Since first introduced more than half a century ago, compact ride-on trenchers have become nearly indispensable to equipment fleets. Known primarily for their ability to squeeze into tight spaces, compact ride-on trenchers are well-suited for a variety of projects. Jobs that used to involve a spade and lots of sweat can now be completed in a fraction of the time, thanks to the reliable and maneuverable compact trencher.
“It’s hard now to imagine a world without compact trenchers,” says Jon Kuyers, senior global product manager at Vermeer. “They are efficient, labor-saving machines. It would be difficult to accurately estimate the cumulative amount of time, labor and expense these small workhorses have saved, but it certainly can be said the impact has been significant.”
Manufacturers have responded to customer feedback by developing models that are not only compact in frame, but pack enough power to complete an array of jobs in varying soil conditions. The equipment’s small size also contributes to its ability to keep ground pressure low and minimize surface disturbance.
Categorizing compact trenchers
Although a compact ride-on trencher category has not officially been defined, the machines are most often classified by tractor horsepower and width of frame. Machine weight also plays a role, but industry experts concur that what matters more than total weight is the impact, or “footprint,” the machines make on a jobsite.
“There are several options for controlling footprint,” Kuyers says. “Trenchers outfitted with tracks exert the least amount of pressure, but there are also options for machines with tires. The goal is to cause as little damage as possible to turf and sensitive landscapes.”
Although opinions may vary, most manufacturers would likely concur that as a category, compact ride-on trenchers would be defined as tractors under 50 horsepower (37 kW) less than 72 inches (182.9 cm) wide and generally under 10,000 pounds (4,535.9 kg) total machine weight (including attachment). Trenching widths and depths for compact ride-on trenchers most commonly range from 2 to 12 inches (5.1 – 30.5 cm) wide, to a maximum of 5 feet (1.5 cm) in depth — ideally suited for shallow- to medium-depth installations.
These machines are more portable, and, with the use of different attachments, often more versatile than their larger conventional trencher counterparts. Their overall weight also makes impact to sensitive jobsites less destructive.
Performance in a small footprint
The ability to maneuver effectively in and around tight spaces is one of the most beneficial features of compact trenchers. They can fit through most gates and into tight spots, making them ideal for jobs in crowded urban or residential areas.
Engineers consider weight, size, steering angles, turning radius and overall ease of operation when designing compact trencher models. Maintenance and operator safety are also major factors.
Hydrostatic drive is one of the most significant features offered by a compact trencher — it allows operators to maximize production efficiency with minimal operator effort. Hydrostatic-driven machines also require less maintenance due to fewer moving parts.
“The trend for our customers is to go with hydrostatic,” Kuyers says. “There is less maintenance, and hydrostatic has the ability to improve productivity. While these machines are very efficient, it’s important to remember that the performance of all trenching units, regardless of size and horsepower, will depend on soil type and the amount of debris encountered.”
Compact trenchers developed in recent years also place an emphasis on safety. Features such as operator presence systems which automatically shut down trencher and ground drives when the operator leaves the seat, and advances in comfort have helped lessen operator fatigue and increased productivity. Padded seats that can be adjusted for height and position relative to steering and adjustable armrests help reduce tension and back stress.
Attachments abound
A big advantage for compact ride-on trenchers is that they can be outfitted with multiple attachments, making them ideal for contractors who take on a variety of tasks. In addition to conventional chain-and-boom trenching attachments, many models can be easily adapted with a vibratory plow, auger/boring attachment, backhoe, reel carriers and trench backfill blade attachment.
