Figure 3.10 Haulout and harvester fuel use (Sandell and Agnew 2002) Mallee System As a proven system robust enough to harvest mallee has not yet been developed the exact configuration of haulout vehicle is not known. Hence, the actual cost of the infield transport component is unknown. However, McCormack et al. (2009) in their model investigated the effect of haulout travel speed, transport distance and bin size on haulage costs. Figure 3.11 shows the influence of bin size and haulout speed upon the cost of infield transport, with costs ranging from $6 to $12 per green tonne. The cost is equally sensitive to both variables. Figure 3.12 shows the influence of infield transport distance upon cost, and compares this with the effect of pour rate. Estimates range from $5 to $12 per green tonne, and pour rate is much more influential upon the cost of infield transport than distance, because even at short transport distances, the harvesting system still requires two haulouts. Fuel, repairs and maintenance vary with the amount of work done per shift, but other costs are either effectively fixed on a daily or shift basis or fixed annual costs. Fuel use estimates for infield transport vary from 0.9 l/gt to 1.9 l/gt according to the assumptions about transport speed, distance and payload. These values are very sensitive to the details of operation, such as the proportion of time the haulouts spend under load at the rated engine speed, but it would be reasonable to assume that with longer transport distances, fuel use would be higher than the observed values in sugarcane. There is some potential for relatively good efficiency if the larger payloads lead to a better vehicle load to gross mass ratio with large mallee haulouts. 91

Conditional registration provides compulsory third party insurance in the event of a crash occurring on a road causing personal injury. Most agricultural vehicles are non-standard and therefore must be conditionally registered. The Queensland sugar industry has worked closely with the Department of Transport to ensure that infield haulage equipment are included under the conditional registration scheme. The Queensland Department of Transport provides guidelines for the conditional registration of three categories infield sugarcane transport equipment. These include: 92
