DescriptionWhy buy the Winton W‑RB04 Box Grader?

If your subcompact won't pull the bigger W-RB graders, this is the one. The W-RB04 is the 4 ft entry into Winton's box grader range, pulling from just 16 HP and weighing 190 kg — matched to the lift capacity of a small tractor. Narrow enough for tight tracks. Heavy enough to bite.

Levelling tracks and paddocks

Front and rear scraper blades shave high spots and drop the spoil into ruts and potholes as you go. The blades are reversible — flip them when one edge wears — and replaceable when both edges are spent. Run it up and down a farm track and the surface evens out under you.

Ripping and seedbed work

Drop the 4 ripper tines to their lowest setting and the grader tears into compacted ground, breaking up pans and opening the soil for drainage. Raise the tines, or pull them out altogether, and the same machine works as a clean grader for seedbed prep.

  • 1.2m / 4 ft working width — the narrowest in the W-RB family, sized for tight tracks and small paddocks
  • 16+ HP tractor requirement — pairs with subcompacts that can't handle the wider siblings
  • 4 height-adjustable ripper tines — drop for ripping, raise or remove for grading
  • Reversible, replaceable scraper blades front and rear — flip rather than replace
  • Cat 1 three-point linkage on a reinforced A-frame
  • 190 kg working weight — matched to small-tractor lift capacity
  • Promotes soil aeration and drainage when ripping worked ground

It works well, used it to pull up compacted gravel drive & level out. Think it would work better if it had some levelling wheels on the back so it could be lowered to the same level each time rather than relying on the tractor hydraulics.

It was worked very well in what I would say tough conditions

We have used the box grader to help level out some uneven and stony ground. It was worked very well in what I would say tough conditions and we are very happy with it. I thought I had some footage to send you but I can’t find it! It will certainly be back in use in the spring.

The WRB4 has been really useful for breaking up the compacted gravel and has allowed us to grade the areas before finishing off with a springtime. WE have used the WRB4 to grade soil areas around a new building and back filling drainage trenches it has saved many man hours.

I’ve used it a handle of times since joining the club in the last 3 months. Andy and the team have managed to use it quite a lot before I arrived with levelling paths etc. I defiantly would recommend to others

It's been a great bit of kit and I'd highly recommend one

It's an interesting bit of kit and the first time I used it to sort out the drive it wasn't very successful. However, with a bit of perseverance it's really proving to be invaluable. Teeth dropped and with a couple of neighbours stood on it, it has ripped the drive up really well and allowed me to get rid of a lot of potholes. Levelling is tricky and you do need to use the top link to get the angle of attack right to achieve the best results. Next move is a hydraulic top link!! I've also used it to take out some anthills in the paddocks and it was brilliant for that. So, in summary it's been a great bit of kit and I'd highly recommend one. But, you do need some experience to get the best out of it. 5 stars for me!!

Hi Niall, thank you for the detailed feedback. Using the Winton WRB5 without a top link is new to me! We definitely recommend using all 3 links, as this allows the tractor to exert its weight onto the box grader so that you don't need to add neighbours on top of the grader. As a quick Health & Safety announcement to anyone reading this: Please do not stand on or near any machinery we sell when it is in use!

It’s robust and easy to use

This device has been an excellent purchase. It works as expected, being used with my 1959 Massey Ferguson. It’s robust and easy to use.
