Closing Recommendation
Both machines do the same small-site jobs, so choose by your soil and your nearest service point. Take the Bobcat E37 Xtra when your ground is stiff, stony or part rock, because the extra power and stronger digging save you time on every trench. Take the JCB 37C HD when your work is normal soil, plot digging and pipeline jobs, because it uses less diesel, climbs slopes well and JCB service is easier to find in most districts. On a small machine, diesel and quick repair decide your profit far more than any single number in the table. So match the machine to your work: E37 Xtra for hard soil and heavier digging, 37C HD for lower running cost and easy service.
