Rhino DB150 Boom Mower

Description

The Rhino DB150 boom mower reaches ditches, pond banks, and levees that standard mowers can’t touch. Its hydraulic boom extends 158 inches from the tractor’s centerline, so operators clear steep banks without leaving the seat. Because the system runs on hydraulics instead of belts and chains, maintenance stays minimal even under heavy use. The 60-inch cutting head pairs with updraft blades for a clean, consistent cut. In addition, the head swings through 175 degrees of arc, covering slopes most tractors can’t reach. That range also handles overhead trimming along fence lines and tree limbs. Operators count on the Rhino DB150 boom mower for tough right-of-way work.

A stationary 60-gallon oil reservoir doubles as a mainframe counterweight, so it never swings into traffic during operation. The reservoir also keeps hydraulic fluid cooler, which extends pump and motor life. Meanwhile, a CAT 4 driveline delivers power through a fully shielded connection for safer operation. The heavy-duty boom arm uses a specialized steel alloy that resists bending under constant load. Similarly, the frame-mounted hydraulic motor keeps weight off the deck, cutting downtime and repair costs. For transport, the DB150 retracts to a width of 119 inches, so it clears narrow gates with ease. Overall, the Rhino DB150 boom mower gives crews a durable, low-maintenance mowing solution.

Features

Reach & Mowing Performance

Extending Hydraulic Boom
Reaches 158″ from the tractor’s centerline, clearing pond banks, levees, and ditches most mowers can’t reach.

Wide Head Movement
Head swings 85° up and 90° down for a full 175° range, handling slopes and overhead trimming.

Updraft Blades
1/2″ x 4″ updraft blades spin at 16,870 FPM for a clean, consistent cut.

Hydraulic System & Reliability

Stationary Oil Reservoir
The 60-gallon reservoir doubles as a mainframe counterweight, so it never swings into traffic.

Cooler Running System
Larger reservoir capacity keeps hydraulic fluid cooler, extending pump and motor life.

Heavy-Duty Ball Valve
Separates the reservoir from the pump, motor, and hoses to reduce oil loss during maintenance.

Frame, Hitch & Transport

CAT 4 Driveline
Fully shielded driveline delivers power safely and mounts easily to the tractor.

Reinforced Boom Arm
Special steel alloy construction adds strength and rigidity under constant load.

Narrow Transport Width
Retracts to 119″ for easy transport through narrow gates and roads, with a locking arm and support stand for safe storage.
