Harvest Mass Management Scheme

HMMS provides a 10 per cent mass allowance for the transport of grain off a paddock to a registered grain receival operator. The scheme was developed in consultation with industry and grower representatives to cater for the loading difficulty caused by the natural variation of grain density and to provide flexibility in the movement of grains from paddock to receival facilities.

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


HMMS Order

Orders are published on the State Law Publisher (SLP) website and are available to download.  Operators are reminded they must carry the Order/s with them in the vehicle and must operate in accordance with the HMMS Business Rules.


 HMMS Bridge Crossing Permit

Under the new HMMS access arrangements, bridges on roads that are not already approved for the particular RAV combination must not be driven over, unless an HMMS Bridge Crossing Permit has been obtained. To apply for an HMMS Bridge Crossing Permit, please complete the HMMS Bridge Crossing application form and email it to hvsrouteassessments@mainroads.wa.gov.au.  The permit cost is $25 for the harvest period.

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.
