100-140 Fast Hitch: Helper Spring

Sun Nov 13, 2011 9:43 am

. Was the helper spring--that runs from the side of the tractor ahead of the LH fender to the inside touch control arm-- for the fast hitch standard or optional? I have seen a couple tractors that didn't have it, some being Super A's that got a fast hitch added on later in life. Always assumed it came standard but that got me wondering. How much does it help as far as lifting capacity goes?
