    Found a solution for Pat TRaps windmilling targets in cold weather. Granted So. CA. does not get very cold, but at 40 degrees the Pat Traps will windmill targets even after "warming up" for an hour. Golden West sells oil pan heaters. This is a heat patch that goes around the reservoir and immediately heats up the fluid. At NHSC we used 5" hose clamps to keep the patch around the reservoir. ONLY RUN THEM FOR 15 TO 20 MINUTES as they get very hot. The test came today, Saturday, at the ATA shoot. Three traps had the heat patch and not one windmilled target. The one trap without the heat patch
    windmilled targets off and on for an hour. Contact Golden West, Mike or Chuck, for the patch. Fred

    You might check with Pat-Traps. Our old sw model machines called for a 30 weight version of hydraulic oil. Pat-Traps now recommends a 20 weight oil for all machines.


    We changed out the hydraulic oil in our four machines to the 20 weight version and have had no problem. Two weeks ago it got down to 14 deg. F here in central Indiana and we had no problems with windmilling. We did let them warm up for 30 minutes first before throwing targets.

    We are using an even thinner synthetic oil and even after running for an hour still have windmilling problems in So. CA. The heater pads solved the problem in 15 min. Fred

    That's good to know Fred, because our club in Idaho was thinking about getting a Pat-Trap, but is hesitant to do so because of the cold weather, esp. if you're having problems with the cold in sunny Santa Clarita!

    Synthetic oil, warm up time, and adjusting the arm stop will supress windmilling.

    A 10 to 15 Minute warm up and adjusting the cold weather switch is all that is needed. The Pat trap is by far the best machine on the market.

    Magnetic Engine Block Heaters work well too.

    Don't know the name of the heater patch, but it is so simple to attach and it works so quickly. What "cold weather" switch are you taliking about? Golden West did not mention anything like that. Jennifer: Definitely get the Pat Trap with the metal reservoir [the plastic will melt] and attatch the heater pad. Give Golden West a call and talk to Mike Elton. Fred

    We put a simple shop drop light next to ours. Temps down to 30°F and 15 minute warm up worked like a charm.
