You can damage the tractor from repeatedly overstressing it. As a general rule you should be able to pull the load without bogging the tractor down. It does wear on the drivetrain. If you're on level ground with good traction you will stop a tractor before it spins the tires. If you are constantly bogging the tractor down you are either in too high of a gear or you are doing too much for the tractor. The hardest wear on the tractors is the shearing effect from too much stress on the pto.
As far as idling goes it is hard on any diesel engine to idle at the same speed for an extended period of time. All of the trucks and even most pickups now come with an auxillary idle controller. What this does is vary the rpms so you are not constantly idling at the same rpm's.
As far as rpms you aren't going to do anymore damage on a tractor at the pto speed or at a lower rpm. The tractors will not redline. They are governed from the factory in most cases to not exceed the max rpms. That's why on tractors you don't see a red area like you do on cars and pickups on the tach. What you will get with the lower rpms is increased fuel savings. That's why deere came out with the e-pto. It lets the pto operate a lower rpm to conserve fuel. But as far as running at pto speed or lower rpms your engine will last the same.
