Testing Brush Mowers & Land clearing Equipment in Extreme Conditions

What happens here

This step delves into the two main types of drive systems for brush mowers: right-angle drive (also referred to as 'right drive') and direct drive. Shane explains that Quick Attach utilizes both, but strategically. For smaller mowers where maintaining a higher tip speed is crucial, they employ a right-angle drive system. This system incorporates a 2:1 speed increaser, which allows the use of a larger displacement hydraulic motor. Shane highlights that larger displacement motors are more efficient as they avoid the issue of 'breathing through a straw' — where smaller motors are forced to push too much flow, leading to overheating and premature wear. Conversely, while direct drive systems might seem simpler, they spin the disc slower, resulting in less energy. Manufacturers often compensate for this by using heavier blade carriers to achieve comparable energy output. The key takeaway is that the 'strongest' option isn't always the 'right' option; the optimal drive system depends on the specific mower size and intended application, and is chosen to complement the machine's hydraulic flow requirements without causing overheating.

Goal: Differentiate between right-angle and direct drive systems and their applications.

and go up from there as well so let's do this thing this is this is kind of like your go-to model yep right here if we call this the brush buster okay most skid steers out on the market they're either small to medium sized because of the most economical most people aren't using them in contracting type you know jobs they're using and on the weekends or whatnot so the most common skid steers are let's say medium sized right and so we are focused on the medium sized skid steers is right here especially the brush Buster model but now there's direct drive motors there is right drive Moors it even call the right drive yeah we call them right angle drives so we got a couple examples here and you guys use both right yeah right so on our smaller mores where we're trying to maintain a higher tip speed we're using a right angle drive because we can use a two-to-one speed increase there inside of here so okay that's big because it allows you to use a larger displacement hydraulic motor and the reason we do that is because some of these skid steers you have to be able to meet the flow requirements of the skid steer itself without overheating okay and you know if you use a really small motor like you might have to on a direct drive then it's like breathing through a straw it's just pushing so much flow through that tiny little motor that things get hotter they overwork and they're gonna wear out quicker okay so here's the thing if I'm understanding this right inside the industry a lot of companies are trying to push direct drive only as if it's the new technology and it's a stronger version but if I'm listening to you it's not always the right choice it's gotta be the right choice for the right more right great okay we have a saying around here is more than one way to skin a cat and so you can use a direct drive and you can spin that disk slower but you're gonna have less energy because of the speed now a lot of times they'll make up the difference by using a heavier blade carrier so you can either have high speed with a lower mass or you can have low speed with a higher mass and come out with similar types of energy okay horsepower at the spindle if you know what I mean but is there conditions that you would want one yes or the other yes okay so most people are gonna move brush and grass in general they might wish that they could mow a 10 inch tree and and these mowers you can take down a 10 inch tree usually you don't want to do that all day as this is not the tool…
