John Deere 4720 with a mmm mid mount mower belly mower It can be done

Nice job, thanks for sharing! I would love to put mid PTO on my Kubota, get a MMM and snowblower for front... but, I have a 6' finish mower that works fine on pasture and my Ferris ZTR for lawn.. and to be honest, we don't get enough snow to warrant a snowblower on tractor. I have a walk behind that works fine (and a 48" one for Gravely rider).. You have a great setup, again, nice job!

Just some info. I purchased a new 4320 cab tractor with the 72" mmm in 2006. It had the industrial bar tires. Correct on the transport position of the mmm. Later on I purchased a used set of turf tires. If I remember correctly when I had only the industrial bar tires I was able to put the mower into transport mode by using my floor jack under the front roller on the deck and raising it up and installing the pins. Mmm needs to be in the up position to do this. Now this is from memory. When I put the turf tires on there is more clearance to the mmm but I did not raise the up height of the mmm, I left it the same and I still use the floor jack to put the deck into transport mode. I don't do it that often. Part of this not changing the up position was because of all of the possible inferences under the tractor that I could not see. One problem I had as new was that the 2 ac lines that run to the rear were getting molested by the mmm gear box. Some persuasion and zip ties solved that problem. You may want to check your set up. I was never able to adjust the front pivot asmy to the factory dimension. Not enough thread engagement. The 26.9 dimension. All the installation instructions say for clearance to install the mmm is to turn the front wheels full left, mower deck gets installed from right side. That worked for me for both the bar and turf tires. A little tighter on the bar tires. Another thing I do is attach a rope the deck to pull it out and in under the tractor. I am no longer on my hands and knees pushing the deck around. I always 90 deg the rear wheels and detach the front springs. I had trouble lowering the deck to the cut height. It would always change when using the mickey mouse stop setup inside the cab. JD had a fix coming which was only a new heavier cable argt. Still didn't work. I ended up extending the 3 pt. lever arm approx. 5.5 , now about 7.25 inched inches from pivot point and putting in a adjustable mechanical stop. Solved that problem. If you need details for that let me know because I do not know if there was ever any additional fixes from the factory. One other thing that I modified was the zerk on the tensioning arm that is buried under the deck. I added a grease hose and extended the zerk out when is easily accessible, again some more zip ties. Last item is rear wheel spacing. I have the 8 position rear rims and they are set such that the outside of the rear tires are at 72 inches. The mmm is proud on the left side so that you are not cutting grass that has been previously run over with the rear tire. Part of the design I guess. Later.

I let everything go with the 955 other than the Woods 68 inch reverse rotation tiller. The new tractor would eat up the old attachments. The neighbor that I help out across the street has a farm, and he has a 5 and 7 foot brush hog as well as a 12 and 15 foot batwing. We were going to try the 12 footer on the 4720 but we didn't need it just yet.

The farmer who owns the property next to me, bails hay in the fields. I just cut paths around the property other than the dam of a five acre pond. The dam is probably 3/4 of an acre or better. It is also very steep. I felt like I might want a suitcase weight or two on the front on the steeper parts, but the tractor did well. The 955 didn't give me any, I might need to jam reverse feelings. It might be the new higher in the seat cab tractor. Both are hydro. I just cut the dam with the 72" belly mower.

Both main farms are a few miles away next to each other, so I figured I would see what I could do with what I have before I went to pick attachments up to use then drop back off. I will keep the dam mowed now so it wont be an issue. I usually mow the dam every two to three weeks depending on the rain.

They have a 90 hp JD cab tractor, I can't remember the model, that runs the batwings, so we thought the 4720 could do it. The farmer who owns the pond next to my property, would cut the dam with an old school 4320 or 4520 with a 15 foot batwing. It eats up a lot of horsepower mowing tall grass up hill. I had to keep it in mid range 7 mph top speed and I was running about 4.5 to 5 mph up hill. There is a speedo on the E hydro dash. I hope this helps. Once I get the batwing on, I will report how it does. The trails I cut are kept to a minimum, just enough to get a pickup through.

I have an old beat up 42" pull behind brush hog for 4 wheelers that I am planning on mounting vertically to keep the trees at bay at both farms. I saw the idea on the internet. I am going to put a hydro motor on it and I have to reroute the return oil to the sump, so it doesn't overheat the oil. I might go one further and make it so I can cut above too. I spent quite some time with a pole saw making some room for the cab.

I was looking on the John Deere site and saw this today on MMMs.

I知 looking to add mid PTO kit lvb25959 to a 2008 JD 4320. Wondering what was involved with you adding the mid PTO to yours. I知 assuming they would be similar. Thanks!
