Tractor requirements

You will need at least a 100 HP tractor
(ideally 120/140 HP +) to operate the AFT100

Why choose the AFT100?

Speed

Up to 5 times faster than using an excavator with a digging bucket. Do in 1 day what you would normally do in 1 week.

Resistance

Dig in extra stony conditions with the bullet chain.

Clean Trench

The sides and the bottom of the trench are left clean.

Rapid Backfilling

The twin augers leave the finely cut spoils at the sides of the trench. A simple blade on your tractor does the backfilling in no time.

Minimal Maintenance

Monthly grease, check gearbox oil, and inspect for wear. Many machines run for over 20 years with proper care.

Ease of Use

If you can operate a tractor, you can operate the AFT100. Once set up, we rarely have anyone call us back!

Cost-effectiveness

Our trencher is very affordable and is only a fraction of the cost of a self-propelled trencher.

Fast Delivery of Spare Parts

Find the part in our 3D parts book and give us a call. We generally dispatch orders within 24 hours!

What civil contractors say about the AFT100

“With a digging bucket, I would need at least a day to dig 300 metres. With the AFT100 trencher, I can do it in one hour”

Tony Elliot

Tugwell Contracting, Civil Contractor

“Impressed with the speed of the trencher and the cleanliness of the trench, the team behind were struggling to keep up to lay ducting!”

Frequently Asked Questions

Can the AFT100 go on any tractor?

The AFT100 requires a 100+ HP tractor with vario transmission or a creeper gearbox (with a minimum speed of 50 to 100 metres per hour).

Is the AFT100 easy to maintain?

Yes, other than checking the gearbox oil level, checking and adjusting the chain tension and greasing appropriately, the AFT100 is very easy to maintain.

How long will the chain last?

AFT uses chains and blades made for us in Germany. We have used the same manufacturer for over 30 years because of their quality and reliability. The wear on chains and blades depends on:

• Soil conditions (sand, clay, small rocks, etc.),
• Tractor speed,
• Depth and width of the trench.

We would be pleased to discuss in more detail your specific trenching conditions.

How will the standard chain cope with stones or clay?

The AFT100 has been designed to cope with various ground conditions, including stones (the size of footballs), heavy clay, sand and even asphalt.

What can you suggest for compacted ground or rocky soils?

We have the heavy duty AFT100 fitted with a bullet chain.

Do you have second-hand machines available?

Yes, we sometimes do. Please contact us to find out.

What is the typical speed of trenching?

Depending on soil conditions and the depth and width of the trench, anything from 75 to 150 metres per hour in normal conditions, in stony ground, slower, and in sandy conditions, faster.

Is there a safety mechanism for the gearbox?

We have an inbuilt clutch within the PTO shaft to protect against damage.

Where are the machines manufactured?

Our machines are manufactured at our factory in Sudbury, Suffolk, UK.
