How and When to Change Your Bush Hog Gear Box Oil

Distinct for its practical side tips rather than just the fluid swap itself: Mike explains why gearbox oil turns milky (condensation in half-filled housings), demonstrates sucking oil out from the top when there's no drain plug, names the exact tools and fluid (2 qts of 80-90 gear oil, 5/16 Allen wrench, 7/8 wrench), shares a paint-pencil labeling trick for tracking maintenance, and mentions the old-farmer workaround of packing a leaky gearbox with flowable grease. Best for first-time bush hog owners doing their own maintenance.
