I do hope im posting this in the right section. I bought a John Deere riding lawnmower. I hate it!!! from the moment the thing was delivered. I also bought the dump trailer, i hate it to...I bought it to so i can load it with horse poo and i would be able to dump it, to bad i have to shovel it out! Now tomorrow i plan on going to Lowes and telling them to come pick up this piece of (word not allow on answers).
Now my question is what mower should i look at buying? I have a Murray and the thing is well over 10 years old and still running and can out run the John Deere. I have looked at Husqvarna and the Craftman. Would like some help here before i lose my mind....Thanks ") I will be shopping tomorrow and would like to pick a new one up then.
I do use it for mowing and for towing. I have 22 acres. Wanted something to perform both functions.
Answer
I suppose that you're using the small trailer designed to carry 800 lbs. If so when buying your new mower buy a garden tractor series which has the transmission capable of towing that weight. Lawn tractors are able to pull themselves and the rider and that's about it. Yardman (MTD) has a garden tractor series and so do many others. Husqvarna is made by MTD now but I don't remember seeing a garden tractor series. I could be wrong. Craftsman are way too expensive. Sears way of telling their customers that they appreciate their business. Many people have been stung by that John Deere junk so don't feel bad. Nothing manufactured today is what is used to be nor what it should be.

what's is the difference between hydrostatic and regular transmission on riding lawn mowers?

Answer
Basically the hydro has the ability to change directions on a dime without having to stop and manually reverse the tranny. This accounts for better maneuverability and braking power. They provide continual torquing power as well... This excerpt below was taken from hydraulicspneumatics.com and explains the advantages quite well. Here it is......
........The primary function of any hydrostatic transmission (HST) is to accept rotary power from a prime mover (usually an internal combustion engine) having specific operating characteristics and transmit that energy to a load having its own operating characteristics. In the process, the HST generally must regulate speed, torque, power, or, in some cases, direction of rotation. Depending on its configuration, the HST can drive a load from full speed in one direction to full speed in the opposite direction, with infinite variation of speed between the two maximums - all with the prime mover operating at constant speed.
The operating principle of HSTs is simple: a pump, connected to the prime mover, generates flow to drive a hydraulic motor, which is connected to the load. If the displacement of the pump and motor are fixed, the HST simply acts as a gearbox to transmit power from the prime mover to the load. The overwhelming majority of HSTs, however, use a variable-displacement pump, motor, or both - so that speed, torque, or power can be regulated.
HSTs offer many important advantages over other forms of power transmission. Depending on its configuration, an HST:
transmits high power in a compact size
exhibits low inertia
operates efficiently over a wide range of torque-to-speed ratios
maintains controlled speed (even in reverse) regardless of load, within design limits
maintains a preset speed accurately against driving or braking loads
can transmit power from a single prime mover to multiple locations, even if position and orientation of the locations changes
can remain stalled and undamaged under full load at low power loss
does not creep at zero speed
provides faster response than mechanical or electromechanical transmissions of comparable rating, and
can provide dynamic braking.
