Montana Post Drivers

A hydraulic fence post driver sets wood posts, T-posts, guard rail, and sign posts straight into the ground without pre-drilling, concrete, or a hole to backfill, which turns a two-person day into one operator working from the seat. This collection covers drivers for skid steers, excavators, mini loaders, and tractors, along with the tooling that goes with them: flat, domed, oversized, and conical point tools matched to post type. Drive style is the decision that matters. Vibratory units set posts quickly in soft to moderate ground, while impact drivers deliver more energy per blow for hard, rocky, or frozen conditions.

Frequently Asked Questions
What machines can run these post drivers?


The collection covers drivers built for skid steers, excavators, mini skid steers, and tractors, so the same fence line can be worked from whichever machine suits the terrain. Each version is built around a different mount and hydraulic setup rather than being interchangeable. Tell us which machine you run and we will point you to the matching driver.


Which driving tool should I use?


Tool choice follows post type. Flat tools suit T-posts and square stock where the top will not deform. Domed tools cup a round wood post and keep the top from
mushrooming as it drives. Oversized domed tools cover larger corner and brace posts. Conical points are for driving pipe and ground rods. Most operators keep two or three and swap by job.

How much hydraulic flow does a post driver need?


Most run on standard auxiliary flow in the range a full-size skid steer provides, so a high flow package is generally not required. Compact and mini versions are built for the lower output those machines supply. What matters is matching the driver to the machine rather than assuming, since running below the rated flow costs you energy per blow and slows the work.


Will a post driver work in rocky ground?


Impact drivers handle hard, frozen, and rocky conditions better than vibratory units because they deliver more energy per blow. But solid rock or caliche will mushroom post tops and stress the attachment rather than driving through. At that point an auger with a rock bit is the right tool. Many fencing contractors keep both and choose by the ground.


Can these drivers pull posts as well?


Several models accept a post puller chain or attachment that extracts old or misdriven posts using the same tool. That is genuinely useful on fence replacement work, where you are pulling about as many posts as you set. Pullers are usually specified at order time rather than added later, so check the listing or ask before you buy.
