Closing Recommendation
Both are capable AJAX self loading mixers, so pick by your daily concrete need and your site ground. Choose the AJAX ARGO 2500 for house building, small drains and tight plots, where a smaller drum is enough and the fuel bill stays low. Choose the AJAX ARGO 3000 when you pour big slabs, work far from a ready-mix plant, or run on rough kaccha ground where extra ground clearance helps. Also think about the rental work near you, because that decides how many days the machine earns. So match the machine to your work: ARGO 2500 for small, close-by jobs at low running cost, ARGO 3000 for big pours and rough sites.
