    Looking to see if anyone in the cold weather shooting climates changes to a lighter weight oil in there Pat Traps. We are have a problem with two that want to keep cycling thru for 25 to 30 times before they warm up. I have tried adjusting the release timing with no effect, we also turn the machines on 1 hour ahead, with electric heaters (set on timers) in the traps that run for 2 1/2 hour before starting. Any suggestions! Temps are only single digits, not that cold.

    Thanks Gary DeSmidt, Hartford Conservation & Gun Club, Wisconsin

    Pat-Trap at one time recommended Mobil 1:OW-30 hydraulic oil. This was stated in the manual for the early SW models.


    At our four trap club we have SW series and the new G series. When we decided to change the hydraulic oil we contacted Pat-Trap and we were told to use Mobile 1:OW-20. (This is the recommended oil in the G series manual.)


    We were told to use Mobil 1:OW-20 hydraulic oil in all our machines SW & G models.


    With that said I believe the switch from 30 weight to 20 weight made a big difference. We turn our traps on 30 minutes before shooting and have no problems. This is without auxiliary heat and temperatures down to zero.

    We had a similar problem with our PATs and resolved it by putting a small space heater in the trap house and having that turn on by a timer about 8 hours before planned operation. Really haven't noticed a change in our power bill as a result. We talked about lower viscosity oil but didn't think we wanted to mess around with changing the oils out summer and winter.

    One of the unplanned benefits of using the space heaters is that now all of a sudden the trap help are motivated to keep the machines loaded and the houses cleaned out....

    0W-20 Mobil Syn is what we use. Actually we had problems with that oil cause it was "windmilling". Were told to make another adjustment that holds back the arm alittle more and that worked. Dave T.

    Make sure your arm brake is in good condition, Adjust the 2/3 switch,slight adjustment may help the wind milling. We added the heater and that pretty much was the key. Pats like warm oil..

    Gary,

    It's just like using a thinner motor oil in the winter vs. the summer in your car or truck. Thinner is good,and I agree with the Mobil 1 OW-20 oil for Pat Traps. Heat is your friend, but try to insulate it as best you can. We have a styro-foam enclosure around the pump & motor with a 100-W bulb dangling inside the enclosure on our SW. Ensure that the bracket for the cold weather is set correctly. Left (forward) slows it and right (rearward) increases the cycling. Also Charlie at Pat-Trap can help you with this problem as well.

    Good luck,

    Jon Reitz
