Machine Builders Network+ Forums Machine Builders Network Skid Steer / Attachment Builds new blades for Mower King skid steer mower

the gearbox on the mower only has a 1/2" npt port for adding oil. the owners manual states add 'oil' thru the port..with no mention of what viscosity to use..typical chinma manual.
for now the synthetic 80w90 will do it,the seals just have a seep to them,class 1 leak. I'll reinvestigate it in the spring
