Going to look at a 630 tomorrow

I am going to look at a JD 630 tomorrow. This will be the first time Ive looked at buying a 2 cylinder (or any) Deere. I have owned a Farmall M in the past, and currently have an Allis B, so I have an idea of what to expect in an older machine, but Im curious if there are any specific things to watch out for when I go check out this 630.

I have always liked the looks and the sounds of these Deeres. I want to use it for brush and pasture mowing here on the farm, as well as pulling a float in the occasional parade, and just putt-putting around the farm. Currently I am doing all of my mowing with a Kubota B7100HST, which is painfully undersized, with all of 16 HP.

Any helpful input is greatly appreciated! Thanks!
 
With the engine off put the pto in the on
position. Then start the engine. Engage
the pto With the foot pedal make sure it
turns on. Then disengage the foot pedal
and see if it stops turning. If it
doesn't you have some pto work to do.
Same with the hydraulics turn dial on the
governor to on when tractor is off, then
start engine and check for leaks on the
back end.
 
Good advice from Craig.

I like to take a 9/16" wrench along to remove the fill level plugs for the pto & also for the transmission. If the pto is over full, it might be because of a failed seal allowing gear lube to contaminate the pto clutch.

An over full transmission could indicate a failed crankshaft seal allowing engine oil into the first reduction/transmission area.

A "wet" look under the nose could indicate problems in the power steering.

All of these issues are fixable.

I have had a 630 for 45 years. Good old tractors.
 
Hand clutch should snap crisply into and out of engaged position. Power steering
should turn evenly fully both ways. On mine, the one foot brake drags a little
bit.Good tractor, I have manuals if you need some specs. Good luck with your
purchase.

How much trouble is it to fix either the failed crank seal or failed trans seal?
Thanks!
 
Both repairs at first look are a little scary for a non-mechanic like me, but like all repairs, it is done one piece at a time. The pto seal repair will require removing the entire rockshaft assembly. It's heavy, so you'll need a hoist of some sort. Once you get into the pto, you can expect the project to grow into replacing some of the pto brake and clutch parts too.

The crankshaft seal requires removing the right brake, the clutch pulley and related parts, the first reduction gear cover, the pto drive gear and surely several other parts that I have forgotten about. You might have to move the right wheel enough for the clutch pulley to be removed.

Keep in mind - there is no certainty that you will find these problems on the tractor that you're interested in.
 
I loved my 630 It is not a modern tractor though, even with 3pt hydraulics power steering etc. Brakes leave something to be desired. but it is a fun tractor,if the pto is
good it will be a great bush hog tractor with weights on the front.
