I'm experiencing a bit of an M7060 (2018 model) Issue when bush hogging.
I Set PTO speed to 540. Once I begin cutting it will usually drop to about 525-530. Fluctuates mildly while cutting, depending on up or down hill, etc.
Will run well for about 1.5 - 1.75 hours. Then it will begin to bog down. Changing to lower gear will bring PTO speed back up. Then it will bog again. Eventually, It will have to be in 2nd or 1st gear to keep PTO speed up, even in sparse grass.
Once it gets in this state, engaging one of the rear hydraulics (lift rear or wings of mower) will also bog the engine down dramatically.
When first starting up today, I verified that engaging one of the rear hydraulics does not bog engine down while functioning normally.
It has done this with both a 12’ wing mower and the 10’ offset mower. I hooked the wing mower to our L5740 and it cut the same area without difficulty.
Both tractors use fuel from the same transfer tank.
It has been doing this for about a week. I park it overnight and it seems to be fine the next day, for 90 minutes or so. Then, same symptoms.
Things I’ve tried:
Throughly cleaned all radiators
Changed both inner and outer air filter.
Drained the water separator.
Verified sufficient hydraulic fluid.
A friend has a neighbor that used to be a tractor mechanic. He explained the symptoms to the neighbor who said "It sounds like a sensor that may have gone bad. Whatever it is is something trying to protect the system".
Has anyone out there experienced anything similar? Any ideas before I have it taken in to the dealer?
Thanks.
