The goal in building these 3rd generation truck spades was to design units that could not only last but be compact enough to easily get in and out of tasks easily. Our focus was not on the cost effective method of building a unit but rather the best way to design a unit that will meet all conditions all the time. At Dutchman, we are forever striving to build a better, more refined tree spade. Common issues such as tall towers, small frames and weak blades all had to be addressed. Most of these concerns were shared by many, if not all, owner-operators within the truck spade moving industry. State-of-the-art technology, computerized sketches, and stress analysis all played a part in building a sleek, compact, reliable unit that makes for a solid, sound investment.
We were able to develop methods to cold form blades making them stronger than the original AR450 material used. We designed new methods and placement for support ribs, and added scraper plates to keep the soil from sticking. This now allows the user to wire basket trees without any obstruction on the outside of the blades.
After the blades were strengthened, we focused our attention on shortening the overall height of the spade itself. Many have complained before that their conventional spades cannot get under the canopy of the tree. In order to combat this issue, we had to first redesign the conventional way a cylinder operates. The end result was a new patented, multistage cylinder that does not have any oil displacement issues or side load concerns. The speed is consistent through out its stroke and has the power to get the blades in the ground. These cylinders now enable us to build much shorter towers then other brands.
We also wanted to address concerns on how the blade is supported on the tower. Rather than guiding the blades on narrow track like the competition, we use the face of the tower itself: the surface area of the slider is many times greater than small interior rails. The interior support ribs are also used to mount the blades to the slider housing. The width of these ribs is more than double the competition, holding the blade at a much wider position. The blades are pulled down the tower by the trunnion mounted cylinder in the center of the slider box; this position is the most favourable as it is directly in line with the the tracking system.
Lastly, we wanted to address the constant concern of too little operating space within the frame of the spade. We created a completely circular frame that has plenty of room inside to accommodate wide low branching trees. All frames are structurally much stronger than frames that are pieced together using hollow tubes and flat bar. The gates were made taller and have replaceable hardened steel bushings. Finally, the frame has a hydraulic locking mechanism to ensure a stable connection when digging.
Combined, all of these features and innovations make the Dutchman Truck Spade the strongest and easiest to use on the market.
Dutchmans straight-blade 50” truck mount is ideal for digging up to 5” trees. The overall weight of the unit is light enough to go on a 19,000GVW, single-axle truck. Minimum cab-to-axle needs to be 84 inches. Built with the same quality and durability you have come to know from Dutchman.
Dutchman Industries' optional “Wobble-Tail and Extension” is an ideal option for limiting the amount of reversing needed when lining up a tree. The “Wobble-Tail” allows you to shift the entire digging head left and right and the Extension allows you to throw the unit up to 10 inches backward. This allows the operator to manipulate the spade while keeping the truck stationary. Ideal for single operators. This option is available for the Dutchman model 48”, 55”, 60” and 66” Truck Spades.
Dutchman Industries also offers dirt covers for all sizes of Dutchman Truck Spades and even the competition's truck spades. Dirt Covers assure the least amount of soil is lost while in transit. Two fabricated metal plates with a horseshoe cutout allow the operator to easily center the tree trunk inside the cover.
Dutchman Industries offers Spade Tarps to prevent soil loss through the spade while in transit. While available for Dutchman Truck Spades, Spade Tarps are also available for other makes of truck spade that may develop large blade-gap issues over time.
