Fix Your Hydrostatic Transmission Problems Fast

Combustion engines, like those found in most cars, transfer power to the vehicle’s axle, which turns the wheels. Hydrostatic transmissions found in most modern tractors and zero-turn mowers, work by transferring power from the engine to hydraulic pumps which use liquid pressure to move the wheels. There’s no need for gears, and changing speed is smooth and efficient.

With any transmission, things can go wrong. The first step is to read your Operator’s Manual. There are many different types of equipment with hydrostatic transmissions, and we can only offer general advice. Your tractor operator’s manual will have information specific to your make and model, and will offer helpful information about where to find filters and other parts that might require servicing are located on your tractor or lawn equipment.

Where to find more information:

Hydrostatic transmissions include mechanical parts such as a differential and a drive axle, plus rubber or metal hoses the liquid is pushed through. Failure of any mechanical component, a broken hose, or clogged filter will cause tractor hydrostatic transmission problems. But the most common issue will be the oil itself.

In the transmission section of your operator’s manual, you’ll find a section that covers oil viscosity. Here’s an example from a John Deere manual. Note that, while temperature affects viscosity, the right oil has enough range to operate in any reasonable weather.

Here are some basic troubleshooting tips to fix your hydrostatic transmission lawn tractor problem fast!

Zero-Turn Mowers: Purge Your Hydraulic Drive System

Zero turn hydrostatic transmission problems can start with air in the system, a condition known as cavitation. When the pump is full of air instead of oil, it can’t generate the pressure needed to provide power. This is pretty common in zero-turn mower transmissions. After your mower has been stored for the winter, it’s a good idea to purge the transmission before use. It’s also a good first step if your motor is sluggish or slow.

NOTE: If your mower or tractor has a transmission that must be removed for service, be sure to purge after it is serviced and before you use it.

• Park the mower on level ground, set the parking brake, and put the rear on jackstands.
• Make sure the oil reservoir is properly filled according to specs.
• Disengage the transmission (check your operators manual to see how this is done).
• Sit in the operators seat and start the engine.
• With the engine running, move throttle control to slow position. Position the motion control levers in neutral (N) and disengage clutch/brake pedal.
• Push motion control levers forward all the way and hold for five seconds.
• Pull motion control levers to full reverse position and hold for five seconds.
• Repeat steps 6 and 7 three times. This purges any air from the hydraulic transmission system.
• Put the control levers in neutral (N). Shut the engine off and set the parking brake.
• Check the oil and top off if necessary.
• Engage transmission.
• Remove from jackstands, start the engine, and disengage the brake.
• Move control levers forward and roll about 5 feet. Then slowly reverse about the same distance. Return the levers to neutral and repeat this steps three times.

You’re done! The air is purged from your system and your zero-turn mower is ready for action.

Check The System

If your system is purged and you still have a problem, it’s time to do a little basic troubleshooting. Start with a complete visual check of the hydraulic system.

• Check the oil level and add oil if needed.
• Inspect the hoses and connections for damage or signs of leaks.
• Clean pump cooling fins with a rag, brush, or compressed air, and check for damage.

Change Your Hydraulic and Steering Fluids

Sluggish operation is often due to old or overused fluids. If there are no signs of fluid leaks or damage, it may be time to change your hydraulic and steering fluids.

Hire An Expert Troubleshooter

If you need help troubleshooting your tractor’s hydraulic system, call your dealer. Their service department should be able to ask the right questions, give suggestions, and you can make an appointment for service if necessary.

Riding mowers are a popular mower choice for homeowners, especially if you have a big property to maintain every summer. They have cutting decks measuring from 42 to 72 inches, so you can make short work of everything from typical lawns to large properties, like sports complexes and golf courses.

Unlike their push mower counterparts, riding mowers have more features to consider in order to find the right fit for your yard. You can choose either a manual or hydrostatic transmission, so you can set and forget your speed or operate your mower like a car. You can even get riding mowers with cruise control or all-wheel drive for better traction.

While gas engines are far more common among riding mowers, there is a wide selection of battery-powered models if you’re looking for a more eco-friendly solution for lawn care. My pick for the best overall riding mower is the Troy-Bilt Super Bronco XP for its 24HP engine, 54-inch cutting deck, and ability to mow up to four acres with a full gas tank. You can keep reading below to find out more about the Troy-Bilt Super Bronco XP as well as our other top picks.

Ryobi 80V electric riding lawn tractor

Which is the right riding mower for you?

Other than your budget, there are a lot of features and scenarios you have to consider while shopping for a new riding mower. The size of your yard will determine how wide the cutting deck should be, though either a 42 or 46-inch version will be more than enough for most yards.

You can choose either a manual or hydrostatic transmission. A manual model lets you set and forget your speed so you can FOCUS, while hydrostatic models operate more like cars, going faster the harder you press the pedal. This makes them more intuitive to operate but also more expensive.

Zero-turn mowers are designed for mowing in oddly-shaped areas or around lots of obstacles like trees, lamp posts, and lawn ornaments. They’re called zero-turn because they have a zero-inch turn radius; you pivot around either rear wheel for ultra-tight turning.

How did we choose these riding mowers?

