SM900 Sidemount

Post Drivers Bases | The Sidemount 900

The proven, trusted, heavy duty side mount base for faster, easier fencing.

The FencePro SM900 Sidemount Base is the most popular sidemount for farmers and contractors who want to speed up day-to-day fencing with a simple, reliable post driver base. As part of the FencePro MBA modular system, the SM900 sits between your tractor and your post driver, positioning the post driver out to the side of your tractor so you can work alongside the fence line—not reversing into every post.

900mm of hydraulic side shift | Work alongside the fence line.

The SM900 delivers 900 mm of hydraulic side shift travel. It enables you to push the post driver out to the fence line while keeping the tractor running straight and parallel. Better visibility of the next post mark. This allows you to stay moving and fencing efficiently, particularly on long, repetitive fencing jobs.

4‑way movement | When paired with a Mastshift

The SM900 integrates with FencePro's modular base option of the Mastshift. Paired with a Mastshift base, give you 4-way post driver positioning:

Side shift: push out to the fence line
Mast shift: move up and down the fence line without having to get in the tractor.

That combination is a genuine time saver. Adjusting where the post driver is in relation to your post mark significantly reduces the amount of "hop in / hop out" of your tractor that you have to do and slows fencing down over a full day.

Side mounting a post driver means moving a lot of weight in and out of the fence line. The SM900 comes standard with a 240 kg counterweight to keep the unit balanced when the post driver is shifted out. The FencePro SM900 requires 1 hydraulic valve function to operate the sidemount, and is best suited to FencePro post driver models including the Farmtek, Mule, Mule V, and Ultra G2S. For larger, heavier models like the Ultra G4 and Ultra T2, the heavier-duty SM1000 is typically the better match (beefed up and fitted with a larger counterweight to suit those machines).

The FencePro SM900 post rammer sidemount base can also be custom-built to suit your existing post rammer (even if it's not a FencePro.) Reach out to the team for more info.
