Compare Mowers
Discontinued model in this comparison: John Deere Z760RZTrak Zero Turn Mower (last listed October 2026). It is no longer sold new, and its price is the last one published rather than one you can pay today. The specifications are still accurate and still worth comparing against.
List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.
