The Z997R and Z998R Diesel ZTrak™ Mowers feature a standard air‑suspension seat designed to maximize comfort with extensive adjustments for operator size and preference. Operators can fine‑tune weight, height, seat ride stiffness, lumbar support, back‑angle tilt, and fore‑aft positioning to achieve a smooth, ergonomic ride. Durable armrests, resilient seat cushions, a raised seating position, and a convenient retractable seat belt further enhance comfort and ease of use.
The Z998R Diesel ZTrak™ Mower features a turbo‑charged, 3‑cylinder diesel engine delivering 43.4 hp and meeting Final Tier 4 emission standards through an efficient DOC/DPF system. Its design emphasizes fuel economy, low noise, strong torque, and long engine life, supported by components like direct fuel injection, full‑pressure lubrication, and a dual‑element air cleaner. Additional conveniences—including an auto‑bleed fuel system, easy‑access cooling components, and isolated engine mounting—enhance reliability, serviceability, and operator comfort.
The Fastback™ PRO rear-discharge system improves safety and productivity by minimizing debris throw and allowing closer mowing near obstacles. Ideal for public spaces, it ensures a tidy operation with better debris control around the operator.
