The 1345 replaced the 1340 in 2002. We have sold lots of this series and everyone is very happy with the units and have had numerous repeat buyers of the same model. They have been horrible parts business! But that's good for the customer. Basically the main things we sell are knives and the attaching hardware. As far as Conditioner Rolls are Number 1 seller is Rubber on Steel, then Steel on Steel. These are the same type roller you find in the Self Propelled Units used by commercial hay producers. The Hitch Type we sell is the Drawbar Swivel Hitch - our customer just love it. It gives you the double gearbox design of the 2Pt Hitch and excellent turning angle and simple driveline to the tractor - no heavy CV joint required making hook-ups easier. The other benefit is you can attach to tractor or it can be pulled by a truck. Out customers are taking a piece of 2" square tube and building a hitch to mount in truck receiver hitch and into the drawbar swivel hitch to transport machines if tractor is needed for another operation. The disadvantage our customer's have with the 2pt is you must use a tractor to move it.
