Simplicity Courier/Contender zero-turns are known for comfort-focused features and homeowner-friendly handling, often including suspension elements that smooth rough yards. A representative new price is based on Simplicity's published Courier MSRP table (typical mid-spec models around the $4k range).
If a rear suspension leaf spring snaps, repair is usually the right call when the mower is otherwise healthy: replacing the spring/hardware and checking the opposite side for fatigue can restore ride quality for far below the 40% threshold. Replacement becomes more attractive when suspension failure coincides with structural corrosion around mounting points, repeated deck spindle problems, or hydro performance decline-stacked issues can erode the value proposition.
Because suspension parts affect handling and stability, prioritize a proper OEM-grade repair over improvised fixes. After repair, reassess mowing technique on rough terrain to reduce repeated shock loading and extend component life.
