I did not ask this before, but how tight are your gates and field conditions. An inline has much more maneuverability, will not produce banana bales, is simpler to run and more efficient on power usage - less fuel costs. Equip it with an accumulator and grapple
Kuhns Mfg LLC | Innovation in small square bale handling. you can move a lot of hay quickly. I have one of their small 4 bale grapples and can pick the hay out of the field an stack it on my goose neck trailer at about 200 bales an hour - this includes loading and unloading twice. If you have the headroom at your store front you can also use a small grapple to load. My customers love it. All they do is adjust the stack on their trailers as I load.
My 4550 Hesston is a 2003 model (I think?), has had about 100,000 bales through it and in was in running shape when I got it 4 years ago. I had a major service done last year, new knives, etc, and the only issue discovered was guide rail wear, which were adjusted. Should be good for another 50,000 before they need replacing. Being a Hesston, parts AGRO, are readily available and some are interchangeable with the new MF line. In buying all my used equipment, the advice I got from the ranchers, is spend your dollars on a good baler. Most farmers/Ranchers only sell used equipment when it is worn out, so buyer beware. Mine was a trade on on a new MF inline 1839 - now 1840.
Massey Ferguson | 1800 Series Small Square Balers With the new 1840 standard bale size model, folks are trading up and there are some deals out there in the $10k range, but it will be worth it.
Hope this helps
