We always want more, right? When your 48 inch mower deck starts seeming small, here's the mower deck for ya!

Actually, with no point of reference, you can't tell how big it is. So here it is next to a cub 48" deck...

It's a 72 inch John Deere deck I am refurbishing for a friend. No, it's not for a GT! Originally came off a 935 front mount mower, but the owner is planning to convert it to a 3 point finish mower. Thought y'all might get a kick out of seeing it.

 

The thing is a beast! Even with the mounts, spindles and hardware off of it, just the shell is too heavy to move by one person. I've been moving it around with the tractor loader.

 

My job is to weld up some cracks, move the mounts and scalping wheels around for the new configuration, change the mount for the new transmission and sandblast and paint.

 

One more picture - this is the DECK belt - the belt that runs between the spindles and the transmision - the mower is shaft drive to the pto, so no belt there. Comparing it to a fairly heavy belt off a GT midmount. Considering GT belts (from Deere) go for $30 or more, I would hate to think what this big belt would cost!

just a question for you what's the drive RPM from the front mount shaft.The rear will probably be 540 so you'll have to make sure the RPM'S once mounted to the rear will run the mower properly.Looking forward to the modification.Larry

Actually, the wider the deck, the BETTER cut you get on rough terrain!!

 

I mowed with a 44", then 60", now 72".

The 72" gives far superior results. It kind of bridges across lawn imperfections, and the cut looks like a pool table.

 

This deck weighs 560 pounds!!  :loosing_it:  Do not try to pick it up!!

Larry, the pto on the front mount is 2400 rpm - a weird unique speed since most big tractor mid pto's are at 2100 rpm and rear ptos are either 540 or 1000 rpm.

 

You switch the whole transmission (the right angle drive on top of the mower that the pto shaft hooks to) to one from a 540 application. The transmission mount is different as well, since the front mount faces the pto shaft to the back, and a rear pto faces the shaft to the front. the gear change happens inside the transmission. I don't know the whole story, but he got the deck cheap somehow. Big finish mowers are expensive - even with the rework, he figures to come out ahead on the cost.

 

Alc, I have a 5 foot mid mount mower on my 2320. Some of my property is pretty bumpy - over time, the deck flattens the high spots out!!!

I ran a JD 1445 with a 72" deck on it while on the grounds crew in sem.  Between the Yanmar and 6' of cut one could some serious grass.
