Hydralics v. Manual: Rear Blade

I'm narrowing my search for a good rear blade down to the Bush Hog 70 or 90 (manual), Rhino 800 (manual) or Woods (either the HBL84-2 or RB750, both manual).

The most attractive currently is the Bush Hog 70 with a 7' blade, which a local tractor place has in stock. But I wonder. . .

How much advantage do I gain by investing the extra $$$ for a hydralic rear blade? Rhino's 950 or Bush Hog's 121 are attractive, but I don't know prices. I suspect they are not cheap.

So - are the hydralics worth the money, or what should I take into consideration that would make hydralics worth it?

Thanks

George

George, a neighbor of mine has a Bush Hog 121 blade and it is a very well built blade. I just bought a BH 176 and love it. The hydraulic offset is very nice. If you only have one set of outlets it might be a little more unhandy to run but a manual or electric selector valve can remedy that fairly easily. Last I knew the 121 blades were around $3200 here in NE Missouri. The "farm store" blades will grenade long before the BH will. My humble opinion. Mike

George The Bush Hog 121 that I have came with four quick connect coupleings. One supply and return for each of the two cylinders that control the tilt and angle. Nothing else came with the blade. When I bought my tractor, I ordered the spool valves with two control levers because I knew I would purchase the hydraulic blade. If your tractor does not have the two spool valves you probably need to talk to the implement dealer and see what would be involved to fit your machine with the necessary valves. It will take two valves to operate the tilt and angle on the blade. It may be that an add on valve set would not be too expensive. But I don't know.

OK - thanks for this. I know I have the valves, and there is one lever that I can remember - I'll check and see what else is there tomorrow and talk to the JD people. . .

Many thanks!

George

heres a cheap way out if you only have one set of remotes...keep in mind you'll need hoses and couplers too.

George, listen to the wife! The extra money that the hydraulic system costs will be far offset by the pure enjoyment of sitting in the tractor seat and being able to contol that blade. Not to mention the wear and tear on the muscles and tendons in the old arm and back. One slipped disc or one torn rotater cuff would more than pay for the hydraulic system on that blade. Wow, sounds like I am a saleman for the scrape blade compay. Anyway, I am a big fan of sitting on the tractor seat and being able to adjust the blade. Good luck in your search.

This raises another question. I've downloaded the Bush Hog 121 manual from their website, but it doesn't indicate how it interfaces with the tractory hydralics or how its controlled from the seat.

I have POP valves with one control arm on the valves. Is there a seperate box or something that goes between the pop valves and the lines to the blade?

Thanks again.

George

This is very helpful! Thanks

That 121 is looking pretty good, particularly since the wife seems positively inclined toward the hydralics.

And the thought of just sitting there and controlling it definitely has its appeal.

Now to find the $$$

Thanks

George

I have a Bush Hog Model 121 7" hydraulic rear blade with tilt and angle control. After years of maintaining a road with a manual blade, I will never go back to manual again. All that cranking and pulling on a manual blade just became too much wear and tear on this old body. It is so easy to sit in the tractor seat and adjust the tilt or angle with a lever. The extra money is well spent on the hydraulic control. Keep in mind that my glowing review is taninted by my age and physical condition. Let us know how you like the implement you purchase.

Saw this and your earlier thread on rear blades. One thing to look at is the width of your tractor wheels. Mine are just 2" under 7'(82"). A 7' blade sitting on any type of angle to push snow or whatever will not give clearance for the wheels so an 8' is the minimum for me.

I'm looking to mount one on my 3 pt hitch (home made) on my front end loader where the bale spear is now. I think I can get more control and better leveling and better pushing of snow and road maint and waterway maint and building with a front blade so I avoid driving over the work area or blading in reverse.

I'm looking at a 8' long 3 pt blade by King Kutter. It has a manual swivel for angling the blade forward and back. I would then cut the main frame in two at the halfway point and weld on 2 round steel plates with holes drilled so I can swivel it up and down for working ditches and waterways. Basically make it work like a grader blade. The trick will be to drill the holes so I can make some minute adjustments and still allow pinning or bolting with 2 but probably 4 bolts or pins.

For what little I would do, trying to spend a lot for hydraulics that would just sit around doesn't work.

If anyone has any better ideas, I'd like to hear them.

how much is not climbing up and down off tractor to make adjustments worth to ya??? neighbor has a hydraulic blade...he can maintain our shared ranch road in about a third of the time it takes me with a manual blade...i'm in the process of scrounging parts to build a trailer type hydraulic rear blade...longer wheelbase makes a smoother finish.
