Accurate measurement of slip rate (SR) in agricultural tractors, particularly Iraq, is essential for optimizing tractive efficiency, fuel economy, and field efficiency. Presently, tractors Iraq lack sensors SR detection, posing a challenge. This research addresses the issue by introducing wireless technology, novel digital slippage system (NDSS), designed to precisely measure rear wheels. The NDSS was tested across diverse conditions, involving six soil textures various kinds tillage equipment (A-TE). Different practices, including conservational (CT) with chisel plough, traditional (TT) moldboard plough disc minimum (MT) using harrowing spring tooth harrowing, were examined. Results from compared techniques, demonstrating cost effectiveness overall performance. Silty loam exhibited higher values, while silty clay showed lower values. varied significantly textures, more cohesive soils leading reduced percentages. Additionally, methods had marked influence on use CT resulted values 18.35% TT MT systems, which recorded 13.69% 6.03%, respectively. measurements also found be affected draft force during loading A-TE, emphasizing role operational conditions tractor performance, especially challenging environments. Comparison between techniques revealed that offered high accuracy, flexibility, configurability, consistent demonstrated superior precision, making it an effective tool assessing tractors.

In order to explore the influence of wheel surface structure on trafficability planetary rovers soft ground, three kinds wheels with different rigid structures were selected for research. The basic performance parameters simulated soil are measured and tested law wheel’s sinkage, slip rate traction coefficient. results show that grouser increases sinkage wheel. tread reduces wheel, but it also at a higher rate. Considering complex working conditions rover six-wheeled three-rocker-arm is used carry out passability tests in terrains: obstacle crossing, climbing. grousers can cause disturbance damage have significant passing advantages. There may be phenomenon when crossing obstacle, does not affect passing. completely closed will accumulation between grouser, affecting ability escape sinkage. This study provides reference design from perspective performance.
