Anybody have trouble braking the knifeheads completely off. We have broken 3 in 3 years. When we turn the belt manually the sickle runs smooth. might get a good welder to try to bulk up the 2 welds on the knife head

We had this several years back after we spent a few dollars fixing up a series 2 flex head. We replaced the skid shoe under the wobble box and we started breaking knifeheads, 3 in one field of wheat. Turned out to be the shim washers weren't just right and the knifehead bolt would make the slightest contact with the new shoe and snap it off. Hope this helps.

stabilize the skid shoe by welding a Z bar or a couple of angle pieces under the box running from left to right. The box is leaning over and snapping it. Later heads from Gleaner are BEEFED . You can weld yours as there is plenty of room.

Sometimes it can be the stabilizer bar underneath the gathering sheets that has a bad tie rod end and is letting the box lean like tbran said.

Do you have the Variable-Speed corn header drive????.... if so, are you slowing it completely slow and disconnecting the hose on the top sheaves so it stays slow???????? The sickle drive will explode if it's sped up from the slowest speed on a V/S drive....and make absolutely sure you're not getting reel teeth into the sickle as well.
