Field tractive performance of three popular two wheel drive tractors in iran

Evaluation and comparison of traction performance of two common tractors in iran

ارزیابی و مقایسه بازده کششی تراکتورهای مسی فرگوسن (MF 285) و یونیورسال (U650)دراجرای شخم باگاوآهن برگردان دار

In this study tractive efficiency (TE) of MF285 and U650 tractors during moldboard plowing were evaluated and compared. Field experiments were conducted at the Experimental Station, College of Agriculture, Shiraz University, using a randomized complete block design with a 3*3 factorial. The soil was sandy clay loam with an average moisture content of 18% b.d. from zero to 30 cm depth. Test trea...

تأثیر بار محوری و بار کششی بر بازده زمین گیرایی و مصرف سوخت دو تراکتور سنگین در اجرای شخم با گاوآهن برگردان دار چهار خیش نیمه سوار

Tractive efficiency and fuel consumption of Massey Ferguson (MF399) and John Deere (JD 4230) tractors during plowing with moldboard plow were evaluated and compared. The tests were conducted at the Experimental Station, College of Agriculture, Shiraz University, in a field with sandy clay soil at average moisture content of 18% d. b. from zero to 30 cm depth. A randomized complete block design ...

Improvement of wheel skidder tractive performance by tire inflation pressure and tire chains

Nacrtak The motion resistance ratio, gross traction ratio and net traction ratio of a wheel cable skidder were determined and mathematical models derived for three tire inflation pressure values with or without tire chains on forest road in mountainous conditions. The motion resistance ratio increases with the increase of tire inflation pressure. On the contrary, the gross traction ratio increa...
