Stump Jump Tyne Units

Stump Jump Tynes in 450lb to 800lb Breakout

Boss Agricultures Stump Jump range of units are equally at home in direct drill, zero till, minimum till or conventional cultivating applications. Incorporating many of the features that our parallelogram units have the row unit offers flexibility through its design to deliver a planting/cultivating unit that is tough and simple to operate & maintain.

The Stump Jump range includes:

  • SJ45 offers a 450lb breakout on the tyne trip and is available with a ⅝” x 2” cultivating shank or ⅝” x 2” planting shank as required.
  • SJ65 offers a 650lb breakout on the tyne trip and is available with a 1” x 2” cultivating shank or 1” x 2” planting shank as required.
  • SJ80 offers an 800lb hydraulic breakout on the tyne trip and is available with a 1” x 2” cultivating shank or 1” x 2” planting shank as required.

Boss Stump Jump Row Units Front to Back:
The front mount clamps diagonally to an RHS toolbar to ensure the unit locks in and is not able to twist on the frame; this also means the unit can be easily repositioned on the toolbar if required.

Boss Agriculture SJ65 row units on 375mm row spacings

Fitted with a heat treated spring steel low draft tyne with pin adjustable depth control in ½” increments. The tyne assembly has a removable seed boot which means it can be easily replaced with different attachments, or simply pulled off to be hard faced back in the workshop without removing the tyne. The tyne box assembly is heavily constructed to handle the constant load it operates under, again fitted with replaceable bushes and 1¼” chrome plated pins on an extra wide pivot for extended life and simple replacement.

The Stump Jump press wheel assembly is a robust assembly with some unique features for ease of operation and longevity. The press wheel pressure is pin adjustable with a positive locking pin that self locates when increasing or decreasing the press wheel pressure. The main press wheel arm pivots on a central boss that is located in-line with the press wheel & tyne box assembly to increase operating life and reduce maintenance requirements; this pivot assembly is also fitted with the same replaceable bushes and 1¼” chrome plated pins used throughout the row unit. The press wheel assembly is available in both a fixed and pivoting assembly depending on your application. Press wheels are fitted to a greasable Holden hub and available in solid or pneumatic with a number of different profiles to choose from.

When optimum planting conditions are available or you want to run fertiliser in with minimal disturbance an optional Boss double disc shank can be used by simply replacing the tyne with the disc shank. The double disc offers very low disturbance and will run in heavy trash conditions whilst delivering excellent moisture & fuel savings. The double disc shank can also be fitted with vee press wheels.
