business Rules

TheHarvest Mass Management Scheme Order 2018 must be carried in the vehicle and produced to Main Roads or WA Police upon request. Grain Receivers and transport operators are also reminded they must comply with all the requirements of theHMMS Business Rules.

HMMS Harvest Period Report

The HMMS 2016/17 Harvest Period Report outlines the key results from data submitted to Heavy Vehicle Services from the registered grain receivers during 1 September 2016 – 28 February 2017 harvest.

Scheme Registration - Grain Receivers

Grain receivers wishing to offer the HMMS to transport operators must be registered and approved to join the scheme.  To register, please complete the Grain Receiver registration form.  Participation 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.

Transport operators wishing to participate in the scheme must register with the grain receiver, not Main Roads.
