The fives types are gear, friction disk, automatic, CVT, as well as hydrostatic. I’ll spend a few minutes going through each type so you have a better idea of the best type for you. I am not going into the details of how each one works. Just Google the transmission type as well as you can read to your heart’s content.
several years ago the gear drive transmission was the most common although today hydrostatic as well as automatic transmissions have replaced them in popularity. Often called Manual transmissions This particular type uses a series of gears to change the ground speed of your tractor. The biggest downfall of This particular type of transmission will be you have to stop the tractor to shift to a different speed (range). This particular makes them harder to use when you have a lot of garden beds as well as landscape features to go around.
To drive the tractor you must push in on the clutch, shift the transmission to the gear you want to use, Discharge the clutch, as well as hang on. This particular will be a dependable transmission that will will give you years of service.
This particular will be actually the transmission of choice for snow blowers although there are a few mowers like the Snapper Rear Engine Rider that will use This particular trans. the idea will be a Great, dependable transmission when used properly. the idea uses a friction wheel as well as disk to change the forward speed of your rider. Don’t use This particular transmission to pull heavy loads…you will tear up the friction wheel.
You can shift-on-the-go with some versions although to get the longest life most brands suggest you push down on the clutch/brake pedal as well as then shift to the speed you want.
This particular will be essentially a belt as well as variable pulley system similar to the drive system in a snowmobile. John Deere originally used This particular in conjunction having a manual transmission on the type 110. currently days, MTD will be using This particular on most of the idea’s cheapest lawn tractors. Like the friction disk This particular trans will be designed to the mower application as well as they are not designed to pull heavy loads. Some of the Brands have confused the issue by calling their inexpensive hydrostatic trans an “automatic” so if you are unsure ask.
To drive the tractor you typically have two levers. One for forward or reverse as well as the different for the speed. Move the F/R lever to the direction you want to go as well as then simply move a fender mounted lever to change the speed. This particular will be a dependable transmission that will will give you years of service for flat lawns as well as pulling very light loads.
CVT/IVT (Continuously/Infinitely Variable Transmission)
The automatic mentioned above as well as the hydrostatic below are essentially CVT’s although currently days This particular means a variable disk or ball/disk system. This particular will be the transmission of the future because the idea uses fewer moving parts than a gear trans as well as less oil than a hydrostatic, although at This particular point in time they are not yet cost effective for lawn tractor applications. MTD tried using the dual IVT Infinitrak inside Cub Cadet as well as Craftsman Revolution although consumers were not ready to spend the extra money to own This particular type of transmission. brand-new Holland will be using these effectively in their 50 hp as well as larger tractors.
These transmissions are very easy to use. Either a fender mounted lever or foot control varies the speed as well as direction.
The most common transmission for lawn tractors today will be a form of Continuously variable transmission called the hydrostatic transmission. These transmissions take several forms, via pumps driving separate motors, which may incorporate a gear reduction, to fully integrated (enclosed) units containing a pump, motor as well as gear reduction. Hydrostatic transmissions are more expensive than mechanical transmissions although they are easier to use as well as can transmit greater torque to the wheels as compared to a typical mechanical transmission.
Hydrostatic – Enclosed Single
These transmissions are very easy to use. Either a fender mounted lever or foot control varies the speed as well as direction. The enclosed hydrostatic transmission will be an individual unit that will houses the variable pump, motor, differential as well as drive axle. Most of lawn tractors, yard tractors, garden tractors as well as estate tractors today have an aluminum housing to give off the heat the moving oil creates. These transmissions are sized to the mower application. The garden tractor as well as estate tractor transmissions are built to handle heavy loads as well as ground engaging attachments.
These transmissions are very easy to use. Either a fender mounted lever or foot control varies the speed as well as direction. The pedal on the left side of the tractor will be the parking brake. You do not need to depress that will pedal to shift the tractor. The forward as well as reverse will be controlled by either a lever on the right fender or two pedals on the right side floorboard. To go forward push the fender lever forward or press on the large pedal on the floor board. To stop the tractor pull the lever back to the middle position or lift your foot off the pedal. To back the tractor up pull the fender lever to the rear or press the modest pedal on the floorboard.
On the fender mounted control you HAVE to move the lever to the middle to stop your tractor. the idea will not go to neutral by itself like the foot controls.
Hydrostatic – Enclosed Dual
Two hydrostatic transmissions are mounted side-by-side inside residential zero turns. Each trans controls a separate rear wheel. that will will be the primary reason why zero-turn mowers cost more than the lawn tractors. Again these trans are designed for the application as well as most are not designed to pull loads, just mow as well as bag.
Most of these transmissions are controlled by individual levers that will sit in front of you. having a little practice these are very easy to use. A large lever on each side of the seat controls that will side transmission. To go forward push on BOTH levers. To stop, pull them back. (The easiest way to explain how to drive a two-lever zero turn mower will be to use a shopping cart as an example. With the mower turned off sit on the seat as well as put your hands on the two large levers in front of you. Close you eyes as well as pretend you are gripping a shopping cart. What do you do to move a shopping cart forward? Right, you push on the handle. To back up? Right, you pull back on the handle. To go left? To go right? Correct, you PUSH the handle inside direction you want to turn the cart. Two lever zero turns work the same way. Instead of one bar like a shopping cart, the bar will be split in two as well as you move each side to make the idea move.) This particular type of transmission takes practice to keep the tires via digging into your lawn.
Hydrostatic -Pump & Motor
The more expensive commercial zero-turn mowers, stand-ons, as well as some golf course mowers use a separate variable pump near the motor connected to the wheel motors with hydraulic hose or metal lines. These are usually cast iron for long life as well as durability. A few of the high-end commercial mowers are currently using enclosed cast iron hydros.
