John Deere Won't Climb Hills: Hydrostatic Transmission Fix
A John Deere lawn tractor loses power on hills after 20–30 minutes of mowing. The cause is hydrostatic transmission heat fade. The fluid overheats and the transmission loses drive force. Documents the fix and the confirmed pattern across dozens of owner reports.
John Deere Riding Mower Stalls: Gas Cap Fix
A John Deere riding mower stalls after 15–30 minutes and restarts after sitting with the cap loose. The cause is a clogged vent hole in the gas cap creating a vacuum lock. Covers the diagnosis, the fix, affected models, and what to check when the gas cap is not the problem.
Sprinkler Pump Clicking Noise and Turning On and Off
A Berkeley irrigation pump clicked and cycled on and off by itself immediately after startup. Covers the full troubleshooting sequence — Rain Bird control unit, intake line, pump relay wiring — and the fix: a single wire that had vibrated loose from the relay contactor over years of operation. No parts replaced.
