Item as advertised.
This item goes on my MTD chipper. Not really much to say. It keeps the discharge chute from moving so I can make mulch for my wife's many plants. It was delivered relatively quickly.

hard to find parts
was so easy to order. Had the parts for a Craftsman that could not be found locally. Shipping cost was fair. Have EReplacementParts on my favorite list as I am sure I will ordering from them again.

the chipp[er wasn\'t used for over two years - lots of rust.
1. Checked gas and oil. Added some fresh gas - oil was OK.
2. Choked and pulled the starter cord. Engine turned over but cord didn\'t retract.
3. pulled engine cover off and sprayed WD-40 on end of snout. Balls freed up. Replaced the cover and pulled cord twice and the engine started. I let it run for 10 minutes.
4. The
... Read moredischarge chute hand knobs were totally rusted solid. I used a zip disk to remove then drilled out the remaining threaded part and ran a tap to establish new the threads.
5 Ordered a pair of hand knobs. Made a pair of temporary pieces from 5/16 bolts with a 2 inch piece of 1/4 inch round rod welded on the head.
6. I changed the direction of the discharge chute so it was more parallel with the ground. I modified the top of the chute by cutting each side at 2 inch intervals so I could flatten the top.
I made new sides from a piece of old washing machine sheet metal, drilled 3/8 inch holes along the top edge to plug weld them to the top piece. I cut the grooves to line up with the adjustment knobs. Sanded piece with a flap wheel then two coats of Rust-oleum.
