I've done eight Lombardy Poplar. They were piece of cake. Also have done some
Redbud. Russian Olive, a couple Apple and several species of Pine. ... around 40 total in all over the past 4-5 years....IIRC
Never did the scoring as mentioned in the title. I'd have to agree with 4570 Man on that....now that I think about it.
Cheers,
Mike
BTW...Leo....your tractor has more PTO HP than mine. But if you use a Quick Hitch, be sure to use some bushings for a snug fit on the 3 point. It is less likely to jerk around back there.... for a newby.
