Well.... anyone here familiar with the 755? Or JD's in general? I see this one for sale on the side of the road. He doesn't know what year it is, but they made them from 1986 to 1999. It's 4WD hydromatic. Snowblower & front bucket come with it. All JD stuff. Three cylinder Yanmar diesel. My one big question is: It has 6,000 hours on it. That seems like a lot to me! At that number, is it about ready for a rebuild? New engine? Or is it about ready for another 4,000 hours before an usual issues?

He's asking 7K, but said he'd come down some. I know green stuff is expensive, but I'm thinking 5 grand is a much better price. But, if 6,000 hours is near the end of the life of the engine, then it aint worth $5 to me! :)

Thanks for any info.

Depends what you want to do with it. If it's mowing then the Deere x534 is in a class all of it's own with the 54" deck. I spent $7K new and I have a Hustler 400, 4,6,8, 15ft bush hogs/batwings and I have not even connected them this year yet. If it's exotic plowing/snow removal/PTO stuff then that's something else. Are you sure you need all that other stuff? I tremble to think what a new 755 engine would cost and perhaps Deere might just tell you they are now obsolete like my AMT600 and I can't even source the parts. Of course the x534 has other stuff too but I don't use it for that.

I have a zero turn for lawn mowing. This would be A: front bucket use for the wife & her yard work. B: snow removal, and C: Bush hog on the back to mow the back field once a year.

<edit> Oh! And.... PTO for emergency generator use.

If I got this JD I could sell the Kubota that we only use for bush hogging and I could sell the Wheelhorse that is only used for snow removal and I could sell the old Wheelhorse that is only used for...ahhh... not quite sure what but the wife won't let me sell it. She can't drive the Kubota, but she could drive the JD.

That seems like a lot of hrs for the price. That is only my opinion though. A friend of mine sold one with around 2000hrs for 7k about 5yrs ago.

just for the numbers...i have a 1987 wheel horse, only used to mow3 acres every week since new and its hour meter has 906 hrs on it. so mee thinks either it was a commercial use machine or hr meter had a issue...

6k hrs is quite a bit on the yanmar . its past its dependable use in my book. not to be confused with worn out but I would freshen it up with valve job, rings,mains and rods and oil pump. cooling system and fuel system clean out front to back.

if you could do a compression test thru the glow plug hole and a op test....... injection pump rebuilders could offer thier insight as to when they puke :idea: :idea:

It is due for a rebuild I am afraid. We always figured 5000 hours, but on a Yanmar...I am surprised it actually made it to 6000 hours. I know a lot of lobster boats have had problems with their Yanmar's, but marine engines are slightly different.

The hydro drive can be good/bad. It is nice for loader work since you can just go from forward to reverse with ease, and without shifting, BUT on field work like bushogging, it can be a problem. We had a slosh drive 8830 Ford tractor and while the powershift feature was nice, when plowing you could not sink the plow deep enough and get enough speed to get the sod to roll off the moldboard. The tranny would get hot and so your gear selection was not done so much by what gear you set it in, but by the temperature of the tranny. I wanted to run in 9th gear, but it would only take 8th for any length of time. That was no good.

7 grand also seems steep. Our little Kubota with 2000 hours on it books for $8200 so while green does fetch more, $1200 dollars less, with 3 times the hours seems suspect to me.

I have a 595X with the yanmar. If I remember correctly It cost me 13K with a 54 inch mower deck in 2005 or 2006, so 5 grand doesn't sound too far off with all of the goodies.

6000 hours over twenty five years is only 240 hours a year. That's not beat or run hard if you ask me.

My dad has a Yanmar 12kw genny with close to 10,000 hours, it runs every day without any issues. He has kept up on the maintenance but nothing out of the ordinary.

Agreed, the hrs would not bother me if it was serviced properly & not beat on. BUT--the guy, you say doesn't even know what year it is--I wonder what he knows of it's past?????? :(

My old genset ran 10,000 hours and was running fine when it was replaced. It was a yanmar, most diesel gensets are rated for 30,000 hours, clean oil, fuel and air they will go a long time. But thats chucking along at 1800 RPM, tractors are a bit different and Fred makes a good point.

From what I've heard, the 755 was particularly vunerable to worn hubs and drive shafts on the front. I have two friends that had the same problem.

vast difference in longevity between a drag racer and a taxi cab....both have the same engine but one is going pretty much the same speed every day... the other is trying to spit the timing gears from the on throttle off throttle mashing

a stationary powerplant unit will go oddles of hours with minor maintenance

hogging snow or dirt with a loader is where the "end play" of the crank gets wide...... ;)

if its a 99 then 9 hrs a week, every week for 14 yrs prolly comercial unit....
if its a 86 then 5 hrs a week, every week for 26 yrs..... grass cuttter /snow plower

Thanks for all the input. I CAN get the serial number & that will tell us what year it is. I guess for now it sits like this in my head. IF I decide to look further into it I will certainly not pay more than 5K for it....maybe start at $3,500 and talk, and... I'll see about compression check & talk to the dealer about what else to do to verify it.

Wow .. here I am thinking I paid a ridiculous amount of money for a lawn tractor ...you guys got me smoked by a mile there! It did cost more than the truck I drove it home with though. :lol:

I guess the X-series stands for X-SPENSIVE ... :D

Here's my lowly G-series. I thought I was livin' large here! Thanks for the wakeup call .... :lol:

I just read a couple of weeks ago in “WALKER TALK” that for commercial mowers the rule of thumb that many go by is 100 hrs. times the horsepower for air cooled engines and 150 hrs. times the horsepower for liquid cooled engines. At that point it makes sense to rebuild or replace the engine. By this formula that 755 has twice those hours but commercial mowing services are looking to replace or rebuild before the engine is shot, at a point just before reliability becomes an issue.
