The Sunstar lawnmower by Simplicity is a powerful machine to have in your garden shed. Its accurate and compact design is best suited for small gardens, lawns, and uneven terrain! Moreover, by using the various attachments provided, you’ll be carrying out landscaping projects like revamping your corner garden area without breaking a sweat.

Let’s take an in-depth look at the features of the Simplicity Sunstar and see what’s in store.

#1. General Features

Simplicity launched the Sunstar series of lawnmowers in the year 1987. They continued to tweak the tractor over the years and released variants in the Sunstar series, such as the Sunstar 16, Sunstar 18, and Sunstar 20. The Simplicity factory is located in Port Washington, Wisconsin, USA. Since then, it has served as the birthplace of the Sunstar from 1987 to 1997. Although the production of this model ceased in 1997, the Simplicity Sunstar gives other modern tractors a run for their money.

There are multiple variants of the Sunstar lawnmower categorized by their deck size. The base variant of the tractor weighs 873 lbs, while the 46-inch deck and 60-inch deck models weigh 1051 lbs and 1108 lbs, respectively.

Compared to modern tractors, this lawnmower is slightly larger, with a wheelbase of 51 inches and a length of 78 inches. What’s best, this elongated design aids in maintaining the center of gravity and keeps the tractor balanced when equipped with light or heavy attachments.

However, a minor drawback of the design is the open operator station. Say you’re working on building a fire pit for your garden and have attached a wheelbarrow attachment to your Simplicity Sunstar to do most of the heavy lifting. Though the tractor is meant for heavy-duty work, there’s a risk of the machine toppling over if the trailer is overloaded. In this event, the open operator station provides zero to no protection for the user.

Furthermore, the Sunstar boasts an 18-inch wide, 22-inch deep, and 18-inch high seat, providing more comfort than most other tractor seats on the market. This makes operating the tractor for lengthy durations pleasant and doesn’t strain the back of the user.

#2. Engine

The Sunstar series of lawnmowers by Simplicity implements a Kohler Magnum gasoline-powered engine. This 2-cylinder engine has a full-pressure lubrication system and maintains its temperature by running an opposed-twin air cooling unit. 

Note: The front end of the lawnmower is covered with a hood, gauges for fuel and electricity are installed on the dashboard.

The gasoline-powered engine on the Sunstar packs a punch and delivers a staggering 20 HP, making hauling of the heavy materials a piece of cake. This extra power permits users to carry out extensive landscaping tasks requiring heavy machinery, such as leveling a sloping yard with ease. What’s more, the parts used in this tractor are highly durable, and with proper maintenance, won’t need to be replaced for years to come. 

Not to forget, a common problem most tractors face is starting during the winters. Many starter motors and sparkplugs have operating temperatures higher than the outside temperature during cold seasons. DIY gardeners and backyard owners should be happy to know the Simplicity Sunstar rarely faces this issue as it houses a Champion RV15YC electric sparkplug capable of operating smoothly at temperatures up to -25 Celsius.

#3. Chassis

Chassis of Simplicity Sunstar

The Simplicity Sunstar has a bulky body mainly due to the powerhouse it hides beneath its hood. A welded steel frame holds the body in place, giving the mower a sturdy appeal. Also, a length of 78 inches and a width of 38.25 inches put this tractor into the medium-sized category.

In addition, this tractor comes with a tray for housing tools and other equipment. Interestingly, some users have fashioned the tray to carry their beverages on the field. With a lawnmower so versatile, the possibilities are endless.

Unfortunately, since the paint used on the Simplicity Sunstar is outdated, it will fade within a few years if kept under harsh sunlight. Remember that you can solve this problem for good by applying a fresh coat of paint to make your Sunstar look as good as new.

The steering wheel is at an adequate height of 47 inches and is placed to make operating the mower comfortable. To top it up, this old-school beast comes equipped with a power steering which makes driving the Sunstar effortless so you can focus on your gardening and farming tasks.

#4. Transmission

The Sunstar hauls enough power to tackle rough jobs and boasts a 20 HP Kohler Magnum engine with a Sunstrand 15 transmission system. This system is the driving force that takes power from the engine and propels the tractor forward.

Above this, the speed of the Simplicity Sunstar is impressive, considering the weight and bulk size. And as the tractor reverses at a speed of 4.5 mph, it moves forward at 8 mph. Most importantly, a 4.25-gallon fuel tank ensures long hours of work without having to refuel in the middle.

Two-foot pedals operate the shaft-driven hydrostatic transmission system on either side of the steering wheel. In addition, the Sunstar implements a 2-range infinite forward and reverse gear system with a 4×2 two-wheel drive. Lastly, the front tires are 16 x 6.50-8 in size, and the rear tires are 26 x 12-12.

#5. Attachments

The Simplicity Sunstar can be equipped with various attachments like a mower deck, blades, snow blowers, loaders, plows, and other ground-engaging tools. Using additional equipment attached to the tractor will take the load off many tedious tasks around the lawn as you aren’t limited to just mowing the grass.

For instance, a 46-inch front-mounted snowblower will change the way you look at your tractor. Likewise, you can go for a 48-inch mower deck, depending on your task. Or, if you feel that’s not adequate, you can switch to a 60-inch mower deck to tackle that gnarly overgrowth in your lawn. Couple this with a 46-inch blade with the option for a hydraulic angle; you’ll have the perfect lawn mower for all your needs.

Simplicity also provides a loader to transport materials using the tractor. Above all, this loader can carry a weight of 480 lbs which makes this a must-have attachment for your Simplicity Sunstar.
