Tractor Sizing...

[mml373]

You need to state whether your "disc cutter" is cutter only or mower conditioner. Puling a disc mower up grade can easily use all of 100 HP.

Mower only but I did notice that mower conditioners require much more hp (well, 100hp is a minimum). Not sure how my neighbor runs his on a MF165...
Is there such a thing as an adjustable slip clutch that goes onto the tractor's PTO between tractor and implement, so as to allow user to set up a slip point there before too much power would make it to the implement? Seems like a conservative option...if these are available.

We put up small squares for years with a 40hp tractor. We had bigger tractors but the AC D15 and WD did all the hay work.
When we went to a roller we put the 175 AC on it (about 65 hp).
