Unique Features

The Super Bronco 13a6a1bs066 42 Hydro Riding Lawn Mower Tractor is unique in and of itself, but there are a few extra features that we want to highlight.

Foot-Controlled Hydrostatic Transmission

You’re probably wondering to yourself, “what on earth is hydrostatic transmission?”.

Essentially, Hydrostatic transmission or HST exists when a hydraulic pump is connected to one or more hydraulic Motors and is dedicated to those Motors.

This allows for superior versatility by allowing either or both the motor(s) and the pump to be displaced variably.

The result is a continuously variable transmission or CVT. The hydrostatic transmission on this lawn mower tractor allows you to reach a maximum speed of 5.2 miles an hour.

42-inch Cutting Deck

Normally we wouldn’t list the cutting Deck of a lawn mower as a unique feature, but the Super Bronco 13a6a1bs066 is far from normal.

Most standard push-behind lawn mowers have a maximum cutting Deck size around 22-25 inches.

This lawn mower has a 42 inch cutting Deck. This huge cutting Deck allows you to mow lawns of any size with extreme ease, and it likely won’t take you longer than 10 to 20 minutes to mow a standard household lawn.


Power, Design and Durability


The Super Bronco 13a6a1bs066 42 Hydro Riding Lawn Mower Tractor Has an impressive 547cc Troy bilt engine. If you were planning to tackle hilly and even and challenging terrain then you picked the right lawn mower.

The super bronco will be able to traverse most steep inclines that you might have in your lawn with ease.

It’s wheels are also quite large which gives it a lot of traction, meaning it’s very unlikely that you’ll encounter many issues when trying to mow wet, thick, or tall grass.


The Super Bronco 13a6a1bs066 42 Hydro Riding Lawn Mower Tractor obviously Doesn’t look like your average everyday lawn mower.

Since it’s a tractor lawn mower, there’s a seat on top of the chassis which is where you sit and control the Machine.

The chassis is powder coated to avoid any corrosion and chipping of the paint. The seat can be adjusted and is designed to be as comfortable as possible for longer mowing sessions.

The steering mechanism is also designed to be comfortable and easy to use so that folks who have never used a tractor lawn mower before won’t have a hard time learning how to operate it.


The Super bronco is probably one of the most durable lawn mowers out there. It is specifically designed to be able to tackle rough terrain and tricky mowing conditions.

It’s going to take a lot of wear and tear for you to damage this lawnmower beyond repair.

That being said, there are some standard things that you should never do with any lawn mower, like maneuvering it over concrete, gravel or bricks.

Cut Quality and Available Options

The 42-inch cutting Deck is capable of mowing a large area of grass with each pass on your lawn.

Although the super bronco does come with a side dish charging mechanism there is also a rear bagging and mulching attachment available for purchase as well.

These options are especially useful to folks who have loans with thick grass densities or whose grass gets tall very quickly.

Over the duration of just one summer, Unkempt loans with a thick grass can start to build up thatch on its upper layers.

This can make it much more difficult for water to saturate the roots fully, and could start choking off areas of grass that would otherwise be healthy.

Once this happens you are going to need to fork out the extra cash to buy an aerator, or have your lawn aerated professionally.

Performance and Ease of Usage

The powerful 547cc Troy bilt engine gives you enough torque to Slice through extremely thick and unwieldy grass, while simultaneously applying pressure for the hydrostatic transmission.

At full Throttle the super bronco has a top speed of 5.2 miles an hour.

As with all tractor lawn mowers the super bronco is very noisy, and if you plan on mowing your lawn with it at 7 a.m. on a Saturday, you’ll definitely be waking your neighbours up.

This is a lawn mower that is definitely better suited to larger lawns when neighbours might be in sight but out of earshot.

One of the common complaints that people have when using tractor lawn mowers is the strong vibrations which can cause aching in the hands and legs, as well as the discomfort of sitting in the seat for extended periods.

Triple try to make the Super Bronco as comfortable as possible by allowing you to adjust the seat and designing it with soft cushions.


Ease of Maintenance, Repairs, and Warranty

The standard lawn mower tractor maintenance protocols come into play with the Super Bronco. If you’re going to do the Bare minimum, you will want to Grease the pulley system seasonally, and also perform oil changes routinely.

The electric ignition system on the Super Bronco is known for being somewhat iffy, so you are going to want to keep an eye on it.

Replacement plates can be quite difficult to find, so, if you are able, you should try to purchase replacement blades when you first buy this lawnmower.
