How to Fix a 3-Point Hitch Seal Leak | New Holland TN70A Tractor Repair

This is a hands-on father-son repair of a leaking 3-point hitch lift arm seal on a New Holland TN70A, filmed because they couldn't find existing videos on the job. It covers draining the hydraulic fluid, removing the lift arm, drifting out the snap ring, housing, seal, bushing, and gasket, then pressing in new parts and reassembling both sides. Good for owners planning to DIY this specific repair themselves.

Appears to be a family-run DIY channel documenting a father and son working through an unfamiliar repair together, not a dealer or professional shop.
