Here are a couple of pix... Amounted to $300 all in for new bushings, bolts and such. Now to install.... Oh, They are about a pound heavier than the original... Put them on the food scale (wife was not happy).

And for the follow up. There is a bit more vibration... But once at speed it is gone (and I am talking very little and I have not run the mower in a month).

The lift built in is a question mark. Clearly the tractor is throwing stuff up onto the top of the deck. Wether it is lifting the grass and stuff is a question

But the big news is that I hit a tire. With a rim. Made some noise, did not ding the blades. So far so good....

And finally... First thing is that these blades do create lift. And so much dust you cannot believe it. I am choking on my tractor where lat week I did not notice a thing... Second, they do swing heavier, thus cutting stuff up a lot better. But, I think because of the lift on the steel, I have now had two sizeable limbs get jammed under the blade and mower deck. Smoked my belt pretty good. The ear muffs I wear really cut down the noise. Not sure if I like that or not. Thinking about re-mufflering the Deutz. Or sending the exhaust note to the back... Not sure how much that would quite it down...

Vibration is more noticeable as I said before.... But the CUT I had a while ago with the 4' brush hog shook like a baby at a nanny convention...

Also, I need to install the bumpers everyone talks about. With the flare at the ends they get jammed in pretty quick

Finally, I think the blades have swung completely around. After 4 hours of mowing brush, I looked under the deck and a couple of the bolts had started to back out. I don't really want to use loctite on them. Any thoughts?

Anyway. All in all I would say it is a better deal than the blades from PT. $300 is a tough nut to swallow, it would have been $160 or so from PT with shipping. But, these things are really really tough.

Dear Carl,

Is there such a thing as too much lift? :)

I am glad to hear that they cut well.

Why no Locktite? While it bonds well, it probably does a good job of filling the voids in the threads, so that you won't pack it with dirt. So, it might be easier to get out than not using anything.

Let us know what you do with the exhaust. I'm not sure that there is ever a good place for it to go.

All the best,

Peter

I'd go ahead and loctite those suckers so they don't back out on you.

The baby thing I made up on the fly. Have to say you should enjoy it, I am rarely funny...

OK. Will loctite the bolts in. Now I have to figure out what in the heck is up the the spare holes. Either they cut the bolts off at the factory, or put them in on the other side... Grumble if they are on the other side...

Instead of Loctite, what if you used a little silicone on the threads?

It could prevent the bolts from backing out yet be easy enough to use an easy-out if one shears off.

It's what I'd try first and I have both various Loctites and silicones on the shelf.

And congrats on the shaking baby thing!! Excellent!

Carl. Yes there is such a thing as to much lift. While it does make the grass stand up to be cut, it also will suck the dirt right out of the ground. I used to ride the 33 in Snappers a while back. and with the bolt on lifts, it would suck the dirt out of the ground. It did a very good job of sucking up leaves, beer cans, pine cones, pine needles, etc. With that said, if I had known that you were going to add a permanent lift, I would have suggested the bolt on lifts like on the 33 in Snappers. You could bolt them on when needed and take them off for bush hogging. Zero lift blades are good for rough cutting. The centrifugal action, will sling the grass or whatever out from under. On a zero lift blade, you could have the backside sharpened also, so that you could reverse the blade when necessary. Did you say what kind of steel the blades were made from.

I will have to check out my flail mower to see how it does in different grasses , weeds,vines, etc, and give a report. It can do a finish cut to the extreme of slinging a hammer type sharpened wedge around to chew up heavy stuff. I had the manufacture send me samples of the different types of flails. The only thing is that I need about 52 of the same kind.

Phils... Silicone, Are you referring to like Bathtub calk silicone?

JJ - T1 steel. I am committed to the lift. Didn't think anything could survive being bolted to a blade. Also the blade are now 1/2" thick up from 3/8"

Altavista. As you are the resident expert on the 1850, what is your thoughts on the Mower? I would assume it is the most heavily used device on your system. Have you put in bumpers and stuff? Love to hear about your mods...
