CHOOSING THE RIGHT TREE SPADE
Lemar has manufactured a variety of tree spades to suite your business’ needs. As the series numbers increase, so does the capacity for the tree spade to dig larger root balls.
Outlined below are the key features to help you choose your best spade.
Reading the Model Number
The model number is used to classify five different things:
5 – The series designation – example: 5 = 500 Series
26 – The actual maximum plug that the spade will dig in inches
3 – The shovel configuration – 3 blade or 4 blade
i – Frame classification – inside or outside frame
t – Blade type: t- truncated, st- semi-truncated, c – cone
Inside Frame vs. Outside Frame
Inside frames are more compact than outside frames.
Inside frames are equipped with scraper rings to reduce root ball disturbance while retracting the shovels. Scraper rings are also used to press the root ball into the basket, creating a tighter package.
Outside frames offer more room for harvesting shrubs, bushy, or multi-stemmed trees.
The majority of nurseries are using inside frames. However, choosing the frame best suited to your particular application is most important.
All of our spades have a 25 degree classification regardless of the shovel configuration
Truncated – a relatively large bottom enables this shovel type to stand on its own. It’s easy to handle shape and size makes it the most popular in the nursery industry.
Semi-Truncated – this shovel type is a mix between the truncated and cone shovels. It offers a longer shovel depth, increasing the versatility and reducing the bottom size.
Cone – this shovel configuration is suited for applications where tap-roots and dry hard digging conditions are common. These spades are taller and wider, but our compact design minimizes the overall size.

Hydraulic Legs – Dig different size root balls on the fly without manually adjusting leg sets! No leveling required – increasing quality and productivity. Available for both inside and outside frames. Can be adapted to existing spades.
Spacer Plates – This leg option is size specific – each spacer plate is intended for one specific root ball size. Simplifies the leveling process. Scrapes and packs the root ball.
Adjustable Front Legs – Leg system on the front of the spade offering 12” of adjustment. Helps level the spade but no scraping or packing capability.
