If I put direct drive on a 9560sts will it be able to handle an 8 row head with a chopper?

I would think that it would be able as it's a 60 series machine so it has some more HP than the 50 and it can handle a 12 row just fine, I would say it couldn't hurt it
It depends what type of head. The JD choppping head , (stalkmaster) is the same design as the italian cressoni and drago as well as the hungarian harvestec. These all rely on the old lawn mower blade technology which Geringhoff abandoned in the early 80's. Of the many disadvantages, the lawn mower blade design results in an average increased horsepower draw of 30%. The Geringhoff ( uses a completely different design which only demands an additional 2 hp per row. Geringhoff only suggests a direct drive when using heads which are 12 rows plus. If using a Geringhoff, your 9560 should have plenty of power even with the variable speed drive which is supplied as standard equipment on the 9560. If you buy a lawn mower blade chopping head, (unlike the Geringhoff) you'll need to buy a direct drive.
If you want everything cut all the way to the ground, then you will have to get out the old lawnmower.

I don't want anything cut at all.
I have been using 8 row harvestec for years,,,,switched to direct drive on a 9650sts 4 yrs ago....plenty of power,,,unload on the go with full tank with extension in very very wet conditions..
If you have the HD reverser setup you might be ok,but in most cases your going to need the fixed drive if you dont want to be blowing belts all day long. Oh and that goes for the gerringoff as well,if its a chopping head, it takes power to chop stalks reguardless of design.
i disagree, ran a 9560 sts with an 8 row geringhoff rotadisc for 1000 sep hours without taking out one drive belt, just run the head as fast as it will go and you will be fine
Maybe your condition are different in SE SD I have had a couple customers in the past who had a 9650W and a 9560 with 8 row 30 gerringoffs and we could not keep belts on them even with backshaft speed all the way up. If it were my machine I would put the High Torque conversion drive to keep it a variable speed.
