First since the metros are belt, how well do the ecs controls work? Is it similiar to the pistol style? secondly, i know to change heigth you must move the axle and the front caster spacers. How much height can you change with just the front caster spacers and not get it out whack?(like 1/2" or what) I am considering the exmark metro 48 and the gravely pro g 48. I like the ecs on the exmark, but dont like the heigth adjustment. I like the heigth adjustment on the gravely but it only has the pistol grips. I assume the quality of cut will be similiar?? So comments on the ecs vs belt, exmark height adjustment, and gravely vs exmark cut quality, build quality, ease of operation.. LAteer guys!!
