The Blue Diamond® Trencher excels in durability and productivity over competitors. Its extended auger prevents trench collapse, while the self-adjusting crumber ensures a clean finish. Various chain options and widths are available, and an adjustable foot maintains consistent trench depth. Featuring an Eaton drive motor and planetary drive for high torque, it's designed for contractors who prioritize reliability.

All Blue Diamond attachments carry a 12-month warranty against defects in material or workmanship.

Refer to the manufacturer's manual for full warranty details.

The following warranty applies to the specific components or attachment types below:

Hose, Couplers, Hose Routing, and Connections:
BDA supplies attachments with hoses that are a universal size for most machines but because the configuration varies by manufacturer, we cannot guarantee that the hose length will be correct on every machine or for every routing.

It is the responsibility of the end user to adjust the length of the hoses to fit their specific machine. It is also the responsibility of the end user to ensure the hose routing is such that the hoses will not become tangled, caught, pinched, crushed, or run over during operation.
It is the end user’s responsibility to ensure that the hose routing clears pinch points and allows the attachment to move properly.
BDA will not cover hose or coupler damage due to poor hose routing. Hose extenders and hose keepers are available at additional cost to accommodate machines with unique requirements.

BDA supplies most attachments with standard size quick couplers while other attachments have the couplers sold separately. The coupler configuration on machines can vary by manufacturer so we cannot guarantee that the standard coupler will be correct on every application. We are willing to change couplers before the attachment leaves the facility if it is noted on the order. For applications where couplers are sold separately, they will be installed before the attachment leaves the facility if it is noted on the order. BDA is not responsible for coupler sizes after the attachment has left the facility unless a different configuration was specified at the time of order.

Hydraulic Motors:
Do not disassemble any hydraulic motor. Disassembly of the motor voids the motor warranty.
BDA products with hydraulic motors have a one (1) year warranty on parts and labor. In the event of a motor issue, a warranty claim must be submitted and reviewed by an authorized BDA representative. BDA cannot return disassembled motors to the motor manufacturer. Do not disassemble the motor. Hydraulic motors under warranty will be exchanged if found to be defective. There are no user serviceable internal parts available for a motor that is covered under warranty.

Cylinders:
Defective cylinders are covered for one (1) year. Disassembly of the cylinder will void the cylinder warranty. In any event of a cylinder failure, submit a warranty claim prior to disassembly or repair. Cylinders under warranty get exchanged if found to be defective. For a cylinder claim to be granted, the defective cylinder must be returned to BDA.

Augers:
Auger units have a one (1) year warranty on mount and mount components. A Lifetime warranty for shaft pull-out; a five (5) year planetary drive warranty; and a three (3) year hydraulic motor warranty.

Breakers:
Hydraulic Breaker Hammers have a three (3) year warranty policy: one (1) year on parts and labor, and the rest on parts only. Dis-assembly of the breaker in any way may void the warranty. Please contact BDA for instructions and authorization before taking apart, to verify warranty. Bent and broken tools are not covered by warranty; see ground engaging components note below.

Brush Cutters:
Brush Cutters have a one (1) year warranty on parts and labor. Dis-assembly of the cutter in any way, including the blade carrier, housing components, and/or motor, may void the warranty. Please contact BDA for instructions and authorization before taking apart to verify warranty.

Grapples:
Grapples have a one (1) year warranty. Faulty cylinders are covered by warranty. Do not disassemble the faulty cylinder; it will be replaced outright if determined it is defective. Bent tines and/or bent hydraulic cylinders are not covered nor implied by warranty.

Hay Spears:
Hay Spears have a one (1) year warranty, with a two (2) year warranty on the tines against breakage from normal use. Warranty does not cover tines that have been used to prod or turn bales without being fully engaged in the bale. This will cause bending.

Pallet Forks:
BDA Pallet Forks have a one (1) year warranty. If the forks are used in an application where the weight that is lifted exceeds the fork rating, all warranty coverage will be voided. Damage due to prying or pushing (side load) is not covered by warranty. Lifting items such as boulders puts excessive force outward on the tines and may cause damage and or injury. The fork capacity rating is when the weight of the load is X” from the rear of the tine.

Stump Grinders:
Stump Grinders have a one (1) year warranty on parts and labor. Dis-assembly of the grinder in any way, including housing components, and/or motor, may void the warranty. Please contact BDA for instructions and authorization before taking apart, to verify warranty. Broken teeth are not covered by warranty; see ground engaging components note below.

Vibratory Rollers:
Vibratory Rollers have a two (2) year warranty that covers any issues with materials or workmanship. No warranty coverage on wear parts like hoses or shock mounts.
