		When speaking about forestry in Finland it is good to remember that the growing season ranges between 120-180 days per year, the precipitation 550-700 mm per year, the soils are mostly rocky moraines, the target rotation period in southern Finland 70-90 years and 100-120 years in Lappland.
		The harvester is equipped with a crane having a reach of 10-12 m.
		Both the harvester and the forwarder are able to drive on a mat of branches and tops, which in addition to making the operation safe on soft ground, it is also an advantage from environment protection point of view.

	Journal of Forest Engineering at the University of New Brunswick
		The cost values of thinning specific harvesters, which are also capable of harvesting standard sized clear-cuttings, were referred from the publication of Ryynänen and Rönkkö [13], where the productivity and costs of different wheeled thinning harvesters were studied.
		If harvester work is carried out over a period of 11 months annually with a 1 work shift arrangement, operating costs per hour are the same as the thinning harvester with 1½-work shifts.
		The excavator-based harvester's cost-competitiveness comparison with the unit costs was made to the thinning harvesters, which could potentially be used for peatland thinnings but are also capable for use in clear cuttings.

	Timber West Journal May June 2002
		A number of forestry companies active in the Rocky Mountain States and American Northwest have traditionally used heli-logging as the only means of economically harvesting valuable timber situated on steep slopes and treacherous terrain.
		Timber stands will still need to be investigated for harvesting potential, trees will still need to be marked to avoid harvesting inferior wood and chain saw operators will still be needed at the landing to ensure that a thorough delimbing job has been done.
		Additionally, this method makes it possible for forestry companies to select harvest small- to medium-size timber in environmentally sensitive areas, as it has virtually no environmental impact because roads are required and the highest- grade trees be targeted.

	John Deere Forestry - 770D Wheeled Harvester
		The compact 770D harvester is designed for thinnings and harvesting of small-diameter wood.
		It’s compact size make it the most agile of the Deere harvesters, but it is built tough and well balanced for excellent stability.
		The 770D is equipped with the 745 harvester head, featuring an outstanding power-to-weight ratio to provide the flexibility needed in thinning operations.

	Development of a Flail Harvester for Small Diameter Brushand Coppiced Trees to Produce Energy/Chemical Feedstock
		The harvester was examined for 3 weeks in the southeastern United States in 2 m tall coppiced sweetgum, sycamore and water oak, in 4 m tall seedling sycamore, in 2.4 m tall pines, in 6 m tall pines and in seedling hardwood site with 4 to 9 m tall sweetgum.
		While the harvester was capable of mowing down the 4.5 m tall 10 to 12 cm diameter sycamore seedlings, the trees were not severed and captured by the shredder.
		Nevertheless, with improved cutterhead geometry, and the harvester operating at 2,100 rpm instead of 1,700 rpm (due to excessive hydraulic pressures at heat exchanger), it should be possible to routinely harvest 10 to 12 cm diameter sweetgum trees at 1.6 km/hr.

	A Review of Short-Rotation Forestry Harvesting in Europe
		Short rotation forestry is one of such sectors, and it ranks among "recovery of forest residues", "thinning to energy" or "upgrading traditional energy forestry".
		This paper concerns the harvesting of a certain type of short rotation energy forest, which happens to be the most common in Europe - and the one with the largest potential for expansion.
		Harvesting and chipping in two separate stages may be more sensible in a storage perspective, but it is still disproportionately expensive and therefore totally impractical.

		For PA ginseng harvested in previous harvest seasons, the name and address of the landowner is not required; however, all other portions of the form must be completed.
		The Harvester Certification form must be completed and signed by the harvester and given to the dealer at the time of transfer.

		Then the tree is laid on the ground and pulled through the harvester's felling head, where the branches are cut off by special knives.
		The length and diameter of the log are measured by the harvester's onboard computer, which then tells the machine just what lengths to cut the log into.
		Harvesters can fell 400 tonnes a week, about 15 times faster than a man with a chainsaw!

		JA Riggs of Fordyce Arkansas and Waratah Forestry Attachments coordinated a demonstration of a new Waratah HTH622 harvester /processor head on a Caterpiller 322 carrier.
		He wanted to try the larger harvester to compare it to the HTH620 harvester head that he currently owns, with the thought that he would add a second Waratah unit to their forestry lineup.
		The biggest advantage was that the larger head and the Cat 322 could handle the over sized 20 to 24 inch trees, and processing at the landing was no problem.

	The forest revenue system and government expenditure on forestry in Democratic Republic of Congo
		The tax administration for forestry in the Democratic Republic of Congo is made up of five services and public enterprises responsible for the collection of approximately ten taxes in relation to their areas of activity as the summary table presents them.
		In accordance with the texts of orders and various decrees regarding the setting of forestry taxes, public services and enterprises responsible for collection calculate taxes on the basis of volumes of wood felled in forests and declared by forestry harvesters.
		Central administration, decentralised bodies (provincial coordination, districts and territorial supervisors) have a means of follow-up and monitoring of forestry harvesting, but this process has not been in use for a long time, simply due to the lack of finance.

		There is even earlier evidence for conscious cultivation and seasonal harvest: grains of rye with domestic traits have been recovered from Epi-Palaeolithic (10,000+ BC) contexts at Abu Hureyra in Syria, but this appears to be a localised phenomenon resulting from cultivation of stands of wild rye, rather than a definitive step towards domestication.
		With the rapid rise of mechanization in the 20th century, especially in the form of the tractor, the demanding tasks of sowing, harvesting and threshing could be performed with a speed and on a scale barely imaginable before.
		Domestication of plants is done in order to increase yield, improve disease resistance and drought tolerance, ease harvest and to improve the taste and nutritional value and many other characteristics.

		The grapple which worked better in larger wood required only the shovel operator Of course it wasn't really a shovel as the shovel front was replaced with the heel boom, although occasionally someone just took the bucket off of a shovel and placed a grapple there.
		While many of the trucks shown here are of an International Harvester heritage, this isn't to imply that they are the only kind of trucks in the woods.
