/ Troubleshoot Belly Mower Issues #1
Gotten into this world late and need help diagnosing an older Kubota belly mower with issues. I use a Kubota B2400 ('96 vintage, +2000 hours) and RC54-24B mower to take care of the weeds on a former bean field, so this occasional task may be too much for a finish mower, the deck clogging at intervals. Beginning last season, very intermittently, the mower began leaving the middle uncut. I though the middle blade was probably the problem. It was fairly infrequent and the job got done with a few extra careful passes. By late summer, it was the norm and not the exception. This spring I replaced the belt with an OEM Kubota belt when one of the two (!) v-belts broke, thinking that might be the cause of the issue. With the correct belt, the mower runs quieter now, but now the problem has worsened to the point where the mower is virtually ineffective. Present status: PTO operates, blades freely spin, but very little cutting is happening at best, (though full operation does happen very infrequently/unexpectedly), and total inop - with pto engaged - now part of the mix. Note: full operation is accompanied by increase in operational sounds. I tried disengaging/engaging pto several times which at first seemed to make a difference. The pulley doesn't seem to stop spinning, from what I can see, which is the opening for the left Zerk fitting. Also tried varying the pto speed, to no effect. The issue seems more than bad blades or dirty deck, but I don't know enough about the mechanics of the operation to puzzle it out. Any suggestions would be welcomed.
