Tree shears, limb shears, and brush cutters — DymaxRail builds all three specifically for railroad and transit maintenance. Sized for 5T to 36T excavators and compatible with Rail Rider hi-rail systems.
Cut, grab, and stack trees up to 21″ diameter without leaving the cab. Integrated grapples hold the trunk through the cut so the operator controls where it goes. Available with optional rotation for 5T to 36T excavators and backhoe loaders.
Strip overgrown brush back to the ballast shoulder in a single pass. The 60″ cutting head mulches brush and small trees up to 8″ diameter. 750-lb flywheel, three AR400 blades. Available for 20-30T excavators.
Reach limbs over catenary, along signal lines, and under bridges — all from the boom. 180° hydraulic rotation adjusts the cutting angle without repositioning the machine. Available in 8″ to 24″ capacities for excavators, backhoe loaders, and grapple trucks.
Rail corridors present three distinct vegetation problems, and each one calls for a different cutting tool.
Many MOW vegetation programs deploy two or three of these tools, often on the same excavator fleet equipped with DymaxRail Rail Rider hi-rail systems.

Specifications are subject to change without notice.
| Yes. Tree shears mount to the boom using standard pin-on or coupler interfaces — the same way they’d mount to any excavator. Pair the excavator with a detachable hi-rail system like the DymaxRail Rail Rider and the machine travels on rail to the work site, clears vegetation from the track, and returns — no dedicated vegetation machine needed. DymaxRail builds both the hi-rail systems and the cutting attachments, so fitment and hydraulic compatibility are engineered together. Contact DymaxRail for a machine-specific recommendation. |
| Match the shear to the diameter of the trees you’re cutting and the size of your excavator. DymaxRail HPX tree shears cover five capacities: 8″ (5–6T excavators), 10″ (8–14T), 14″ (12–20T), 16″ (16–23T), and 21″ (25–36T). For mixed vegetation that includes brush alongside larger trees, many rail crews pair a tree shear with a VortexMax brush cutter on the same machine or a second machine in the same possession. Contact DymaxRail for sizing guidance based on your machine and corridor conditions. |
| Each tool handles a different tier of the vegetation problem. Tree shears cut, grab, and stack full-diameter trees (8″–21″). Rotating limb shears reach overhanging limbs in tight clearance zones — canopy clearing, along signal lines, under bridges — with 180° hydraulic rotation. Brush cutters (VortexMax) mulch undergrowth, saplings, and brush up to 8″ across a 60″ cutting width. Most rail vegetation programs use at least two of the three. Contact DymaxRail to match a lineup to your corridor conditions. |
| All DymaxRail HPX tree shears use AR400 abrasion-resistant cutting knives. Blade thickness scales with shear size: 1/2″ on the HPX8, 5/8″ on the HPX10, 3/4″ on the HPX14 and HPX16, and 1.0″ to 1.25″ on the HPX21. Blades are replaceable in the field. Contact DymaxRail for replacement blade pricing and lead times. |
| DymaxRail HPX tree shears are available with 60°, 97°, or 180° rotation, depending on model and excavator size. Rotation lets operators adjust the cutting angle without repositioning the machine — critical in rail work where track time is limited. Rotation models require a second hydraulic circuit; if your machine has only one auxiliary circuit, DymaxRail can quote an electro-hydraulic diverter valve solution. Contact DymaxRail with your machine make and model for a compatible configuration. |
