Late 90s early 2000s Hesston 1340 discmower thoughts?

There is a pretty good deal of a Hesston 1340. He’s asking $2250. It’s been used but it works. The bolt and nut And bushing holding the gear between the turtles fell out and needs a new one. He says he changed all the bearings last winter. New drive pulleys and a new gearbox. Only thing he didn’t change is anything on the cutterhead. I plan on Expanding to A Couple hundred acres. Will it suit me well? is it worth the deal or is it junk? It’s going to be a big upgrade from my haybine. What things break the most?
Any info is greatly appreciated.
