Isuzu NPR
Lawn · lawn
Cab-over diesel flatbed landscape truck — the primary mower hauler. The Gravely Pro-Turn 160 and Toro TimeMaster 30" both ride on the NPR via ramps. DIESEL ONLY — putting gas in this truck destroys the injection system. Know the ramp procedure, tie-down rules, and pre-departure checklist before every load.

Fuel
DIESEL ONLY. Putting gasoline in this truck destroys the fuel injection system — it is not a simple mistake to fix. Know the fuel cap before you pull it.
- Ultra-low sulfur diesel (ULSD) only — the only fuel this truck burns
- No gasoline, no ethanol blends, no unleaded — diesel only
- No biodiesel above B5 unless the shop has approved this specific vehicle
- Fuel above 1/2 tank before rolling — do not run low on diesel mid-route
- If you have any doubt about which can or pump you're using: STOP and verify before opening the cap
Wrong Fuel = Destroyed Injection System
- Gasoline in a diesel engine contaminates the entire fuel system — injectors, pump, and lines
- The repair cost is thousands of dollars and puts the truck out of service for days
- If you put the wrong fuel in: do NOT start the engine; call the shop lead immediately
Ramp Loading Procedure
Follow this procedure every time. Ramps are unforgiving if you turn on them or skip the pins.
- Park on level ground; set parking brake; place wheel chocks if any grade
- Pull ramps fully out and pin/lock them — check that ramp ends are flat on the ground, not bridged on a curb
- Drive the mower up slowly and STRAIGHT — never turn on the ramp
- Gravely: both hydro release rods must be pushed IN (engaged) during loading
- Once on the flatbed: park, set parking brake, PTO OFF, ignition OFF, key out, fuel cap tight
- Fuel shutoff to OFF where equipped (Toro has a shutoff — use it for transport)
- Tie down before stowing the ramps
- Stow and pin ramps before driving
Tie-Down Rules
Federal cargo securement (FMCSA) rules apply on public roads. Follow every point — there are no exceptions for short trips.
- Minimum FOUR anchor points per machine — one strap to each corner
- Aggregate WLL (working load limit) of all straps must be at least 50% of the machine's weight — read the tag on each strap; retire any strap with a missing or unreadable tag
- Run straps over solid frame members ONLY — NEVER over: hydro release rods (Gravely), fuel lines, fuel tanks, plastic shrouds, seats, or steering wheels
- Ratchet snug — compress the suspension slightly but not so tight you bend a frame member
- Re-check straps after the first 50 miles or first stop, whichever comes first
Pre-Departure & Post-Transport Checklist
Walk the truck before you drive and again before you unload.
- PRE-DEPARTURE: All straps tight, ratchets locked, strap tails secured (not flapping)
- PRE-DEPARTURE: Ramps stowed and pinned
- PRE-DEPARTURE: Fuel caps tight on every machine; oil caps tight
- PRE-DEPARTURE: Fuel shutoffs OFF on machines so equipped (Toro)
- PRE-DEPARTURE: Deck cleared of grass clippings (loose clippings become projectiles at highway speed)
- PRE-DEPARTURE: Trimmers, blowers, and hand tools in racks or boxes — nothing loose on the flatbed
- POST-TRANSPORT: Re-inspect all straps before releasing any of them
- POST-TRANSPORT: Release straps in order — do NOT release all four before the machine is ready to move
- POST-TRANSPORT: Walk around the truck for dropped tools or strap tails caught under tires
