True, CTL sales have soared, but depending on the manufacturer and the size category, skid steer sales have at least held steady and, in many cases, have slightly increased.
There are two important factors to keep in mind regarding this shift in sales volume that seems to put skid steers at a disadvantage. First, CTLs are still relatively new. As more customers are discovering the advantages of tracks in certain applications, more tracked units are being sold.
“After customers with legacy machines replace their skid steer loaders with compact track loaders, the rapid growth of compact track loader adoption over skid steers will likely start levelling out,” says Kevin Scotese, Volvo skid steer product manager. He says that since the service life of a skid steer loader is 5,000 hours, many legacy machines will be due for replacement soon, “adding to the probability that market share erosion will level off after those machines are replaced.”
The second factor is that the shift in sales volume is almost exclusively a North American market phenomenon. Globally, skid steer sales far eclipse compact track loader sales, says Gregg Zupancic, product marketing manager, John Deere. “Outside of North America, CTL sales are spotty and number around 2,000 units per year, while skid steers are in the 20,000- to 30,000- unit range.”
Zupancic says it’s understandable that CTLs are stealing the limelight; Deere’s sales in 2016 were about 60 percent CTLs and 40 percent skid steer loaders. “But the trend line for skid steer sales over the past five years is up.”
Another bit of conventional wisdom is that skid steers preserve their market share in part because they’re faster than CTLs. Marketwide, that’s true. Skid steers typically can travel 10 to 12 mph, while the top speed of CTLs is 7 to 10 mph. But not so fast, say some OEMs. Buck Storlie, testing and reliability leader with ASV, points out the company makes compact track loaders with travel speeds of 11 mph.
Some OEMs suggest that customers ask themselves, “How important is speed anyway?” Certain applications, such as sweeping and snow removal, favor faster speeds. Randy Tinley, product manager of skid steer and compact track loaders with JCB, says scraping operations are also better at higher speeds, but those are mostly found in ag (mucking out barns, for example) and less often in construction.
Lift-and-carry and traveling from site to site also emphasize speed. But for a large percentage of tasks, including loading and running attachments where the machine is stationary, top travel speed is not a factor. Examples of static operations with attachments include concrete pumps, stump grinders, chippers and augers, says Eric Dahl, product manager, Bobcat.
Now that we’ve killed the two most common myths, what truths remain?
Where skid steers lead
First on the list of great truths about skid steers is that they’re preferred for work on hard surfaces. And, yes, they’re faster. “And there are applications where the work may take place in the dirt, but the machine travels over pavement to get from one part of the job to another,” says Brent Coffey, loader product manager with Wacker Neuson. “The skid steer is the machine that covers the distance the quickest and handles both situations, work and travel, with equal ease.”
With the right tires, skid steers are also the machine of choice in places where debris can damage equipment, such as demolition, recycling and waste handling. Brian Rabe, regional training manager for Manitou Americas (parent company of Gehl and Mustang), says skid steers have better shock absorption. “In applications with sharp bumps and in rocky conditions, skid steers provide better operator comfort than would be had in a compact track loader.”
They’re also preferred for snow removal, whether using a snowplow, snow blower or snow pusher, because they provide greater traction. Snow removal is relevant to, at most, half of all skid steer customers, and then only for a certain portion of the year. But to those customers, a skid steer’s snow capabilities means it can generate additional revenue instead of sitting idle for months.
With their amazing maneuverability – such as being able to counter-rotate and execute spin turns – skid steers shine in tight jobsites. “The skid steer is the original poster child for jobsite mobility and remains dominant in that role,” says Hugo Chang, wheel loader and compact product manager at LiuGong.
This maneuverability results from the weight bias on a skid steer, which is typically around 30/70 front/rear unloaded; the reverse ratio is true with a full bucket. Dahl says this imbalance means one set of wheels, the front or rear, is bearing less weight than the other set at any time. This makes tight turns easier, reduces tire scrub and minimizes surface damage.
Tracks on a CTL can be counter-rotated, but it’s not a good idea. “To maximize the service life of tracks and undercarriage components, a CTL should be operated like a dozer with long, sweeping turns,” says Tharen Peterson, brand marketing manager, New Holland Construction.
Maximum maneuverability is also essential in applications that require precise positioning of attachments, such as breakers and sweepers, notes Dahl.
