When landscape, construction or utility contractors encounter soft, muddy underfoot conditions, sloped terrain, sensitive surfaces such as turf, or tight spaces on the job site, turning a multi-terrain loader (MTL) into a mini-dozer may be the solution.
By exerting very low ground pressure, MTLs can give operators access to areas where a larger machine would not be a practical choice for moving dirt, gravel, snow and other materials or leveling the work site in finish grading applications.
Two types of blades are available. Renting these work tools can help a contractor test them on job-site conditions, to help determine the best fit for the fleet.
Angle Blades
With a bolt-on curved moldboard and a common back interface structure, angle blades can be hydraulically angled 30 degrees right or left of center. Adjustable, removable skid shoes add stability and provide depth control when operating on hard surfaces such as asphalt or concrete. Angle blades can be set at three different height positions, to accommodate specific dozing requirements or tire arrangements.
For aggressive earthmoving applications, operators can lock the blade, while for tasks such as pushing livestock waste or snow the T-handled pins can be removed to enable a lighter blade trip.
Snow kit supplements can further expand an angle blade’s capabilities. Such kits feature bolt-on guard assemblies to increase the moldboard height by 7 in. (18 cm) and to expand the angle blade contour and capacity.
High-visibility vertical edge markers, indicate blade width and moldboard orientation to machine operators. The edge markers are intended to remain flexible to temperatures above minus 40F (minus 40C).
Also available, non-metallic, reversible blade edges are designed to squeegee material without marring concrete or asphalt surfaces such as parking lots, sidewalks, driveways or airport runways.
Look for a blade with tilt and angle features. The materials should be reinforced to offer long life, even under harsh working conditions. The operator should have good visibility from the cab with the tool attached and clear views to the cutting edge.
A quality blade should have reversible cutting edges to extend the components’ wear life, while durable, wrapped hoses will help ensure leak-free operation. Two or more of the machines in the fleet should be able to operate the work tool, for added versatility and flexibility. Universal couplings should be a consideration if this kind of flexibility is desired.
Dozer Blades
Dozer blades incorporate a rugged track-type tractor variable power angle tilt blade with simultaneous tilt and angle capability for increased control and maneuverability. The center section of its bolt-on, cutting edge is reversible to extend wear life. Angled end bits, modeled after track-type tractor blades, allow flush cutting against a vertical surface when the blade is fully tilted. Adjustable, removable skid shoes enhance stability and control depth when operating on a surface such as asphalt or concrete.
Bolt-on edge segments further protect the cutting edge, lengthening the usable life of the tool. The edge is a structural component of the work tool and its blade becomes weakened if it is unprotected.
When selecting a blade, consider the application in which it will be used most often. Landscaping work typically requires more precise cuts and final grading and so the adjustability of a six-way blade is ideal for this type of work.
Angle blades are better suited for rough grading, snow removal and general earth-moving tasks. In general, the biggest work tool may not always be the most efficient, or the most advantageous for a particular customer. Contractors that will use their blades most often for grading may seek the widest blade configuration possible to extend beyond the tracks.
