Rear Blade Bison Rear Blades

[Phred]

Anyone have a bison rear blade?

Several reasons I am looking at the Bison:
1) For larger 4wd tractors the light weight units are not an option. Tear into rocky ground with a large tractor in 4wd low gear, and the blade will rapidly develop a new undesired shape. The result is that a heavy duty unit with a minium cost of around $800 is probably the baseline.
2) The bision is very heavy duty. The heavy duty 9' is just over 1000lbs.
3) You can add hydraulics to the NHVH- -XHD series after the fact, without the up front sticker shock.
4) A new unit is ~$1300-1400 for 9' without hydraulics. Similar woods blade is a good deal more.

Anyone have a good or bad expereince?

Hey Phred,

Never heard of them before your post. Sure make some h-d looking equipment though. Have you seen one in person yet? If so how'd it look?

Woodbeef,

Yes. A local dealer has one on the lot. Its CAT 2 and all manual adjustment. But it has mounts for hydraulics on tilt, angle, and offset.
These things are very heavy duty, and appear well built.

Almost as heavy duty as a woods RB990, (~1400lbs) but much cheaper.
Its a good deal heavier than the woods RB850 which is about 750 lbs.

I would rather have a RB1010 with the rear wheel and hydraulics but thats almost 3K worth of rear blade! /w3tcompact/icons/crazy.gif.
Local dealer had one of these on the lot for a few days that had already been sold to a customer.
With a full set of hydraulics that was one heavy duty blade.

Hey Phred,

Very impressive company and equipment! I e-mailed them as soon as I saw your post. They got back to me early the next day! Very quick customer service,even though they are not sold up here yet.

Woodbeef,

Well I hope so. My NHVH-270-XHD will be dilevered next week.

Once it comes in and I have some time to play with it I will take some pictures.

shouldn't Bison give you a blade for free considering your occupation ????

One can always hope,eh?

Guys,

It turns out this is a great blade.
Very well made. Might just outlast me.

Here is an up close shot.
One of the things I like about this blade is that It already is all set up for hydraluics. I just have to add the cylinders.

Hi Fred...

It certainly looks to be an extremely hefty unit from your pictures... can you get a "front" shot of the A-frame...?

If you put a couple 3/8" side plates on that brute... it will become one big mean 9' box blade... /w3tcompact/icons/blush.gif

The index plate looks about 1" thick... and everything is ready for a rear wheel, hydraulics all the way around... the moldboard looks very well designed with the enclosed gussets/support across the entire span, with end support as well for "ditching"...

Fred... I like it...! /w3tcompact/icons/smile.gif

Can you explain their number/model system...? 240/270/300 ? I checked their website, but don't quite understand the differences...

You have one mean blade there Fred... you'll break something on the tractor before that moldboard bends... /w3tcompact/icons/eyes.gif

John,

Here is another shot. Once I take it off again I will try to get a shot of the A-frame from the tractor point of view.

Two main uses for me; Ditch making and road maintance. While I am a novice at this I think end plates would get in the way of the ditch work, although they would probably help alot for gravel spreading, etc...

The moldboard is 5/16" thick. I can drag this 4wd tractor to a halt with this guy and thats with the transmission in crepper range gear 1! Doesn't seem to phase the blade at all.

These folks make three basic lines in the heavy duty category. NVH-###-XHD, NHVH-###-XHD, and an NVHL-###-XHD. The three numbers ### are either 240, 270, 300. The 240 is 8', the 270 is 9', and the 300 is 10'.
The difference between the NVH and the NHVH is that the extra H stands for hydraliucs. The NHVH model has all the mouting points for cylinders on all three adjustemnts, and can come with the cylinders already mounted if you elect. The cool thing is you can get the NHVH without the cylinders like I did. The latter on you have the optiion of adding the cylinders on the cheap from TSC or similiar.
The NVHL is an even heaveir duty model with a 1/2 mold board. This one is rated upto 150 HP.

This company does not offer a rear wheel like the very heavy duty woods. I could not figure out any real advantage of the rear wheel and the woods cost was much much higher.

Hey Phred,

Nice looking unit there!! It sure looks well put together and built to last. What's the quality of the steel look like?

 

[Phred]

Woodbeef,

Fit and finish is good. This is not just thrown togehter.
Similar in quality to the major brand names.
Paint job is well done also.

Although I have not had it long, I worked it very hard the other day by buildling a couple of drianage ditches. Made all four wheels spin on several ocasions without any problems. I don't think my tractor is capable of breaking this blade.
Then again they claim a rating of 120HP.
