Instal bigger hydraulic pump and big oil reservoir homemade 

Last year we have try to run our harvester on hydraulic motor but tractor hydraulic pump was to small,it has small RPM on hydraulic motor,so we decide to buy bigger pump so we have to make new frame for pump and big reservoir from scrap metal and plumbing parts,again brother has welded everything and after that we have painted,put oil in reservoir,it goes over 25l of hydraulic oil,so i am sure it will not heat,but just in case brother and i have welded small metal strips on one side so we can mount 12v dc fan to cool the oil,as you can see it works perfect,it can be used for log splitter or anything that has hydraulic motor,my next project is manure spreader,i will use that hydraulic motor to turn the back rotator to spread manure,and this year we will try to run our harvester without pto shaft from tractor,it will turn hydraulic motor connected on harvester,greeting to you all
