Hydrostatic

Wife has been whining about how the big mower with hydrostatic
transmission has been slower the last couple years :P. I
usually wait till the drive belt wears out aka breaks till I
replace.
After she used the other mower to finish her sections the other
day ( aka big rider broken blade ) she really noticed it and the
whine got alittle louder. ;D
I was looking at some belts I had in the barn and came inside to
look the numbers up. Dag nab if one of them didnt come back to
be a brand new drive belt for the big mower. :'( I must have
bought one in years past to have just in case it broke.
So being caught up on stuff. I pulled the deck and got to it.
:-X :-X :-X :-X :-X
Put the new drive belt on and told the wife to see what she
thinks. IMO it hadnt helped any as far as speed :-X :-\. The
other belt was showing signs of wear though.
Well I parked it and wrote it off.
I couldnt leave well enough alone so I started searching for
adjustments for Hydrostatic Transmissions.
Hydrostatic Transmission Ground Speed Adjustment - Riding Mowers
NOTE: These instructions are prepared for use by trained
technicians who are experienced in the service and repair of
equipment of the kind described in this publication, and are not
intended for use by untrained or inexperienced individuals. Such
individuals should seek the assistance of an authorized service
center. Please visit our Authorized Service Center Directory to
make arrangements with a service provider in your area.
Hydrostatic transmissions feature control rod linkage from the
speed control lever (or foot pedal on some models) to the
hydrostatic transmission. This control rod connects to the
hydrostatic transmission at a regulator valve, which determines
the rate of fluid flow through the transmission and the output
speed to the wheels. This regulated travel limits the range of
the transmission valve. These control rods are adjustable. By
rotating the threaded linkage connector ferrules, the length and
the resulting range of movement at the regulator valve can be
altered. Please refer to the tractor Operator's Manual and
associated parts diagrams for more information on the location
and identification of these linkages on a particular model/style
of tractor.
If the control valve is adjusted to maximum position (either
forward or reverse) and the ground speed still seems slow, then
the transmission may need internal service. Internal bypass
valves may need to be inspected and low fluid levels, fluid
contamination or clogged filters corrected to return the
transmission to peak operating performance. Please visit our
Authorized Service Center Directory to make arrangements with a
service provider in your area to have your equipment serviced.
Did the adjustments and she :-X :o now. Told speedy dont wreck
the dang thing. ;D :D

Guy that brought in the partner chainsaw. Was complaining of his
hydrostatic slowing up over the years.
I just smiled. Told him get his model number and go to makers
website for info the way I learned. I also told him about the
above I found on mine on how to do it.
