For a standard household lawn mower under normal conditions, it is recommended to sharpen the blades twice a mowing season. It’s important to keep the blades sharp as they cut grass faster and cleaner, and this cleaner cut promotes faster lawn regrowth. If you notice decreased performance, uneven cutting patterns, or it is taking longer to mow your lawn, it might be time to check the blade. Take the mower to a certified blade sharpener.
The make and model category is further divided into the purpose in which a driver sits on the machine and drives it, and the other where the operator works alongside the vehicle. The type of drive is further broken down to wheel type and track type. The wheel type is then broken down into two, three, and four-wheel types of drives, while the track type is subdivided into full and half-track types of drives.
Hydraulic excavators usually couple engine power to (commonly) three hydraulic pumps rather than to mechanical drivetrains. The two main pumps supply oil at high pressure (up to 5000 psi) for the arms, swing motor, track motors and accessories while the third is a lower pressure (~700 psi) pump for pilot control of the spool valves; this third circuit allows for reduced physical effort when operating the controls. Generally, the 3 pumps used in excavators consist of 2 variable displacement piston pumps and a gear pump. The arrangement of the pumps in the excavator unit changes with different manufacturers using different formats.
Skid Steer loaders offer great versatility. Due to their compact size and zero-radius turning circle, it is possible to use them in confined spaces where many other types of heavy machinery cannot reach. They are ideal for landscaping in parks and yards, or moving earth around a construction site; and in some cases it is possible to use them in place of a full-scale excavator to dig holes. Sellers on eBay also offer specialized buckets and attachments for clearing snow, grinding tree stumps, mowing grass, or digging trenches. With so many practical applications, skid steer loaders represent an excellent investment for small businesses looking to streamline some of their methods and improve overall workforce efficiency, and they are also useful for homeowners or farmers with a lot of land to maintain.
The main types of lawnmowers are the walk-behind mowers (push reel, gas or electric); riding (the fun one), hover mowers, which are push mowers that use an impeller system to push air down, allowing it to hover over the grass; and the robotic mower, which is an autonomous, self-guided unit that is as efficient at cutting the grass as it is at impressing (or frightening) the neighbors.
A tractor is a large, heavy duty vehicle with a petrol or diesel motor delivering high torque at a low speed. Tractors are especially indispensable in the world of agriculture, as they can tow implement or machine attachments used for ploughing, tilling, harrowing, planting and feeding, as well as spraying fertilizers and pesticides. Another popular attachment is the hey tedder that allows haymaking. Tractors also have the power to haul large items, and the heavy treads of their rear tyres allow plenty of traction on soft or uneven terrain. The more modern RC tractors can be controlled remotely and some are used to mow like a tractor mower.

A zero-turn lawn mower is a riding mower that has a zero-turn radius--meaning it spins as opposed to turning like a standard vehicle with front-wheel turning. Basically, these things can turn on a dime. Instead of a steering wheel, most models have levers to control speed to each drive wheel, using a hydraulic-based system. They are considered faster and more efficient than standard riding lawn mowers. Because of this unique feature, they can be more expensive.
Skid-steer loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and where the left-side drive wheels can be driven independently of the right-side drive wheels. The wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. Turning is accomplished by differential steering, in which the left and right wheel pairs are operated at different speeds, and the machine turns by skidding or dragging its fixed-orientation wheels across the ground. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. As with tracked vehicles, the high ground friction produced by skid steers can rip up soft or fragile road surfaces. They can be converted to low ground friction by using specially designed wheels such as the Mecanum wheel. Skid-steer loaders are capable of zero-radius, "pirouette" turning, which makes them extremely maneuverable and valuable for applications that require a compact, agile loader. Skid-steer loaders are sometimes equipped with tracks instead of the wheels, and such a vehicle is known as a multi-terrain loader.
There are two main types of "Control" configuration generally use in excavators to control the boom and bucket, both of which spread the four main digging controls between two x-y joysticks. This allows a skilled operator to control all four functions simultaneously. The most popular configuration in the US is the SAE controls configuration while in other parts of the world, the ISO control configuration is more common. Some manufacturers such as Takeuchi have switches that allow the operator to select which control configuration to use.
Komatsu hydraulic excavators are world class excavators built with the highest quality materials and superior craftsmanship. Komatsu excavators withstand some of the toughest working conditions due to unique casting designs and world class manufacturing processes. With up to six machine working modes, Komatsu excavators produce fast cycle times, effortless multifunction motions, precise bucket movements, and excellent lifting capabilities. Komatsu designs cabs with the operator in mind to provide the best and most comfortable cab environment available.
The original skid-steer loader arms were designed using a hinge at the rear of the machine to pivot the loader arm up into the air in an arc that swings up over the top of the operator. This design tends to limit the usable height to how long the loader arm is and the height of that pivot point. In the raised position the front of the loader arm moves towards the rear of the machine, requiring the operator to move extremely close to or press up against the side of a tall container or other transport vehicle to get the bucket close enough to dump accurately. At the highest arm positions the bucket may overflow the rear of the bucket and spill directly onto the top of the machine's cab.
I called my pal, Kyle, who runs Van Galder Family Farms in Alpine, New York, and my friend and mechanic Bill Phelps, of Phelps Auto in Lansing, New York. I told them what I was up to and they gave me a punch list of things to look at. Kyle, I found out, would be at the auction and could kick tires with me. That night before the auction, I typed out the accompanying checklist of things to look at before the bidding started.
