These electric lawn/garden tractors were made in the early 70's. There are many still around, especially in the North-East U.S. Attachments included snow blowers, plows, snow blades, roto tillers, mower decks, fork lift, rotary inverters (true sine wave), welder, and much more.
I use mine to mow 3 acres using approximately 4.5-5 KWH to recharge the 6 6 volt GC2 (golf cart sized) batteries. These are heavy duty machines and I estimate the weight at around 900 lbs.
My only regret is that it does not have a manual locking differential.

Two key pieces of key info: 1. Machine overloaded. 2.Water not being pumped out.
Most likely something has gotten over the inner tub and is between the inner tub and the outer tub. This is usually a small piece of clothing like a sock etc. This is blocking the entrance to the pump and not allowing the washer to fully drain and hence the slow spin due to water resistance on the inner tub.
Hopefully it is only blocking the entrance and has not fully entered the water pump assembly and wrapped itself around the pump impeller.
This was a common problem when I worked in laundramats back in the 80's. One attempt is to use a medium sized fishing trebble hook on a cord to snag and extract the offending clothing. This only works if the clothing is NOT wrapped around the impeller.
You should be able to unplug the washer and remove front panel to locate and pinch/squeeze the rubber hose connecting the outer tub to the water pump. If there is an article of clothing, you should be able to feel it. Beware that removing the hose from the water pump inlet will result in a massive dump of the remaining water unless the tub to pump hose is "PINCHED" off securely. There is a special tool for pinching off this hose, but it is fairly expensive. Some auto mechanics/radiator repair shops have this tool ... perhaps to borrow one?  
Happy Trails...
