While I have some time here's a little more information.
I use an Oliver radex 2 bottom 16" plows for years now behind a WD Allis and or an H.
I use a NH 477 Haybine Used a NewIdea number 30 sickle mower for years.
This year By far was some of the best hay, cut 725 Bales in 1.5 hours, with D-19 Allis and the 477 haybine.
Using the sickle mower you will need about 5-6 more hours of drying time. But I think they make a little better hay. I know allot of guys that don't set the rolls on the haybines, they wring there hay too much when cutting it.
Need to get a good old grain drill for seeding steel or wood wheels ok as long as sound and useable< I still use an old oliver 46 graindrill on steel.
Some type of packer if you plan on aflafla. Need a good bed to seed aflafla.
Cost of planting a new hay field with aflafla in pricy. Seed, fuel, time, fertilizer, lime, can be hard to make ends meet. Takes me and average of three years to start to make good money from a hay field. But we are only getting about $3.00 a bale, If I could get around $4.00 I could just about do it full time a make money.
Hay normally makes one to two good cuttings and up 2 more so so cuttings. I average around 5-7 tons per acre. But work stops me from getting first done on time. I normally can't start until 10-15 of June and should start 2nd or third week of May.
One hay field I planted just to try was weeds and small trees, a wetter mid summer, I disked it mowed it let it sit about a month mowed and disked again two weeks later disked it again and packed it and than planted Aflafla and Timothy, work out just a well as plow ground. Like I said it had small trees in it but they are all gone now , some years year later. We did fine a few small trunk pieces in the field, had to chainsaw a few trees, about an acre of over ground field that was not cut or planted for so 10 years or so. .
