How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A closed center system, while more expensive perhaps, is usually more efficient as it is not continuously sending oil through the valve when it is not being used. Consequently, less energy and less fuel is used – which results in savings on fuel costs.
Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics. Petroleum-based or mineral-based fluids are the most widely used fluids today. These fluids offer a low-cost, high quality, readily available selection.
In an open loop system, the fluid cycles through, returning to the tank at the end of the cycle. There, it loses heat before being cycled through the system again. A closed loop system does not allow for this heat dissipation.
A closed loop circuit can operate smoothly in forward and reverse directions without a directional valve being involved. This eliminates the need for the valve component, which can be costly and take up valuable real estate on mobile equipment. This also cuts down on hose and fitting complexity and space.
Thus, a closed loop (hydrostatic) system offers a way to finely control the speed and direction of a motor. Unlike an open loop hydraulic system, fluid does not flow to a reservoir, but flows directly back to the pump (which is why the term “closed loop” is used to describe this type of circuit).
Hydraulic equipment used indoors under normal service conditions generally use a conventional antiwear hydraulic oil with the appropriate viscosity. The most commonly used viscosities are ISO 32, 46, or 68, since these are able to lubricate and protect the system under the normal range of operating temperatures.
Petroleum-based fluids: Petroleum-based oils,also called mineral oils, are the most widely used fluids in hydraulic systems.
Turbine, compressor, pump, boiler, heat exchangers, etc.. are examples of the open loop hydraulic system. For simple applications, open loop hydraulic systems are efficient and cheaper.
Closed-center circuits supply full pressure to the control valves, whether any valves are actuated or not. The pumps vary their flow rate, pumping very little hydraulic fluid until the operator actuates a valve. The valve`s spool, therefore, doesn`t need an opencenter return path to tank.
A disadvantage of the open loop circuit design is its relatively large size and weight due to the large volume of oil required. In a closed loop circuit design a single hydraulic pump is used to drive one or more hydraulic motors.
There are many types of hydraulic motors, but the most efficient type is a rotary vane motor. This type of motor uses a series of vanes to turn the rotor, which in turn produces mechanical power.

Dont know what type of oil to use – Toro Power Lawn Mower
ANSWER : Put straight 30 weight motor oil in it. Not 10W30 or any multi-viscosity oil. Straight 30 weight motor oil. If you’re doing a complete oil change, then you may want to use Synthetic 30 weight, which will last longer between oil changes and also make your engine last longer (but it costs more too). Best of luck to you.James

My husky 455 rancher is not oiling the chain properly. I have tried to clean all the oil ports on the bar and saw but it still is hardly pumping any oil to the chain. What could be the problem? How does the oiling system work?
ANSWER : The problem is very likely to be a clogged but more likely faulty internal oil pump (especially if your chainsaw is old).Hope it helps.

What kind of oil in the oil tank and how much for the remington electric pole saw ?
ANSWER : Bar & chain oil is the best. You can use regular or synthetic. Some say you can use atf (auto transmission fluid) or sae30 oil. I use bar & chain oil.

I have a husqvarna 137 chainsaw. The problem is with the bar oil. When the saw runs oil is flowing but where the rubber corner piece which allows the oil to flow out of appears to be just dripping the oil straight out. It looks like it should fill a small reservoir behind the metal plate and the oil then moves upwards where the chains drags the oil through the oil hole on the bar which is moving outwards as in the top chain on the bar. However the chain-brake area is just getting messy with oil splattering all over and the bar not actually getting oiled. I have fitted a new metal plate to see if the corner of the original was not sealing properly but that has not helped. The bar holes are clean. Any suggestions as I can’t see what it could be?
ANSWER : It’s the rubbers. I had the same problem with my 137 and 141. The rubbers shrink over time and the oil never makes it up the channel. The replacement part is one piece and less prone to leaking than the original 2 piece design.

Ms 170 leaks bar chain oil out bottom, no oil on chain
ANSWER : Your clutch drum bearing has gone bad, letting the clutch drum to move around and cut into the oiler behind it, so now it just pumps the oil out that hole. You have to get that fixed to use the saw, otherwise you’re going to cause catastrophic damage to the saw very soon.
