The tree is transported horizontally with the crown of the tree
facing toward the rear. This design is superior since the tree
branches will not snag on obstacles and break, but instead

The Optimal 1400 is the perfect spade for anyone interested in moving larger trees.  A 55 inch maximum rootball allows you to easily move trees up to 5½  inch caliper.  The Optimal 1400 can be operated on some larger skid steer loaders or can be adapted to work on most larger power units.  By using telescoping cylinders, the working height of the 1400 is only 69 inches and the width is 63 inches which is invaluable while maneuvering in tight nursery rows.

The Optimal 1100 is one of our most popular models.  It is capable of digging up to a 46 inch rootball and down to a 36 inch rootball.  This makes the 1100 the perfect choice for 3½ - 4½ inch caliper trees.  One of the reasons for the 1100's popularity is its ability to dig a fairly large 46 inch rootball using a smaller power unit.


The Model 1100 will run easily on a 2,500 pound lift skid-steer and can also be mounted on tractors, excavators, wheel loaders, etc.  The 1100 comes standard with electric hydraulic controls with individual blade control, universal mounting bracket, and lift pads for digging smaller rootballs.

Optimal 1100 Features:


  • Zero grease fittings
  • Compact  - digs a 4.5 inch tree with a 2500 pound lift, skid steer with no counter weight
  • Electric over hydraulic individual blade controls
  • Easily adjustable blades
  • Dual opening gates
  • Lift pads for digging smaller root balls

The Optimal 880 is the upgraded version of our old Model 850. It has been in production for over 10 years and is a tried and proven work horse in the 28-36" rootball range. Because of the compact size, load center, and weight of this machine, it can be run on a much smaller loader. Typically if you are operating one of our competitor's 28-32" spades, you can run the 880 on that same loader. This is a huge advantage if you need to step up to a 36" size. Some of the other advantages are no grease fittings and its easily adjustable blades (15 minutes or less).

Optimal 880 Features:

  • 4 blades for superior digging in hard soils
  • Dual gates - digs to right or left
  • Compact size for tight conditions
  • Superior speed
  • Optimal rootball - more roots/less soil = more trees per load
  • Reliability/German engineering and superior customer service
