Abstract
The performance evaluation of a tractor-drawn 9-tyne cultivator aimed
to assess its operational efficiency at different engine speeds for field crop.
The study took place at Aditya University Agricultural Field Laboratory in
Surampalem. Researchers used a 45 HP tractor operated at three engine speeds:
1500, 2000, and 2500 rpm. Key performance parameters included forward speed,
theoretical field capacity (TFC), actual field capacity (AFC), field
efficiency, and fuel consumption. The results showed that forward speed
increased with engine speed, ranging from 3.4 km/h at 1500 rpm to 5.4 km/h at
2500 rpm. Similarly, TFC rose from 0.612 to 0.999 ha/h, while AFC improved from
0.54 to 0.88 ha/h. Field efficiency remained quite stable across all
treatments, averaging about 88%. This indicates minimal time losses due to
turning and overlap. Fuel consumption increased from 1.20 L/h at 1500 rpm to
2.00 L/h at 2500 rpm. This showed a strong positive linear relationship with
engine speed, with an R² value of approximately 0.9998. Regression and ANOVA
analyses confirmed significant relationships between engine speed and both AFC
and fuel consumption at the 1% probability level. The findings suggest that
using the cultivator at a moderate engine speed, around 2000 rpm, offers a good
balance between field productivity and fuel efficiency. The study confirms that
the 9-tyne cultivator is suitable for small and medium farms that need
efficient and timely tillage operations.
