ETT has one of the largest ranges of mechanical tree spades in operation in Australia. The largest of these is capable of lifting trees with a height of 15 metres, trunk caliper of 350mm, and weighing up to 6 tonnes. This machinery is used mainly for off-site transplanting and relocation work. Larger trees can be relocated with the use of specially designed moving equipment and cranes. Trees of this size normally require root preparation over a prolonged period before lifting.

Many of the smaller tree spades are used for lifting the nursery trees out of the ground in preparation for shipment. Trees are shipped from the nursery on semi trailers equipped with cranes to assist with loading and unloading.
