WE HAVE THE LARGEST RANGE OF MECHANICAL TREE SPADES IN
OPERATION IN AUSTRALIA

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. These are rear mounted on tractors, which dig, lift and replace the trees in a new position or container ready for dispatch. The hydraulic blades of the tree spade surround the tree severing the roots as they dig into the ground. The tree with cone shaped root ball completely surrounded by the mechanical spade is then extracted out of the ground. The different sized tree spades lift trees with root ball diameters of 450mm, 600mm, 750mm, 825mm, 1120mm, 1625mm and 2250mm.

Trees are shipped from the nursery on semi trailers equipped with cranes to assist with loading and unloading. ETT also provides an offsite transplanting service, we’ve relocated trees in forests, plantations, city and town re-developments, domestic landscaping projects, as well as relocating orchards, groves and vineyards.
