I have a 2006 TC45DA and have had problems with the parking brake letting go from the first days that I owned it. It had 190 hours when purchased, but had only been used to pull an orchard wagon. It now has about 550 hours. I am very familiar with all the tricks of trying to get it to set, but now it will not set at all. I have looked at the mechanics, which are very simple, probably too simple. Does anyone know if there is any parking brake adjustment? I don't believe so. I am thinking that I may need to replace the ratchet plate. I asked a similar question on the general Repair category, but am hoping someone in the NH discussion will have a more specific answer. I don't understand why my local dealer's service department says this is a rare problem, considering the prevalence of this design on NH tractors. Thanks for any help.
