Very late to this thread... but, I've seen this posted before and elsewhere.
It would be very helpful for other users/buyers to have a look see at his problem.
I'd like to have a gander at what the defective axle leak, breakage looks like.
I've used my JD 110 as a machine... not a toy or yard ornament, too. Nary a problem.
Just yesterday I moved, pushed and leveled nearly 200 yards of pit-run fill for my pole barn extensions. Started at 6:00am with 2, 12-yard trucks running from the pit @ 15 minute intervals.
That tractor was "humpin"!
Not a direct "apples vs apples" comparison, I know. But, Deere knows how to build good, reliable, hard-working machines. The 4720 should be able to do 5 hours of landscaping work without blowing an axle seal!
