I just bought a used 451 mower this weekend. I put it on the tractor and in 10 minutes was out doing some light mowing (weeds, road side grass). The sickle bar seemed to be set pretty high, so I thought I'd try to adjust it downward. The former owner said some things about the 2 arms that have slip fittings -- get them set and the heighth will be perfect.
Ok -- so, I undid the (2) 3/4" nuts and bolts on both sides, tripped the latch and tried some adjustments. I moved it way up -- the bar seemed at even steep (more upright) angle. So, I moved the grippers down on the arms back to about where they were. Now, I have a new problem...
On my Kioti, the stabilizers are attached with an eyebolt which is held in place with a large nut on the inside of the 3pt arm. That nut hits the gripper assembly on the mower. If I get one side on, I can't get the other side on - the nut hits the side of the gripper assembly. It's dark now (been working on for 2 hours!) -- I could try to post some pics tomorrow evening after work.
And with all of this up/down, jiggle that, move there. bang on this thingy ... it seems to me that I should have chosen an entirely different approach to setting the angle of the sickle bar. There's a couple lengthes of chain on the sickle bar attached to a threaded eye-bolt. If I unscrewed (lengthened) the eyebolt, my guess is that the sickle bar would lay down flatter.
Signed,
take 2 aspirin and maybe the banging in my head will stop...
