“…This meant that approximately 49.75, 27.47, and 46.56% of the engine power was consumed as PTO power in the conventional, APS ECO, and APS power modes, respectively. Hensh et al [27] reported that the PTO power consumption was in the range of 20.11% to 71.77% for a depth increase of 50 mm to 150 mm. Upadhyay and Raheman [28] also stated that the PTO power consumption was in the range of 26.90% to 63.74% for an average working depth of 120 mm.…”

The objective of this study was to estimate power delivery efficiency and fuel consumption based on engine modes. In this study, a 95 kW power-shift tractor was used to analyze power delivery and estimate fuel consumption during rotary tillage. Rotary tillage was conducted in a field experiment with the conventional, APS (auto power shift) power, and APS ECO engine modes. To analyze the field conditions, the soil hardness and soil water content were measured, and soil samples were collected from the experimental site to analyze the soil texture by using the USDA soil texture triangle. Finally, an efficient and suitable engine mode was selected for rotary tillage based on the working load. It was observed that the power delivery and tractive efficiencies when using the APS power mode were the highest among other engine modes, accounting for around 89.23 and 73.45%, respectively. However, the fuel consumption when using the APS power mode was approximately 23.02 L/h, which was also comparatively higher than that of the other engine modes. Additionally, the tractive efficiencies of each engine mode were compared using the Brixius prediction model. The statistical analysis of the predicted tractive efficiencies and those in the tests showed that there were no significant differences among the engine modes; this indicates that the APS controller could perform with high accuracy. In the conventional mode, the power delivery, tractive efficiency, and fuel consumption were approximately 66.48%, 55.89%, and 17.04 L/h, respectively, which were comparatively low. However, the slip ratio in the conventional mode was 18.80%, which was higher than that in the APS power and APS ECO modes. On the other hand, PDE, TE, and fuel consumption when using APS ECO were around 77.57%, 58.44%, and 19.39 L/h, respectively, which were higher than those of the conventional mode, but lower than those of the APS power mode. Furthermore, the comparative analysis showed that the working loads in the APS ECO mode were located in the ungoverned region and were very close to the engine’s maximum torque, which could allow sudden and unwanted engine turn-off due to the fluctuations in working loads, which is to be avoided. The fuel consumption was also comparatively low. However, the working loads in the conventional and APS power modes were located in the governed region, which was outside the engine’s operating range. Therefore, we recommend that users operate tractors in the APS ECO engine mode for rotary tillage, considering fuel economics and high working loads.

A rotating shaft torque sensor so-called a torque transducer for power data determination of rotary farm implements was developed, fabricated, and calibrated. It built according to the working theory of the commercial power take-off (PTO) torque meter model of Lebow Model 1228-20k, Eaton Advanced Electronics, Troy, Michigan, USA using local materials. For a typical torque measuring design, resistance type strain gages were glued to a spline shaft surface similar to a PTO shaft and integrated into a Wheatstone bridge circuitry. A slip ring was used to interface the bridge circuitry on either side of the transducer to a data logger named Daytronic data PAC model 10k4. For a torque range of 0 to 5 kN.m, the fabricated torque transducer has been constructed. A 60 teeth gear was installed on the torque transducer to measure the rotational velocity. Laboratory static and dynamic calibration tests were conducted. The dynamic tests were accomplished during the full load varying speed tests using a hydraulic PTO dynamometer type AW NEB 400. In both dynamic and static calibration tests, the fabricated torque transducer confirmed high accuracy measurement with linear relationship addressed by determination coefficient (R2) in the range of 0.992 to 0.9994. The fabricated PTO torque transducer is less expensive considering the typical commercially available PTO torque transducer. For acquiring PTO torque data during field operations, particularly when using a rotary plow or similar implements, the fabricated PTO torque transducer can be installed on the tractor's PTO shaft easily.

Background and Objective: Most single-sided mouldboard ploughs have challenges of needless empty turns and reduced ploughing efficiency. This requires a more efficient plough with reduced empty turns. The study aimed to develop a ride-on 2-bottom MB plough with seating and hydraulic lift jack attachments. Materials and Methods: The equipment consists of two major parts: The prime mover (power-tiller) and the accompanying implements, which include, the implement carrier, operator seat, the hydraulic jack pump and two mould board plough units. The machine was developed and fabricated based on standard engineering principles for part-sizing and materials selection. The machine was tested and the performance was evaluated using descriptive statistics. Results: The developed machine is dynamically stable and ergonomically suitable for operator comfort and manoeuvrability during field operation. The measured average cutting depth, width and speed parameters are 14.84, 24.56 cm and 3.48 km hG 1 , respectively. The evaluated average field efficiency and theoretical field capacity are 88.23% and 0.096 ha hrG 1 , respectively. The equipment is appropriate for small-scale farmers. Conclusion: A ride-on plough was successfully designed, constructed and tested for functionality and field performance. The cost implications showed that the machine is economically affordable for low-income farmers who could purchase the power tiller through joint ownership ventures.
