MX6 in a 4310

755inNY · May 1, 2004

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?

I would only engage PTO at idle, then encrease RPMs to obtain the best cut for the situation. 

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.
