Abstract/ Executive Summary:

A CLAAS CROP TIGER 30 Wheel model combine harvester was tested to evaluate its field performance and to determine the harvested grain quality and different losses. Harvester was tested two different speeds 3.4 km/hr and 4.6 km/hr. Width of cutting were 2.65m and 2.60m at the speed of 3.4 km/hr and 4.6 km/hr respectively. At the lower speed of 3.4 effective field capacity, field efficiency, fuel consumption, harvesting efficiency and total loss of rice were 0.72 ha/hr, 80 percentage, 7.50 lit/hr, 99.90 percentage, and 3.38 percentage respectively and at the higher speed of 4.6 km/hr the above values were changed to 0.84 ha/hr,70 percentage, 7.75 lit/hr, 99. 63 percentage, and 4.62 percentage respectively.

Objectives:

1.To evaluate the field performance of CLAAS CROP TIGER 30 Wheel model combine harvester and

2.To determine the harvested grain quality and different losses.

Methodology:

The CLAAS combine harvester is certified with the latest international quality standards of ISO 9001:2008 and ISO 14001:2004. The unique Tangential Axial Flow (TAF) technology for threshing and separating syplant is especially designed to equip CLAAS combine harvester with multi cropping ability. High centrifugal forces along the threshing and separating rotor gently act on each and every rice and thus CLAAS combine harvester not only harvest crops like wheat and rice but also delicate crops like soybean, gram, mustard, mung and basmati. This technology also results in excellent rice quality, negligible breakage and minimum losses. The technical specifications of the CLAAS combine harvester.Methods Three rice fields were used for combine harvester testing under Dinajpur district. Row planting method was used for harvesting having same crop condition. Rice variety was BR-29. Table 2 showed the rice field condition. The total quantity of the rice discharged from the unloading auger in the length of test run was collected and measured to calculate the flow volume. From these rices, sample rices for quality check were also collected. The rice which dropped due to the vibration of the machines head in the test location after cutting were picked up from the three sampling area within the length of test run and converted in term of dropped rice in the area of test run. The size of each sampling area was 1 m long and across the machine working width. All the residues discharged from the chaff and straw outlets in the test area were placed on a plastic sheet.

Achievement/Findings:

The general performance of the CLAAS combine harvester was very satisfactory. It could harvest very well even is small field and lodging rice field condition. Total grain loss is not high, loss can be decreased by operator training operation. Any way CLAAS Combine harvester may be a solution of labor shortage problem during peak season of harvesting'
