“…Equation of draft prediction (ASABE Standards, 2009) indicated that by doubling the forward velocity, the draft requirement increased but was not doubled. Also many researchers confirmed this relationship between forward velocity and draft of primary implements (Upadhyaya et al, 1984;Crowell and Bowers, 1985;De Souza et al, 1994;Al-suhaibani et al, 2006;Sahu and Raheman, 2006).…”

“…The affecting properties and parameters of soil on draft force and required energy include the following: soil moisture content, bulk density, cone index and soil structure (Upadhyaya et al, 1984(Upadhyaya et al, , 1987. These parameters as the major influencing parameters on the draft force were analyzed in a clay soil (32% sand, 25.5% silt, and 42.5% clay).…”

A mobile instrumentation system was developed and mounted on an MF 285 tractor to measure the performance parameters of the tractor and attached implements. The system measures implement draft, fuel consumption, real forward velocity, tillage depth and engine speed. Other parameters such as wheel slippage, drawbar power and traction efficiency would be calculated by ASABE standard. Overall energy efficiency for the tractor-implement system was calculated, too. Three implements included of moldboard plow, disk plow and chisel plow at four forward velocities (1.5, 2.3, 3 and 4 km/h) in 23 cm depth and 1500 rpm engine speed was examined. Analysis of variance (ANOVA) of resulted data revealed that increase of forward velocity results in increase of implement draft, wheel slippage, drawbar power and overall energy efficiency but results in decrease of traction efficiency. Furthermore, fuel consumption decreased by increase of velocity from 1.5 km/h to 3 km/h but increased by increase of velocity from 3 km/h to 4 km/h. Moreover, it was observed that draft requirement for implements in tests ranged from 8.2 kN for the disk plow to 13 kN for the chisel plow and fuel consumption ranged from 10.72 L/ha for the chisel plow to 26.5 L/ha for the moldboard plow. The ranges in mentioned parameters indicate that energy saving can be readily done by selecting energy-efficient implements and by proper matching of the tractor size and operating parameters to the implements. ª 2015 The Authors.

Askari M., Komarizade M.H., Nikbakht A.M., Nobakht N., Teimourlou R.F., 2011. A novel three-point hitch dynamometer to measure the draft requirement of mounted implements. Res. Agr. Eng., 57: 128-136.An adjustable three-point hitch dynamometer with a draft capacity of 50 kN was developed to measure forces on the tractor and mounted implements. The design concept of the dynamometer was based on two linkage frames mounted between tractor links and the implement. The force sensing elements were comprised of a loadcell that was installed between the frames. The system provides variable width and height of the dynamometer links to satisfy a wide range of implement dimensions. All mounted tillage implements at categories II and III such as plows, cultivators and harrows were able to be tested by this dynamometer excluding mounted implements powered by power take-off (PTO). The dynamometer was calibrated and several field tests were conducted to measure the force required to pull a moldboard plow in a clay loam soil. The calibration showed a high degree of linearity between the draft requirements and the dynamometer outputs. Field tests showed that it was able to function effectively as intended without any mechanical problems.

ÖZETBu çalışmanın amacı, dipkazan ile çalışmada gereksinim duyulan traktör çeki gücünün azaltılmasına yönelik alternatif yöntemlerin etkinliğinin belirlenmesidir. Bu amaçla dipkazanın ön kısmına çalışma derinliği dipkazana göre daha az olan iki değişik tipte (bıçak keski ve disk keski) ek donanım takılarak farklı ilerleme hızlarında (yüksek, orta, düşük) çeki kuvveti, çeki gücü, yakıt tüketimi, iş başarısı, toprak penetrasyon direnci, toprak nem içeriği ve hacimsel kütle değerleri tespit edilmiştir. Deneme alanlarının her birinde iki dipkazan uygulaması (titreşimli ve titreşimsiz) uygulanmıştır. Çalışmada; çeki kuvveti, çeki gücü ve yakıt tüketimine ait en düşük değerler titreşimli konumunda normal dipkazan uygulamasında, en yüksek değerler ise sabit konumunda disk keski donanımlı dipkazan uygulamasında elde edilmiştir. İş başarısına ait en düşük değer sabit konumlu bıçak keski donanımlı dipkazan uygulamasında, en yüksek değer ise sabit konumlu disk keski donanımlı dipkazan uygulamasında elde edilmiştir. Titreşimli uygulamalarda iş başarısının artış gösterdiği belirlenmiştir. Hız artışına bağlı olarak iş başarısında bir artış olduğu görülmüştür. ABSTRACTThe study aims to determine the efficiency of alternative methods for reducing draught-power while working with subsoiler. For that reason, two different apparatus (blade and disc coulter) with working depth of less than subsoiler were attached to the front part of subsoiler and working characteristics, draught force, draught power, fuel consumption,
