Abstract
The tractor trolley is suitable for on road transportation of agricultural
produce, livelihoods and implements. But for transportation within the territory of
agricultural fields and farmers place is not suitable, therefore this hydraulic operated
hay rake cum loader was developed for 500 kg carrying capacity. The device was
tested for loose (green / dry fodder) and bulk (grain / seed bags) loads on farm road
and tar road, respectively. The performance parameters considered for its evaluation
were loading/unloading efficiency, handling efficiency (handling time percentage
index, driving time percentage index and handling to driving time percentage index),
loading/unloading losses and spillage losses during transportation. The device can be
used for transporting loose and bulk loads on farm and tar roads. The field testing of
the developed device was found satisfactory under various operating conditions. The
subjective evaluation of the device was also carried out as per the Borg scale i.e. in
terms of Rating of Perceived Exertion (RPE), which indicated the operating
feasibility of the device. In the research conducted, the bulk load gave better results in
terms of all the parameters. The comparison between bulk load and loose load was
found highly significant for every performance parameter. The total cost of operation
of hydraulic operated hay rake cum loader was determined as ₹ 60.37/h. The payback
period and benefit-cost ratio was obtained as 2 years and 2.8, respectively
