I have a 1999 B21 TLB hydrostatic with approx 2400 hours.
It starts and runs great. However, when it's cold and I start working, say at 2000 rpms, when I hit the pedal to go forward or backwards it drops to about 1750. It will stay at 1750 while I'm working, but if I stop moving it goes back up to 2000. That's when it's cold, for about 15 minutes.
When it's warm, the rpms will go up while I'm working to about 2000, but when I come to a stop it will rev to around 2200.
At any temperature if I start pushing, pulling, or lifting big loads, it will belch some smoke like the governor is kicking in, and of course I can eventually kill it if I don't let up
Any ideas as to why the rpms fluctuate? I would think if I set it to 2000, it should stay there regardless of stopping or going, hot or cold.
Thanks in advance for any suggestions or opinions. If you need more info let me know.
Rick
