Warranty terms vary by dealer, region, and purchase date. We recommend confirming current warranty coverage directly with your dealer before making a purchase decision.
Before purchasing, verify dealer pricing and availability in your area, confirm current warranty terms, test-drive if possible, and assess which implements or attachments you'll need. Both specs and pricing can vary by region and dealer.
