| Hi all,
I am a long time follower first time poster. I have a project planter that I have slowly been building over the last two years and I am at a point where I have questions that can’t be answered using the search function. I use this planter for a small business where I plant sunflowers, corn and sorghum for landowners to hunt over. I have planted sunflowers with 2 row Biggs planters, pequae, and all the way up to a vacuum/strip till rig so I know what is possible with a finger pickup in terms of singulation. My question is this: with an older planter and finger meters what parts are most critical to replace for maximum singulation? I picked my girl up at a junkyard and have since replaced about everything on it but I feel like it doesn’t do near the job with sunflowers that a rebuilt Biggs or Pequae does. Here is a list:
-Shoup Parallel arm bushings
-Closing wheels upgraded to T handle with eccentric bushings and yetter cast twisters (1 per row, the opposite being rubber tire)
-precision meters (corn fingers, my guy at PPS swears the sunflower fingers don’t help with #2 SF seed)
-seed tubes
-hoppers
-DD openers
-down pressure springs
-added yetter floating row cleaners with DD liquid fert knives (putting starter and fungicide in 2x2)
Also added a sprayer system so I can put down pre out the back.
Am I wasting my time thinking there’s anything else I could do to improve? The shanks have a little play in them even after parallel arm bushings so I’m afraid I need to get new parallel arms. I’ve also looked in to seed firmers but I don’t know anyone using them.
