Heavy‑duty 4.5×16 inch spoked gauge wheel assembly with a cast‑iron spoke hub and durable rubber tire, designed for planters, seeders, and grain drills. The open‑spoke design helps shed soil and residue to reduce plugging, and the standard double‑roller bearing (5203KYY2) with sealed hub ensures smooth rotation and long service life — ideal for maintaining accurate planting depth and consistent seed placement under challenging field conditions.
