PTO Speed

[tw4929]

I have a B-7300 with a small bush hog. When cutting grass, the RPM's are at max in the 540 rpm position which causes the engine to run very hot, almost pegged to red. Is is possible, or recommended, to use the 2500 rpm selection with a lower engine rpm? After about an hour mowing, this little engine is boiling hot.
Thanks for your help,

Not sure about the RPM's, but are you checking and cleaning the radiator while brush hogging? The radiators seem to clog up more during brush hogging than any other time for me. There are plenty of posts here on overheating due to clogged radiator fins and the damage that can occur.

I would think that machine should run all day with no issues, so long as engine room in good shape and not too much dirt/debris on the radiator fins, and fresh coolant.

when was the last full service last completed?

Changing the PTO speed range and running the engine slower will probably make the engine work harder and overheat faster due to changing the place on the power curve of the engine that it is operating at.
