Landpride 5 foot Rotary

[DAP]

I got a 5 foot Landpride cutter last year just in time for major fall/winter flooding.

As such, until this spring it had a whopping 2 hours on it. I've finally got the opportunity to start using it and noticed that while ruggedly built and quite heavy, it oscillates somewhat. By that I mean, it has a definite wobble. I CANNOT imagine anything is bent as it was only used to cut an acre of old grass last fall before the monsoons hit. I believe it behaved the same then as I thought nothing of it. But after using it for some extended hours, I got to wondering what is normal for these things?


By somewhat, I mean not much, but it is noticible. Is this expected behavior or should it run like a finish mower?

Oh .. its hangin off the back of a B7800 if that makes any diff.

Lube the pivot points of the blades and make sure they are not sticking. If they are stiff and you hit something sometimes they don't sling back stright for a while.

I agree with bbse. Make sure the blades are free swinging on their pivots (clean out dried dirt and grass) and check the blades for small nicks/chips that may cause the blades to be out of balance. Jay

Good replies already. I usually power down the cutter (disengage PTO) and restart it once it gets out of balance from hitting a rock or other obstruction. Otherwise, it seems to take forever to get back in balance.

Personally, I don't think you have a problem.

It sure won't hurt to roll that cutter over to ensure the blades are swinging freely (be careful when you roll that cutter...make sure there is no way it can roll over on you when you're examining those blades). You definitely want to keep those Zerk fittings well greased! It probably would be a good idea to lubricate your PTO shaft too. The oscillation you feel could be the PTO shaft rather then the cutter.


These cutters do vibrate. I also have a 5' Land Pride (on it's third season. I operate this implement behind a Deere 790 which is pretty close to your B7800 in size, weight and power.

When you first run up the cutter, engage the PTO at lower (1200-1500) RPM. Let it set for a few seconds (I think the Land Pride manual says 8-10 seconds) while the blades extend), then increase engine RPM to PTO speed. How's it feel then? You'll feel some vibration...more then you would with a finishing mower.

Unless you're cutting nothing more then field grasses, that cutter (which pulverises rather then cuts) is going to shake, rattle and roll. Some of the vibration is going to be transmitted to your B7800 which will also shake, rattle and roll a bit due to it's relatively light weight (your cutter weights about 25% of the tractor weight).

I'd just operate that implement. I think it's more a matter of you getting use to it then any particular problem.

BTW, when I first got my Land Pride, I ran it behind a Deere 670 which is smaller then you B7800 (size and weight was between the B7500 and B7800 Kubotas). That thing really shook that little 670...but it did a heck of a job!

Roy ... it has ALWAYS vibrated somewhat ... ****, it's only got a few hours on it ... I just wanted some confirmation that this was 'normal' for such an implement - and you've provided this.

It is oiled, lubed and I even loosened and slipped the clutch plates this spring before operating it as per the manual.

Thing seems to be overbuilt - no complaints there.

I also run up the cutter at low rpms ... then juice her using the throttle. For run downs, I clutch, slip out of the PTO, and then power down ...

It's amazing how long this HD unit will spin after it's been disengaged. I usually have to lower the implement to the ground to get the blades to stop from its own centrifugal forces.

BTW, I know this will go unnoticed, but with the turnbuckle type 3pt arms and no chains on my B7800, it took over 30 minutes to attached that sucker, using bats, crow bars, 2x4s you name it. Pat's Easy change has it down to under a minute .... with the majority of that used for extending the top link a coupla inches.

I just have to hide from all the folks who own B3030s and ratcheting arms and tilt steering wheels. I coulda bought one but wasn't convinced I shoulda bought one.

That decision got me a free 5ft LandPride rotary cutter delivered and a 7800 watt PTO driven generator and a 1000lb carry all/forks for the 3pt.

Now, do I miss ratcheting arms that much? /forums/images/graemlins/smile.gif

One more tool you may want to get, now that you are a "farmer". Get the largest pry bar you can find. My big one is 4' long and I have a 5' straight bar with a chisel tip. I use them to pick up and slide my Woods Brushbull 600 that is over 1100 pounds with chains. Also a gannon box blade that is about the same. The proper tool makes a big difference!

"It's amazing how long this HD unit will spin after it's been disengaged"

Yep, mine takes a minute or more to spin down. When I'm ready to shut down, I put the transmission in neutral, lower the engine RPM to 1200-1500 (PTO is still engaged) for about 20-30 seconds, then disengage the PTO. Those big blades will still spin for a while.

Same here...when I first got my cutter, it was a 20 - 30 minute operation (very frustrating) to hook up. I've also got Pat's system...so much easier!
