Wheel loader pairing up with lightweight forestry mulcher, can it work ?.

[Arkan]

@Industrial Toys My largest tractor is New Holland tvt 190,it doesn't matter.Because mulcher we need for our farms can't do this job of mulching high brush ,(or idk anymore how to call em honestly),from ground level,behind tractor ,pushing it backwards.For that job we would need heavy forestry mulchers,but first those are expensive,second our loader surely can't power them(or hey,they for example need 150hp for 2 meters wide ,but 150hp for mulching stumps ,trees yes?.It woudn't pull 150hp to mulch branches and bushes i am sure of it),third we wont have use of em later on our fields.

@Rustyiron I did understood you ,but that equipment would be expensive,in that case it would surely be cheaper if we would just pay some company to do job for us,but this year,or next year,we still need to buy some lightweight mulcher for our tractor .We try to include that type of mulcher for this job,but it would work only on loader for that high bush jungle.

@oldnslo Yup ,it would probably lose speed,for a few seconds ,but we would not change height that often.Besides loader have 3 pumps for hydraulics,idk how those works honestly.We know main one is 260l/min ,140-160 bar,other 2 are i think 160l/min at up to 200 bars,all are gear ones.
Ah yes,loader not have hydraulic oil coolant but we will add it ,my friend today found some company here that are disassembling damaged,old,burned or simillar, excavators ,10-20-30 tons ,many of them.And those machines have very good oil coolers...or he say like that.

Edit:What type of hydraulic motor is best ?,since we need low rpm 450-550 ,should we go for some piston radial type ,he have highest torque ,or so google say ,or any type ?,like piston axial,gear type.

Arkan, you've got a neat project you are thinking about there Maybe someone has already mentioned this, but the mulcher might need a special pump to run it. It would be a low presure, high volume type. The Pisten Bully's I've operated in the past, had 5 diffrent pumps for the various needs it has. Yes, pumps and motors are very specialized. Good luck!

Arkan,
for the 500 - 550 RPM range the most common style of motor used in the USA would be a low speed high torque geroler or geroter type. Common brand in the USA is Eaton Charlynn not sure what brands are common in Europe. Just make sure the motor is rated for your pump pressure and desired operating RPM.

Gear motor might work but they typically are not used for that low of RPM range range.

Radial piston in the 500 cc per revolution might not operate at 500 - 550 RPM. They are usually a lower RPM motor 350 - 400 RPM for that displacement.

Axial piston in that size will be big and expensive.

It is very hard to find exact motor to fit this pump specifications (140-160 bar-260 liter per minute,133 cm3 displacement) ...mainly problem is in low pressure that loader pump are working with,we have flow ,even more than is needed.Most of the hydraulic motors i find for sale here,even some new ,they require 250-300+ bars (3600+ psi).

Arkan,
If motor is rated for higher pressure than your system that is fine. You do not want a motor rated for lower pressure than your system. The rating is the maximum pressure for that motor not the minimum.
