Whatever brand you buy be sure you can get replacement parts. These machines are getting older maybe 30 years.
Talk with some guys that have used cycle mowers verse the new type disc mowers (I do not know the correct terminology that they are called)
But from years of experience an old worn cycle mower and hay baler can cause you a lot of trouble.
You can get by with and old disc, plow, cultivator or even hay rake.
But you want to buy the best hay cutter, baler and corn picker you can afford.
Maybe a smaller round baler might be a better choice, easier to move the bales.
New Holland and John Deere always had a good reputation in farm equipment, but condition is everything.
Worn out is worn out, no matter the brand!!!!!!
