(ET) New E20 owner

["Markus Lorch" <mlorch vt edu>]

Dear fellow ET owners,

I am proud to announce that I now own a nice E20 with 
mower deck, snow/dozer blade, and WH rear lift and tiller. 

The machine was in working order when I got it. I could 
drive and it only took a little TLC  before I could
mow mine and my neighbor's lawn.

Its great. I love it. I spend the whole day mowing and
working on it.  

I have two questions to which I can't find conclusive
answers on the list/net.

Mowing full speed in D2 or D1 is too fast for my lawn 
as it has bumps and many obstacles to go around. I mowed
today in L. Do you think its better to one of the higher
gears (ampere meter does usually stay in yellow) and
not go with full throttle or to mow in the L gear 
(I have the impression the ampere meter shows lower 
current at roughly same speed when using L).

Also I checked the oil level in my gearbox and it is 
too low. What oil should I use? I would like to quiet
the gears also a little bit. Can somebody tell me
the type of oil/grease I should get? 

Thank you guys

Markus
