Agricultural Implements

Rotary Tillers are machines used for both primary and secondary Tillage for cultivating the soil. They use a series of blades that eliminate weeds, relieve compaction, as it mixes and levels the soil. This agricultural equipment is very powerful and is used for seedbed preparation.

Size – The size of the tiller you should buy must be relative to the garden and soil you have as follows:
Garden size – if your patch is only a few metres square then using a small 1.5 Hp tiller should do the job (power wise) easily enough providing the soil is ok (more about soil below). Also, in a small area you don't want a large machine with big wheels as turning and changing direction in a small space could be problematic. Likewise, a large area to be cultivated would obviously be faster with a wider tiller base (500-700mm) otherwise you'll be walking behind your machine all day using a tiller only 24cm wide.
Soil – Is your soil hard as buggery or soft and sandy? It's important to understand your soil type as the purchase of a tiller can really go wrong in this area and lead to great disappointment. An undersized, underpowered tiller will just skip across the surface of a hard clay-based or rocky compressed patch of dirt and hardly not dig at all. Even worse, the forcing downwards to compensate and make it dig may lead to damaged tines, broken hubs, snapped gear shaft etc, or even injury! Wet clay will just stick to the undercarriage of the machine and clog the tines rendering an inferior tiller useless, whereas, a more powerful tiller (say 6.5 Hp or more) can keep turning and throwing the clay/heavy soil out. The opposite can be said for light sandy or already well cultivated soils where a smaller or less powerful tiller/rotary hoe could save considerable cost, be easier to manoeuvre, and do as good of a job as a large expensive more powerful machine but you must know your soil qualities first before deciding.

Motor – Many of these tillers/rotary hoes come with similar designs and exteriors; however, it's inside that makes all the difference and the motor obviously is important. These machines are placed under incredible stress for long operating periods and whilst the cheaper motors will do the job for awhile it's prudent to get a machine with a good brand name. These companies protect their reputation by constantly reviewing, testing, and upgrading their products with warranties and claims usually well managed. Plus, you're buying a tiller to do a tough job and you deserve confidence in the make that it will do the task as advertised – the last thing you want is to waste time replacing machinery or chasing a warranty claim through a company on the other side of the world with support staff who don't care.

Reputable retailer – L guess there's no problem with trying one of those “no-name” brands of tillers/rotary hoes as long as you get them from a retailer with a fair exchange or money back policy. You'll get your money back if the tiller breaks or doesn't live up to expectations; it may be a bit of a stuff around but at least your covered. At the end of the day, flexibility and peace of mind is what a good retailer gives so I'd stick with a retailer you know or one with excellent reviews (especially if you are trying a brand that isn't very well known).

Cost and quality – I've heard of people buying cheap chainsaws that last about 18 months before they throw it and buy another. They swear this method is cheaper in the long run compared with buying an expensive brand. Each to their own, although, I tend to take the view cheaper in most cases means inferior parts, which logically must affect performance – I would think. Performance is especially true for tillers. I've even had a conversation with a sales person at a popular hardware store where he has discreetly discouraged me from buying any of their several tillers saying the warranty returns for them are high due to breakdown and poor results – now that's what I call standing behind the product you sell from a proper hardware store. If you want my advice, go for a quality brand product but research and seek the best possible price because prices fluctuate greatly in tillers/rotary hoes.

Lawn Mowing Implement
A lawn mower and trimmer both have a motor and engine. They have different components for performing the required task.
The lawn mower has blades while lawn trimmers have a line for trimming the grass. The blades cut the grass while the line of the trimmers is used for trimming the grass.

Shape and Size
A lawn trimmer is generally smaller in size compared to a lawn mower. A mower has a bigger motor and more components than a trimmer. As a result, the trimmer has a bigger body as compared to lawn trimmers.

Function

• The lawn mower is used to cut the height of the grass. The mower cuts about 95 percent of the grass height. In contrast, a trimmer is more of a detailing tool. The function of the trimmer is to trim the grass at tight corners that cannot be reached using a mower.
• Mower coverage is much more as compared to the trimmer. You can mow larger areas of lawn using a mower. The trimmers are not suitable for mowing the entire lawn.
• The mower is designed to do most of the heavy work in cutting the lawn. In contrast, a trimmer is used for removing the leftover grass from the lawn.

Size of the Grass
A mower will let you cut the grass to the exact height you want. You can use a push mower or riding mower to cut the grass. These mowers have blades underneath that rotate when you mow the lawn.
