Product Description

?

This mower deck idler arm service kit is a key component designed to maintain proper tension on the cutting deck belt in riding lawn mowers. It includes a pivoting arm mechanism that presses the idler pulley against the belt, helping ensure smooth power transfer and preventing belt slipping during operation. Constructed from heavy-duty metal for strength and durability, it is built to withstand constant movement and stress under the deck. Ideal for replacing worn or damaged parts, it helps restore consistent cutting performance and reliable belt operation.

Impossible
I looked and looked and finally I discovered e replacement parts and that they had the odd little part I needed. Then I realized that it was very reasonably priced and the shipping was really cheep too. Plus they had a few different shipping options. They got that part to my door in 4 days, and they got my part right. This place is awesome. They could not have made me happier. This place is better in every way then any other place or web site I have been to before. I wish I cod give them 6 stars.
