MX6 in a 4310

[rockyridgefarm]

Deere doesn't rate the 4310 for a MX6

I got to try one today. The cutter is fantastic. We are VERY hilly, and there were no problems handling it. The cut was great. The cutter is MUCH noisier than the LX, but then, it has chains, which seem to be the cause.

The only problem seems to be that it severely lugged the engine on startup. After that it ran just fine. We got better at starting it, as the day went on.

My wife did hit a 6" long piece of 2" schedule 40 pipe. Big Bank. The pipe got cut, but not a mark on the cutter. Fortunately, no one was hurt...

That's pretty cool. I didn't think the 4310 would be able to handle it. Does it make the front end pretty light, even with the loader? Another thing that I am wondering. If something should go wrong, would it affect the warranty at all?

Sorry for the dumb question Mike,but what is exactly a MX6. I think I could make a guess, but not sure????. Thanks

It's John Deere's medium duty rotary cutter with a 6' cut, look here for more info.

The last I knew, there were no stupid questions /forums/images/graemlins/grin.gif

Sound like you need a new pic under your name (hint,hint...)

With the 430 loader, standard bucket and loaded front tires, there is NO handling issues. I have worked that pretty hard, no babying it. I didn't want to be extra soft and agree to buy it THEN find it made things tippy. So I have raced up and down hill with it raised for transport. I have pulled out from a standstill will full juice at all ranges. I haven;t tried without the loader, I know it will be light up front, but am pretty sure it'll be manageable.

As to warranty, it was my dealer that thought I should be using it, he assures me there are no issues. I will talk to him about it lugging the engine, just to make sure...

what type of stuff are you cutting with it?brush grass etc.

 

[rockyridgefarm]

Am I reading this correctly? it looks like I oughtta be at 2000 rpm when starting the pto for maximum torque and Hp. then move up to 2600 (for pto speed...)

thanks to jmIII who oeiginally posted this graph...

Very light brush and heavy grass. I am maintaining my pasture....

Looks like your reading the charts correctly, however - unless you have a slip clutch on that cutter, engaging your PTO, at that high RPM, will almost surely, take out your shear pin.

I have a 4310 and bought a new/discontinued JD 513 cutter. This is JD 5' medium duty cutter that has been replaced by the newer model.

It does not have a slip clutch on the cutter, just a shear bolt. Even at idle, when I engage the electric PTO, the very sudden and abrupt torque on the cutter, causes the swivel blades to snap out, and about 1 out of every 3 times, takes out the shear bolt. I would sure be careful about engaging the PTO on one of these 4310s at any speed above idle. Even if your cutter has a slip clutch, the violent change from nuetral to 3/4 RPM on the gears, shaft, clutch, etc., is going to cause a lot of premature wear/tear on your equipment.
I would only engage PTO at idle, then encrease RPMs to obtain the best cut for the situation.
On my rig, without the 420 loader on, with the 513 deck raised up off the ground, the front end gets real light. No loaded tires or front weights. Hit a dip at speed, and you would be pullin a wheelie. With the deck down, and tail wheel on the ground, it works fine even on very steep hills.
Have fun,

PS: Sorry I never replied to your e-mail, had to have surgery on left leg, been out of it for a couple of weeks. Still have same oversize tires on tractor, can't even drive it right now.
See ya.

Mike Mc,

As a comparison, I use a 5' brush cutter (JD503) on my 755 (15 PTO HP) with no problems. The book says the 5' requires 18 PTO HP minimum but I bought it anyway based on the dealer recommendation. I have never regretted it.

For start-up, I would use the lowest RPM that you can that does not excessively lug down the engine. You may have to experiment a little. For best response, avoid starting with the cutter blades down in the brush.

"As a comparison, I use a 5' brush cutter (JD503) on my 755 (15 PTO HP) with no problems."

I ran a 5' cutter through some really thick brush with the 16 (PTO) HP tractor with excellent results. Most of the stuff I mowed was as high as the hood (or better). The cutter, a Land Pride, has a recommended minumum PTO HP of 20, BTW.

The 790 I have now has 24 PTO HP and is probably a bit better suited to the cutter. But if I was to buy a cutter today, I'd buy a 6' unit.

Your 4310 has 28 HP at the PTO. Reckon as long as you use a modicum of common sense, that 4310 should have no problems with that MX6.

As a few others have mentioned, engage that PTO at low RPM. Say...1200 or so. I also used the foot throttle to give it a bit more if necessary. Those cutter blades are hinged and have to pivot out (from centrifigal force which is really another from of inertia). Until the blades are straight and rotating, the cutter will rattle and thump quite a bit. Lower RPM allows that to happen with less stress on the drive train. Engaging the PTO at higher RPM is the same as dumping the clutch in a vehicle.

But, if you're cutting light brush and heavy grasses, why do you think you need a medium duty cutter?

Good point! I will be sure to do that. I certainly don't want to tear up the tranny...

I just think you should send out the professional pic taker (your daughter if I remember right) to get some new pics of the set up. Have her leave the super zoom in the house this time though /forums/images/graemlins/wink.gif

same way we do it on our 4310 bring it a little off idle then engage pto drive,the cutter jumps around a liitle until the blade swings out then slowly increase to pto speed,this is with our kk5' model.
