71 Series Planter Unit by Yetter

Parallel linkages allow the 71 series planter unit to flex over ground contours and provides for a more uniform planting depth.   Adjustable down pressure springs take the bounce out of the row unit and can be helpful when extra down pressure is needed for soil penetration in tough conditions.   The real benefit of this feature is being able to add up 35 kilos of spring pressure in addition to the 50 kilo weight of the 71 series planter unit.   This compact, light-draft planter unit is ideal for fast, accurate planting.

Fewer stops to refill and more acres planted result from a large capacity 1.3-bushel seed hopper.   Each seed hopper is conveniently located at a height to make filling easy and fast.   Evenly spaced seed is accomplished through precision hopper parts and a positive ground drive.   Heavy-duty hopper support keeps the drive mechanism in accurate alignment.    Each ground drive is enclosed to protect its components from the elements.   Inside the enclosure a drive chain is utilized to connect the drive wheel to the seed plate drive, which makes for smooth running and accurate seeding rates.   The drive wheel plays three crucial roles in the planting process:   these being providing drive to the seed hopper, closing the seed trench while simultaneously gauging the depth of the seed.   By being totally self-contained, this drive configuration makes possible an endless selection of row spacings.

Setting the depth control on the 71 series planter unit is quick and easy, plus done without tools.   Simply pull a spring-loaded stop and a numbered cam can be turned to obtain a desired depth.   Each number on the cam scale represents 6.5 mm change in depth providing ample settings for most types of seed.  

Several options are available so you can fine tune the 71 series planter unit for maximum planting performance.
