Best box blade for my tractor

[marhar]

My Farmtrac 60 (50 hp) handles a 6 ft rotary cutter and a 7 ft scrape blade fine. What’s the largest box blade size (width/weight) recommended for this tractor without overloading it?

Hi Mark. That question is like asking - - How high is UP???

I have a Kubota M6040 and with my grapple and back blade on board the entire unit is 10,000 pounds. The back blade is 96 inches and weighs 1000 pounds. The tractor is rated - 62hp.

Speaking now - just of the back blade. There are times when I do not need the 1K weight. Clearing ice/snow off my mile long gravel driveway. There are times when I do need added weight. I have a 400 pound concrete "cube" that rests on the blade and adds that weight. This is only used if I need to do work on the driveway in the late summer. My driveway becomes concrete-hard in the late summer.

Kubota recommends 84 inch - max width for my tractor. My blade is a foot wider.

The one thing you must understand. Any back blade adds significant leverage to your rear arms, levers & controls. You can and will cause damage if you attempt to grade too deep and hook an immovable object - bedrock.
This will happen sooner with a wider/heavier blade.


When I'm using the back blade - I never grade virgin soil much deeper than two inches - on each pass. I have a whole lot of bedrock on the property.

My first back blade was simply too light. 570 pounds and six feet wide. It did snow just fine. Just not my rock hard summer driveway. Adding enough weight to this blade would have - sooner/later - damaged the frame of the blade.

So - post some telling pics of your current back blade and see what the members think. If the current back blade works for you - I would be happy. Getting too wide and heavy can easily overload the system.

Wasn’t the question about a box blade?

Under the right conditions even a small box blade will anchor a large tractor.
For the op, I would imagine a 6' box blade would be a good fit, or whatever width covers the rear tire footprint.

Check your owners manual usually they have recommendations for implement sizes for CUTs

I think the only difference - Mr Orange - the box blade will tend to contain whatever it digs up. Times are that I know I'm either scraping too deep or have hooked onto something.

The tractor - she no move - and all four wheels are digging holes.

And yes - a relatively small blade - box or open - can definitely anchor a rather large tractor. This is where operator skill comes into play.

50 hp will work a 6 ft box well. It likely matches your tractors width and pulling capacity when cutting or full.
