Rear Blade Rear scrape blade

[MechanicalGuy]

Another reason why I keep my blade manual. When plowing snow or grading my gravel roads, I like to turn the blade 180 degrees and work with the back of the moldboard. Not easy to do with hydraulics.

Simple to do with hydraulics. Unpin, rotate, re-pin.

There sure are a lot of "wtf" posts itt.

My tractor is a Yanmar YT359C and I am looking for a heavy duty rear blade 8’ long. Does anyone manufacture a rear blade that is set up for hydraulic but can be purchased without the cylinders. My plan is to use it manually at first and then I want to talk to Brian at Fit Rite about purchasing the cylinders for offset, tilt and angle. Also I would like a blade weight of approximately 800 pounds give or take! Thanks

There are several 8' long blades weighing about 800 pounds (that would make them medium duty, heavy-duty blades are over >1000 pounds for an 8'er). Most are available with standard mechanical and optional hydraulic adjustments. The main issue is finding one that works with a compact tractor's category 1 3-point hitch as some like the Bison listed above require a category 2 hitch. One example would be Bush Hog's 91-08, it has a category 1/2 hitch, weighs 827 lb, and has standard mechanical and optional hydraulic tilt, angle, and offset.

I have almost exactly the same blade jyoutz does as that blade is also made for JD under contract and sold as the Frontier RB22. It's a category 2 only unit and would be a lot of blade for a ~55 HP compact tractor. I have only the mechanical controls on it and have not had any issues with the blade "getting away" from me when adjusting. Lift it just a couple inches off the ground to adjust the angle and offset, and get the toe of the blade just off the ground enough to adjust the tilt. Lifting the blade too high before adjustment puts a lot of tilt in the blade unless you lengthen the top link a lot, and that tilt does make gravity work against you.

I haven’t had any trouble with manual adjustments for angle and tilt. The offset adjustment can indeed get away from you after you pull the pin on manual adjustment. I fixed that by replacing the telescoping adjustment arm with a ratchet arm. Still manual, but it adjusts by ratchet and doesn’t get away from you. The ratchet link arm costs about $100.

The offset cylinder is a 3" x 8" according to the parts catalog. That size of cylinder from a farm store is $150-200. The parts catalog price is a whopping $830 though!

I bought a 28” (full extended length) ratchet cylinder with 1” pins online for about $100. You must be referring to hydraulic cylinders?

Yes, that is the size of the hydraulic cylinder that would be used for the offset, if one were to use a hydraulic cylinder.

I give another vote for rhino. Mine is a 7 foot heavy duty six way blade. I have hydraulics on the offset and the Horizontal angle. I hardly ever change the vertical angle so I don’t have a cylinder there. It is an extremely heavy duty blade. One thing I like about it is that it has both category one and category two pins so I can use different tractors with it. Good luck finding a heavy duty 8 foot glad that weighs under 1000 pounds!
