Notes

Gravely ZT HD and Pro-Turn models are heavier-duty zero-turns often chosen for large residential properties or light commercial work where a fabricated deck and robust hydros matter. A representative new price is based on current dealer pricing for a ZT HD-class 52-inch unit, with Pro-Turn trims varying by deck and engine.

Spindle bearing "noise/grinding" is typically a repair-first issue when caught early: replacing bearings (or complete spindles) and inspecting blades for balance can restore cut quality and prevent deck damage. Replacement becomes more compelling when spindle problems repeat due to deck shell cracks, severe corrosion, or if multiple spindles plus PTO/clutch issues stack up near the 40% threshold.

Also consider usage: high-hour machines may justify a more comprehensive rebuild, while lower-hour units are usually worth repairing to protect the investment.
