HT-974-16 and HT-974-20 transports are made for folding corn and forage harvester heads. The compact size and heavy duty construction features a thick wall upper bar and trussed lower bar to accomodate the extra weight of folding heads. The Heavy-Duty Series is available in both the 16' and 20' sizes. The low overall height allows the header to be placed on the tranport with ease. - Less
