Gravely 8122

Still on the hunt for a good mower. Came across a gravely 8122. Don't know a thing about them. Appears to be an early 80's model, 12hp kohler, 8 speed trans, 4 low/high, 42 inch deck. It looks good in the pics, appears to have never seen rain. Says it has brand new clutches, set of chains, and extra set if blades, and is asking $1200. Seems a little high but again, I'm don't know a thing about these. Parts still available?? How's that 12hp kohler on power?? Thanks.
 
We had a 8123, traded it off in the early 90's. It had plenty of power from the Kohler, wich was trouble free aside from normal tune-up parts.

I believe I replaced the traction clutches once during the time we owned it. That job takes about 30 minutes as they are located externally, one on each side of the transmission.

The only thing I didn't like about it was the reverse speed. It seems like HI on the range shifter gave you a very slow reverse and LO gave a fast reverse. That kind of defeated the idea of the hand clutch being an efficient means of switching directions as you ALSO really needed to shift the range lever to obtain a more suitable reverse speed.
 
12 HP I going to seem very under powered by todays standard. Mowing speeds have increased so the HP requirements have increased too.

The Gravely mowers hold up well but do you have dealers around you??? There is none within 50 miles of me.

I actually do have one Gravely dealer about 30 minutes away. I'm going to look at it and a JD lx188 with 42 inch deck. It looks excellent and the guy said $1000 was bottom dollar on it. I honestly don't know which route to go.
 
Mowing speeds haven't increased on the yards that I mow. They are just as rough today as they were 30 years ago and my arse tends to vacate the seat if I speed up !

Hydrostatic drive is a power robbing convenience though, and most mowers of today have it as standard equipment.

The mower in question does not have hydro, nor does it have hydraulic lift.

I would encourage Casey to test the mower if possible to conclude if power is going to be an issue for his needs.
 
If you are doing any amount of mowing, get a machine with hydrostatic or hydraulic drive. It is so much superior to mechanical drive for mowing and trimming
 
I believe that engine has been discontinued, at least that is what I was told. Also told that only one engine that could be used as a replacement and that was a 20 hp onan. I have no idea if this is true or not. The engine mounts directly to the cast iron trans axle. I do know these are very heavy tractors and are prone to leaving tracks on soft turf. That aside the one I have does very well on fairly rough ground. Like all wider units it will scalp at times. It has a none synchronized trans and care is needed when shifting, just takes a minute. I use mine for everything from the lawn to bush hogging corn stalks in the garden. It has better staying power than the 15 hp briggs in my sons Craftsman tractor used in the same setting, its a 12 hp kohler.
 
For what it's worth, I have 3 Gravelys, oldest one is 42 and the youngest is 38, I wouldn't have anything else. Parts are expensive, but I've put very few parts on these units.
