Fertiliser & Muck Spreaders from Scot Agri

Scot Agri is an authorised dealer for KRM fertiliser spreaders and Ktwo muck spreaders.

On the fertiliser side, we supply the full KRM range: the M Range and L Range mounted spreaders (including the L15W, a precision row-crop version built for orchards, vineyards and hop yards) and the K Range trailed spreaders, from compact single-axle models up to high-capacity bogie machines for bigger acreages and contracting work.

On the muck spreading side, we supply the full Ktwo range: the ECO and DUO vertical beater spreaders for general farm work, the EVO vertical beater range for the most demanding conditions and the largest loads, and the BIO horizontal beater range, which includes high-capacity tandem-axle models.

Alongside new and used machine sales, we hold genuine KRM and Ktwo parts and provide manufacturer-standard servicing, including field servicing, so your spreader is looked after through every application season. Our team can also talk you through trade-ins if you're upgrading an existing machine.

A fertiliser spreader broadcasts a dry, granular or powdered product, such as fertiliser or lime, across a wide working width using one or more spinning discs. A muck spreader handles bulkier, heavier organic material, such as farmyard manure, digestate or compost, using rotating beaters to break it up and fling it out behind the machine.

Because of what they're built to handle, the two are specified differently. Fertiliser spreaders, like KRM's K, M and L ranges, are rated by working width (from 10m on the smallest L Range model up to 42m on the M Range) and hopper capacity in litres, since the priority is an even, accurate application rate across a wide area. Muck spreaders, like Ktwo's ECO, DUO, EVO and BIO ranges, are rated by design capacity in kilograms and load volume in cubic metres, since the priority is moving and breaking up a heavy, bulky load consistently without blocking.

In practice, a fertiliser spreader suits arable top dressing, lime application and precision crop nutrition, while a muck spreader suits managing organic matter and manure on livestock and mixed farms, or clearing out sheds and yards. Some farms use both as part of the same nutrient management plan: a muck spreader to apply organic matter, and a fertiliser spreader to top up with mineral fertiliser or lime where it's needed.

KRM's fertiliser spreaders are split across three ranges, covering trailed and mounted machines from precision, low-rate work up to high-capacity trailed spreading.

The K Range is KRM's trailed spreader line, spreading lime and fertiliser across working widths of 12 to 36 metres. It runs from the 3.50m³ K45 through to the 15.60m³ K165 (18.95m³ with the hopper extension), with single-axle models up to the K105 and bogie models from the K105 Bogie upwards. It suits bigger acreages and contracting work where trailed capacity and a wide working width matter most.

The M Range is KRM's general-purpose mounted spreader, with working widths of 12 to 42 metres and capacities from 1,250 to 5,550 litres across models from the M35 base up to the M60W plus. It's built for everyday fertiliser spreading on arable and mixed farms, with full ISOBUS compatibility, automatic calibration and a weighing system for accurate rate control.

The L Range is KRM's smaller, more precise mounted spreader, with working widths of 10 to 24 metres and capacities from 500 to 2,050 litres. It suits lower application rates, part fields and specialist crops, and includes the L15W, a 2-row version with adjustable row spacing from 2 to 8 metres, purpose-built for orchards, vineyards and hop yards.

Ktwo's muck spreaders are split across four ranges, stepping up in capacity and power from general farm work through to the most demanding contracting conditions.

The ECO Range is Ktwo's entry point into vertical beater spreading, with design capacities from 5,000 to 7,500kg (7.8 to 10.8m³ heaped) and power requirements from 75 to 95hp. It's built for a fine, accurate spread on general farm work, and is a cost-effective starting point for farms moving into their own muck spreading.

The DUO Range steps up in capacity and power, with design capacities from 6,000 to 14,000kg (9.8 to 23.2m³ heaped) across six model sizes and power requirements from 85 to 160hp. A tapered body and faster rotor speed give a wider, finer spread, suiting farms with more ground to cover or heavier muck volumes.