I used to work for MTD Products (now owned by BlackDecker), which assembles a variety of lawn mowers, snow blowers, and other powered lawn equipment. Using the expertise and knowledge I gained during my time there, I looked for riding mowers with these qualities:

• Motor size: You’ll want a riding mower with at least a 10HP engine to give you enough power to handle minor inclines and lawns up to half an acre. Larger riding mowers like the John Deere Z530M have more powerful engines, often topping out over 20HP to let you tackle rough terrain and even haul equipment.
• Cutting width: Many riding mowers have either a 42 or 46-inch cutting deck, which is great for lawns between.5 and 1.5 acres. However, if you have a large, multi-acre property, you’ll want to choose a larger cutting deck. Many brands have options between 50 and 72-inch cutting decks.
• Transmission type: The less expensive riding mowers will have either a 6 or 7-speed manual transmission. This means you will use a dedicated lever to set your engine’s forward and reverse speeds, with a single brake pedal for stop control. The more expensive models feature a hydrostatic drive, which operates in a similar way to an automatic transmission in a typical car or truck.
• Accessories: Lawn care goes beyond regular mowing. I chose riding mowers that have the ability to hitch small trailers or wagons for hauling tools, mulch, or potting soil. I also chose mowers from brands that make after-market add-ons, like rear bagging units for collecting grass clippings, mulching kits for re-feeding lawns, and snow plows for year-round use.

How do you decide which riding mower to buy?

Assuming you have a budget in mind, the first thing you need to do is find out how big your lawn is. You can either find your lot size on your memorandum deeds if you’ve bought your house, or you can check your city’s website to see if you can request lot measurements if you’re renting. If your lot measures about an acre, you’ll be able to use a 30 or 42-inch cutting deck without any issues. For lawns up to two acres, a 42 or 46-inch deck is ideal. And if your lot is over two acres, you can get a mower with up to a 72-inch cutting deck to handle larger areas.

The transmission type is also important. Many newer models have what is known as a hydrostatic drive. This means that they operate similarly to how a car drives: You push the pedal and it moves forward or backward. And the harder you push, the faster you go. This makes it easier to learn how to drive, but that also makes the mower more expensive. stripped-back models have variable speed manual transmissions, which allow you to set and forget your speed so you can FOCUS on paying attention to obstacles and people who may be nearby.

And finally, you’ll want to consider the power source for your new riding mower. Gasoline engines are far more common, but there is now a wider variety of battery-powered models to choose from. The perks of a gas engine are that you’ll get near-infinite run times (as long as you have enough fuel to keep the engine going) and a bit more power for handling steep inclines and rough terrain. The downsides are dealing with exhaust emissions and maintenance that can be a time and money sink. Electric models don’t need engine maintenance, so you save a bit of money in the long run. But they usually have a maximum run time of about an hour, which means that you may have to plan your mowing over several days if you have a larger yard.

How big of a yard do I need for a riding mower?

Riding mowers are best suited for yards measuring one acre or larger. A model with a 42-inch cutting deck is great for mowing up to two acres, so if you have more land than that, you’ll want to spring for a 46, 54, 60, or 72-inch cutting deck.

If you’re right on the threshold, you can get what’s known as a mini rider. They usually have compact bodies for easier storage and 30-inch cutting decks to make short work of lawns that are just a touch too large for a push mower.

How long should a riding mower last?

No matter if you choose a gas or battery-powered riding mower, proper maintenance is key to extending the life of your mower. For gas engines, you should change the oil and filters, clean the spark plugs, and sharpen the blades before you mow for the first time in the spring. And you should use fuel treatments like STA-BIL to prevent gas in the tank or extra jerry cans from going bad from moisture contamination. This prevents buildup of gunk that can ruin your engine, improves engine performance, and gives you a cleaner cut for a healthier lawn.

Electric mowers don’t need engine maintenance, but you should perform thorough inspections at the start of mowing season to check for battery damage, corrosion on battery contacts, damage to the battery housing, and also to sharpen the blades. If you do regular maintenance, not only will you save money by avoiding big repairs from worn-out parts, but you can also expect your riding mower to last 10 years or more.- which is great news, since they can be an expensive investment.

What is the cheapest riding mower?

Unfortunately, riding mowers aren’t ever really what we consider budget-friendly. However, there are models like the Murray MT100 that retail for less than 2000 without sacrificing power or cutting width.

Are there alternative riding mowers worth considering?

Whether you’re shopping at a big-name DIY store like Lowe’s, a local hardware store, or an authorized brand dealer, there are tons of options for a new riding mower. You can choose either gas or battery-powered models, cutting deck widths from as small as 30 inches to as wide as six feet.

Here’s a short list of other riding mowers I thought were great choices:

John Deere Z530M

The John Deere Z530M features a 60-inch cutting deck for making quick work of large properties. Exceptional maneuverability lets you mow around trees, lawn decor, and other obstacles with ease.

Husqvarna YTH1942

The Husqvarna YTH1942 features an updated, 19 horsepower engine and 42-inch cutting deck to take on inclines and haul dirt, mulch, and gardening equipment.

Murray MT100

For under 2000, you’ll get a 13.5 horsepower engine, a 42-inch cutting deck, and a 6-speed manual transmission with the Murray MT100.
