Description
Prevent fatal rollover accidents when operating commercial turf mowers on steep ditch banks and retention basin slopes. The Toro Roll-Over Protection System Kit provides structural operator protection for TimeCutter HD zero-turn riding mowers. This safety kit includes a folding tubular steel roll bar. It requires frame bolt installation using hardened grade 8 structural hardware.
Heavy-gauge tubular alloy steel forms the roll-over frame, absorbing severe impact forces without brittle joint fractures. The folding upper bar pivots down via steel detent pins, allowing clearance under low tree branches and shed doors. A retractable seatbelt assembly anchors to the mower chassis, holding the operator securely inside the roll-safety zone during machine tip-overs. Powder-coated exterior finishes resist corrosive fertilizers and turf chemicals.
Key Features of Toro 139-2638
Landscape contractors install this ROPS kit to meet municipal jobsite safety standards and OSHA requirements. The folding hinge permits mowing under low-hanging orchard trees.
- Structural tubular steel frame provides rollover survival space for commercial mower operators
- Folding hinge design lowers roll bar height to clear low garage doors and tree limbs
- Retractable two-inch lap seatbelt holds operator within the protective frame zone during roll events
- Meets OSHA 1928 and ISO 21299 commercial turf equipment rollover safety standards
- Heavy-duty steel mounting brackets bolt to factory chassis holes without frame welding
- Steel quick-release pins lock the folding roll bar in upright or lowered positions
- Corrosion-resistant powder coating shields steel tubing against damp grass clippings and rust
Roll Bar Structural Crash Telemetry
Hydrostatic pull testing confirms 4800 lbs of lateral load retention before 2 inches of frame deflection occurs. Longitudinal impact testing absorbs 6200 foot-pounds of kinetic energy without structural weld tears. Hinge pivot pins resist shear forces up to 14500 lbs under dynamic crash simulations. Seatbelt retractor mechanisms lock within 0.02 seconds of sudden chassis deceleration. Frame coating tests withstand 500 hours of continuous salt-spray exposure.
Rollover Safety Rules Operating Boundaries
Lock the folding roll bar in the upright position and fasten the retractable seatbelt whenever mowing slopes. Lower the roll bar only when clearing overhead tree obstructions, and unbuckle the seatbelt in lowered mode. Never operate mowers on slopes exceeding 15 degrees angle without certified ROPS equipment installed.
- Chassis mounting bolts require torque checks to 65 foot-pounds every fifty mowing hours
- Hinge detent pins demand light multi-purpose grease application every season
- Seatbelt webbing requires visual inspections to identify cuts or chemical degradation
