Honda hs928ta

This machine came to me from my brother. The problem he reports is intermittent drive. If he pushes it a bit he can get it to drive a bit but it doesn't maintain drive. Both forward and reverse. Where should I be looking first. I've worked on many snow blowers but this is my first with a hydrostatic drive. It has tracks instead of wheels.

Thanks
Lefty.

Seems like the right transmission/gear case needs some attention, one of the gears in there might be missing a few teeth.

As JnC says sounds like a right transmission over haul.

If it has a way to check the hydraulic fluid level, I would start with that. After adding any necessary fluid, if it's still having trouble, find out if there's a way to purge the hydrostatic unit of air. If you get air in it, that can cause trouble.

This may be worth a read, as just one reference:

There is fluid in the reservoir. I think starting with air purging sounds like an easy first step, if it is possible, before I take anything apart. Also, the control cable doesn't feel very smooth so I'm thinking I'll start there as well. Maybe it's just not actuating the drive?

One thing that you can do is place the blower on some 2x4 or blocks of wood, so the the tracks are up in the air (or place the unit in service position). Try to manually turn the tracks forward and backwards with the transmission lever on ''disengaged', if they skip on any direction your problem is on the side transmission.

Thanks guys. I got a chance to take a look at this today and I think I pinned it down. It looks like the drive belt is gone. When I engage the drive I can see that the belt does not move right away, it just slips. It will occasionally catch and the machine will lurch forward. Upon closer inspection, the belt is very loose. I can pinch it around the engine pully and touch both sides together and there still isn't a great deal of tension on it.

So good news / bad news. I think it's an easy fix but while trying to remove one of the more difficult bolts to access in order to split the machine in half, I mangled it a bit and can't figure how to get it out. There are three bolts on either side vertically, 2 on the bottom at the belly and 2 on top that have to be removed to split the machine...i think. The middle one on the left side is very difficult to get to because of the track, which is in the way of getting a socket on there. I had to use a box end wrench and it eventually slipped and rounded a bit. I then tried a pair of vice grips with no luck. I'm thinking if I can remove the track, I can maybe pound a socket on there and get it out. But I can't find anything on removing the track. Am I going down the wrong road here? Forgive my rookieness.

you do NOT have to split machine in half to replace the drive belt. only the auger belt.

go underneath and remove the 2 little bolts for the belt guide on bottom. take belt off bottom pulley wheel and pull out from top. I just pull auger belt off the top wheel and pull the start coil a little to work the belts forward ( unplug spark plug before doing this )

the first time i did it , it took awhile but is fairly simple. but now i can do it in about 5-10 minutes. after you put new belt on , put guide back on. and adjust drive cable if necessary ( probably is )
