A Different Approach to Cow Race Maintenance – Proven on Farm

We’re well aware this is a completely different approach to cow race maintenance, and we’d like to thank all the farmers who put it to use on their farms before Christmas.

The feedback we’ve received has been very encouraging. Despite the extremely dry conditions at the time of milling, all reports are that the races settled down nicely once the rain arrived, exactly as expected.

We’ve milled everything from:

*Rough, rocky races

*To races that were well looked after and full of fines, but badly eroded and packed down hard like concrete

In every case, the mill has done an outstanding job of making the best of what’s already there — bringing the fines back to the surface and leaving a smooth, even finish, often not unlike a sealed road.

On nearly every farm, we’ve ended up doing far more than originally planned, and on a few occasions, the entire farm. Some races needed additional fines, while others surprised us and milled up so well that we agreed to leave them as-is until next time.

The bottom line:
There is nothing else in New Zealand that comes close to this setup for quality of finish and ridiculously low cost per metre.

If you’re considering improving your cow races, give Darryll a call on 027 223 6699 We cover all of Taranaki. I’ll come out, have a look, and give you a price on the spot — along with straight-up feedback on what we can do and what you can realistically expect.

If I don’t think I can make it better, I won’t mill it.

This machine has one hell of an appetite — we’re chewing through a farm a day at the moment.
If you’ve got any races that need sorting before Christmas, we can get them done no problem.

Today we tackled the kind of race I designed this mill to deal too. I'm sure some of you will have races that look like this. Built years ago with material off the farm that has not been screened and rolled in. As time goes by the fines erode and you are left with a pretty ugly surface.
The mill does an awesome job of sorting that out and in this case we got a good result. We did not roll it or top it off as its a run off block and we just wanted to get it as good as we could for as little as possible. If it was a dairy race I'd recommend a top coat of fines rolled in.
I'm sure this will last fine with low traffic and driving the tractor down the race is no longer a bone jarring event.

We work all around Taranaki. Call Darryll on 027 223 6699.

🐄 Restore Your Farm Race – Fast, Affordable, and Built to Last 🚜

Is your cow race getting rough? Rocks showing? Potholes forming?
We can completely restore it between milking's—often with no new material needed.

✅ What Our Mill Does

*Cuts and mixes the top 100mm of the race

*Removes oversized rocks and stones

*Leaves fines on top for a smooth, durable finish

*Settles quickly because only the top layer is disturbed

*Optional light top-up if fines are low

*Edges cleaned fast with our skid steer (much quicker than a digger)

💰 The Big Benefit: COST

Our process is incredibly efficient. Most races need zero extra material, saving thousands.
A full kilometre can be restored in a single milking window.

🚜 The Result

*Smooth like a well-graded gravel road

*No more annoying rocks coming back

*Big rocks can often stay—our mill trims them off

*Ideal for new races built from on-farm quarried material

*Stronger base without screening costs

🛠️ Purpose-Built to Save You Money

We designed this machine specifically for Taranaki farm conditions. It delivers better results, faster, and for less.

Just finished replacing a bridge for Danny Hurley. 16m Double Tee bridge all concrete construction and here to last. One existing abutment was modified and reused and one replaced. A reasonable amount of earthworks done to get the crane and trucks onsite.

It is quite surprising where we can install these bridges. Over the years we have over come some pretty challenging sites.

We build all kinds of bridges so if you are thinking about replacing a bridge give us a call we would be happy to have a look and give you some pricing.

A new approach to an old problem.

Cow race maintenance can be a costly exercise. Many are built with material off the farm with over sized rock mixed in, over time they come to the surface and the only option is to keep applying more screened fines to bury them. Have you noticed that’s getting expensive?
Having spent some years dealing with this issue myself repairing races with a digger I figured there must be a better way.
It turns out there is.
We purchased the largest Tracked loader we could find and set out to build the race mill specifically designed for the job. This thing is a race eating monster! The speed at which it can mill a race and lay it back down is surprising. On the job where this photo was taken it milled and dressed up 1.3km of race in less than 3 hours. Areas we thought would require several truck loads of new metal did not need any at all. The milled race packs back down nicely. The cows no longer pick their way along the race avoiding rocks protruding through the surface as the mill removes rocks up to 300mm effortlessly and leaves behind a surface made of fines. The mill can be set to any depth up too 150mm deep allowing us to resurface a race in good condition and cut deep to remove badly rutted areas. As well as removing the larger stone it levels the surface. You will be able to run the tractor at a decent pace.
We have a digger also to make any race alterations and clean water tables etc. Before we run the mill we clean the race surface and edges to keep the race material clean. The tracked loader is considerably faster than the digger for this job.
If you are looking for a beautifully finished race for a fraction of the cost give us a call. I’ll come and have a look and give you an honest impression as to what we can do to help you.

This started out a small job, quick fix replacing the steel beams under the concrete deck. We were able to save the concrete deck and all was going well. Then the engineer got involved. Doubled the price and if there is ever a nuclear threat I'm hiding under this bridge.

New 27m Bridge site. Fair bit of work has gone into this. Getting to the end of it now. These grab buckets are awesome on rocks and trees.

This was a good little job. I like doing stuff like this.
