Hello everyone, I am starting from scratch on an MTD 990 with the hopes of getting it to mint running condition. The goal is to make this tractor my 2 acre Garden work horse.

Couple issues with the Tractor itself already is that it wont start not even a Click, Guessing it is a solenoid gone bad. When i bridge the solenoid i can get it to crank but not start.

Issue two is that the hydraulic cylinders for the 3pt lift are leaking a little. Enough to drop the arms over a little bit of time. ( I had the tractor started when i first bought it)

Welcome to the forum. Great looking 990. Looks to be a 1980 to 1983 model. Do you need a manual? If so, DL one from my MS Onedrive.

The B&S service manual is good to have also and your 42" QD mower deck.

Try jumping 12v to the small terminal. That will determine if the solenoid is bad. More likely one of the 2 safety switches is not working or the key switch is bad. Use caution if replacing the key switch. Use only a magneto type switch.

The lift cylinder can be repaired with new o-rings. Look back in the posts to find where another owner has the same issue.

Ended up being the solenoid that was bad, she was a little melted. I was then able to get it running until i tried to wire in some new lights for it... i cant get the lights to turn on and i'm not sure what electrical diagram to go with. The cords are blue and green but the lights aren't wanting to turn on and neither is the tractor now. :/

The diagram in the 1980 or newer manual will be the correct one.
