Thank you!
It's there anyone that makes a smaller one for 1.5t mini ex?
I would like to run this unit on a yanmar vio-35.
@briancouslin7194 that machine unfortunately is too light. You'd want a VIO-45 or larger. Appreciate your interest, though!
Hello, my excavator is a takechui tb135. I think the aux circuit makes 19 gpm at 3000 psi. Will this cutter work for me?
Sorry, that is too light for the XBC. We recommend an operating weight of 8900+ lbs. You'd want a TB 240 or bigger.
Buenas tardes...q pasa si hay en el campo piedras..?...q equipo se necesita...graciad
Skeleton rock grapple, maybe? Or a skeleton rock bucket.

You don't need to maximize torque on a rotary cutter. You need speed much much more if you're wanting performance. 22 gpm or less and direct drive has inferior performance to a gear box multiplier setup. Also two blades is far more efficient for cutting than 3-4. Adding additional blades = nothing more than power consumption for minimal gains in mulching performance.
Speed and torque play crucial roles in cutting performance. There’s definitely a sweet spot between the two. Torque is influenced by hydraulic motor displacement and operating pressure, with higher pressure resulting in increased torque. Torque is the way to measure the rotational force the cutter can produce. Greater torque allows quicker spin-up, faster recovery, less chance of bogging down in tall grass and thick material and higher overall productivity. It's also important to consider hydraulic efficiency and heat generation.
Gearbox drive systems exhibit lower efficiency and generate more heat due to friction than Geroler drive systems. The resulting wear and tear, combined with the 10-20% efficiency drop from a Geroler motor, can lead to excessive heat generation, reduced performance, increased energy consumption, equipment failure, safety hazards and elevated maintenance costs. To mitigate these issues, we’ve chosen to utilize USA-made Geroler motors from Eaton, which have proven performance and longevity.
Geroler motors, known for their high efficiency ranging from 90-92%, employ a unique design with minimal moving components, reducing sliding friction and heat generation. This design maximizes torque transmission while minimizing heat generation, thereby optimizing the performance of excavator hydraulic systems. Furthermore, direct drive systems offer advantages over gearboxes. By eliminating numerous parts, such as gears, they reduce issues like excessive vibration, noise, misalignment and leakage.
Direct drive systems also allow for the use of heavier flywheels, enabling more cutting inertia through thick brush. If it is too light, the brush cutter will bog down, increase heat and hurt performance. Our heavy, 145lb flywheel and high torque motor keep the blades cutting with less tendency to slow down when pushing into thick brush and tall grass.
We’ve tested two blades vs three and found three to perform much better with our brush cutters. The two blade system was scrapped and we’ve never revisited it since. We've also heard from dealers that the three blade system outperforms competitor two blade systems. Ultimately, the extra blade performs more cutting per rotation and the heavier flywheel has more inertia to keep it cutting when met with resistance.
When testing and designing, we always consider torque, speed, heat generation, and flywheel weight, which all contribute to maximizing cutting performance.
@@VirnigMfgInc I'll bet it did get better mulching performance with more blades on a direct drive as you are seeing sub 1000 rpm speeds with an 80 cc geroler (
@@VirnigMfgInc one thing that you have to also consider is that when any swinging blade system does not have enough impact to carry through the material for a clean cut, you are introducing variable size and direction of loads to the flywheel that will quickly diminish any torque gains that you realize from direct drive. Direct drive is absolutely ideal, but for small lower flow power units like this, you'd have to use a 40-50 cc geroler motor to get adequate speed. As you probably know, increases/decreases in torque value as it relates to motor displacement are not linear so you'd be looking at a substantially lower torque motor with higher restriction/lower volume motor.
@@wpog8453 Among the many considerations, clip rate stands out as a crucial aspect when it comes to achieving optimal cutting results. Clip rate refers to the frequency at which the blades cross the cutting surface. It is determined by a combination of ground speed, RPM, and tip speed. Increasing the number of times the blades cross the designated area enhances the likelihood of obtaining a high quality cut.
When ground speed decreases, the clip rate increases. This change allows for cutting through heavy materials with improved outcomes, as each revolution removes less material. However, it is important to strike the right balance between ground speed and blade rotation to achieve an efficient cut. Only when the combination of ground speed and blade rotation yields an adequate clip rate can a brush cutter operate optimally.
While manufacturers often emphasize the importance of high tip speeds as a marketing tool, it is essential to recognize that tip speed alone is not as critical as clip rate. Tip speed merely serves as a factor of clip rate. Consequently, a cutter with excessively high tip speed but a low clip rate wouldn’t deliver satisfactory cutting performance.
Consider, for instance, a dual blade cutter with a lightweight flywheel. Such a cutter typically operates at a higher tip speed. However, when coupled with a high ground speed, this configuration results in a lower clip rate. Consequently, the cutter is more likely to struggle and experience low performance when faced with denser vegetation.
Therefore, while tip speed may be highlighted as an indicator of increased cutting speed, it is the clip rate that ultimately determines the effectiveness of the cutter. By designing a balanced combination of flywheel weight, blade length, ground speed, RPM, torque and tip speed, it’s possible to achieve an optimal clip rate and ensure superior cutting performance, particularly in heavier vegetation.
If you are enjoying the conversation, I'd ask you to re-read my last remarks. While what you are saying is correct regarding strikes per minute, I have found that that is not as sufficient of a metric as you suggest. It's not the first time I've heard it either. You are not considering the dynamic loads that you introduce to the fly wheel when your blades have insufficient weight and/or speed to carry through the cut. When your blades glance off of material and flick around and spin (which will frequently happen to some degree) the loads will have a dramatic impact on your projected performance. You are then solely dependant on torque. The problem with that is that this is not an LSHT auger. A small hydraulic power unit simply does not have that kind of torque and a direct drive +/- 80cc motor cannot make up for that. When the system pressure climbs and flow drops dramatically, it compounds this "tumble to the bottom". You are also not considering the fact that mini skid steers and mini excavators have to share a good bit of their total flow with functions that position the cutter. That alone is a good reason to sacrifice a little bit of torque to maintain an adequate speed coming into any given cut. I don't completely disagree with you, I'm just saying that it's not going to yield the best performance on a small power unit. I'm sure your unit is eating great on a KX-080 size unit but with machines toward the middle/lower end of your flow range, what I'm saying will be much more substantial. I know this may be unrealistic for you guys, but I'd be glad to run your V20 mini skid cutter alongside my unit on the same machine and demonstrate what I'm saying if that's something you're ever interested in.
