[AT] Deere 4020 oil leak

[Tyler Juranek]

Hi John,
 One thing I've learned over time is that sometimes doing stuff cheap
now will cost more later. If it's been in the family since new, it's
money well spent. I'll bet your dad enjoys the 4020 also.
 I still have the 88 in the shed. A family friend is going to rebuild
the steering in it for me, so that should be good. Grandpa turned 80
this January, and so I think I should make it a long term goal to have
it all done and restored before his 90th. Maybe my back pocket will
feel a little heavier by that time...
 Take Care,
