Troubleshooting
Try the field fix first. Stop and call the shop for anything listed as 'Stop & Call.'
Stop & Call the Shop — Do Not Field-Fix These
- Any hydraulic leak on the Gravely — stop the machine immediately, tag out, do not continue
- Cracked spindle housing or spindle wobble under load — can throw a blade
- Belt shredding repeatedly or burning smell at the deck — suspect seized idler or misaligned sheave
- Oil leak from valve cover, head gasket, or crankshaft seal — don't top off; shop assesses the source first
Gravely-Specific Failures
| Symptom | Likely Cause | Field Fix | Stop & Call Shop If |
|---|---|---|---|
| Won't move / one side weak | Hydro release rods pulled to neutral, drive belt glazed or slipping, low hydro fluid, hot hydros | Confirm both hydro release rods pushed IN (engaged); let hydros cool 15 min if hot; inspect drive belt for glaze/cracks | Belt looks good, fluid fine, still won't drive — hydro pump or wheel motor failing |
| Blades won't engage when PTO pulled | PTO clutch electrical (fuse, switch, wiring), low battery voltage | Check PTO fuse, listen for clutch click when PTO pulled, confirm battery >12.4V | No clutch click and fuse is good — PTO clutch service |
| Won't start — no crank | Parking brake not set, PTO on, operator not in seat, dead battery | Check parking brake, PTO off, sit in seat, check battery terminals | Clicks but won't turn after good jump, or fuse blows again immediately |
| Runs rough / surges | Old fuel, dirty air filter, water in fuel | Clean air filter, drain and refill with fresh premium fuel | Persists after fresh fuel — carb or ignition service |
| Excessive vibration | Bent or unbalanced blade, debris wrapped on spindle | Kill engine, disconnect plug wires, inspect blades and spindle, clear debris, replace bent blades | Vibration continues with new balanced blades — spindle bearing failing |
| Smoke from engine | Blue: oil burning. White: water/head gasket. Black: clogged air filter. | Black: clean air filter. Blue: check oil. Stop machine for white smoke. | Blue or white smoke persists — engine service required |
| Any hydraulic leak | Hose, fitting, or seal failure | Shut down immediately. Tag out. | ALWAYS — do not drive it, do not top off and continue |
| BBC / spindle won't disengage | Safety failure | Shut engine off immediately. Tag out. | ALWAYS — no field fix |
