In view of the current situation low degree mechanized harvesting rape shoots, combined with study material characteristics core components harvester were designed and analyzed, a shoots was manufactured. The front-end cutter cuts stalks while clamping conveying device transports steers flexibly to achieve damage orderly harvesting. forward speed machine, belt gap selected as test factors, rate...

predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. so, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

The selection of machines and the development operating systems are major challenge for reducing costs in harvesting forest transportation. This work aimed to carry out a technical analysis transport activities two different log lengths (6 7m). operational cycles Harvester, Forwarder combined road train vehicle mechanized harvest areas were evaluated. was performed through studies times movemen...

The use of short rotation, intensive culture (SRIC) practices in hardwoods to meet fiber supply needs is becoming increasingly widespread. Total plated area of short rotation hardwood fiber plantations is currently about 22,OfKI ha (McDonald and Stokes 1993). That figure should certainly to grow in response to public concerns over loss of natural hardwood stands. With many of the plantations cu...

Rainwater harvesting is effectively mandated in several urban areas of New Zealand. To understand the costs and benefits of rainwater harvesting from an end-user perspective, semistructured interviews were conducted with 14 homeowners in northern Auckland affected by these regulations. Residents report differences in four aspects of urban rainwater infrastructure - security of supply, water qua...
