B3030 - Use of 3pt vs MMM

[Lindy]

There is a brace/bracket at the back of the 72 inch MMM that limits the travel of the MMM. I'm thinking the 60 inch can be pinned up but not certain about the 72". I'm hoping someone with a 72" will comment.

Bigtwin, per your request -- here's a pic of what the setup on the 72" MMM looks like at the front. The 72" deck comes with 2 clevis pins and rings that you use to pin the deck up to the frame. This is the obvious/easy part, although actually getting those pins in the holes can be really difficult. I either have to get my wife to help lift the deck up by 1/2", or I have to get a jack to lift it up a bit. I can't do it by myself. There's not much room to move your hands around in there either when the deck is lifted .

When you HAVE THE DECK ATTACHED, the rear linkage should look like this. Notice that the "rotating bracket" is swung and locked into the upper position with the ring attached. This rotating bracket has to be in the UP position in order for the deck to be raised fully to the up position.

When the deck is NOT ATTACHED and you want to pin up the deck LINKAGE, notice that the rotating bracket is swung into the down position. This bracket will hold the linkage up and out of the way if you want to use a 3pt implement. This is the setup I use all winter -- I pin the LINKAGE up and out of the way since I only use the snowblower on the 3pt in the winter. I'm guessing you have this bracket swung into the DOWN position, and your deck won't lift high enough to pin up at the front. The delivery guy warned me exactly about this when they dropped off my tractor!

The front setup on the 60" MMM, which I also had before I traded it in on the 72" MMM, was a little bit different. There was a "dual pin" setup that had to be rotated once the deck is lifted up by the 3pt. It was a lot easier to use the front pin-up on the 60" deck than it is on my new 72" deck.

The rear setup is similar on both decks.

I went to pick up my B3030, 72 MMM and tiller. We found that we could not lock the MMM in the upper position and it appears I'll have to take the tiller off when operating the MMM. Lindy, what method are you using to lock the MMM in the upper position?

BTW, this is correct. You DO have to take the tiller off to use the MMM (because you use the 3pt to raise/lower the deck, and there's no way to "pin up" the 3pt arms in the back). On the other hand, you don't have to take the MMM off to use the 3pt tiller. In this case, you just pin up the mower (then the 3pt has no effect on deck height).

It's like this because you CAN pin up the MMM, but you CAN'T pin up the 3pt arms.

I know, It's kinda confusing.....

How about this guys, I know Kubota 3030 has a rate of drop knob for the lift cylinder, you can turn the knob CW and it locks the 3 point where it is. Meanwhile your hyd pump is running and thru hyd spool returning the fluid back to the reservoir. if you have a separate spool valve for your MMM then you should have no problem lowering or raising the MMM with no effect on 3 point lift.

JC,

The B3030 uses mechanical linkage to the 3pt for raising/lowering the deck. I don't know if there's even an option for ind. hydraulic deck lift on this tractor. If there is, I'd like to know. But my dealer didn't seem to have any info on it.

Oh Okay, My idea only works if he mmm deck is lifted or lowered Hydraulically. My bad.
