MODIFICATION OF MECHANICAL A TRANSPLANTER TO SUIT TOPPING SUGAR BEET
The main objectives of the present study is to construct suitable topper unit for topping sugar beet crops using the power unit of the prime mover of Yanmar ARP-8 Rice Transplanter to meet the demands of small and medium farmers in Egypt
Tests were conducted at the following topper forward speeds of 1.5, 2.0, and 2.5km/h, topping heights of 1.0, 2.0, and 3.0 (clearance between knife and feeler), and sugar beet moisture content 35.0, 42.0, and 50.0 % were used.
The results showed that by increasing the forward speed from (1.5 to 2.5 Km/h) tends to increase the over topping from (2.90 to 3.22 %), under topping (2.82 to 4.02 %), untopped (3.71 to 4.26 %), effective filed capacity (0.26 to 0.75 fed/h) slip ratio ( 4.0 to 7.9%) and power requirements (2.40 to 6.48 kW), and decreasing the correct topped beet from ( 92.00 to 90.39 %), topping efficiency from ( 96.29 to 95.74 %) and cost for topping operation ( 79.4 to 27.5 LE/fed) .The results also showed that by increasing the topping heights (clearance between knife and feeler) from (1 to 3 cm) leads to increase the topping efficiency (96.29 to 97.23 %), overtopping ( 2.50 to 3.22%) and decrease the under topping (4.02 to 2.60 %), and untopped beet (3.71 to 2.77 %).
