When I removed my backhoe this fall and installed the snow blower in preparation for the winter season I observed that the blower would raise up normally, but when I lowered the hitch control lever to lower the blower into operating position, I could barely see it moving. Gets a little better after the hydraulic oil warms up, but not very much. Had hydraulic system serviced at the shop this summer, but had not used the 3 point hitch until mounting the blower. Backhoe worked fine. I am worried that the hitch will quit lowering altogether and I will not be able to use the snow blower to clear my access road and driveway (about 1/2 mile). My questions; what could be causing this problem, (hydraulic valve issue, maybe?) and is there anything I can do to correct it short of taking it to town to the service shop (very hard to do in winter with snow on roads, etc.) Thanks in advance for any help you can give me!
