Outside Frame vs. Inside Frame
- Inside frames are more compact than outside frames.
- Inside frames are equipped with scraper rings to reduce rootball disturbance when
retracting the shovels. They are also used to press the rootball into the basket, thus
creating a tighter package.
- Outside frames offer more room for harvesting bushy or multi-stemmed trees and
- The majority of nurseryman are using inside frames, but deciding what is best
suited for your particular application is most important.
There are three shovel types – Truncated, Semi-Truncated, and Cone. The most popular
in the Nursery industry is the truncated shovel type because of its easy to handle shape
and size. All of our spades have a 25 degree classification regardless of the shovel
- Truncated – This shovel type is the shortest of the three with a relatively large bottom
enabling it to stand on its own.
- Semi-Truncated – This shovel type is a mix between the truncated and cone shovels.
These shovels offer a longer shovel depth; increasing the versatility and reducing the
- Cone – This shovel configuration is suited for applications where tap-roots and hard,
dry digging conditions are common. These spades are taller and wider but our compact
design minimizes the overall size.
Using one spade to dig several different sizes of rootballs is very important for some customers. This is
where the subject of legs and leg type presents itself.
Each spade is equipped with a gate locking feature in
the control valve.
- Spades 42” and larger are also equipped with a
mechanical gate lock to ensure the frame remains
locked during operation.
- Spades 40” and smaller do not have a mechanical lock,
for faster production efficiency.
