The owner shows the main and transmission hydraulic filters, the fill location, the filter wrench needed, and points out exactly where the sight glass sits so you can confirm it's full. Useful for someone mid-service who just needs that one answer, not a full 50-hour service walkthrough.
Posted by an L2501 owner doing their own maintenance, sharing a quick fix after struggling to find this info elsewhere.
It is on the passenger side of the tractor. There is no dipstick, so you check the fluid level by looking at the sight glass to see when it is full.
The main hydraulic filter is on one side, and the transmission filter, which is yellow, is on the other side, making it easy to identify.
An oil filter socket wrench, specifically an 80 over 15 size, is used to get into the tight space around the filters.
