Bosch Rotak 37 Review

If you have a small to medium sized lawn, then an electric lawn mower may be the perfect purchase in order to keep your lawn looking neat and tidy all year long. There is no reason to busy yourself with a cumbersome petrol lawn mower if you have a lawn and garden that are both on the smaller side.

Choosing the perfect mower for your particular household and lawn can be a daunting task for even the most seasoned DIY experts. There are a few aspects to consider before making this rather large purchase.

Corded vs. Cordless

There are two types of electric lawnmowers: corded ones and cordless ones. Cordless mowers are powered with rechargeable lithium ion batteries and corded mowers are plugged into wall sockets with an extension cable. Whichever model you choose, you can rest easy knowing that these types lawnmowers are much more cost effective and environmentally friendly than petrol powered lawnmowers are.

With proper care and maintenance, these mower can last for up to ten years. This period of time can be extended even longer with a sizable warranty from the seller. If you take proper care of the blades, keep your mower off of wet ground, and keep all of the components tightly wound, your mower should last for years.

Lawn Size

The size of your lawn will determine which kind of lawn mower will best suit your needs. If you have a very small area of grass that needs cutting, then a manual push mower will suit your needs just fine. With this type of model, the mowing blades are mounted into a cylinder that revolves in a circle when pushed by the operator. Although there is no modern power source for this type of mower, it is extremely simpleto use. Rotary mowers elicit a clean, precise cut to any patch of grass and allow you to easily manoeuvre around obstacles and edges as well. In addition to these benefits, push rotary mowers take up very little storage space as well.

If you have a medium sized lawn, than an electric lawn mower will do the trick for you. Electric mowers either are powered through a cable plugged into a power socket or with rechargeable lithium ion batteries. These lawn mowers usually come with a handy grass box to collect clippings and garden debris. Most corded electric mowers do come with a rather short cord, however, so if you go with this type of device, make room in your budget for purchase of an extension cable.

  • Cut right up to the edge of your lawn with grass combs and integrated rear roller

Mower Features

Modern lawn mowers come with a host of incredible features that may or may not benefit you and your household. The more features a mower has, however, the more expensive it will be. It is best to pick and choose which mower features you absolutely must have on your new device so you do not break the bank once your make your purchase.

A good mower will have an option to adjust the mowing height. This is an important feature because at different times of year, it is healthier for your grass to be at different lengths. For example, at the beginning of the year and during dry weather, it is always a good idea to leave the grass longer so it does not get too stressed. At the start of the summer around the month of May, you are going to want to cut your grass shorter so it stays neat and polished for longer.

Most good mowing products allow the operator to adjust the height of the blade cut between a set range of heights. Some models allow you to change the cut height by simply moving one lever, while other ones let you adjust the height of each wheel.

The starting mechanism on mowers is another feature to be considered before buying. Most petrol powered lawnmowers are started by with a pull cord. If you are looking for a product that is more simple to start up, then keep electric and and battery powered mowers in mind.

Adjustable handles are an added feature that do not come on every lawnmower. Although this is a more rare feature to find, it is a handy one nonetheless. While some mowers have fixed length handles, other models will allow you to adjust the handles among a range of heights. If the handles are situated at a fixed height, then make sure that they handles are at a comfortable height for you, especially if you are taller or shorter than average. Adjustable handles also make it easier to store away your lawnmower. Some models have handles that can be folded down all the way into the body of the mower to completely hide them away. If you have a lot of edges to your patch of grass or a lot of obstacles to mow around, then consider buying a mower that allows the operator to get up close and personal to garden edges.

Some, but not all lawnmowers include a rear roller to give your lawn that professional striped finish. If this is important to you, then make sure your next electric lawnmower includes this feature. A rear roller is a great addition to any lawnmower if you want to give your grass a sharp cut and professional finish. A good rear roller will be on the heavier side, so a lawnmower with an integrated rear roller will tend to be a bit heavier than other models. Also, this particular feature tends to increase the price of any lawnmower, so budget may play a factor when thinking about all of these things.

A grass box is a vital feature on most mowers that can make or break your garden or DIY product. A grass box allows the operator to collect grass clippings as it is cut so that your lawn is given a clean and crisp finish. A high quality grass box makes cutting grass and overall more pleasant and pleasurable experience.

Propulsion Method

Many modern day lawnmowers are self propelled. Self propelled lawnmowers are handy in that they drive themselves. While they still need guidance from an operator, self propelled mowers are easier to use as they weight does not all fall on the burden of the operator.

There are electric models of lawnmowers that are not self propelled, but are manually powered instead. Push models of lawnmowers tend to be more inexpensive than self propelled models are. They do not have a gearbox and are more suited to smaller, level lawns that do not house many obstacles or awkward areas.

Self propelled mowers feature a gearbox and travel by themselves by way of the operator holding down a lever on the handle bar of the mower. They can come with one speed or variable speeds; it all depends on the make and model of the mower. Self propelled mowers are better suited for larger patches of grass that may even have a slope to them. They are also very helpful for operators that may have mobility issues or tire easily from yard work. Self propelled mowers help to cut down on user fatigue and muscle strain.

Types of Mowers

There are so many different types of mowers on the market today that choosing one to buy can be an overwhelming experience.

A cylinder mower is able to cut grass by employing the circular motion of cylindrical blades; this type of lawnmower gives a neat cut to grass and allows the operator to give their garden a professional looking finish. If you plan to meticulously manicure your lawn on a regular basis, then a cylinder mower is just the ticket. Some models even allow attachment of a grass collection box to make clipping disposal so easy.

A rotary mower utilises blades that rotate horizontally which works well with all grass types, even tougher varieties and weeds. These mowers are usually on the cheaper end of the budget spectrum, so if you are on a tight budget, it is worth taking a look that this variety. These mowers usually have an option to attach a collection box to ensure that collection of garden debris a breeze.

A hover lawnmower is a more modern model of mower that really brings gardening into the 21st century. Hover lawnmowers create a cushion of air using fans to hang over the grass. If you have a small patch of grass to cut that has some hard to reach areas, then a hover lawnmower is a great purchase. This model is perfect for someone who wants to cut grass both forwards and backwards. Make sure you only buy this kind of lawnmower if you are less concerned with the quality of the cutting of the mower and more interested in buying a cheap tool that will get the job done.

Electric lawn mowers come in corded and cordless varieties. A cordless lawnmower is perfect for a person who wants the power of a petrol lawnmower but with the ease and simplicity of using an electric lawnmower. These models are lightweight and simple to start. They have sharp blades that require little to no maintenance and use a basic powersource that you will already have in your home.

Bosch claims that the grass collection box collects up to 99 percent of all the grass clippings as well.

The handles on the Bosch Rotak 37 Ergoflex are ergonomically designed, hence the 'Ergoflex' part of the mower's name. The Ergoflex handles are adjustable and multi-functional which are features that allow the operator to maintain better body posture and reduce muscle strain and fatigue.
