Fertiliser Spreader

4 Tonne

4 Tonne

New Zealand’s favourite spreader.

Known for practical design and easy to use operation, SAM Fertiliser Spreaders are developed from over 70 years’ experience. The features in today’s machines are the benchmark for fertiliser spreading throughout New Zealand.

Choose a SAM Spreader for extreme reliability and mega-solid construction. They provide an accurate spread pattern, with ease of operation and fast spare-parts servicing.

SAM Fertiliser Spreaders are capable of spreading all chemical fertiliser. Including; superphosphate, urea and lime between 40kg - 2500kg/hectare. With spreading widths of up to 20m (superphosphate).

They are available in single or tandem axle with capacities of 4, 5, 6 and 8 tonne. All come standard with a 400mm wide floor-belt. 

Keep it simple with a hydraulic clutch to standard ground drive, or upgrade to the latest smart, accurate e-Spreader with load cells.

Smart features

  • More stainless for longevity
    More stainless for longevity

    Majority stainless at the rear of the machine, extends longevity of gear where you need it most. The stainless discs are run via enclosed stainless spinner tubes and two well-proven hydraulic motors. Easily adjustable tapered roller bearings keep disks tight.

  • Industry leading coating protection system
    Industry leading coating protection system

    All chassis's on SAM Spreaders have seen a new evolution of painting procedure. This is for extra corrosion protection. Firstly a blast then a thermal-arc spray followed by the SAM coating difference. It is mega tough stuff!

  • Strong plastic bin
    Strong plastic bin

    The polyethelyne plastic bin has proven to be extremely reliable. They are strong, corrosion resistant and UV-stabilised. Fertiliser also slips down the sides and washes off easily when you are cleaning your gear.

  • Even, accurate spread
    Even, accurate spread

    The SAM twin spinner disc design gives an accurate and consistent spread pattern across a range of products. Quick and simple rate setting is by adjusting the rear door.

  • Computer control box 1 Computer control box 2 1
    Computer control system

    You can also add a computer control system to replace the standard ground drive. This gives hydraulic floor speed rate and control. This easily connects to the likes of TracMap or Trimble to give variable rate spreading from the cab of your tractor. More info below.

  • Less cleaning with mudguards!
    Less cleaning with mudguards!

    Mudguards are moulded from UV-stabilised polyethylene, and resistant to most chemical and organic fertilisers. Debris chips to the chassis and running gear are reduced and less cleaning required. Mudguards come standard on all tandem axle models below 8 tonne.

  • Patterned rubber floor-belt (400mm wide)
    Patterned rubber floor-belt (400mm wide)

    Provides a positive non-slip feed of fertiliser onto the spinner discs. A patterned two-ply rubber floor-belt is riveted to corrosion protected steel bars, welded to high-tensile chain. Stainless skirts run alongside.

  • Swivel coupling
    Swivel coupling

    Swivel couplings are now standard. They are great for varied terrain. You can choose a donut eye for coupling with a quick hitch or the insert option for tractor coupling.

Roll Top Feature 1 v2
Roll-top cover

Upgrade to an easy to use roll top cover. This is a simple canvas, frame and bungy system. The handle rolls your cover up, tucked out of the way when not in use.

It is mounted on the rear of the machine so you can load from both sides.

Standard cover 1
Standard cover

The standard cover is manually thrown across the load and fixed in place with bungys. Keeping it simple.

Cover 5
Quick cover

This cover concertinas from front to back. Simply wind the handle.

Mesh S 1
Internal mesh

This mesh fits inside your bin. It helps to prevent lumpy urea upsetting your spread rate and it also stops large objects dropping down and damaging the belt and gear. Great for spreading crusty Urea.

Remote greasing S 1
Remote axle greasing

Remote axle greasing saves you time and effort by giving you access to all axle greasing points. They are raised together in a bank in an easy to reach location.

A very effective way to improve machine maintenance, without having to jump under your machine. So keep that gear greased - no excuses!

Tyres 2
Tyre upgrade

We have tough high performing tyres to suit any application. They are chosen for their quality and durability. 

We can change tyre sizes to suit your specific needs. The 4 and 5 tonne tandem spreaders use 11.5 x 15.3 tyres but these can be upgraded to larger 400 x 15.5 tyres. The 400 x 15.5 tyres are standard on the 6 tonne spreaders but can be upgraded to the 500 x 17 tyres.

550/60 x 22.5 tyres are an option on all single-axle models. These larger tyres can be excellent if you have softer, wetter conditions. 

Load cell S 1
Load cells

Computer drive (e-Spreader & Topcon)

Load cells are added to any computer controlled machine. It is really the only way to get true accuracy because you are actually weighing the product in the bin.

e SpreaderV3
Smart e-Spreader

Any SAM Spreader can be upgraded to an e-Spreader at the time of build. The floor speed is controlled from a screen in your tractor cab. This replaces the manual drive. You can set your rate easily from in your cab and get your spread rate very accurate. 

The SAM e-Spreader is super easy to calibrate and every e-Spreader has load cells. Fitting load cells is the only way to get true accuracy because you are weighing your product. This technology means the correct application rate is applied regardless of changes in forward speed.

It also integrates easily with third party GPS systems such as TracMap. You can see how many hectares you have covered from the screen and the weight you have applied. This live data means proof of placement is easy. If you are already using a third party tracking system you don’t have to reinvent the wheel!

80 - 90 l/min of oil flow from your tractor is preferred.

Ask us about the new ISOBUS compatibility upgrade.

Topcon 1
Topcon control

Adding the new Topcon computer control system means the correct application rate is applied regardless of changes in forward speed or changes in product density. 

By adding the load weigh scales too, the weight of product in the bin is integrated, allowing dynamic rate control. It is continuously using the weight of product in the bin to check spread rate accuracy.

This computer control system is ISOBUS compatible so can function with the majority of new tractor consoles.

Brakes 1
Brakes

Brakes are available for tandem axle machines. They are usually located on the front hubs only. The brake system chosen had been well-proven over the years and is very reliable.

Lights and flags S 1
LED Lights & flags

If you are using your machine on the road you will need a set of lights and flags. The flexi mounting boards are made from durable plastic, hardy for knocks and general wear and tear.

Weatherproof lights are LED and plug directly into your power source.

Swivel coupling S 2
Swivel coupling

Smaller spreaders come standard with a fixed coupling. The 6, 8 and 9 tonne spreaders come standard with a heavy-duty swivel coupling.

Swivel couplings can be added to smaller machines if required. They are great for varied terrain. You can choose a donut eye for coupling with a quick hitch or the insert option for tractor coupling.

Skid 1
Skid

If you are using your machine with a quick hitch you will want to include a skid on the drawbar. 

Please also specify that you would like a donut eye on your tow eye.

Safety step
Safety steps

Adding steps to your SAM adds an extra layer of safety. They provide strong, stable stepping points and grip bar. They are an optional extra on the smaller models and are included as standard in the 8 & 9 Tonne.
