We build tracked chassis on the same floor where we build wheeled ones, and the question that comes in most weeks is which one a buyer should order. Two things decide it: whether the machine keeps moving when the ground turns soft, and whether it can hold a line on a slope. Both come down to ground pressure, and ground pressure is the figure most quotations quietly leave out.
Tracked machines keep working where wheels stop
On a wet site a wheeled machine pockets its tires on the first pass while tracked equipment puts the same weight across two wide rubber belts and keeps moving. That ground-pressure advantage is why tracked mini dump trucks, skid steer loaders, concrete mixers and mowers do the wet work, on construction sites after rain, on orchard floors after irrigation, and on soft topsoil that rips under a wheel load. For a contractor, the tracked machine is the one that does not cost a day every time it rains.
Ground pressure is the number to compare
A tracked chassis with rubber tracks and a steel frame spreads the machine’s weight over a contact area several times larger than four tires manage. A 500-1000kg tracked dump truck keeps a full bucket moving through mud that stops a wheeled machine carrying a similar load. Tracked machines climb better on loose surfaces as well, gravel, sand and woodchip being the obvious ones, where wheels dig in and lose bite.
| Situation | Tracked | Wheeled |
|---|---|---|
| Wet/muddy site | Keeps moving | Sinks, spins out |
| Soft topsoil / turf | Low ground pressure, no ruts | Ruts and compaction |
| Slopes | Tracks bite across the slope | Slides sideways |
| Hard standing only | Works but heavier | Lighter, simpler |
If all your work is hard-standing yards and sealed surfaces, wheels are lighter and cheaper, and we will say so. The moment mud, turf or a slope enters the job mix, tracked running gear is the difference between a machine and an ornament.
Slopes are a second tracked specialty
Remote-controlled tracked mowers such as the SDL224-55A and the SDL764-90A work inclines up to the limit the engine can climb. The tracks bite across the slope instead of sliding sideways, and the operator stays on the edge of the paddock, clear of the danger zone. Roadside banks and orchard terraces are where those machines earn their keep. The same reasoning covers tracked dump trucks on site ramps, where a loaded climb that would spin a wheeled machine is routine work for a tracked chassis.
Where tracked pays across the TorqMax range
- Mini dump trucks (SDL500/500L/500R/1000L) move spoil, concrete and materials across wet sites.
- Concrete mixers (SDL200L/360L/500L) take mixed concrete to the pour without sinking on the way.
- Remote-controlled mowers (400-900mm) handle slope work with the operator clear of the machine.
- Compact skid steer loaders (SDL330/450) cover landscaping and construction on soft ground.
Each of these machines does a job a wheeled unit also does, but the tracked version does it on the days and the terrain where the wheeled one cannot follow. That reliability is the part of the price a buyer actually feels, and it shows up in the first wet season.
What to check before buying tracked
Rubber track quality is the first thing, and specification sheets rarely tell you much about it. Ask for reinforced rubber tracks and a track system that holds tension without constant adjustment. Then ask what a replacement track costs and how fast you can get one, because tracks are the main consumable a wheeled machine never has to buy. Confirm ground clearance against your own terrain too. A tracked chassis rides lower than wheels, which suits mud and turf but needs checking on deeply rutted ground.
Buying factory-direct keeps tracks and undercarriage parts coming from the same plant that built the machine, which matters more on a tracked unit than on anything else we ship.
Frequently asked questions
Are tracked machines slower than wheeled?
On firm ground, yes. A wheeled machine wins a long straight run every time, and we tell buyers that before they order. What the tracked version gives up in top speed it takes back in traction and flotation, which is the trade that matters on wet ground, turf and inclines.
Do rubber tracks damage turf?
No, and the reason is the ground pressure figure. The weight spreads across the full belt instead of concentrating under four tires, so fine grass comes out unmarked. We ship tracked mowers to golf clubs and orchard rows for exactly that reason.
How long do rubber tracks last?
On abrasive gravel or crushed rock, expect faster wear than on turf or mud. Treat tracks as a consumable and keep spare sections on the shelf, because a mid-season failure costs more in lost working days than the track it replaces.
Which TorqMax machines come tracked?
The SDL line runs rubber-tracked chassis throughout: mini dump trucks, concrete mixers, remote-controlled mowers and compact skid steer loaders. Same model range, same factory, and the tracked version is built on the line beside the wheeled one rather than added as an option later.
