Re: 3pt hitch (Specs)
Don't know if they are ANSI specs. but here is what I understand of the cat. specs that apply to the Cat 1 size equipment which is commonly used. • Cat "1", apparently aimed at for 20-45 hp equipment; pins on top link bar 3/4" dia at both ends; bottom pins 7/8" dia. at implement with 26" spacing between pins being standard. Beyond that, everything varies, which is why 3-point hitch has flexible adjustments:• Dimensions on length of top link bars varies with implements you use but my bar usually is set at 24-25" long.• Lift pin heights above ground at implement vary also. Maybe 12"-18" above ground with implement sitting on ground.• Top link pin height above ground on some of my implements is 28"-36" above ground with implement sitting on ground. Commercial agriculture uses heavier Cat 2 or 3 specs. Light Cat 0 is sometimes seen on very small tractors but it is not very common. Cat 1 is readily available.
