Earning my stripes! Is this Ventrac the best mower ever made?

What happens here

With the mowing deck detached and the tractor in the shop, the hydraulic fluid change is initiated. The tractor has two main hydraulic fluid reservoirs: a front one that serves the entire hydraulic system (hydrostatic drive, attachments) and a rear one that houses about 4-4.5 quarts of hydraulic fluid for lubrication. The presenter plans to drain both reservoirs and replace the 25-micron and 10-micron hydraulic filters. He shows the special Ventrac Hydro-Torq XL SAE 5W-30 Synthetic Hydraulic Oil required. He prepares two pre-filled filters for installation, emphasizing the importance of hand-tightening plus one full turn after the hand-tight seal.

Goal: The hydraulic fluid change process begins by identifying the two reservoirs and preparing to replace both 25-micron and 10-micron filters with pre-filled ones, using specialized hydraulic oil.

Tools and materials

  • Filter wrenches
  • Oil change bin
  • 10-micron hydraulic filter
  • 25-micron hydraulic filter

What they say

Hide

it in the garage so what we've got to do is we've got a drain plug under the front and a drain plug under the rear the front hydraulic reservoir serves as a reservoir for running all the hydraulics in the machine the hydrostatic drive and everything in the rear is just like a pumpkin basically and the rear just houses about four quarts of uh or four to four and a half quarts of hydraulic fluid to keep everything lubricated do i anticipate the hydraulic fluid being gross maybe it looks a little bit on the brown side it fills up underneath the hood and what you really have to worry about with the ventrac tractor is the fill tube i'm told where you fill up the hydraulic expansion reservoir is ahead of the filter system in other words where you fill it up it's ran through the machine before it runs through the filter system so we're replacing the 25 micron and the 10 micron hydraulic filters which are right there very simple very easy let's get to wrenching and yes i do have a bit of a 90s car problem every car i've got is from the 90s aside from this critter right here i do have a 90s car problem what can i say i'm living in high school so we're going to break out the oil change bin and i'll show you what i do for oil changes i have a specific bin and a way to organize this that's really really helpful this is the car wash bin and this is the oil change bin so and it has oil all over the top of it i must have sprung a leak somewhere so all my stuff for changing oil is in the oil change bin so i don't have to go digging and looking for uh wrenches and and such so we've got our wrenches that we're going to remove our uh two hydraulic filters real quick and the two hydraulic filters will be pre-filled like i said ventrac takes a special oil i think it's a 5w30 synthetic hydraulic oil so here's the ventrac specific 5w30 hydraulic oil 25 micron filter 10 micron filter here goes let's see if we can make a mess
