Deck Belt Inspection & Replacement
| Step | Procedure |
|---|---|
| Access | Disengage PTO and lower deck to lowest position. Disconnect front draft rod, rear lift links, and PTO clutch wire connector. Slide deck out from left side. |
| Inspect | Check for glazing (shiny hard surface), cracking across belt width, fraying on edges, or chunks missing. Press midspan — should deflect 3/8"–1/2" under 5 lbs. Stretched or glazed belt slips under load. |
| Replace | Route new belt per routing decal on deck shell (separate mule-drive and deck-drive belts — replace the one that failed). Seat all idler pulleys and belt keepers before testing. |
| Test | Reinstall deck. Test PTO at low throttle. Belt should not slip, squeal, or smoke. Verify deck level has not shifted. |
Troubleshooting
Try the field fix first. Stop and call the shop for anything listed as 'Stop & Call.'
Cub Cadet-Specific Failures
| Symptom | Likely Cause | Field Fix | Stop & Call Shop If |
|---|---|---|---|
| No crank, headlights work fine | Brake pedal not fully depressed, PTO knob not OFF, seat switch not triggered, blown starter solenoid | Press brake fully, push PTO knob in/OFF, sit fully in seat, try again. Wiggle seat switch connector under seat. | All interlocks satisfied and still no crank — solenoid or starter |
| Engine dies when leaving seat or engaging PTO | Operator presence/seat switch (by design), or seat switch failing intermittently | Normal if leaving seat with PTO on. If dies while properly seated, check seat switch connector. | Dies while properly seated and connector is clean — switch needs replacement |
| Deck belt slipping or smoking | Glazed or worn belt, seized idler pulley | Inspect belt and idler | Belt replaced and still slips — idler or spindle issue |
| Won't start — no crank | Safety interlock not satisfied, dead battery | Brake fully depressed, PTO off, sit in seat, check battery | Good battery and all interlocks satisfied — solenoid or starter |
| Uneven cut / striping | Dull blades, deck not level, uneven tire pressure | Sharpen blades, equalize tire pressure, check deck level | Deck still off after corrections |
