Which one should you buy?
Match the tractor to your heaviest regular job. If you run a reversible plough, a loaded trolley or a potato planter, lifting capacity matters most. If most of your work is rotavator, thresher or pump, compare PTO HP. Then get on-road quotes for both from dealers near you, and check how far the nearest authorised service centre is - for a 10-year machine, service distance matters as much as a few HP.
