Garden tractors 101:

First, all power created on gas garden tractors is created by 2 things:
1) change in elevation such as going up or down hills
2) the gasoline engine

Second, the gasoline engines are designed to operate at constant speeds
determined by two things:
1) the governor on the engine
2) the tension the throttle lever applies to the governor-spring.

Third, three things determine the speed of a tractor:
1) the speed of the engine
2) the gear ratio of the transaxle
3) the drive tire diameter

Fourth, there are two types of transaxles:
1) mechanical
2) hydrostatic

Either type of transaxle just ratios of the number of revolutions of the
engine to the number of revolutions of the rear wheels, nothing more and
nothing less. However, in doing so the torque available to the rear
wheels is changed, but all power comes from the engine and the torque is
determined by the ratio and not the type of unit. Hydrostatic units
have more power loss due to more heat generation.

The advantage of the mechanical is that the ratios are predetermined by
the gears and are reproducible.

The advantage of the hydrostatic is that the ratio is infinitely
variable.

They hydrostatic usually costs more and is sometimes called automatic,
but it isn't automatic. It usually has forward and reverse pedals and
usually a cruise lever. The mechanical transmission has a clutch and a
shift lever.

People who use automatic transmissions usually like the fact the
hydrostatic transaxles don't have a clutch.

In the manual for the John Deere OMM149664, Issue L3 Lawn Tractors
LX280, LX280AWS, and LX289 PIN, automatic transmission tractors it
specifically says:

"Do not use cruise control when going down hills. Machine speed will
increase."


Then don't use cruise control when going down hills. I don't have cruise
control on my hydrostatic tractor and it actually brakes when going down
hill, as long as I take my foot off the pedal.

That means you have to keep your foot on the "forward pedal" like a
throttle when going down hills.


And that would be a means to brake the mower? What about the brake
pedal, or is that not mentioned? In a car, the brake pedal will
disengage the cruise control, does that not happen with a tractor.
I don't have cruise control, so you will have to enlighten me. I'll take
your expertise opinion on this.

With a gear-shift transmission you go up and down hill without touching
any levers or pedals. Their speed doesn't increase going down hills.
They are much safer.

Did you ever own a hydrostatic tractor, or are you just going by some
pre-conceived assumption?
After all, as you said, you have a lawn as flat as a billiard table,
never have to back up, and use only a single forward gear, so how would
you know about hills, braking, and backing up?

Wrong. My Murray hydrostatic drive will go into a braking mode when I
lift my foot off the pedal going downhill.

Are you saying that John Deere manual does not describe operation of
Murray tractors? You are correct. But I doubt that John Deere is
wrong, they are talking about their own tractors.

I'm sorry. I was referring to hydrostatic operation while going
downhill. My comment was not about cruise control (which I do not have),
but about hydrostatic operation when going downhill. But you would know
much better about hydrostatic transmissions and cruise control since you
own neither. I deleted that message and composed another, if you would
care to comment on that one.

What the hell does cruise control have to do with a hydrostatic being
worse or better than a gear model......seems like your grabing staws
that are totally irrevelant to the original posts concerning the
hydrostatic drives............

And I suppose a manual shift tranny with cruise will not gain any
additional speed either.....duh!

As does my GX335 as soon as I let off the go pedal it slows and
stops...........but just think if you had a manual you cold keep on
coasting and save fuel!
I sure don;t know where S.M H, gets his info or how he cyphers out
what he reads but he needs to put a brighter light bulb in his reading
lamp.............and get up to date on hydrostatic drives and garden
tractors.

He is just grabbing at straws randomly, and the post is getting so far
off its original matter, mainly due to the fact of S.M.H's ignorance

Methinks that Hemmings knowledge of lawn tractors is limited to those
which he owns, as well as as the lawns of which he is familiar with.
There can be no other variations.

I know. I'm just letting him dig a bigger hole. At some point, we will
never hear from him again, or he will say that it's not so bad down here
in the hole, or he will ask for help getting out of the hole. I'm having
fun, you?
