Figure 7 shows average fuel consumptions, where a considerable difference is obvious between the disk harrow and the other two implements, how much more fuel is consumed for cultivation in the older way, which is a piece of information very much in favour of circular self-cleaning harrow and soil preparation machine which were far more economical.
The time sequence was: circular self-cleaning harrow, soil preparation machine and, last, the disk harrow. The data were processed according to the Tukey test (p [less than or equal to] 0,05).
In order to reach such one passage with the circular self-cleaning harrow, two passages with the soil preparation machine and three passages with the disk harrow were necessary.
It was anticipated that most time would be used for cultivation with disk harrow, almost one half less time is used for work with the soil preparation machine; the work is performed fastest with circular self-cleaning harrow (p [less than or equal to] 0,05).
Usually, offset disk harrows have larger disks, up to 20 to 24 inches in diameter, set on a spacing of 9 inches.
The angles in both types of disk harrows can be adjusted to regulate the cutting depth and mixing action.
However, the demand for rectangular balers, disk harrows
, forage harvesters and manure spreaders is predicted to decrease both years.
Rectangular balers, forage harvesters, grinder mixers, manure spreaders, mower conditioners, windrowers and swathers, field cultivators, chisel plows and disk harrows
show negative sales for 2000 ranging from 0.8 percent to 6.3 percent.
Tenders are invited for to obtain pricing and a contract for two (2) disk harrows
Congressman LaHood was given a tour of the facility, seeing firsthand what goes into making agricultural implements such as disk harrows
and crumblers that are used for soil management operations such as field tillage and cultivation.
A large Ukrainian manufacturer of agricultural machinery and part of Elvorti Group, Public joint-stock company Chervona Zirka (Kirovohrad) is projecting to ship a batch of disk harrows to E-Z Trail Inc.
The sides signed a contract, the cost of which is not being disclosed, to provide samples of all types of disk harrows to the United States.
