2320 and 54D MMM

[Spud67]

Here is another question that came up tonight when switching from the hydraulics for independent lift for the mower and the hydraulics for the FEL. From the dealer they recommend disconnecting the grey and yellow for teh bucket hydaulics and the independent lift for the mower is yellow, connected colour for colour. The trouble I find is going back to use the bucket, connecting the hyaulics for teh bucket are really difficult. It feels like there is pressure in the hoses from the bucket and it is very difficult to connect them to the tractor. I equalized teh presure according to the manual by moving the SCV several times back and forth and left and right but still had no luck with the yellow connector.

Anyone else have this sort of trouble with connecting hydraulics?

I just got a 2520 (3 hrs on it now) rain, rain, rain. I also got ind. lift kit, but I also got the mower/loader diverter valve so the mower hoses are always hooked up. I only have to attach/remove the FEL hoses. I don't know about the pressure problem as I haven't had a chance to remove the FEL yet...hopefully tomorrow

First posting for me, I like all the valuable information sharing that is occurring here. First a little Hx, after moving to an acreage/retired Xmas tree farm last year I was blessed with a nod from *the boss* to purchase a 2320 (went in looking @ a 2210) and numerous attachments. Had to upsize since the ROP on the smaller units wouldn't fold/fit in the garage. I have since put about 120 hours on it and use it pretty much everyday. It currently sees alot of brush work, but am about done clearing dead trees. I too have made alot of *rookie* mistakes with her attachments, but it does get smoother with familiarity. One modification I made was to my 62D mmm. The front turning floater wheels on my deck would scalp my yard when I would go over some uneven spots. The manual reccomends using JD spray lube on the shafts. I would routinely apply said lubricant, to find it really didn't free up the turning shaft. A couple of guys @ work have similar problems with their mmm wheels. This winter I drilled, tapped, and installed grease zerks toward the rear of the housing hoping this would remedy my problem. So far it seems to work pretty slick.

Welcome to TBN!
That very issue with the MMM wheels was a hot topic here for a while, and adding the grease zerks as you did seamed to be the best cure. In fact I believe the newer models have them installed at the factory now...

There IS pressure in the hoses just from the weight of the bucket resting on the cylinders, it is compressing the fluid. The only "good" answer is to rest the bucket on the ground or a block of wood to neutralize the weight of the bucket when you need to re-connect the hoses. Or, Better yet... when you put your MMM on take the bucket off the loader arms if you can't just take the whole loader off.

The other more costly option is to get the diverter.

Hello all, I tried the hose connections again today and it worked this time. I had the bucket sitting on the ground last night but I guess I never moved teh SCV around enough to equalixe all the pressures. This morning I went out and moved the lever around about five times in each directions, bend down and pushed the yellow hose on for the bucket with no trouble. The manual is correct, I wasn't equalizing the pressure on the SCV as much as I should have.

I must have missed something here. Why are you hooking and unhooking hoses between the FEL and MMM? Do you have something else hooked up to the hoses using one set?
On my 2320 tractor, the SCV operates the FEL, and the same lever that operates the 3 pt hitch also raises and lowers the MMM.

Also, my tractor is one year old now and it came with the zirk fittings on the MMM deck wheels.

Kennyd, thanks for that idea. I tried shifting the PTO selector while attempting to install the deck shaft today and it sure makes aligning the shaft much easier!

You are quite welcome...my pleasure to help

They have the "independent lift" option that uses a single hydraulic cylinder to raise and lower the deck instead of it being hooked to the 3PH
