FREQUENTLY ASKED QUESTIONS

Check out our FAQs. Get the facts about our Chaser Bins and agricultural machinery, including the innovative Nyrex & Grainking product ranges.

What size is best suited for my tractor?

As all our bins come standard with brakes, you are able to use a smaller tractor than normal. However, we still recommend that for an 18T chaser bin you would need 180HP or greater tractor to operate it.

  • 25T chaser bin requires 230 hp minimum.
  • 30T chaser bin requires 280 hp minimum.

Does the Dual Purpose Bin experience contamination?

We have dual sweep augers feeding separately to the single discharge auger, so you will see some contamination. You should be prepared for approximately 2 x 20L buckets of contamination if you do not empty the discharge auger between fills. However, as field research has shown, Grain King customers consider this minimal contamination that is far outweighed by the cost benefits of owning a single piece of machinery that is so effective at seeding and at harvest.

 

What is the auger size?

We have two different auger sizes, a 14 inch and an 18 inch. The 18T bin comes standard with the 14 inch and the 25T and 30T come standard with an 18 inch. However we can do either size on each model bin.

The seed and super bin is only available with the 14” augers.

How many tonnes per minute do you get from each auger size?

Our GrainKing bins feature 14.5”, 18” and the new 24” auger. Below are the discharge rates:

  • 14” Pto/Hyd = 7T/min
  • 14” Hyd/Hyd = 6T/min
  • 18” Pto/Hyd = 10.5T/min
  • 18” Hyd/Hyd = 8.5T/min
  • 24”Pto/Hyd = 20T/min
  • 24” Hyd/Hyd = Not Available

Is it HYD/PTO or HYD/HYD?

All Grain King Chaser bins, Dual Purpose Bins, and Seed and Super Bins are standard with PTO discharge and Hydraulic sweep auger(s) (PTO/HYD). Our Field Bins are built standard PTO discharge/sweep auger (PTO/PTO).

We can configure any bin to a HYD/HYD configuration, but you should be prepared for the amount of oil required to run this set up.

How much oil is required to run my bin?

Our GrainKing bins feature 14.5”, 18” and the new 24” auger. Below are the required oil flow figures:

  • 14” Pto/Hyd = 80L/min
  • 14” Hyd/Hyd = 125L/min
  • 18” Pto/Hyd = 80L/min
  • 18” Hyd/Hyd = 255L/min
  • 24” Pto/Hyd = 100L/min
  • 24” Hyd/Hyd = Not Available

Weigh Scales?

Weigh scales are available from new and as a retro-fit able kit on certain bins.

What tyres come standard?

All our bins come standard with earthmoving tyres. The tyres for each model is :

  • 18T – 23.5×25 earthmoving tyres
  • 25T – 26.5 x 25 earthmoving tyres
  • 30T – 29.5 x 25 earthmoving tyres

All tandems come standard with 26.5×25 earthmoving tyres.

We offer a wide range of floatation tyres varying from 750mm wide to 1050mm wide.

Do I need an escort?

Chaser Bins and Dual Purpose Bins without a 500mm auger ext and 3m wheel centres do not require an escort vehicle (they are under the width of 3.5m). The Bins however will need the appropriate signage when towed on roads (flashing beacon, oversize signs and red and yellow flags on your widest points). Seed and Super units, Chaff Carts and Field Bins all need x1 escort out the front of the towing vehicle and appropriate signage on the units also.

What’s the difference of a GrainKing Tandem axle?

Tandem axles are the most unique feature on Grain King bins. They feature heavy duty leaf spring suspension, hydraulic operated brakes on all wheels, rear steering axle (hydraulically lockable for reversing and fast paddock/road speeds), heavy duty axles and rear steer shock absorbers. The purpose in having this set-up is to ensure the tractor has minimal strain when towing the unit, lower the weight on the drawbar but keeping a low centre of gravity, minimising scuffing when turning and reducing soil compaction. Our competitors use a bogey axle set-up with no steering creating a large soil disturbance when turning in the paddock and also offer a walking beam tandem axle which can increase compaction with the rigid movement in the walking beams over small contours and large paddock runs. The Grain King tandem axle is the Rolls-Royce of tandem axle machinery.

Why do brakes matter?

Having our axles made in Europe means that the quality and safety of the axle is at its best. Tractors in the modern era can travel up to 80kmph while the average level out at 35-40kmph. At high speeds whilst towing an implement or Chaser Bin, you need to ensure you can stop safely a quickly for an unexpected situation. Chaser Bins up to 50T when full will take some stopping at speeds above 10km, having hydraulic brakes will help the tractor slow down before an accident occurs resulting in a serious injury or possible death. Many accidents happen every year when chaser bin operators can’t stop in time safely. The hydraulic brakes are standard on Grain King Chaser Bins so this will not be an issue for you.

Can I move my bin loaded?

Of course your chaser bin can be moved loaded!

However, with field bins do not attempt to move the bin with more than 5T inside any field bin whilst transporting down a road, we have seen many tractors and trees destroyed because of the weight behind the tractor causing the bin to jack-knife and damage the tractor and sheer draw bar pins resulting in the field bin to roll away. The field bins should be towed with a tractor of 250hp and above.
