PDX-1000 Post Driver Attachment

PDX-1000 Skid Steer Post Driver Attachment

Drive posts into almost any terrain with the Eterra PDX-1000 Skid Steer Post Driver. It's built for fencing contractors, and Eterra calls it the top of the line in compact equipment post driving. A nitrogen-charged power cell, activated by your machine's hydraulics, delivers a solid 1,000 ft-lbs of energy and 32,000 lbs of impact force with every strike, driving posts into almost any ground condition.

The power cell sits in a heavy-duty housing on isolators that reduce vibration to both the machine and the operator, keeping operation smooth. The driver body sits two feet closer to the machine than competing models, which improves down force, maneuverability, and visibility. The post guide housing encloses the bottom of the driver head, making it easy to keep the driver on the post.

The PDX-1000 comes standard with a post guide housing array for 2", 4", 6", and 8" posts, which is removable for posts over 9". You also get a choice of domed or flat driver head tools and a 5 ft. breaker spike, all made from high tensile strength tool steel, so it's built to stand up to constant use on your skid steer. An optional 15° hydraulic tilt lets you position posts easily on varied terrain.

Key Features

• Nitrogen-charged power cell: 1,000 ft-lbs of energy and 32,000 lbs of impact force per strike
• Vibration isolation: the power cell is isolated in a heavy-duty housing for rapid, powerful actuation with minimal vibration
• Closer to the machine: the driver body sits two feet closer to the machine than competing models, improving down force, maneuverability, and visibility
• Enclosed post guide housing: keeps the driver on the post, with guides for 2", 4", 6", and 8" posts, removable for posts over 9"
• Two driver head options: domed or flat driver heads made of 4140 steel
• 5 ft. breaker spike: pre-punch post locations in rocky or hard-packed ground
• Optional 15° tilt: a hydraulically controlled tilt mechanism adjusts 15° left and right for hilly terrain (tilt versions only)
• Plumb chains included: visual feedback for accurate, plumb driving
• Flat face couplers included: standard flat face couplers and average-length hoses come with the unit
• Ready to work: designed to arrive ready to operate with a minimal amount of assembly

Specifications

Driver Head Options

• Domed Driver Head: 8" outside diameter, with a lip that holds posts centered while driving. Ideal for flat or tapered posts in the 4–7" range, and it can be used without eyelets.
• Flat Driver Head & Eyelets: 9" diameter for flat posts up to 9". Eyelets are provided in 2.5", 4.5", 6.5", and 8.5" sizes. Choose an eyelet just larger than your post, or modify one for guard rails, custom Theta posts for solar applications, and other shapes.

Maintenance at a Glance

• Lubricate the main shaft with two shots of Schaeffer SynForce® Strike Chisel Paste every 4 hours of use. Don't use regular grease on the main shaft.
• Tilt models have an additional grease point on the rotating tilt base, which takes standard grease.
• Check attachment bolts weekly. It's a high-impact tool with constant vibration, and loose bolts can fail.
• Check and adjust the nitrogen charge to 250 PSI (17 bar): yearly for light use, every 6 months for moderate use, and every 3 months for daily use. A charge kit is supplied with the post driver; you provide the nitrogen tank.
• Low driving power? Checking the gas pressure is the first troubleshooting step.

Frequently Asked Questions

Q: How powerful is the PDX-1000?
A: Its nitrogen-charged power cell delivers 1,000 ft-lbs of energy and 32,000 lbs of impact force per strike, enough to drive posts into almost any ground condition.

Q: What hydraulic flow and pressure does it need?
A: 13–21 GPM, with an operating pressure of 1,700 PSI and a minimum of 1,400 PSI.

Q: What size skid steer do I need?
A: Your machine needs a minimum lift capacity of 1,500 lbs. The PDX-1000 weighs 1,186–1,656 lbs depending on options. Contact us before ordering and we'll help confirm it's a match for your machine.

Q: What post sizes can it drive?
A: Up to 8" diameter with the domed driver head and up to 9" with the flat driver head. The standard post guide housing handles 2", 4", 6", and 8" posts and can be removed for posts over 9".

Q: Which driver head should I choose?
A: The domed head is ideal for round or tapered posts in the 4–7" range and holds them centered while driving. The flat head handles flat posts up to 9" and works with eyelets sized just larger than your post.

Q: Is the tilt function standard?
A: Tilt is available on tilt-equipped versions. It adjusts 15° left and right using hydraulic valves, which helps when you're driving posts on hilly terrain.

Q: What is the breaker spike for?
A: You can use the 5 ft. breaker spike to pre-punch post locations in rocky or hard-packed ground. That lets you pre-stand many posts so they can be driven without a helper holding each one to start.

Q: Can I drive any type of post?
A: Use strong, solid posts. Because of the driver's power, weak or old posts can shatter.

Q: Does it come with couplers and hoses?
A: Yes. Standard flat face couplers and average-length hoses are included. Non-standard couplers aren't supplied and should be sourced locally to match your machine. Hose routing varies by machine, so you may need a 45° or 90° fitting for your setup.

Q: What electrical connection does the tilt option need?
A: The solenoid-controlled tilt option supports 14-pin, 8-pin, and 7-pin Bobcat electrical control, as well as standard switch control. Make sure you have the correct adapter for your machine.

Q: How often does the nitrogen need to be recharged?
A: Yearly for light users, every 6 months for moderate use, and every 3 months for daily use. Charge it to 250 PSI (17 bar) using the included charge kit and your own nitrogen tank.

Q: Is there an excavator version?
A: Yes. Eterra also offers the PDX-1000 post driver for excavators.

Q: Where can I find the spec sheet and manual?
A: Download the PDX-1000 spec sheet (PDF) or download the PDX-1000 operator's manual (PDF).
