Closing Recommendation
Pick the machine that fits your ground and your work. Choose the EarthMaster SX IV if you work on hard, flat land and want to move fast between jobs, with a deeper dig and smooth controls. Choose the EarthMaster VX if your ground is soft or sloped and you need more pull and grip, with a 4WD option for tough spots. Either way, first check that a Mahindra service centre is close, that spare parts and trained drivers are easy to get, and that the machine will sell well later.
So match the machine to your work: EarthMaster SX IV for hard, flat ground and fast travel, EarthMaster VX for soft or sloped ground that needs more pull.
