MODULE 2: OIL & MAINTENANCE LOOKUP

🛢️ Engine Oil Capacities & Maintenance Intervals

Engine Brand Oil Capacity Recommended Oil Type Blade Sharpening
Honda (GCV160, GCV190, GCV200) 18 – 20 oz (0.55 L) SAE 10W-30 or SAE 30 Every 25 Mowing Hours
Briggs & Stratton (140cc – 190cc) 15 – 18 oz (0.44 – 0.53 L) SAE 30 / Vanguard 15W-50 Every 25 Mowing Hours
Kohler Courage / 7000 Series 32 – 64 oz (1.0 – 1.9 L w/ filter) 10W-30 / 10W-40 Synthetic Every 50 Hours (Filter + Oil)
Electric / Battery (EGO, Ryobi) 0 oz (No Oil Required) N/A (Battery Electric) Every 20 Mowing Hours
🛢️ Pro Tip: Honda walk-behind engines do not have a bottom drain plug. Tilt mower on its side with the dipstick tube pointing down into an oil drain pan when engine is warm.
MODULE 3: CUTTING HEIGHT & SCHEDULE

✂️ Grass Species Height & Mowing Frequency

🌱 Cool-Season Grasses (Fescue, Bluegrass, Ryegrass):
  • Tall Fescue: 3.5″ – 4.0″ (Set deck high in summer to shade roots)
  • Kentucky Bluegrass: 2.5″ – 3.5″ (Mow every 4 – 6 days in active spring growth)
  • Perennial Ryegrass: 2.0″ – 3.0″ (Mow weekly)
☀️ Warm-Season Grasses (Bermuda, Zoysia, St. Augustine):
  • Bermudagrass: 1.0″ – 2.0″ (Frequent low cuts encourage dense lateral growth)
  • Zoysia Grass: 1.5″ – 2.5″ (Mow every 5 – 7 days)
  • St. Augustine Grass: 3.5″ – 4.0″ (Keep tall to prevent weed invasion)
✂️ Rule of Thirds: Never cut off more than 1/3 of the grass blade height in a single mowing session. Sharp blades prevent torn, brown grass tips!