The EVO Range is Ktwo's vertical beater range for the most demanding conditions, with design capacities from 14,000 to 26,000kg (21.5 to 29.7m³ heaped), power requirements from 135 to 200hp, and tandem-axle options on the largest models. Market-leading running gear makes it suited to big loads and heavy contracting work.

The BIO Range uses twin horizontal beaters behind a hydraulic opening canopy instead of vertical beaters, covering the same 14,000 to 26,000kg design capacity range as EVO but giving a wide, consistent spread of up to 32 metres across all types of manure and by-product, with less risk of funnelling or bridging in the load.

Yes. ISOBUS compatibility is available across the KRM range, either fitted as standard or available as an upgrade, depending on the model.

ISOBUS (ISO 11783) is an international standard that lets a single in-cab terminal communicate with and control implements from different manufacturers through one connection, rather than needing a separate control box for every attachment you run. For a spreader, that means your existing ISOBUS terminal can control the machine directly, with no extra screens cluttering the cab.

The main benefits for a spreader buyer are a simpler cab with one terminal for multiple implements, easier switching between machines, and access to features like section control and variable rate application, where the spreader automatically adjusts its application rate against a field map or GPS signal. It also supports automatic recording of what's been applied and where, which helps with compliance and input planning.

Across the K Range, computerised ISOBUS control is available on every trailed model. On the M Range and L Range, you can specify an ISOBUS controller as one of the control unit options alongside KRM's own Calibrator Totz or Calibrator Icon units, so the right choice depends on what terminal and functions you need. Our team can confirm the correct specification for your tractor's terminal before you order.

Every new Ktwo muck spreader comes with Ktwo's standard 3-year manufacturer's warranty, covering the machine from the date of purchase.

As an authorised Ktwo dealer, Scot Agri backs that warranty with manufacturer-standard servicing and genuine Ktwo parts, carried out by technicians who know the range, so any work needed during or after the warranty period is done to the standard the machine was built to. We also offer field servicing, so a spreader having an issue mid-season doesn't need to come off the farm to be looked at.

Beyond warranty repairs, our team can help plan ahead of the muck spreading season with a pre-season health check, keep genuine wear parts like beaters, chains and rotor teeth in stock, and talk you through trade-in or part-exchange options if you're looking to step up to a higher-capacity model as your operation grows. Get in touch with your local depot to find out what's included or to book your spreader in.

The right spreader comes down to five things: what type of farming you do, your terrain, the size of your farm, what you'll be applying, and how much tractor power and precision you have available. Working through each helps narrow down a range, and then a model within it.

Type of farming and application matter most, since they decide whether you need a fertiliser spreader or a muck spreader in the first place, and that choice is covered in more detail above. An arable farm applying fertiliser and lime needs a KRM machine; a livestock or mixed farm managing manure needs a Ktwo machine; many mixed operations end up running both.

Farm size and the acreage you need to cover in a working day point you towards working width and capacity. A smaller holding or part fields are usually better served by a smaller, more precise machine, such as the L Range's L15 base, which keeps hopper size and weight down for a utility tractor. A larger arable operation covering more ground benefits from a wider working width and bigger hopper, such as the M45W plus or M60W plus, or the K Range's trailed spreaders for bulk lime and fertiliser work. On the muck spreading side, the same logic applies: an ECO or DUO suits a general farm working through its own muck in a day or two, while an EVO or BIO suits a bigger herd, a contracting business, or a farm wanting to shift a full winter's muck accumulation quickly.

Terrain affects both the machine and its control system. On hilly or uneven ground, a spreader with a tilt sensor, such as the K Range, helps keep application rate accurate as the machine pitches and rolls, which matters more as working width increases.

Tractor horsepower available sets a hard limit on which models are realistic. As a guide, KRM's smaller mounted spreaders need as little as 70 to 80hp, while the largest K Range bogie spreaders are built for bigger tractors with ample hydraulic flow. On the muck spreading side, the ECO Range starts at 75 to 95hp, the DUO Range needs 85 to 160hp depending on model, and the EVO and BIO
