When you first get your new diesel mower, or your gas mower, you may be surprised to find out that you need to buy a hydraulic power unit. This is something that you really should consider carefully, because if you choose the wrong one, you could end up wasting money on a mower that doesn’t work right. Hydraulic motors and drives have been around for a long time, but they just haven’t been popular in the past few years. Now, however, there are lots of companies making high-performance drives and motors for garden equipment, and some of them are even offering a hydraulic power unit that fits directly onto the spindle of your existing drive.
Gas and electric motors are a different matter. They both have a very flat torque-rate curve, so they both deliver about the same torque in top speed as they do in low speed, which means that a hydraulic power unit, like the ones from https://www.hydraproducts.co.uk/Hydraulic-Power-Units, with an electric motor of some sort will usually need a gas or diesel engine of a higher power rating to operate at its best. The problem here is that you get what you pay for, and the more powerful the motor, the more expensive it will be.
One thing that many people don’t think about, is how to maintain the pressure in their hydraulic system. It’s usually best to use water or oil to keep the system well-maintained. There are several things that can go wrong with a hydraulic system, ranging from a low water level in the reservoir to a clogged drain line. In order to prevent problems in this area, and to make sure that your new unit is giving you the best performance possible, you’ll want to install a high quality water reservoir and drain lines. You can even buy special self-cleaning systems to help keep things cleaner.