George MacIntyre, global product portfolio manager, light equipment, Case Construction, says industry data reveals several areas where skid steers are preferred over CTLs by a margin of 3-to-1. Among them are scrap, waste, recycling, industrial material handling, and mine and quarry. “Demolition, agriculture, and state and municipal markets also use more skid steers, but by a smaller margin,” he says.
MacIntyre adds that skid steers are better for clearing, cleaning and back-dragging. Operators tend to put a lot of downforce on the attachment – whether broom, bucket or blade – shifting much of the weight to the rear of the machine. Tracks want to be evenly loaded; wheels are more tolerant of this type of imbalance.
Coffey says some attachments still work best on a compact track loader, especially those requiring a heavy machine with superior stability, such as tree spades.
“Anything done on wheels is more easily done on tracks,” says Storlie. That comment from ASV’s testing and reliability leader, is no surprise; ASV has a long, proud history with compact track loaders. But it’s not just machine ability that matters to customers; it’s also profitability. “If the same job can be done by either a CTL or skid steer in the same amount of time,” Storlie explains, “the skid steer will be cheaper.”
When comparing track and wheeled machines with similar engine and hydraulic specs, the CTL will cost up to 20 percent more. Skid steers also use less fuel and require significantly less maintenance. Radial-lift skid steers, with their simpler lift mechanisms, maximize the differential in both initial and ongoing costs. “Compact track loaders, on average, cost 5 to 10 percent more to operate and maintain,” says Scotese.
A key component in the O&O cost difference is the expense of maintaining an undercarriage and replacing tracks. “Tracks remain highly engineered,” says Chang, “while skid steer tires have almost become commoditized and have a well-established supply chain.”
Because of their lighter weight, skid steers can reduce transport costs, says Scotese. The required ratings of the trailers and tow vehicles used for transport may be lower, and the combined rating may make a CDL unnecessary.
Peterson says, though, that as skid steers get larger and more expensive, the difference in initial investment between the biggest skid steer models and some compact track loaders is decreasing.
Narrowing the gap
Even in areas where CTLs have clear advantages, owners of skid steers can take steps to narrow the performance gap. Over-the-tire tracks (OTTs) can provide many of the benefits of a dedicated track machine and can yield lower ground pressure for a skid steer than a comparable CTL, says Dahl. That’s because the skid steer weighs less than the CTL. The weight difference is enough that the ground-pressure advantage remains in place despite the difference in track-on-ground surface area between the two machines.
Dahl says customers who need tracks all the time have switched from skid steers to compact track loaders, greatly reducing the demand for over-the-tire tracks. The availability of CTLs from rental houses has also cut into demand by making them readily available to customers who need them only occasionally. But for customers who need tracks seasonally, OTTs are a cost-effective solution.
But Zupancic warns there are potential issues with over-the-tire tracks. They can collect rocks, scraps of lumber and other debris that may break tire beads and may even break a chain. The machine can walk out of its tracks on counter-rotation, especially with rubber tracks. Steel tracks can cut tire sidewalls.
Jorge De Hoyos, Kubota senior product manager of skid steers and compact track loaders, says installing tracks over solid and semi-solid tires can overstress parts of the skid steer. That’s because these types of tires may not offer enough flex, and the weight and shock load of the tracks are passed directly to the chain tank walls of the undercarriage.
Storlie notes that all ASV skid steers are designed to accept over-the-tire tracks. Fender clearance, wheel bearings and hub design accommodate the additional size and weight of add-on tracks. ASV acquired Loegering in 2004 and offers Loegering tracks.
Tinley says that while track options are mostly limited to width, tires offer many options. While various widths are also available with tires, tread patterns are a more important part of the package, as are solid, semi-solid and pneumatic options.
Tire chains are also available. While chains don’t improve flotation, they add traction and weight and can improve performance in sloppy conditions.
Bolt-on counterweights also enhance SSL performance, and the same counterweight has a bigger effect on the capacity of a skid steer than a CTL. This is because the same weight is a higher percentage of the machine’s own weight. Zupancic points out that solid and semi-solid tires also add weight; the elongated holes in semi-solid tires provide some cushioning.
Ultimately, the performance level of a skid steer comes down to operator skill, says MacIntyre. “Operators need to maintain situational awareness of jobsite conditions and plan ahead. They need to know how to get un-stuck. They should read the owner’s manual, which will give guidance on managing hills, slopes and other obstacles.”
Even so, says Peterson, the advantages CTLs offer are unique to them and cannot be fully replicated on a skid steer, regardless of the skill of the operator.
