I used a tiller on my Jubilee for several tears till I got different tractors. I was told it wouldn't work but it was fine. It was a little fast I had to be in 1st gear 2nd was too fast period but you will have to go over it several times to chew it up better because of going a little faster.
This just how it worked for me. I also used the same tiller on the 841 lots more power but still the same speed, of course neither one of them had an independent PTO so if I stopped I always picked the tiller up because well because it stopped.
