Field Performance of Rubber Belted and MFWD Tractors in Southern Alberta Soils 972730

Traction performance and fuel efficiency tests were run at the Alberta Farm Machinery Research Centre to compare two different rubber belt tractors with two similar radial tire equipped mechanical front wheel drive tractors. Three different test methods were used in both tilled and untilled clay loam soil. The optimized systems showed only small differences in overall performance and efficiency in good traction conditions and at vehicle traction ratios of 0.4 to 0.5. This was also where both types of vehicle showed their best power delivery performance. Belted tractors showed their greatest benefit when operated at VTRs of 0.6 or higher or in soft or loose soil conditions.
