Just thought I'd pass along some info on the button on a Land Pride 3rd function joystick knob. One of my switches was not working sometimes and the red button had popped off. I'd have to fiddle with it to get it to work. My Kubota dealer wanted $40+ for the switch (pn 833-739C). I found that the same switch can be purchased from a electronics store for a lot less money. I ended getting my switch from Mouser.com (part number P9-411221) for $12.62. The Land Pride switch has Otto 21649 printed on the bottom of it. The switch that I ordered from Mouser has the same 21649 printed on the bottom of it. Just google Otto P9-411221 to see some online suppliers or go to a local electronics store and order that Otto part number. I installed mine today and it is the exact original Land Pride part(except the terminals that the wires solder to were slightly shorter). You will have to solder the wires to the new switch.
