I have a ford 1710 with a 60 inch KK II tiller attachment the tractor has a 3 cyl diesel with a 24 hp PTO. Tiller manual says not to lug the tractor when tilling. KK web site says 25 to 40 HP recommended PTO HP.
OK onto my question. I set the RPM to 2400 which is the 540 PTO speed. Put the tiller in the ground and start tilling. The RPM will drop some 100 - 200 rpms and to get it back to 540 PTO speed I give the tractor a little more throttle. To me this would seem normal for a tractor doing work.
When is to much RPM drop a problem? What is considered lugging? To me a lugged engine would blow black smoke from the exhaust and have quit a bit of RPM loss.
