Another new 2520

[ArtNH]

Thanks Greg!

My nephew has a new 2320. We spent one 98-degree day two weeks ago taking his 54" deck off and installing a mulch kit on it.

Reason why I mention this is because I cut our grass yesterday and I'm not happy with the results. Deep grass seemed to produce swirls in laying-down grass. Because *I* replaced the blades on my nephew's deck, now I'm wondering if they put my mulching blades on upside down?

(A little bit of knowledge is dangerous.)

Haven't had much time, but I wanted to close the loop on this. The dealer actually did install the 62D blades upside down. So, besides blowing the grass downward, the blades were rubbing the grass to death instead of cutting---hence the circular patterns in the lawn.

We used the 200CX loader to lift the front end off the ground, reached underneath and flipped all three blades and that resolved that problem.

Hey Art bumped into your closing post. My new 62d deck doesn't seem to cut that well and I though it was the lay of the land so to speak.

If I flip my deck over or peek under it with a mirror will it be that obvious that the blades were installed upside down?

Guess I had a brain cramp last evening. I decided to do the unthinkable and read the owners manual. Looks as simple as making sure the cutting edge is on the bottom. I'll check it later this morning.

In case this comes up again, I scanned in a page from the JD manual for the mulch kit. It shows the correct orientation of the blades. You can download it from:

Thanks Art.
I just took a look under my 62D deck and my blade were installed correctly.

And just to verify, I just finished cutting a 2-1/2 acre grass lot and I'm pretty impressed with the 62D deck. Very happy with it. Nice clean cut, very even and consistent.

I would be happier with the Independent Lift Kit if the control was in a more convenient location. Down near my right foot is not convenient. I can kick it back with my right heel, but it's not easy to pull out while reaching way down there. I'd say they took the easy way out with their design, rather than going for ease of use.

In conjunction with a previous post, I used to cut this lot with a little borrowed LT155. Much to my surprise, I honestly believe that the 2520 has a tighter turning radius than that LT155!

Great to hear how well it is going. Can you clarify what knob you are referring too by your right foot? Is it the push pull lever for the hydraulic valve?

 

[ArtNH]

This control (that is down behind your right heel) is mechanically coupled to the diverter valve that is the main hydraulic controller of the Independent Lift Kit.

My guess is that the name "diverter valve" comes from the fact that the hydraulic pressure is diverted from the bucket curling (dumping) cylinders to the MMM lift arms.

With the control pulled forward (you can hook two fingers under it), toward the front of the tractor, when you curl the bucket with the SACV the MMM does not move up or down. With the control pushed aft, when you move the SACV toward you the MMM elevates and the bucket does not curl (or dump); when you move the SACV away from you (to the right) the MMM goes down and the bucket sits still.
