Lawn Tractor Transmission Types

The fives types are gear, friction disk, automatic, CVT, and hydrostatic.  I'll spend a couple of minutes dealing with each kind so you've a much better idea of the greatest type for you personally. I'm not entering the particulars of methods each one of these works.  Just Google the transmission type and you may read for your heart's content.

Gear

5 years ago the apparatus drive transmission was typically the most popular however nowadays hydrostatic and automatic transmissions have changed them in recognition. Frequently known as Manual transmissions this kind uses a number of gears to alter the floor speed of the tractor.  The greatest downfall of this kind of transmission is you need to steer clear of the tractor to change to a new speed (range).  This means they are harder to make use of if you have lots of garden beds and landscape features for everyone.

They are driving the tractor you have to push in around the clutch, change the transmission towards the gear you need to use, release the clutch, and hang up on.  This is really a reliable  transmission that provides you with many years of service.

Friction Disk

This really is really the transmission of preference for snow blowers but you will find a couple of lawn mowers such as the Snapper Rear Engine Driver which use this trans.  It is a great, reliable transmission when used correctly.  It utilizes a friction wheel and disk to alter the forward speed of the driver.  Don't make use of this transmission to drag heavy loads...you'll tear in the friction wheel.

You are able to change-on-the-opt for some models but to obtain the longest existence most brands suggest you push lower around the clutch/brake pedal after which change towards the speed you would like.

Automatic

This really is basically a belt and variable lever system like the drive system inside a snowmobile.  John Deere initially used this along with a stick shift around the Model 110.  Now days, MTD is applying this of all of it's least expensive lawn trucks. Such as the friction disk this trans is made to the mower application and they're not made to pull heavy loads.  Some from the Brands have confused the problem by calling their affordable hydrostatic trans an "automatic" so if you're unsure request.

They are driving the tractor you generally have two levers.  One for forward or reverse and also the other for that speed. Slowly move the F/R lever towards the direction you need to go after which simply move a fender mounted lever to alter the rate. This can be a reliable  transmission that provides you with many years of service for flat grass and tugging very light loads.

CVT/IVT (Continuously/Infinitely Variable Transmission)

The automated pointed out above and also the hydrostatic here are basically CVT's  but nowadays what this means is a flexible disk or ball/disk system.  This may be the transmission for the future since it uses less moving parts than the usual gear trans and fewer oil than the usual hydrostatic, but at this era they're not reasonable to lawn tractor programs.  MTD attempted while using dual IVT Infinitrak within the Cub Cadet and Builder Revolution but customers weren't prepared to spend the additional money to possess this kind of transmission. New Holland is applying these effectively within their 50 hewlett packard and bigger trucks.

These transmissions are extremely simple to use.  Either a fender mounted lever or feet control varies the rate and direction.

Hydrostatic

The most typical transmission for lawn trucks today is really a form of Continuously variable transmission known as the hydrostatic transmission. These transmissions take several forms, from pumps driving separate motors, which might add a gear reduction, to completely integrated (enclosed) models that contains a pump, motor and equipment reduction.  Hydrostatic transmissions tend to be more costly than mechanical transmissions but they're simpler to make use of and may transmit greater torque towards the wheels as in comparison to some typical mechanical transmission.

Hydrostatic - Enclosed Single

These transmissions are extremely simple to use.  Either a fender mounted lever or feet control varies the rate and direction.  The enclosed hydrostatic transmission is really a single unit that houses the variable pump, motor, differential and drive axle.  Most of lawn trucks, yard trucks, garden trucks and estate trucks today come with an aluminum housing to produce the warmth the moving oil produces.  These transmissions are sized towards the mower application.  The garden tractor and estate tractor transmissions are made to deal with heavy loads and ground engaging accessories.

These transmissions are extremely simple to use.  Either a fender mounted lever or feet control varies the rate and direction.  The pedal around the left side from the tractor may be the parking brake.  You don't need to depress that pedal to change the tractor.   The forward and reverse is controlled by whether lever around the right fender or two pedals around the right side floorboard.  To move forward push the fender lever forward or press around the large pedal on the ground board.  To steer clear of the tractor pull the lever to the center position or raise your feet from the pedal.  To back the tractor up pull the fender lever towards the rear or press the little pedal around the floorboard.

Around the fender mounted control you need to slowly move the lever towards the middle to prevent your tractor.  It will not go near neutral alone such as the feet controls.

Hydrostatic - Enclosed Dual

Two hydrostatic transmissions are mounted side-by-side within the residential zero turns.  Each trans controls another rear wheel.  That is the main reason why zero-turn lawn mowers are more expensive compared to lawn trucks. Again these trans are equipped for the applying and many are not shipped to drag loads, just mow and bag.

Many of these transmissions are controlled by individual levers that sit before you.  With just a little practice they are very simple to use.  A large lever on both sides from the chair controls that side transmission.  To move forward push on levers.  To stop, pull it well.  (The simplest method to let you know that they are driving a 2-lever zero turn mower would be to  use a shopping cart software for example.  With the mower switched off take a seat on the chair and set their hands on the 2 large levers before you.  Close you eyes and pretend you're gripping a shopping cart software.   Where do you turn to maneuver a shopping cart software forward? Right, you push around the handle.   To support? Right, you withdraw around the handle.  To go left?  To go right?  Correct, you PUSH the handle within the direction you need to turn the trolley.  Two lever zero turns work exactly the same way.  Instead of 1 bar just like a shopping  cart, the bar is split in 2 and also you move both sides to really make it move.)  This kind of transmission takes practice to help keep the tires from digging to your lawn.

Hydrostatic -Pump & Motor

The greater costly commercial zero-turn lawn mowers, stand-ons, plus some course lawn mowers make use of a separate variable pump close to the motor attached to the wheel motors with hydraulic hose or metal lines.  These are often surefire for lengthy existence and sturdiness. A couple of from the high-finish commercial lawn mowers are actually using enclosed surefire hydros.
