Experienced gardeners share their insights in answering this question :
This can be a loose belt that is slipping, low fluid in the transaxle, a bad pump (if hydrostatic transaxle) or worn gears, start by checking belt tension, then replace the fluid and filling to proper level, if that fails, the trans will need to be inspected for internal damage to pump and gears
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Mowers mostly use two types of transmissions – gear driven and hydro-static. The gear-driven type is very basic, the common manual lawn tractor transmission (the manual type usually called a gearbox) will have 5 forward gears and one reverse.
Three primary transmission systems are used in riding mowers and the various classes of mowing tractors. Mower decks are designed to operate at a constant speed – typically full engine speed. This means adjustments in vehicle speed have to come from the transmission, not by varying the engine speed.
Powered by a 125cc OHV Briggs & Stratton engine, this Yard Machines push mower is ideal to quickly tackle small yards with minimal obstacles.
Continuously variable transmissions (CVTs) are a step up from geared transmissions and are available in two styles. The less expensive designs have a foot pedal to control speed and a manual shift lever to change from forward to reverse. The higher-priced CVT models don`t use a shifter.
Hydrostatic CVT
Hydrostatic Continuously Variable Transmission is a type of CVT that uses a variable displacement pump and a hydraulic motor. In the new Geared HCVT, the energy is transferred by means of a hydraulic fluid.
CVT Technology from ZF
Almost all renowned tractor manufacturers use continuously variable transmissions from ZF. In particular, their reliability, efficiency and ease of operation are highly regarded on the market.
In tasks such as moving manure or compost, hydrostatic transmissions are preferred due to their ability to switch from forward to reverse instantly. A second positive is that you can control the speed and direction of travel with your foot, leaving your hands free to focus on steering and operating the tractor loader.
Yes, a riding lawn mower typically has a clutch. This clutch is used to engage the engine with the transmission, allowing the mower to move forward at different speeds.
While a hydrostatic transmission vs manual uses a hydraulic motor and fluid, manual transmission tractors use a gear box. The number of gears can vary, but a clutch is required to change speed and direction to a different gear.
A 4-Stroke engine is the kind of engine that is common on lawn mowers.

Since 1958 when the first lawn mower rolled off the line, MTD has been designing easy-to-use outdoor power equipment and building a reputation for quality and dependability second to none. Yard Machines® provides the equipment you need to get yard work done.
Most lawn mowers are powered by four-cylinder engines, but some walk-behind lawn mowers use two-cylinder engines. Four-cylinder engines are typically more efficient and eco-friendly, compared to two-cylinder engines.
With CVT the engine output is transferred via the torque converter. The torque converter is configured with an ATF and along with working like a clutch, is an important vehicle part for increasing torque and transferring powerful kinetic force when moving off.
A Continuously Variable Transmission (CVT) does not use gears like a typical automatic transmission. Rather, it makes use of 2 pulleys connected by a belt. It`s a bit like a snowmobile transmission: One pulley attaches to the engine, the other pulley to the transmission. The belt moves the power in between them.
A CVT doesn`t use any gears at all. Instead, they rely on two cone-shaped pulleys to transfer power from the engine, through the transmission, and to the drive wheels.
The continuously variable transmission is called CVT transmission for short. The CVT transmission, which can provide stepless speed regulation, is especially preferred by Japanese automobile manufacturers. For this reason, it is also called the Japanese gearbox.
CVT technology dates to before the turn of the last century, but its first production use by a mainstream automaker in the U.S. was in the Subaru Justy subcompact in the late 1980s. These days, Subaru is all-in on CVTs, while Honda, Nissan and Mitsubishi also use them widely across their lineups.
Why CVTs and Diesel engines don`t mix. CVTs rely on the friction between the two cones and the belt between them to deliver power to the wheels. Overpowering this friction will lead to losses in terms of power delivery.
In tasks such as moving manure or compost, hydrostatic transmissions are preferred due to their ability to switch from forward to reverse instantly. A second positive is that you can control the speed and direction of travel with your foot, leaving your hands free to focus on steering and operating the tractor loader.
A hydrostatic transmission uses hydraulic fluid to power the wheels. A gear drive transmission uses gears and a clutch to deliver power from the transmission to the drivetrain. The automatic transmission tractor form is hydrostatic.
They are filled with the specified pump fluid to match each pump design and then sealed by each manufacturer at their factories. Replacing hydrostatic fluid is normally not necessary, unless the drive system is in need of some other internal service or repair.

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.
Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!

Left the electric lawn mower in the rain this winter thinking it was like the gas one. Will not hold a charge. How do we fix?
ANSWER : If you are not mechanically inclined, You may want to seek the help of your local mower shop. However, If you can take the top off. Make sure you make a diagram of the wiring or a picture before you take any thing apart. Take the batteries out and get them load tested. If you have a Battery Plus in your area, You may be able to get new batteries from them.
