on the seat is two wires to power seat and two wires for safety switch, hook these two wires together and machine will run,or a big rock or your wife or girlfriend or father or or or.dale
Belt will feel loose even when everthing is right if machine has been running lately. You can slow rotor all the way and then back off the very long bolt that has grease zerk in it. This will expose the cams but I doubt you have a problem there if you have greased like you said. I grease the zirk in bolt until you feel restriction with varible slowed all the way. Grease the offset zirk a few shots a day. Be sure you have things in place and tighten large bolt very well. I'd watch RPM of cylinder to see when vibration starts. Do this in High range and low range and with varible speeded all the way up and use the throttle to check when vibration starts. This will help a bunch to determine what is causing your vibration. Report back with all your findings and we'll try point you in the right direction. Good luck
Check the bearings going into the gear box as well as the bearings on the main shaft. I had a bad vibration this yr and my rotor belt was jumping. I thought the same thing that you did. I was looking things over after i had greased it and things were fine. I continued harvesting when i had flipped my rotor belt and blew it apart. When I was pulling the belt out of the pulleis I had a little play in the main shaft. After looking at it more closely i saw that i had alot of up and down movement on the main shaft as well as the gear box end. After replacing all bearings on the main shaft and the gear box as well as a new belt(2nd one with in 12 hours)I went on to put 350 hours on it with out a problem. R72
