The effect of tyres and a rubber track at high axle loads on soil compaction, Part 1 Single axle-studies

摘要: One option for ground drive systems with large harvesting equipment is to use rubber-belted tracks; however, little known about the performance of these relative appropriately sized pneumatic tyres. The effect self-propelled wheels and a track high axle loads (9–24 t) on soil compaction were studied. Soil displacement density changes assessed by embedding talcum powder lines as tracer into during preparation. In addition, dry bulk penetrometer resistance measured. both 10.5 12 t compacts less than at 10.5 t load in weak uniform stratified soil. Towed implement 4.5 t caused similar 12 t. Tyre inflation pressure had significant influence parameters. To reduce larger overall diameter was found be more beneficial wider tyre. This emphasised importance contact its distribution respect changes. Total are important how distributed ground.
