A Small tractor operated BBF maker was
developed and evaluated for its performance in the
Department of Farm power and machinery, Dr.PDKV,
Akola. Techno-economic feasibility of small Tractor
operated broad bed furrow maker was carried out during
the study. Implement was tested in laboratory and in the
field .The main components of the implement were main
frame, hitch assembly, forming board, adjustment lever,
cutting blade, hitch pair. The working width was 120 cm
depth of operation was 25 cm. The average draft
requirement of the implement was 164.4 kgf for implement
at an average speed of 2.22 km/h for the range of 18.5 hp
tractor. The average effective field capacity, theoretical
field capacity and field efficiency of implement was found
to be 0.30 ha/h, 0.40 ha/h and 76.97 per cent respectively.
The average collection efficiency was found to be 81.47 per
cent and wear per cent was found to be 0.041%/h. The
operational cost for broad bed making was Rs. 258.94/h
and Rs 914.30/ha. The overall performance of the small
tractor operated broad bed maker during the operation of
was found to be satisfactory.
